Important Information - please read before use

To assist the auto setup of your radio it is recommended that, before connecting your radio to a power supply (batteries or mains), you fully extend the telescopic aerial and place your radio in a position where radio reception is best.

note : the two LR6 (AA size) batteries provide power for the clock/memory backup and must be fitted at all times.

Automatic FM setup

When your radio is first connected to a power supply (batteries or mains) or after a power failure (when backup batteries are not installed), the Auto setup will automatically search the FM waveband and store stations in presets.

1. Install batteries or connect to mains (see page 6). Your radio will show start searching the FM waveband.

2. Your radio will automatically switch off and return to time display when setup is complete. (Setting the clock time is described on page

3. Press the On/Off button to switch on your radio and press one of the Preset buttons to select a station.

4. Adjust the volume using the Volume control. To switch off your radio press the On/Offbutton.

Note:- Auto setup can take 3-4 minutes to complete and is dependent on the signal strength and number of stations in your area.

To interrupt the Auto setup press and release the Memo button.

Should Auto setup fail, setting FM pre-setting stations can be carried out manually as described in the following sections.

Troubleshooting

Due to external interference (caused by static charges from carpets, thunderstorms, etc.), the control electronics of your radio could receive bad information. If the display is incomplete or the radio is not responding to control buttons, proceed as follows:-

Remove the power supply (the mains and all batteries) and re-install them again after one minute.

This resets the radio to its initial state. The stored data for the individual memory positions, the clock, the alarm settings and the Last Station Memory are all cleared.

General

Do not allow this radio to be exposed to water, steam or sand. Do not leave your radio where excessive heat could cause damage such as in a parked car where the heat from the sun can build up even though the outside temperature may not seem too high. It is recommended that the FM band be used wherever possible as better results in terms of quality and freedom from interference will usually be obtained than on the MW or LW bands.
