Changing the Digital Security Code

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.

•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.
