The tone length setting enables you to select short or long
DTMF (dual-tone multi-frequency) tones. DTMF tones are what
is sent by your phone to access tele-services (such as a bank
account). The system used by the bank or other service
determines if you need short or long DTMF. If the service is
digital (which most are these days) short DTMF tones will
almost always work. However, some new systems and almost all
older (analog) systems require you to use long DTMF tones.
To set tone length:
1. Press to display the Main Menu.
2. Press for Sounds.
3. Press for Tone Length.
4. Press the scroll keys to toggle between Short and Long.
5. When the desired option displays, press to save the
setting.
