Getting Started

High/Medium/Low (H-M-L) Power Button

Your radio can transmit selectively at 1, 3 or 6 watts of power. Cobra suggests you maintain the low power setting for short-range communications. You will conserve battery life and avoid overpowering nearby stations with a low power setting 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 H-M-L Power Modes:

Press the H-M-L Power 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.
