75-440 User manual

,Use only authorized batteries and chargers. The use of non-authorized accessories may cause burns, fire or explosions causing serious damages to the radio/battery or serious injuries to people.

,Battery chargers are for indoor use only.

,Be certain that your power source matches the rating listed for the supplied battery charger (AC Adapter). If you are not sure, check with your dealer or with your local power company.

,To avoid damaging the power cable of the battery charger, do not put anything on it or place it where it will be walked on. Insert the plug in socket provided with earth connection.

,Avoid strong shocks. Do not use the charger if it received a strong shock, has fallen down or it appears damaged; immediately contact an authorized service station.

,Never try to disassemble or service the charger by yourself. Always contact your local dealer for assistance.

,To reduce the risk of electric shocks disconnect the plug before providing any cleaning or maintenance. Grasp the plug (not the cable) to remove the plug from the socket. The use of non-suitable extension can cause fire or electric shocks.

,Do not expose batteries directly to temperatures below -20°C (-4°F) or greater than 35°C (95°F) during their use and do not charge them outside the range of +5 to +55°C.

Radio maintenance

Cleaning battery packs

Wipe the battery contacts with a clean and lint free cloth to remove dirt, grease or any other material that may prevent a good electrical contact. If contacts are very dirty you can also wipe them using a soft pencil rubber (not hard erasers for ink!). If you feel that battery contacts aren’t still working properly, please contact your authorized dealer.

,Do not use liquid, alcohol or aerosol cleaners.

Cleaning the radio

Wipe the radio with a clean and lint free cloth to remove dust. If it is very dirty, you can use a damp (slightly moistened with water) cloth.

,Do not use liquid, alcohol or aerosol cleaners.

If you normally use your radio in dusty or hard environments, we do recommend using the optional carrying case. Please see “Optional accessories”.

Connectors

When the connectors are not being used, they should be fitted with the supplied cover caps.

,Only suitable accessories must be connected to the related connectors.
