It requires the radio programming program. You must take it to a dealer. It will cost a bit to be reprogrammed, call in advance.

Long press P3 and check key sign will be goes OFF, now your keypad is unlock.

• HI, I can help.

• This is a radio that can only be programmed with the use of a computer interface. The problem is that this unit has been discontinued. http://dogbytecomputer.com/motorola-axu4100-4-watt-uhf-programmable-radio.html there is a radio out that has "replaced" this on if you will http://dogbytecomputer.com/motorola-rdu4100-uhf-4-watt-10-channel-on-site-two-way-radio.html both of those radios program the same way. However to reset that radio to default or add any frequencies there is no way to do that without the interface.

• You will have to contact an authorized Motorola dealer such as http://www.buytwowayradios.com/products/motorola/motorola-ax-axu4100.aspx or any reputable two way radio store in your area. Those radios are still very programmable. I wish there was some way around this but there is not and Motorola gets very grumpy when unauthorized people end up with their interface because it is in fact quite the money making racket.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Channel 4 should be 462.6375 MHz, and code 4 should be 77.0 MHz.
