Dtmf Tones - Nokia 3155 User Manual

DTMF tones

DTMF tones are the tones that sound when you press the keys on your device
keypad. You can use DTMF tones for many automated dial-up services such as
banking and airlines or for entering your voice mailbox number and password.
DTMF tones are sent during an active call. You can send them manually from your
device keypad, or send them automatically by saving them in your device.
To set the type of DTMF tones, select in standby mode Menu > Settings > Phone >
DTMF tones > Manual DTMF tones and one of the following options:
Continuous — Used to set the tone sound for as long as you press and hold a key.
Fixed — Used to send tones of the duration you specify in the DTMF tone length
option.
Off — Used to turn off tones. No tones are sent when you press a key.
You can specify DTMF tone length for the Fixed option. In standby mode, select
Menu > Settings > Phone > DTMF tones > DTMF tone length > Short (0.1 seconds)
or Long (0.5 seconds).
Start-up tone
You can select to have a start-up tone when you first turn on your device.
