Question about Motorola MU21CV (1 Channel) 2-Way Radio
I Just hear a Hiss Noise when it turns on
It is possible your radio is not programmed, or has a bad/old battery.
It is normal for the side buttons 1 and 2 to beep when depressed to indicate you turned the feature on/off. Each of these buttons has the ability to be programmed a long and a short press feature.
If your radio beeps when your press the PTT button, on any or all channels, it indicates a low or nearly dead battery. Check your battery date code to see if the battery needs replaced.
If your radio emits a long tone on a channel, that channel is not programmed to function.
If your radio beeps a single beep when you turn it on, this is normal.
Charge your radio completely overnight, with the radio turned off. See if this solves the problem. If not, try a new/different battery to see if it will solve the issue. If not, drop by your local dealer and let them look at the unit.
