How to Reset a Uniden Cordless Phone Handset
If you own a Uniden cordless phone and you're having trouble getting the phone to recognize its base, you can reset the phone in a few steps. If you bought a series of phones and you want them to be recognized by one base, you can also reset the phone to do so. You can reset your Uniden phone in just a few minutes and bring it back to working order.
Remove the batteries. Turn the phone handset over. Slide open the battery door and remove the batteries from the handset.
Enter the key code combination. Hold down the "#" and "*" keys at the same time, while re-inserting the batteries.
Press the right-side menu button. These are the "soft" buttons which are unlabeled, directly underneath the display screen. The screen should now display "EEPROM CLEAR OK!"
Place the handset on the base. The phone will now register itself to the new base and has been successfully reset.
