To make deregistration easier, read all of the instructions on this page before
you begin.

until the IN USE light flashes.
Immediately press /FIND HANDSET again. You must press /FIND HANDSET
2.
while the IN USE light is still flashing. The IN USE light flashes for about
five seconds.
3. The deregistration process takes about 10 seconds to complete. All handsets
alternately show To register HS... and ...see manual.
To register the handset(s) to the telephone base again, follow the registration
instructions on the previous page.
