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 were ever possible as better results in terms of quality and freedom from interference will usually be obtained than on the MW or LW bands. Mains adaptor Plug the adaptor into a 13A mains outlet. Plug the lead from the adaptor into the DC socket, located on the rear of Revival models and on the left hand end on Classic models. The battery will be automatically disconnected. The mains adaptor should be disconnected from the mains supply when not in use. Battery Revival models.

Reduced power, distortion, and a ‘stuttering’ sound are all signs that the battery may need replacing.

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 receiver 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 A 3.5mm socket is provided for use with either headphones or an earpiece. Inserting a plug automatically mutes the internal loudspeaker.
