The tone length setting enables you to select short or long 

DTMF (dual-tone multi-frequency) tones. When you use a 

teleservice (such as your bank account or voicemail service) 

and press the keys to enter numbers into the teleservice, you 

are sending DTMF tones. The system used by the bank or 

other service determines if you need short or long DTMF 

tones. If the service is digital (which most are these days) 

short DTMF will almost always work. However, some new 

systems and almost all older (analog) systems require you to 

use long DTMF tones. Many home answering machines 

require long DTMF tones.

To set the DTMF tone length:

1.

Press 

 to display the Main Menu.

2.

Press 

 for Setup.

When the desired option displays, press 

 to save the 

setting.

The clock is set and maintained automatically when your 

phone is in digital mode. When you turn on your phone in 

analog mode you must set the time and date for your 

Scheduler and Alarm. Here’s how to set the time and date.

1.

Press 

 to display the Main Menu.

2.

Press 

 for Setup.

3.

Press 

 for Set Time.
