To register a handset to a different base, see the section "Expanding Your phone" in the user's guide for the other base.

• Your telephone can accommodate up to four cordless handsets. You can add new handsets (Model E560-2, sold separately) at any time, but each must be registered with the base before use.
• The handset provided with your telephone is automatically registered as Handset 1.
• Additional handsets will be assigned numbers in the order they are registered (2, 3 or 4). You can register a maximum of four handsets.

To de-register all handsets

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.

Did you try this (from the i5801 manual) -

To register a handset to the base, follow these steps:

Step 1: If ENTER BASE ID is displayed on the handset, proceed to the next step; if not, press MENU on the handset, then press ▼ until REGISTER is highlighted; now press OK.

Step 2: Locate the 15-digit Base ID number by pressing, at the base: MENU, then press ▼ until DISPLAY BASE-ID is highlighted, then press OK.

Step 3: Carefully enter this number using the handset dialpad. If you make a mistake, press ‹ to backspace. When finished, press OK.

In a few moments, the handset will be assigned a number (1-6). This will be the lowest available number in the sequence not previously assigned to another system handset.

Step 4: Repeat the procedure for any other unregistered system handsets.

Reply back if you have success. The Base ID is not from the bottom of the base unit, but is something you get by following Step 2 above.

SORRY TO BE REDUNDANT BUT DID YOU HAVE PHONE IN STAND BY AND NEAR BASE.
THEN PRESS PGM
THEN INTERCOM
THE SCREEN SHOULD SAY ENTER SYSTEM ID
ENTER THE 10 DIGITS SYSTEM ID ( THIS NUMBER IS ON A STICKER ON THE BOTTOM OF THE BASE PHONE)
THEN PRESS PGM.
MAKE SURE YOU ARE PUTTING THE CORRECT ID NUMBER IN THE PHONE
I HOPE THIS HELPS

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?

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
