Hello
Connect the phone line and power UP the base unit. Place the handset on base to get charged. It must reset automatically when you place the handset on base to charge. If not; resetting both handset and base unit is necessary.
Resetting the Handset

You may need to reset your handset in the following instances:

You lose a handset and purchase a new one. When you try and register to your existing base you get registration

failure.

You are unable to register any handsets to the base.

You had a base which needed to be exchanged by the manufacturer. When you register your existing handsets

to the base, the handsets say #3 and #4, but you only have 2 handsets.

When you are instructed to by the one of the manufacturer's call center representatives.

To reset, do the following:

Press and hold [ ] and [#] for more than 5 seconds. Select DEREGISTER HS.

WHICH HANDSET? appears. Select the handset that you want to de-register, and press the OK soft key.

DEREGISTER HS appears. Select YES, and press the OK soft key.

ARE YOU SURE? appears. Select YES, and press the OK soft key. You will hear a confirmation tone. The

handset will clear its registration information from the base, and then delete its own base information.

MODELS VARY! PLACE HANDSET ON THE BASE FOR REGISTRATION OR REFER TO OWNER'S MANUAL. To

re-register the handset to the base (see page 25).

If the handset cannot contact the base, it will display OUT OF RANGE. Make sure the handset is in range of the

base and the base is connected to power.

Note: It is also possible to reset the handset back to its original factory settings. All changes including Caller ID information

will be erased. For more information on resetting the handset back to factory settings and when you need to

do this, see www.uniden.com or call our Customer Service Hotline. See back cover page for contact information.

Resetting the Handset without the Base

If your original base is not available for some reason (for example, it is lost or somehow incapacitated), you can still

reset the handset and use it with another base.

Press and hold [ ] and [#] for more than 5 seconds.

Move the cursor to select BASE UNAVAILABLE and then press the OK soft key.

BASE UNAVAILABLE appears.

Move the cursor to select YES, and then press the OK soft key. ARE YOU SURE?

appears.

Move the cursor to select YES, and then press the OK soft key. You will hear a confirmation tone. The handset

will delete its own base information without trying to contact the base. When the base information is deleted,

the handset displays MODELS VARY! PLACE HANDSET ON THE BASE FOR REGISTRATION OR REFER
TO OWNER'S MANUAL. Register the handset to the new base (see page 25). of its user manaul.
OK.

The Uniden XDECT7055 Owner's Manual is unclear regarding setting up the day/time. When I go to the MENU/SELECT function and scroll down, the date/time is not one of the functions offers to set. The only...


Phoned Uniden - durrgggh - had the same problem - simple solution - advised them to improve the manual - is totally not clear!!!!
As below:
  • Day and time must be set in 12hr times - not 24 hrs
  • Must be set from a handset - any handset that is registerd to the base is fine
  • Follow handset instructions but make sure hours are set as 01 - press menu / select to confirm
  • Then place the handset back on its base - all other handsets and the BASE will then change to that day / time
Hope this helps

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

Two sets Uniden phones with base, second handset: incompatible?


I had the same problem with a Uniden 3355 handset and 2355 base. With the new handset I pressed "Menu" and selected "System Reset". I then Selected "Deregister HS" and followed the prompts.
Once this was complete, I returned to "System Reset" and selected "Replacing Base". Following the prompts, when it said "Register Handset" I put it in the base of the 2355, and within a minute it had registered, so both handsets used the base of the 2355!

Resetting the Handset


YOU might need to deregister the hand set first by holding down the red end (hang up key) and keep it down while holding the # key. If deregister wont work use base unavailable and yes, you are sure twice.

List the handset numbers of those working handsets
Using a WORKING handset follow these directions
Resetting Handsets
If you want to register the handset to a different base or
replace a handset with another one, you must first clear the
registration information from the base and the handset.
1. Press and hold [ ] and [#] for
at least 5 seconds, until the
SYSTEM RESET menu
appears.
2. Select the DEREGISTER HS
submenu. WHICH HANDSET?
appears in the display.
3. Move the cursor to select the handset ID to be de-registered
from the list, and then press the OK soft key. DEREGISTER HS
appears. CHOSE A NUMBER THAT IS NOT ONE OF YOUR WORKING HANDSETS
4. Move the cursor to select YES, and then press the OK soft key.
When ARE YOU SURE? appears, select YES. You will hear a
confirmation tone.
PUT THE HANDSET IN THE BASE CHARGER AND IT SHOULD REGISTER

Hope This Helps - It worked for me
