Maintenance

Very little maintenance is required to keep your CobraMarine VHF radio in good
operating condition.

Keep the radio clean by wiping with a soft cloth and mild detergent.

Rinse with fresh water. 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, rinse it in fresh water at least once

a day to prevent buildup of salt deposits, which could interfere with
button operation.
