Maintenance and
Troubleshooting
Operating Your Radio
Maintenance
Very little maintenance is required to keep your CobraMarine
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.
