Deregister handsets
If you want to replace a handset or reassign the designated handset number of
a registered handset, you must deregister all the handsets and then individually
register each handset again.
To make deregistration easier, read all of the instructions on this page before
you begin.
Deregister all handsets
To deregister all handsets:
Make sure that all handsets are out of the telephone base
and chargers before you begin deregistration.
Press and hold
/HANDSET LOCATOR on the telephone
base for about 10 seconds. The telephone base
shows Registering handsets.... Please wait for 5 seconds, then it shows
Deregister all devices? Release /HANDSET LOCATOR.
Quickly press /HANDSET LOCATOR again or press YES . You must press
/HANDSET LOCATOR or YES within 5 seconds. If the telephone base
returns to the idle screen, start again with Step 1 above.
The telephone base shows Please wait... and then returns to the idle screen.
All system handsets show Put handset on BASE to register and you hear
a confirmation tone when the deregistration completes. The deregistration
process takes about 10 seconds to complete.
After deregistering, register each handset again individually. See Adding
and registering handsets (optional) on page 100.
NOTES:
If the deregistration process fails, you may need to reset the system and try again. To
reset, unplug the power from the telephone base and plug it back in.
You cannot deregister the handsets if any other system handset is in use.
Even if the battery is depleted, you can still deregister the handsets by following the steps
above.
If in Step 2 above you already have 12 registered handsets, the telephone base
shows Registration slots are full and sounds 2 beeps. Continue holding
/HANDSET LOCATOR until Deregister all devices? displays.
