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.
