Transmit Power Output
•
Your radio can Transmit selectively at 1 or 25 watts of power. 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.
