4.1Dialing Pause

In some cases, it is desirable to have the phone pause when outputting digits. For example, a call to an IVR system that requires a password should wait until the system answers before dialing the password.

To insert a pause press the HOLD key while pre-dialing. Each press of the HOLD key will insert a 2 second pause and will show on the screen as “- -“. For example, if the LCD shows 123 -- -- 45, the phone will output 123, wait 4 seconds and then output 45.
