ADDITIONAL INFORMATION[ 40 ]
The digital security code is an identification code used to connect the handset and the
base unit. Normally, setting the code is not necessary. The first time you charge your
handset, the security code is automatically set. (See About the digital security code,
page 8.) In the rare situation that you suspect another cordless telephone is using the
same security code, you can change the code. To change the digital security code,
deregister the code, then register a different code.
Deregister the Digital Security Code
1) Remove the handset from the base. In the standby mode, press and hold
xfer/del and end for 10 seconds. You will hear a confirmation tone.
De-Register? appears.
2) Press
+ to select Yes, then select/ch. You will hear a confirmation tone, and
Deregistration Complete appears.
Changing the Digital Security Code
If you have not pressed any key for 30 seconds while in the deregistering operation, the phone
returns to the standby mode.
While in the deregistering operation, if you receive an incoming call, page, or transferring call, or
charge the handset, or press
talk/flash or end, the operation is canceled and the phone will
return to the standby mode.
