Plug Fitting Instructions (UK Only)
The cord supplied with this appliance is factory fitted with a UK mains plug fitted with a 3 amp fuse inside. If it is necessary to change the fuse, it is important that a 3 amp one is used. If the plug needs to be changed because it is not suitable for your socket, or becomes damaged, it should be cut off and an appropriate plug fitted following the wiring instructions below. The plug must then be disposed of safely, as insertion into a mains socket is likely to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires should be fitted as shown in this diagram. The colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug. Connect them as follows: The wire which is coloured BLUE must be connected to the terminal which is marked with the letter ‘N’ or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter ‘L’ or coloured RED. The wire which is coloured GREEN/YELLOW must be connected to the terminal which is marked with the letter ‘E’ or coloured GREEN. If a 13 amp (BS 1363) plug is used, a 3 amp fuse must be fitted, or if any other type of plug is used a 3 amp fuse must be fitted, either in the plug or adaptor, or on the distribution board.

Tuner aerial connections for picking up radio signals. Refer to the ‘Connections’ section of this manual. For permanent use, outdoor AM/FM aerials are highly recommended.
Note: The SR10 is supplied with a temporary aerial for initial use. For permanent use, outdoor aerials are highly recommended.
AM loop aerial
Connect each end of the single length antenna to the antenna terminals. Place the antenna as far from the main system as possible to prevent unwanted noise and to obtain optimum reception. If the AM loop aerial provided does not provide sufficient reception, it may be necessary to use an outdoor AM aerial.
Connect the supplied aerial to the FM 75 ohm socket. Extend and move the aerial lead around until you get the best reception. For continued use, we strongly recommend using a 75 ohm outdoor FM aerial.
The use of A and B speakers affords you an easy and inexpensive way to create a simple multi-room system. Note: When using two pairs of speakers, use speakers with a nominal impedance of 8 ohms.
2 Headphones socket Allows for the connection of stereo headphones with a ¼ inch jack plug. Headphones with an impedance of between 32 and 600 ohms are recommended.
Note: Plugging in headphones will automatically mute the loudspeaker outputs.
The skip scan buttons are used when the FM/AM tuner is selected. These buttons have different uses depending on the mode selected: In Preset mode - Steps up or down through the user-stored presets.
In Auto mode - Searches for the previous or next available station. The unit stops at the next strong signal it finds. In Manual mode - Allows manual stepping up or down of the frequency.
Note: When Preset mode is activated, the unit will automatically tune to the first available preset.
Used for AM/FM mode. Press to cycle the tuning mode between Preset, Auto, and Manual modes. Pressing and holding the button will allow the current selected station frequency to be stored in the preset bank.

An unobstructed line of sight between the remote control and the sensor is required. Use to increase or decrease the level of the sound from the outputs of the unit. This controls the volume level of the loudspeakers, Sub-out and headphones. It does not affect the level of the ‘Rec Out’ output. The volume control will also change the level of bass, treble and balance in the menu options. This source input allows you to connect a portable audio device such as an MP3 player directly into the front of the unit using a 3.5mm stereo-jack. Once plugged in, this input is automatically selected, although other inputs can still be selected once a stereo-jack is plugged in. The MP3/AUX button on the front of the unit will select this input whilst a stereo-jack is plugged in.
– Plugging a source into the front panel MP3 input overrides the Aux input. Simply remove the jack from the front panel to automatically re-enable the Aux input. – Also note that as the output level of MP3 players tends to be quite low, the SR10 adds 10dB to the current volume setting when (and only when) the MP3 input is selected.
