Is plugged in (both parts) but receiver only beeps

sadly not a clue but perhaps the manufacturer's tech support has the answer you want

the remote did not receive a signal back from the module or the module did not receive the remote signal
Check the battery connections there is a connector plug soldered on the board real close to where the battery is, and if it is hit by the battery hard enough it will cause those solder connections to disconnect and you will get the beeps and or other malfunctions

probably need a new receiver.

With the MSPA this is a code that has something to do with the wire coming from the panel to the control boxCheck the pins to make sure they are not bent and are plugging in correctly.

They are nasty things to use on a dog. Why not use a harness and a long rope to train your dog?

I bought a new one!!!!

Please excuse me if you already have the answer, but I went thru the same thing and found that the actual receiver was broken. The receiver that is found in the top part of the fan itself. I was able to diagnose the problem because I have two of the same fans in the house and when I switched the receiver units, the broken fan started to work. Hope that helps.

Uninstall the audio driver and install it again.
Otherwise tick the mute box on the sound volume or turn the sound volume right down.

your power cable has a short in it. replace it.

I had the same problem.
Here is the solution that I received from Motorola tech support:

1.Delete all messages
2. Unplug the power and re-apply power
3. Quickly press and release << (previous message) and >> (next message) buttons together while the "Press review to receive setup instructions" message is playing.
The display will change from a segment scanning clockwise to anti-clockwise
4. Quickly press and release the On/Off button before the "Press review to receive setup instructions" ends. The display will change to a square scanning clockwise.
Note, this goes by quickly. I had to repeat steps 1-4 a couple of times before I got it right.
5. Press and release the delete button. The unit will emit a beep.
6. Press and release the on/off button. The unit will emit another beep and annouce "Press review to receive setup instructions"
Done!
