VT ip8100 - enter base id problem

• 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
• Unplug the power supply from the base unit.
• Remove all handsets from the charge cradles and base.
• Plug in the power supply while pressing and holding the HANDSET LOCATOR button.
• Continue pressing HANDSET LOCATOR until the IN USE and CHARGING indicators are lit (this could take up to 10 seconds).
• Release the HANDSET LOCATOR button.
• All handsets will display: ENTER BASE ID: XXXXXXXXXX
Once the base indicators turn off (up to 30 seconds), the handsets have been de-registered from the base, and can now be re-registered.

To re-register a handset:
• Make sure your handset batteries are properly installed and charged.
• Your handset will display "ENTER BASE ID".
• Enter the 15-digit Base ID number from the bottom of the base unit.
• Press SELECT to accept the new code and complete re-registration.

To re-register a handset to a new base unit:
• Make sure your handset batteries are properly installed and charged.
• Unplug the old base unit. Your handset will display "SEARCHING...".
• Install the new base unit by plugging it into an electrical outlet and phone jack.
• Press and hold the SELECT key until the handset displays "ENTER BASE ID".
• Enter the new 15-digit Base ID number from the bottom of the new base unit.
• Press SELECT to accept the new code and complete re-registration. The handset is now registered to the new base.

It sounds like you are trying to register the handset(s) to the base. Once the handset is charged, if you see 'Searching for Base' on the display,(The bold is for your question specifically but I thought you may like all of the information for getting a phone hooked up) ON the Base unit press MENU, scroll down to Display Base ID, press OK, and the Base ID code will display. If NEW appears in your handset display, press the soft key under it and enter the base ID code you found in the base display. If 'New' does not appear on your handset, press MENU and then scroll down to REGISTER. Press OK and then enter the base ID code. If the handset is already registered, please deregister all then register again. To deregister a handset which is registered to the base model 20-2431, Using the soft keys on the base, press the 'MENU', then press the down arrow once until 'SETUP BASE' is highlighted. Press 'OK'. Press the down arrow 6 times, until 'DEREGISTER ALL' is highlighted. Press 'SET' . If your handset is registered to the base model 20-2481, Using the soft keys on the base, press the 'MENU', then press the down arrow twice until 'SETUP BASE' is highlighted. Press 'OK'. Press the down arrow 7 times, until 'DEREGISTER ALL' is highlighted. Press 'SET'.

Did you try this (from the i5801 manual) -

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.
