SOURCE: ADDING HANDSET SAYS OUT OF RANGE

A search of Uniden support only said to call 1-800-297-1023 with handset registration issues. The rep picked up quickly and walked me through the reset procedure. Here it is step-by-step:

1. Remove battery
2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it's workable)
3. Screen will be blank. Immediately press the right soft menu button.
4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok
5. Remove battery (yes again)
6. Reinsert battery (this time there's no need to hold down any buttons)
7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)
8. Place handset on base and it will register as normal

This is not a direct solution to your problem, but a workaround for a similar situation. I have two headsets and two charging stations. One of the headsets was stuck with the message ''Welcome! please wait''. When I put the phone on the charging station it usually sits on nothing would happen, but when I put it on the other station the phone came back to life. The non-working charging station will still charge the phone so it is worth keeping.
