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 build-up 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 so if you are using alkaline batteries.
