    Introduction
    The FT-250R is an ultra compact FM hand-held providing up to five watts of RF power
    and a wealth of convenient features for the 2m amateur band. The FT-250R has rubber
    gasket seals around all external controls and connectors to help keep out dust and rain or
    spray, assuring years of reliable operation even in harsh environments.
    Sixteen multi-function keys provide the ultimate in programmability, with 199 freely tunable memories and two VFOs. All memories store repeater shifts or separate tx/rx frequencies, CTCSS (Continuous Tone Controlled Squelch System) or DCS status. You also
    get one instant-recall “Home” channel memory and ten special purpose memories for
    limited subband tuning/scanning. Busy channel band or selective memory scanning is
    provided along with priority channel monitoring; 1 MHz up/down stepping; ARS (automatic repeater shift) when tuned to repeater subbands; plus a top panel rotary dial for
    memory and frequency selection. The keypad serves as a DTMF encoder during transmission, and up to 9 DTMF memories can store 16 digits each for quick playback of commonly used numbers.
    The liquid crystal display shows seven frequency digits, memory selection, CTCSS tone
    frequency, and includes a bargraph S/PO meter. Yaesu’s power saver system can be set by
    the operator for optimum sampling/standby ratio, or can be turned off for packet operation. And our new APO (Automatic Power Off) system shuts off the transceiver to avoid
    dead batteries if you doze off or are called away unexpectedly.
    Operation under difficult conditions is simplified by a lamp button illuminating the display and backlit translucent keypad, diatonically assigned function-dependent keypad beeps.
    Please read this manual carefully to gain a full understanding of the features of the
    FT-250R.

    Basic Operation
    BATTERY PACK INSTALLATION AND REMOVAL
    To install the battery, hold the transceiver with your left hand, so your palm is over the
    speaker and your thumb is on the top of the belt clip. Insert the battery pack into the
    battery compartment on the back of the radio while tilting the Belt Clip outward, then
    close the Battery Pack Latch until it locks in place with a “Click.” To remove the battery,
    turn the radio off and remove any protective cases. Open the Battery Pack Latch on the
    bottom of the radio, then slide
    the battery downward and out
    Tilt the Belt Clip
    Insert the Battery Pack
    from the radio while unfolding the Belt Clip.
    Do not attempt to open any of
    the rechargeable Ni-MH
    packs, as they could explode
    Close the
    Battery Pack Latch
    if accidentally short-circuited.

    BATTERY CHARGING
    If the battery has never been used, or its charge is depleted, it may be charged by connecting the PA-38/CD-30 Desktop Charger.

    c Insert the DC plug from the PA-38 AC Adapter into the DC

    jack on the bottom side of the CD-30 Desktop Charger, then
    plug the PA-38 AC Adapter into the AC line outlet.
    d Insert the battery pack into the CD-30 Desktop Charger while
    aligning the slots of the battery pack with the guides in the nest
    of the CD-30; refer to the illustration below for details on proper
    positioning of the pack. If charging with the transceiver attached, turn the transceiver off, and the antenna jack should be
    at the left side when viewing the charger from the front.
    If
    e the battery pack is inserted correctly, the LED indicator will
    glow red (Charging).
    A fully-discharged pack will be charged completely in
    approximately 3 hours.
    f When charging is completed, the red LED indicator will
    change to green (Fully Charged). Disconnect the pack
    from the CD-30 Desktop Charger, and unplug the PA38 AC Adapter from the AC line outlet.
    Align the slots of the battery pack
    with the guides in the nest of the
    CD-30 Desktop Charger.

    Basic Operation
    Important Notes!
    Do not connect an improper AC Adapter. Use only the supplied PA-38 AC Adapter.
    Do not charge an improper battery (one not specifically designed for use in the
    PA-38/CD-30).
    Disconnect the pack from the CD-30 Desktop Charger, and unplug the PA-38 AC
    Adapter from the AC line outlet, when charging is completed.
    The PA-38 AC Adapter and/or CD-30 Desktop Charger will generate a moderate
    amount of heat during the charging process. This is a normal condition.
    The PA-38/CD-30 is designed for charging only, and is not designed for operation
    (transmission/reception) of the transceiver.
    Periodically wipe the charging terminals in the nest in the charger stand, using a dry
    cloth, to ensure good connections between the charger and battery.
    Caution!!
    When charging a battery pack alone (not attached to the transceiver), do not allow any
    metal object to short the terminals on top of the pack.
    Do not allow any metal objects to short the terminals in the nest of the charger stand,
    as a short-circuit could cause overheating of the charger circuitry.

    ANTENNA INSTALLATION
    The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced coverage in remote areas, an external mobile or base station antenna may prove beneficial.

    To install the supplied antenna
    Hold the bottom end of the antenna, then screw it onto the
    mating connector on the transceiver until it is snug. Do not
    over-tighten by use of extreme force.
    Notes:
    Never transmit without having an antenna connected.
    When installing the supplied antenna, never hold the
    upper part of the antenna while screwing it onto the
    mating connector on the transceiver.
    If using an external antenna for transmission, ensure that the SWR presented to the
    transceiver is 1.5:1 or lower, to avoid excessive feedline loss.

    FT-250R OPERATING MANUAL

  • Page 10

    Basic Operation
    SWITCHING POWER ON AND OFF
    c Be sure the battery pack is installed.
    d Connect the antenna to the top panel ANTENNA jack.
    e Switch on the transceiver by rotating the VOL control
    clockwise out of the click-stop (a momentary beep will
    sound).

    ADJUSTING THE VOLUME LEVEL
    Rotate the VOL control (immediately to the right of the Antenna) to set the desired audio
    level. Clockwise rotation increases the volume level.

    SQUELCH SETUP
    Set the SQL control fully counterclockwise, rotate the VOL
    control out of the click-stop and adjust for a comfortable
    volume on the noise or received signal. The BUSY/TX
    indicator LED should glow green. If a signal is present,
    rotate the DIAL selector on the top panel to a channel where
    only noise is heard.
    Adjust the SQL control just to the point where the noise is
    silenced and the LED is extinguished. If the SQL control is set further clockwise, sensitivity to weak signals will be reduced. Now, whenever a signal reaches the receiver that is
    strong enough to open the squelch, the indicator will glow green.

    TRANSMITTING
    When you wish to transmit, wait until the channel is clear (BUSY/TX lamp off), and
    squeeze the PTT switch. During transmission the BUSY/TX indicator glows red, and
    relative transmitter power output is indicated graphically along the bottom of the display.
    Release the PTT switch to receive.
    If using a “B” version (in Europe), press the
    T-CALL switch (just below the PTT switch)
    to transmit a 1750 Hz tone to access repeaters that require it.

    For working on repeaters with odd splits, or communicating with astronauts on orbiting
    space vehicles, it may be necessary to use non-standard splits between the receive and
    transmit frequency. If the application is infrequent enough not to warrant the dedication of
    a memory channel for this purpose, the “VFO Split” mode may be used. Here is the procedure:

    c Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the receiving

    frequency (for example, 144.950 MHz).
    d Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit frequency
    (e.g. 144.750 MHz).
    e Press the [VFO(PRI)] key once more to re-establish VFO-A as the “Main” (receive)
    VFO.
    f Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.

    k If you need to modify the VFO-B (transmit) frequency (for Doppler Shift correction,
    etc.), just press the [VFO(PRI)] key, then make the necessary change, then press
    [VFO(PRI)] key once more to restore VFO-A to the “receive VFO” position.
    When
    you have finished with Split operation, re-enter the Set mode, and set Menu #5
    l
    to OFF.
    A split frequency pair set up via the VFO Split feature cannot be stored directly into
    memory. You can, however, store odd frequency pairs using a different (slightly simpler)
    procedure. See page 18.

    RECEIVE BATTERY SAVER SETUP
    An important feature of the FT-250R is its Receive Battery Saver, which “puts the radio
    to sleep” for a time interval, periodically “waking it up” to check for activity. If somebody
    is talking on the channel, the FT-250R will remain in the “active” mode, then resume its
    “sleep” cycles. This feature significantly reduces quiescent battery drain, and you may
    change the amount of “sleep” time between activity checks using the Menu System:

    c Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.

    When you are operating on Packet, switch the Receive Battery Saver OFF, as the sleep
    cycle may “collide” with the beginning of an incoming Packet transmission, causing
    your TNC not to receive the full data burst. Likewise, during voice operation, part of the
    first word of an incoming transmission may be cut off during (normal) Battery Saver
    operation.

    TX BATTERY SAVER
    The FT-250R also includes a useful Transmit Battery Saver, which will automatically
    lower the power output level when the last signal received was very strong. With the

    CTCSS OPERATION
    Many repeater systems require that a very-low-frequency audio tone be superimposed on
    your FM carrier in order to activate the repeater. This helps prevent false activation of the
    repeater by radar or spurious signals from other transmitters. This tone system, called
    “CTCSS” (Continuous Tone Coded Squelch System), is included in your FT-250R, and
    is very easy to activate.
    CTCSS setup involves two actions: setting the Tone Frequency and then setting of the
    Tone Mode. These actions are set up by using the [1(SQ TYP)] and [2(CODE)] keys, or
    Menu Items #25 and #26.

    c Press the [F/L] key, then immediately press the [1(SQ TYP)] key. This provides a

    SQL TYP

    DCS OPERATION
    Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
    advanced tone system which generally provides more immunity from false paging than
    does CTCSS. The DCS Encoder/Decoder is built into your FT-250R, and operation is
    very similar to that just described for CTCSS. Your repeater system may be configured for
    DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use transceivers equipped with this advanced feature.
    Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that
    you select a tone code.

    Advanced Operation
    TONE SEARCH SCANNING
    In operating situations where you don’t know the CTCSS or DCS tone being used by
    another station or stations, you can command the radio to listen to the incoming signal and
    scan in search of the tone being used. Two things must be remembered in this regard:
    You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
    Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
    transmitting on the repeater uplink (input) frequency in order to allow Tone Search
    Scanning to work.
    To scan for the tone in use:

    c Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-

    T SQ
    sion). In the case of CTCSS, “T
    SQ” will appear on the display; in the case of DCS,
    DCS
    “DCS

    d Press the [F/L] key, then immediately press the [2(CODE)] key to select the “TN
    DCS SET
    Menu item (when TONE SQL is selected) or “DCS
    SET” (during DCS operation).
    e Press the [F/L] key, then press and hold in the [ (MHz)] or [ (MHz)] key to start
    scanning for the incoming CTCSS or DCS tone/code.
    f When the radio detects the correct tone or code, it will halt on that tone/code, and
    audio will be allowed to pass. Press the [F/L] key to lock in that tone/code.
    g Press the [F/L] key, then press the PTT key to save the new settings and exit to normal
    operation.
    If the Tone Scan feature does not detect a tone or code, it will continue to scan indefinitely. When this happens, it may be that the other station is not sending any tone. You
    can press the PTT switch to halt the scan at any time.
    You also can press the MONI key during Tone Scanning to listen to the (muted) signal
    from the other station. When you release the MONI key, Tone Scanning will resume
    after about a second.

    CTCSS/DCS BELL OPERATION
    During CTCSS Decode or DCS operation, you may set the FT-250R up such that a ringing “Bell” sound alerts you to the fact that a call is coming in. Here is the procedure for
    activating the Bell will ring in accordance with this programming.

    c Set the transceiver up for CTCSS Decode (“TONE SQL”) or DCS operation, as described previously.

    d Adjust the operating frequency to the desired channel.

    Scanning
    The FT-250R allows you to scan just the memory channels, the entire operating band, or
    a portion of that band. It will halt on signals encountered, so you can talk to the station(s)
    on that frequency, if you like.
    Scanning operation is basically the same in each of the above modes. Before you begin,
    take a moment to select the way in which you would like the scanner to resume scanning
    after it halts on a signal.

    Setting the Scan Resume Technique
    Three options for the Scan-Resume mode are available:
    5 SEC
    SEC: In this mode, the scanner will halt on a signal it encounters, and will hold there for
    5 seconds. If you do not take action to disable the scanner within that time period,
    the scanner will resume even if the stations are still active.
    BUSY
    BUSY: In this mode, the scanner will halt on a signal it encounters. Two seconds after the
    carrier has dropped because the other station(s) ceased transmission, the scanner
    will resume.
    HOLD
    HOLD: In this mode, the scanner will halt on a signal it encounters. It will not restart
    automatically; you must manually re-initiate scanning if you wish to resume.

    To set the Scan-Resume mode

    c Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
    RESUME
    RESUME”).
    d Rotate the DIAL to select Menu #7 (“RESUME
    e Press the [F/L] key to enable changing of this Menu item.
    f Rotate the DIAL to select the desired scan-resume mode.
    g When you have made your selection, press the PTT key to save the new setting and
    exit to normal operation.

    The default condition for this Menu Item is “5 SEC”.

    VFO SCANNING
    This mode allows you to scan the entire current operating band.

    c Select the VFO mode by pressing the [VFO(PRI)] key, if necessary.
    d Press and hold in the [ (MHz)] or [ (MHz)] key for 1/2 second to start scanning.
    e If and when the scanner encounters a signal strong enough to open the squelch, the

    scanner will halt temporarily; the decimal point of the frequency display will blink
    during this “Pause” condition.
    f The scanner will then resume according to the Scan Resume selected in the previous
    section.
    g To cancel scanning, press the PTT key.
    If you want to change direction of the scan while it is underway, rotate the DIAL one
    click in the opposite direction (in this case, one click counter-clockwise).

    MEMORY SCANNING
    Memory scanning is similarly easy to initiate:
    c Set the radio to the Memory mode by pressing the [MR/MW(SKIP)] key, if necessary.
    d Press and hold in the [ (MHz)] / [ (MHz)] key for 1/2 second to initiate scanning.
    e As with VFO scanning, the scanner will halt on any signal encountered that is strong
    enough to open the squelch; it will then resume scanning according to the Scan-Resume mode set previously.
    f To cancel scanning, press the PTT key.
    HOW TO SKIP (OMIT) A CHANNEL DURING MEMORY SCAN OPERATION
    When you have some very active channels stored in memories, you may wish to skip them
    when scanning, but still have them available for manual selection.
    Such channels may be “Skipped” during scanning, if you like:
    c Set the radio to the Memory Mode by pressing the [MR/MW(SKIP)] key, if necessary.
    d Rotate the DIAL to select the Memory Channel to be skipped during scanning.
    e Press the [F/L] key momentarily (not for 1/2 second), then press the [MR/MW(SKIP)]
    key (momentarily). A small “SKIP” will appear to the LCD. indicating it is to be
    ignored during scanning.
    To re-institute the channel into the scanning loop, repeat the above three steps (the “Skipped”
    channel will, of course, still be accessible via manual channel selection methods using the
    DIAL in the MR mode).

    PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS)
    This feature allows you to set sub-band limits for either scanning or manual VFO operation. For example, you might wish to set up a limit (in North America) of 144.300 MHz to
    148.000 MHz so as to prevent encroachment into the SSB/CW “Weak Signal” portion of
    the band below 144.300 MHz. Here’s how to do this:

    c Set the radio to the VFO mode by pressing the [VFO(PRI)] key, if necessary.
    d Using the techniques learned earlier, store (per the above example) 144.300 MHz into
    L1 (the “L
    L” designates the Lower sub-band limit).
    Memory Channel #L1

    U1 (the “U
    U” designates the Upe Likewise, store 148.000 MHz into Memory Channel #U1
    per sub-band limit).

    f Switch to the Memory mode by pressing the [MR/MW(SKIP)] key once, then rotate

    the DIAL to select Memory Channel # L1
    L1.

    SMART SEARCH OPERATION
    The Smart Search feature allows you to load frequencies automatically according to where
    activity is encountered by your radio. When Smart Search is engaged, the transceiver will
    search above and below your current frequency, storing active frequencies as it goes (without
    stopping on them even momentarily); these frequencies are stored into a special Smart
    Search memory bank, consisting of 31 memories (15 above the current frequency, 15
    below the current frequency, plus the current frequency itself).
    Two basic operating modes for Smart Search are available:
    SINGLE
    SINGLE:
    In this mode, the transceiver will sweep the current band once in each direction starting on the current frequency. All channels where activity is present
    will be loaded into the Smart Search memories; whether or not all 31 memories are filled, the search will stop after one sweep in each direction.
    CONTINUE
    CONTINUE: In this mode, the transceiver will make one pass in each direction as with
    One-Shot searching; if all 31 channels are not filled after the first sweep,
    however, the radio will continue sweeping until they are all filled.

    ARTS (Automatic Range Transponder System) Operation
    The ARTS feature uses DCS signaling to inform both parties when you and another ARTSequipped station are within communications range. This may be particularly useful during
    Search-and Rescue situations, where is important to stay in contact with other members of
    your group.
    If the other radio is in range, the beeper will sound (if
    IN RNG
    enabled) and the display will show “IN
    RNG” as opOUT RNG
    posed to the out of range display “OUT
    RNG” in which
    ARTS operation begins.
    If you move out of range for more than one minute
    (four pollings), your radio will sense that no signal
    has been received, three beeps will sound, and the disOUT RNG
    play will revert to “OUT
    RNG.” If you move back into range, your radio will again beep,
    IN RNG
    and the display will change back to the “IN
    RNG” indication.
    You must terminate ARTS in order to resume normal operation. This is a safety feature
    designed to prevent accidental loss of contact due to channel change, etc.
    Here is how to activate ARTS:

    ARTS ALERT BEEP OPTIONS
    The ARTS feature allows two kinds of alert beeps (with the additional option of turning
    them off), so as to alert you to the current status of ARTS operation. Depending on your
    location and the potential annoyance associated with frequent beeps, you may choose the
    Beep mode which best suits your needs. The choices are:
    IN RANGE:The beeps are issued only when the radio first confirms that you are within
    range, but does not re-confirm with beeps thereafter.
    ALWAYS: Every time a polling transmission is received from the other station, the alert
    beeps will be heard.
    ARB OFF: No alert beeps will be heard; you must look at the display to confirm current
    ARTS status.

    Interface of Packet TNCs & Reset
    The FT-250R may be used for Packet operation, using the optional CT-44 microphone
    adapter (available from your Yaesu dealer) for easy interconnection to commonly-available connectors wired to your TNC. You may also build your own cable using a fourconductor miniature phone plug, per the diagram below.
    The audio level from the receiver to
    the TNC may be adjusted by using the
    VOL knob, as with voice operation.
    The input level to the FT-250R from
    the TNC should be adjusted at the
    TNC side; the optimum input voltage
    is approximately 5 mV at 2 k-Ohms.

    Be sure to turn the transceiver and
    TNC off before connecting the cables,
    so as to prevent voltage spikes from
    possibly damaging your transceiver.
    Also, be certain to turn off the Receiver Battery Saver, if activated (see page 10).

    MICROPROCESSOR RESETTING
    In the event that erratic, unpredictable transceiver operation is encountered, it is possible
    that the microprocessor has sustained a static burst or other condition that has caused
    corruption of some of its data. If this should happen, resetting of the microprocessor should
    clear up the problem. Here is the procedure for resetting the microprocessor (this will
    restore all factory defaults, and will erase all memories):

    c Turn the radio off.
    d Press and hold the PTT and LAMP key while turning the radio on.

    ALL.RST” on the LCD.
    e Rotate the DIAL to select “ALL.RST
    f Press the [F/L] key momentarily to initialize the radio.

    SET MODE RESETTING
    This “Reset” procedure restores the Menu (“Set mode”) settins to their factory defaults,
    without affecting your regular memories.

    c Turn the radio off.
    d Press and hold the PTT and LAMP key while turning the radio on.

    Cloning
    The FT-250R includes a convenient “Clone” feature, which allows the memory and configuration data from one transceiver to be transferred to another FT-250R. This can be
    particularly useful when configuring a number of transceivers for a public service operation. Here is the procedure for Cloning one radio’s data to another:

    c Turn both radios off.
    d Connect the optional CT-27 cloning cable between the MIC/SP jacks of the two ra-

    dios.
    e Press and hold the PTT and LAMP key while turning the radio on.
