Maintenance

•

Very little maintenance is required to keep your CobraMarine

™

VHF radio

in good operating condition.

■

Keep the radio and adapter/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.
