To Decrease The Volume:

1.Turn the On-Off Power/Volume knob counter-clockwise.

Power Saver

Your radio has a unique circuit designed to extend battery life. If there are no transmissions within ten (10) seconds, the radio will automatically switch to Power Save mode and the Save icon will flash in the LCD. This will not affect the radio’s ability to receive incoming transmissions.

U.S.A./International/Canada Channel Maps

Three (3) sets of VHF Channel Maps have been established for marine use in the U.S.A, Canada, and the rest of the world (international). Most of the channels are the same for all three (3) maps, but there are definite differences (see information on pages 14 to 21). Your radio has all three (3) maps built into it and will operate correctly in whichever area you choose.

To Set Your Radio For The Area

In Which You Will Be Using It:

1.From Standby mode, press and hold the Weather/UIC button for three (3) seconds. The U, I, or C icon will blink on the LCD.

To Change Channels:

Transmit Power Output

Your radio can Transmit selectively at one-half (1⁄2) or two (2) watts of power. Cobra® suggests you maintain the low power setting for short-range communications, to conserve battery life, and to avoid overpowering nearby stations with your signal. Use the high power setting for long-range communications or when you do not receive a response to a signal sent at one-half (1⁄2) watt.

To Toggle Between The High

And Low Power Modes:

1.Press the High/Low Power – Lock button. The LCD will show which mode is in effect.
