Registration of phone to main phone

Add and register a handset
Each newly purchased handset must be registered to the telephone base before use. When first purchased, each expansion handset shows NOT REGISTERED.
You may need to charge the phone first.
To register a handset:

·Place the unregistered handset in the telephone base or charger. Press Find for 4 seconds. If the headset screen doesn't light up after the 4 seconds. You will need to charge it some more.
·After making sure it is charged set the telephone on the main base again press and hold the Find button for 4 seconds ( until the red light IN USE comes on) Then release the find button. The headset will show PLEASE WAIT; this takes about 10 seconds to complete the registration. The hand set will show HEADSET REGISTERED and the headset number assigned, you will hear a beep when the registration is finished
·When the registration is complete, the newly registered handset is assigned the next available handset registration number. For instance, if you already have HANDSET 1 and HANDSET 2, the next registered handset is HANDSET 3.
·Makes sure no other headsets are in use at the time or the registration may fail.
·You cannot register a handset if any other system handset is in use. Only one handset can be registered at a time.

I had this problem, and I fixed it by re-registering the phone to the base. Here are the directions for how to do that from the manual:


----->

Registering a handset to the
base unit
The supplied handset and base unit are
pre-registered. If for some reason the
handset is not registered to the base
unit, re-register the handset.
1 Handset:
{MENU}
2 {V}/{^}: "Initial setting"
{OK}
3 {V}/{^}: "Registration"
{OK}
4 {V}/{^}: "HS registration"
{OK}
5 Base unit:
- KX-TG4011 series:
Press and hold {LOCATOR} for
about 5 seconds. (No registration
tone)
- KX-TG4021/KX-TG4071 series:
Press and hold {LOCATOR} for

about 5 seconds until the
registration tone sounds.
If all registered handsets start
ringing, press the same button to
stop. Then repeat this step.
The next step must be completed
within 90 seconds.
6 Handset:
Press {OK}, then wait until a long
beep sounds.
Note:
While registering, "Base in
registering mode" is displayed on
all registered handsets.
When you purchase an additional
handset, refer to the additional
handset's installation manual for
registration.

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.

I had the same problem but I fixed it by:

1. Disconnect the battery on the handset.
2. Wait 1 minute and reconnect.
3. Register handset.
