Registering a handset will not register. It will not let me go through the menu to de-register it either.

Is the handset you are trying to register de-registered? if not it will not register to another base until it is.first de-registered.
To de-register the handset do the following-
With a charged battery in the handset Enter *331734# then without pause Press and Release the Menu Select Button. You will hear a Beep. Handset would then be De-registered..
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 .
To re-reset the Base:- Remove any handset from the main base cradle. Then Press and Hold the Locator or find HS or handset Locator button until the IN USE light comes on and begin to flash then release it and immediately with out pause press and release it again. That will re-set the base memory. All your handset will then be de-registered and will to be re-registered. Place each handset to be re-registered on the Main Base cradle and follow the instructions on the the handset display and they will register.

You might try to de-register the handset and re-register
it to the base. Be sure the handset's battery is well
charged, a weak battery can impede the registration.

The handset must be de-registered before it can be registered.
Try this:

1. To de-register the handset from another base:
When the orphaned handset says "Connecting..." or
"Out of Range..."
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 !

In the instructions you need to find how you Sync the base and add that number phone to the base. All have different ways so try the company website on google.

Called the manufactuer.... To do this enter on the handset you want to deregister:

*331734# and press (Menu Key# 1 - top uppermost left button that is unmarked).


This will put the handset back into the register mode.



Hope this helps,

*331734#Menu Select on the handset should de-register that handset from the old base, then you can register it to the base as per the manual (put it in the base and hold down the handset locator button for 4 seconds)

not sure if you have already got a solution for this problem as it was also listed in the Premium section until a few hours ago.

You must ensure each handset is charged for atleast 20 hours.

Best to de-register each handset first. Follow the menu on base or handset to select de-register.

Then follow the registration process for each handset using the menu function.

Hope it works this time.

To de-register HANDSET #1:

1) Grab any working handset which is registered to your base (so HANDSET #2 or #3 in your case)

2) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)

3) Choose the "Deregister HS" menu option

4) Pick HANDSET #1 as the handset ot de-register (since that's the "phantom" registered handset)

5) Once de-registered, you can de-register handsets #2 and #3 directly from each handset's "normal" menu interface (i.e. press "Menu", choose "Deregistration")

6) Thereafter, if you re-register your handset, they should start at HANDSET #1, then #2, and so on.

If you are still looking for an answer on dereg of a handset, the manual says Menu - 0-0-2 then 3-3-5-OK then select the handset you want to cancel/deregister
