Battery operation
1. Release the catch securing the rear door of your radio.
2. Insert four LR20 (D size) batteries into the spaces in the compartment.
Take care to ensure all batteries are inserted with the correct polarity
as shown inside the battery compartment. Close the rear door and
secure the catch.
3. Reduced power, distortion and a ‘stuttering’ sound are all signs that
the batteries may need replacing.
4. If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
We would recommend for economy that the radio is used via the AC
adaptor whenever possible with battery operation for occasional or
stand-by use only.
Using the AC adaptor
1. Insert the adaptor plug into the DC in socket on the rear of your
radio.
2. Plug the adaptor into a standard 13A mains socket outlet. Whenever
the adaptor is used the batteries are automatically disconnected.
The AC adaptor should be disconnected from the mains supply and
the radio when not in use.

Radio operation
Your radio is equipped with three wavebands to enable you to select the
programme of your choice. The FM band uses an external telescopic aerial
which should be fully extended and rotated for best reception. MW and LW
bands are received by an internal aerial which is directional. To achieve
the best reception, it may be necessary to rotate the radio.
1. Switch on the radio by rotating the volume control clockwise until a
click is heard.
2. Depress the appropriate waveband button for FM MW or LW as
required.
3. Tune to the desired programme by adjusting tuning control. On MW
and LW the tuning scale is marked in kilohertz (kHz) and on FM in
megahertz (MHz).
4. Adjust the volume and tone controls to the desired tone and sound
level. Depressing the tone control button reduces high frequencies
(treble).
Headphones
A3.5mm socket is provided for use with either headphones or an earpiece.
Inserting a plug automatically mutes the internal loudspeaker.

Display backlight
1. When your radio is powered by the AC mains or the batteries the
display backlight will always be switched on.
Care
For external cleaning use only a soft clean cloth. Use a damp cloth to
clean the cabinet. A mild soap will help remove grease or oil. Never
use strong detergents, spray cleaners, abrasive powders, thinners or
solvents as these may cause damage to the radio.
General
Do not allow this unit to be exposed to water, steam or sand. Do not
leave the unit 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.
