Question about Uniden TRU9480 Cordless Phone

Open Question

Uniden TRU9480-3 died with a E4 on the base. Replaced with a TRU9485-3 and all the handsets the came with the 9485 work (after a base reset and reregister) but I cannot get the handsets from the 9480 to register with the 9485 base. Even did a EEPROM reset and still they just show Unavailable and Registration Failed. Any ideas?

SOURCE: How to REregister handsets

You can unregister your phone without being in the cradle, but to re-register them, just put them back in the cradle.  After being unregistered, they will automatically re-register once they are put back in the cradle of the main base.  Try setting them back in the base cradle to re-register, and hopefully that will work for you.

SOURCE: E4 trouble condition comes up on screen after power up

Error #4, You probably need to reset the phone by unplugging the main unit from the power source then plugging it back in abd re registering the handsets by setting them in the main cradle for about 10 seconds each. if this doesn't work try the manual if you have it still and see what E4 error means. Good Luck. Sometimes with electronics all you need to do when they wont work is unplug then and plug them back in while holding the power button on. This is amazing trick that no one wants anyone to know about. it works great on VCR's and DVD players.

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.
