Select digital or analog
Your phone can work in both digital and analog modes. The default mode
is digital and analog, which appears on your phone as Digit. & analog
when you press Menu 4-6-7 (Settings > Network services > System
selection).
This means that your phone uses both digital and analog voice channels.
The phone always tries to find a digital voice channel first, but if a digital
voice channel is not available, the phone looks for an analog voice channel.
Note: This feature is available only for certain phones. Contact
your service provider for more information.
• SET TOUCH TONES
Touch tones (or DTMF tones) are sounds that are produced when you press
the keys on your phone’s keypad. You can use touch tones for many
automated over-the-phone services such as checking bank balances and
airline schedules and using your voice mailbox. Touch tones can be sent
only when a call is active.
Warning: If you send touch tones while in the analog mode, be
careful not to send confidential information.
