10. Touch Tones
Your phone can generate various sounds, called Touch
Tones, when the keys are pressed.
Touch Tones can be used for many automated, over-the-
phone services such as checking bank balances, airline
arrival and departure times, and using voice mailbox op-
tions. Touch Tones can be sent only when a call is active.
What is DTMF?
Touch Tones are also known as DTMF, which means
Dual Tone Multi-Frequency, and they are generated either
manually or automatically.
Note: Individual Touch Tones can be sent manually only if
Menu 4 3 is set to 2Q.
