Operating Your Radio

Maintenance

•

Very little maintenance is required to keep your CobraMarine VHF/GMRS 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.
