Appendix A
Replacing a handset
You may need to deregister your handsets if:
You have twelve registered handsets and need to replace a unit.
-OR-
You wish to change the designated handset number of your
registered handsets.
You must first deregister ALL the handsets, and then re-register
each handset you wish to use.
Please read carefully through all the instructions on this page
before beginning the deregistration process.
To deregister all handsets
1. Press and hold HANDSET LOCATOR on the telephone base
for about 10 seconds (until the IN USE light turns on and
starts to flash), then release the HANDSET LOCATOR button.
2. Immediately press and release HANDSET LOCATOR again.
You must press HANDSET LOCATOR while the IN USE light
is still flashing. (The light flashes for about seven seconds. If
the light stops flashing, pick up the handset and place it back
into the telephone base, then start again with step one above.)
3. The handset(s) will show SEARCHING FOR BASE and it will
take about 10 seconds to complete the deregistration process.
ALL handsets will show NOT REGISTERED if deregistration was
successful.
4. To re-register the handset(s) to the telephone base, follow the
registration instructions on page 11.
NOTES:
1. If the deregistration process was not successful, you may need to reset the
system and try again. To reset: pick up the handset and press the HOME/FLASH
button, then press the OFF/CLEAR button and place the handset back into the
telephone base. You may also reset by unplugging the power from the telephone
base and plugging it back in.
2. You cannot deregister the handset(s) if any other system handset is in use.
3. Even if the battery is depleted, you can still deregister the handset by
following the steps above. After the handset is charged for at least 10 minutes,
the screen shows NOT REGISTERED.
