Changing from Tone to Pulse Dialing
Phones can communicate with the telephone network in two ways:
tone (DTMF) or pulse dialing. If you know your phone company uses
pulse dialing or the test call for line 1 did not work, follow these steps:
With the phone in standby, press MeNu .
Use up or DowN to highlight Global Setup, then press ok .
When your phone prompts you to select a line, press LINe1 .
Use up or DowN to highlight Dial Mode, then press ok .
Highlight Pulse, then press ok . The phone sounds a confirmation
tone. Try making another test call using line 1.
If your test call on line 2 did not connect, follow the same
process, but press LINe2 in step 3.
If you use pulse dialing and you need to send DTMF tones during a
call (if you're using an automated response system, for example),
press to temporarily switch to tone dialing. When the call ends, the
phone automatically returns to pulse dialing mode.
