I got button pushing happy on our AXU 4100, and can not longer transmit or receive on our primary channel. While trying to fix the issue, I was able to talk on another channel with another radio, but only that one radio. Is there a way to reset the radio back to default settings, or is there a way to re-program it manually to restore it back. And how do I do this???

Under some circumstances the transceiver’s internal
CPU may cause erroneous indications on the display.
If this happens, reset the CPU as follows:
While pushing [ENT] + , push [POWER] to turn
• The CPU is reset and the display at right appears. CAUTION: Resetting the CPU returns set mode
contents to their default values.
that's the quickest way to do it, hopefully you don't have alot of stored frequecies in memory.
You may have a sub-channel/privacy channel activated. Unless the person/s you are trying to talk to have the same channel and code set they will not be able to hear you. Check your manual for specific instructions on how to reset it to the default.
To troubleshoot: Unlock your keypad lock, then reprogram your radios to the following settings. (Check function after each change)
1) Shut off the Interference Eliminator (set to zero).
2) Turn off the Qt filter.
3) Vox setting to off.
By shutting off all the "bells and whistles" of the radio, you will take it back to being just simply on a frequency. If your radios do not communicate with one another then, or with your friend's radios, you have radio which is failing to operate.
If the radios do work in this simple mode. One by one add the special features back until you discover the culprit.
I have the same walkie talkies and on mine I can hold down the mode/lock button and it will come off of the Rx mode. Also, you should be able to press the talk button and it will come off of the Rx mode.
Re your queries: 1. how to memorize channels? The channels are pre-programmed that a channel number corresponds to a frequency setting. Ex. Ch16 is 156.800 . If for some reasons some channels are missing, perhaps your best course of action is to reset the unit to factory default, that way everything would be back to normal. Master reset is performed by pressing the 16PLUS button while powering the radio. The LCD will display "CL" indicating that the memory has been cleared. If you want to memorize a certain channel/frequency, you can only store it as a replacement for 16PLUS assignment. Ex. Instead of Ch16 as your priority/emergency channel you want say Ch14 (156.700), you can do this by pressing the up/down key till your desired channel; press & hold the 16PLUS key for 3 seconds or until you hear the confirmation beep that your desired channel has been memorized in the memory as the new 16PLUS.
2. Why I cannot transmit? There could be 2 possible reasons: 2.1 You are transmitting on a channel that has been assigned as receive only. Examples are the weather channels, Channels 1,2,3, also 70,75,76, and possibly others. 2.2 Your TX module/circuitry has a problem. More often it is the finals that gets burned.
3. When i use the PTT Channel 16 is automatically set ? The mic has an identical 16PLUS button (similar to the radio's front panel). If you pressed the PTT switch on the side and the radio switches to Ch16 (as if you pressed the 16PLUS button on the front) then you have a wiring problem from the mic to the radio. Possibly a shorted or open connection. It is also possible that you have a break in the small PCB (in some versions) inside the microphone.

Hope this be of some help/idea. Post back how things turns up or should you need further information.
Do you hear the Beeps on the speaker?
Check for the QT and the code squelch are the same in both radios, try to set code squelch in "0".
Make sure that the radio is not receiving or the other one is not transmiting, with two radios will see the same.
I have never seen this problem before, check if the VOX is activated, this could cause to transmit the radio, but the voice must be transmited.
check if the Accesory connector is not dirty, clogged or damaged
