When a signal is received in SCAN mode, the radio will pause 10 seconds before resuming SCAN operation. The scan will stop when the Talk button is pressed.

Memory channels need to be saved to effectively enter the Memory Channel mode and scan all memory channels. See page 25.

High/Low (HI/LO) Power Button

Your radio can transmit selectively at 1 or 3 watts of power. Cobra suggests you maintain the low power setting for short-range communication. You will conserve battery life and avoid overpowering nearby stations by using a low power signal. Use the High Power setting for long-range communications or when you do not receive a response

to a signal sent at 1 watt.

To Toggle Between HI/LO Power Modes:

Press the Power Level/Weather button. The LCD will show which mode is in effect. Some channels are restricted for a maximum use of 1 watt. Your radio will automatically set the power to Low Power mode when you select those channels.

NOTE

Some channels, frequency bands and countries of use might not be able to operate in High Power mode.

If the radio is in the Key Lock mode, the channel will not change and the three (3) beep error signal will sound.
