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 buildup 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 tray and store them in a separate
package. This is especially important if you are using alkaline batteries.
