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  
programmeofyourchoice.TheFMbandusesanexternaltelescopicaerial  
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.

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).

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.  
The Company reserves the right to amend the specification without  
notice.
