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.
