To be able to register your replacement handset, you must de-register all the handsets from the VT2656 base unit.

Follow the steps below to de-register your handset(s) from the VT2656 base:

1. Take out the handset that sits on the base.
2. Unplug power from the base.
3. Hold down PAGE while reconnecting power. When the In Use light blinks, release the PAGE key.
4. Hold down PAGE key for 5 seconds. When the In Use light begins to flash, release the PAGE key.
5. The handset charging light will blink 5 times. Within 5 seconds from when it stops blinking, press PAGE once.

You must register the handset(s) by following the steps below:

1. After charging the handset, remove it from the cradle, the LCD display will read "SEARCHING FOR BASE".
2. Press "NEW" and then enter the 15-digit Base ID code, located on the underside of the VT2656 base unit.
3. Press "OK". The handset will display "PLEASE WAIT!!".
4. Wait approximately 15 seconds. The handset will display "FOUND BASE". If the handset displays "BASE BUSY TRY LATER", this indicates that the system is in use. Wait until the base unit is in the idle (on hook) mode and repeat steps 2-4.

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.

The "END" and "#" key combination can be used for several purposes:

1) If wanting to use an ALREADY REGISTERED HANDSET on an alternate base, and if if the INITIAL BASE isn't available to deregister the handset:

1a) Press "END" + "#" until it for 5+ seconds (wait for it to beep)
1b) Choose the "Base Unavailable" option
1c) That'll deregister the CURRENT HANDSET so that it can be re-registered on ANY base.

2) If a BASE has a handset registered to it which you no longer want registered but the registered handset is missing or broken:

2a) Grab another WORKING handset which is properly REGISTERED to the BASE in question
2b) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)
2c) Choose the "Deregister HS" menu option
2d) Pick the REGISTERED HANDSET # to de-register. (Every other registered handset EXCEPT THE ONE YOU'RE ON will appear in the list!)

The handset/base keeps a record of who it’s registered to. The base also keeps a record of how many handsets are registered to it.

Using the de-register function on the handset deletes the handset from the base (decrements the count) and deletes the base info from the handset. All this requires that the base and handset can communicate with each other.

To remove the base data from a handset when out of range of the base, press and hold the ‘end’ button and the ‘#’ button simultaneously until the phone beeps. It will now be de-registered from the base.

However, the base will still have this handset in it’s record.

To de-register all handsets from the base, remove power and the base handset. Press and hold the ‘flash/find hs’ button while applying power. Wait for the beep and release the button. The charge light will now flash. Sit any handset in the cradle. When the flashing stops, all handsets are inhibited from connecting.

However, the handset still appears to be connected to the base unit. Pressing talk will give an ‘Unable to connect’ message. To re-register the handsets to the base, you have to de-register the handset first with the two button method.

Of interest, pressing ‘*’ and ‘#’ on the handset while reconnecting the battery is suppose to reset the handset. Doing the same on the base unit puts you in some sort of diagnostic mode. Press speaker to exit.
