Replacing a handset

If you are replacing a handset on a system that has the maximum number of registered handsets (4) or wish to change the assigned handset number of your registered handsets, you must first de-register the handsets, then re-register all 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, CHARGING and MESSAGE WAITING indicators are lit. (this could take up to 10 seconds).

•Release the HANDSET LOCATOR button.

•All handsets will display:

ENTER BASE ID

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 (see page 26).
