Voice Security
Activating Voice Security reduces the chance of your conversation being
inadvertently overheard by a neighbor’s cordless phone or other radio-
receiving equipment within range of your phone.
1 To activate Voice Security, press
s during a call. The display
shows SECURE at the top of the screen. This feature remains
activated from call to call unless you deactivate it.
2 To deactivate Voice Security, press
s during a call, or any time
when you hear dial tone at the handset.
NOTE: Activating this feature may reduce the sound quality of your calls.
Temporary Tone
NOTE: If you have touch tone service, you do not need to use the
Temporary Tone feature.
If you have dial pulse (rotary) service, this feature allows you to enter
codes or tones needed to operate answering machines, or use electronic
banking services, calling cards, and other special services. This feature
will operate most special services; however, some services may actually
require a touch tone line. To be sure, ask the company that provides the
special service.
1 Dial the call, then press t. Any dial buttons pressed after this
send touch-tone signals.
2 After you hang up, the phone automatically returns to dial pulse
(rotary) dialing.
