5. Fully charge the battery and check the battery capacity. If
you believe some memory effect still exists go back to step
1.

If the battery capacity does not improve after performing
steps 1-5 three times, your battery pack is faulty or has
reached the end of it’s life.
Cleaning your radio
Wipe the radio with a clean cloth to remove dust. If it is very dirty,
you can use a damp cloth.
Clean the battery contacts with a clean, lint-free cloth to remove
dirt, grease or any other material, which 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 still aren’t making good electrical
contact, please contact your dealer or communications
coordinator.

Do not use liquid, alcohol or aerosol cleaners.
