Handset not registering with base

I followed the instructions on registering the handset with the base. It appears that both are registering because they both display "handset registering" and after a few seconds both handset and base beeps 3 times. However, when I try to make a call on the handset it displays "Invalid. Please register to the base unit".

I've repaired thousands of these kx-tga400b phones and we have the only improved keypad that eliminates the common keypad problems for good.

Does the cordless phone have a 3 in the top right corner after it registers to 3? If so, then it is registering correctly. If it THEN consistently says "invalid, please register" there is definitely a problem with the main circuit board and it's not at all common. I've seen a few of these but it's a rare problem. We can fix it but I'm not sure how much luck you would have with any other repair facilities.

If you have the problem intermittently it's probably a bad RF module. That's a much more common issue.

Then place the handset on the Main Base cradle and follow the instruction that come up on the handset display.if the handset still does not register then most likely the base memory is full and will have to be re-set .

At&T EL52300--one phone reads 'out of range-move closer to base.' I did--it doesn't help. Battery OK---What do I do?
It appears that the one handset has become orphaned and
must be de-registered and then re-registered.

1. To de-register the orphaned handset from the old base:
When the orphaned handset says "Connecting..." or "Out of..."
enter *331734 [menu]
and it will soon beep and display "Not registered"

2. To register the new handset to your base:
press the "Handset Locator" button on the base and hold
it until the "in use" light comes on ( ~ 4 seconds ),
then release the button and set the new handset into
the base phone cradle. After ~ 30 seconds it will beep
and display "Handset #" (next in sequence).

3: Note: the base handles a maximum of 12 handsets.

If your system was fully populated ( ie, a handset is
already # 12 ) you will have to clear all the handsets
from the base and re-register them all in sequence.
( it is the only way to 'rescue' the places occupied
by the lost handsets ).

To clear the base of all registrations:

1. Press and hold the the "Handset Locator" button
until the "in use" light lights and then starts to blink
( ~ 10 seconds ), release the button --
then press it again briefly while the "in use" light
is still blinking.

2. The base will beep and all handsets that were registered
will display "Not Registered"

3. Follow the instructions above for each handset
in turn to re-register them:
press "Handset Locator" ~ 4sec ( in-use light on ),
set handset into the base cradle, etc.

The manual is available from: www.manualslib.com
but does not fully describe these procedures.

Good luck !

E4 - Erros My uniden phone model TRU 9485 - 4WX after outage power, now on LCD screen appear E4 and it didn't respond to any button when i press. I read some help which they say press 3 button...
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.

Registering DSS7905 Accessory Handsets
 Your phone supports a total of ten (10) cordless handsets. Handset(s) supplied in the box with the phone base are
pre-registered at the factory. If you purchase an accessory handset, you need to register the handset before use.
Only one handset can be registered at a time. When charged, pre-registered handsets display a handset ID number.
Handsets that have not been registered display.

Before registering the DSS7905 accessory handset, the battery pack MUST be charged for 15-20 hours.
To register the DSS7905 handset:

Place the handset in the telephone base charging cradle to begin registration.
During the registration process, HANDSET REGISTERING will appear in the LCD. When REGISTRATION
COMPLETE. is displayed; the handset has been registered to the base. If REGISTRATION FAILED. appears,
please try these steps again. When you register an accessory handset to the base, the handset ID will be
assigned.

Note:
If an accessory handset has ever been registered to a base, you must reset the handset before you can
register it to a new base. See Resetting the Handsets on page 24.

My new hand set will not detect my base
Have you followed the instructions for handset registration? For some of the newer handsets, you may need to refer to the instructions that came with the handset (and not the base) instead of just putting the additional handset in the base to register it.

Page 23 of the 9480 manual gives explicit registration instructions.
