Changing the Digital Security Code
The digital security code is an identication code used to connect the handset and the base. Your unit ships from the
manufacturer with a preset security code. Resetting this code is not normally necessary. In the rare situation that you
suspect another cordless telephone is using the same security code or if you are instructed to change this code by a
manufacturer’s Call Center Representative, you can change the code. To change the digital security code:
Reset all of your handsets.
Register each handset.
To reset the handset:
Press and hold
[ ] and [#] for more than 5 seconds.
Select DEREGISTER HS. Select the handset which you are operating, then press
[select/ ].
The phone will ask you to confirm the deregistration. Select YES. The handset will clear its registration
information from the base, and then delete the link to the base from its own memory.
When the base information is deleted, the handset displays HANDSET NOT REGISTERED-PLACE HANDSET
ON BASE TO REGISTER. SEE YOUR OWNER'S MANUAL FOR HELP.
If the handset cannot contact the base, it will display OUT OF RANGE. Make sure the handset is in range of the
base and the base is connected to power.
To register the handset:
Place the handset in the telephone base charging cradle to begin registration.
During the registration process, HANDSET REGISTERING will appear in the LCD. When REGISTRATION
COMPLETE is displayed, the handset has been registered to the base.
