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.
