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.

De-Register All Handsets

Unplug the power supply from the base unit

Remove all handsets from the charge cradles and base

Press and hold the PAGE button on the base

Plug in the power supply again while pressing the PAGE button

Continue pressing PAGE until the IN USE and CHARGING indicators are lit. (this could take up to 10 seconds)

Release the PAGE 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 34).
