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.
