Operating Your Radio

Maintenance and Troubleshooting

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.
