Maintenance
•
Very little maintenance is required to keep your CobraMarine
™
VHF radio in
good operating condition.
■
Keep the radio and charger clean by wiping with a soft cloth and
mild detergent. Do not use solvents or harsh or abrasive cleaners,
which could damage the case or scratch the LCD screen.
■
If the radio is exposed to salt water, wipe with a soft, moist cloth at
least once a day to prevent build-up of salt deposits, which could
interfere with button operation.
■
If the radio will be stored for a long period, such as over the winter,
remove the batteries from the battery compartment and store them
in a separate package. This is especially so if you are using alkaline
batteries.
