Cat B25 Phone User Manual 27
Using Connectors and Ports: Never force a connector into a port. Check for obstructions
on the port. If the connector and port don’t join with reasonable ease, they probably don’t
match. Make sure that the connector matches the port and that you have positioned the
connector correctly in relation to the port.
Accessories and Wireless Performance: Turning on Airplane Mode on Cat B25 may eliminate
audio interference between Cat B25 and an accessory. While Airplane mode is on, you
cannot make or receive calls or use features that require wireless communication. Under
some conditions, certain accessories may affect Cat B25 wireless performance. Reorienting
or relocating Cat B25 and the connected accessory may improve wireless performance.
Keeping Cat B25 Within Acceptable Temperatures: Cat B25 is designed to be operated in
temperatures between 0º and 35º C (32º to 95º F) and stored in temperatures between -20º
and 45º C (-4º to 113º F). Low- or high-temperature conditions might temporarily shorten
battery life or cause Cat B25 to temporarily stop working properly. Leaving Cat B25 in a
parked vehicle or in direct sunlight can cause Cat B25 to exceed these storage or operating
temperature ranges. Avoid dramatic changes in temperature or humidity when using Cat
B25 as condensation may form on or within Cat B25.
When you’re using Cat B25 or charging the battery, it is normal for Cat B25 to get warm. The
exterior of Cat B25 functions as a cooling surface that transfers heat from inside the unit to
the cooler air outside.
Exposure to Radio Frequency: Energy Cat B25 contains radio transmitters and receivers.
When on, Cat B25 receives and sends out radio frequency (RF) energy through its antennas.
The Cat B25 cellular antenna is located at the bottom edge of Cat B25, to the left of the
Home button. The Wi-Fi and Bluetooth® antenna is located at the top edge of Cat B25, to the
right of the headset jack.
For optimal mobile device performance and to be sure that human exposure to RF
energy does not exceed the FCC, IC, and European Union guidelines, always follow these
instructions and precautions: When on a call using the built-in audio receiver in Cat B25,
hold Cat B25 with the dock connector pointed down toward your shoulder to increase
separation from the antenna. When using Cat B25 near your body for voice calls or for
wireless data transmission over a cellular network, keep Cat B25 at least 15 mm (5/8 inch)
away from the body, and only use carrying cases, belt clips, or holders that do not have
metal parts and that maintain at least 15 mm (5/8 inch) separation between Cat B25 and the
body.
Cat B25 is designed and manufactured to comply with the limits for exposure to RF energy
set by the Federal Communications Commission (FCC) of the United States, Industry
Canada (IC) of Canada, and regulating entities of Japan, the European Union, and other
countries. The exposure standard employs a unit of measurement known as the specific
absorption rate, or SAR. The SAR limit applicable to Cat B25 set by the FCC is 1.6 watts per
kilogram (W/kg), 1.6 W/kg by Industry Canada, and 2.0 W/kg by the Council of the European
Union. Tests for SAR are conducted using standard operating positions (i.e., at the ear and
worn on the body) specified by these agencies, with Cat B25 transmitting at its highest
certified power level in all tested frequency bands. Although SAR is determined at the
highest certified power level in each frequency band, the actual SAR level of Cat B25 while
in operation can be well below the maximum value because Cat B25 adjusts its cellular
transmitting power based in part on proximity to the wireless network. In general, the
closer you are to a cellular base station, the lower the cellular transmitting power level.
Cat B25 has been tested and meets the FCC, IC, and European Union RF exposure
guidelines for cellular, Wi-Fi, and Bluetooth operation.
Cat B25’s SAR measurement may exceed the FCC exposure guidelines for body-worn
operation if positioned less than 15 mm (5/8 inch) from the body (e.g., when carrying Cat
B25 in your pocket).
If you are still concerned about exposure to RF energy, you can further limit your exposure
by limiting the amount of time using Cat B25, since time is a factor in how much exposure a
person receives, and by using a hands-free device and placing more distance between your
body and Cat B25, since exposure level drops off dramatically with distance.
