3.1 Getting A Dial Tone
Your telephone may be configured to provide an intercom dial tone when
the handset is lifted. This arrangement is known as “prime intercom.” It
may, however, be arranged to provide outside line dial tone instead. This
arrangement is known as “prime line automatic” or “idle line
preference.” This means that you can dial the system feature codes as
soon as you lift the handset. If your telephone is arranged otherwise, you
must obtain intercom dial tone before you can dial the various feature
codes. You do this by pressing the INTERCOM button after you hear
the outside line dial tone.
3.2 Making A Call

arranged for prime intercom),
1. Lift handset and listen for intercom dial tone.
