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.
