If your Motorola Radio will not turn off, the controller board may be defective. Send the radio to a depot.
What to do if my Motorola ASTRO XTS 3000 Radio will not turn off?
If your Motorola Radio will not turn off, the controller board may be defective. Send the radio to a depot.
Why is the audio distorted or not loud enough on my Motorola ASTRO XTS 3000 Radio?
If your Motorola Radio's audio is distorted or not loud enough, check the synthesizer frequency by measuring the transmitter frequency. If it's off by more than ±250 Hz, realign it.
