Channel Scan Mode

During Channel Scan mode, the radio will rapidly switch from channel to channel through ALL the channels. Whenever any activity is detected, the radio will stop the scan for 10 seconds to allow you to listen briefly on that channel. The radio will then continue to scan unless you switch out of the Channel Scan mode.

To Enter Channel Scan:

1.From Marine Standby mode, press and hold the

DUAL WATCH/SCAN button. The radio will immediately begin to scan the entire channel map selected in

the active channel map. The SCAN icon will show on the LCD.

2.A signal on any channel will stop the scan for

10 seconds to allow you to listen to the traffic on that location.

3.Press the Channel Up or Channel Down button to resume scanning the Channel Scan channels or to change the scan direction.

4.To EXIT Channel Scan mode, press and hold the DUAL WATCH/SCAN button again. The SCAN icon will disappear from the LCD and the radio will return to Marine Standby mode.

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. 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.
