Maintenance
Very little maintenance is required to keep your CobraMarine
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.
