Cobra suggests you maintain the low power setting for short-range communications 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 1 watt. High/Low Power Button To Toggle Between The High And Low Power Modes: Press the High/Low Power button. The LCD will show which mode is in effect. High/Low Power Some channels are restricted to use at a maximum of one (1) watt. Your radio will automatically set the power to Low Power mode when you select those channels. While using the U.S.A. channel map, if, in an emergency, you need to increase the output power on Channel 13 and Channel 67 for your signal to be heard, you can override the Low Power mode by pressing and holding the High/Low Power button.
