While the phone is on-hook and idle, press REDIAL. The display will show the elapsed time of the

The 2750 is equipped with a 2.5mm headset jack, and a built-in headset amplifier, along with a
dedicated HEADSET button. To use this feature, plug a telephone headset with a 2.5 millimeter plug
into the headset jack. There is no need to buy a headset with a separate amplifier. The headset can be
used to make or answer an outside call, an intercom call or a page. Simply press HEADSET instead of
lifting the handset.
To make a headset call on a particular line, press the desired LINE button to connect to that line on the
speakerphone. Then press HEADSET to toggle to the headset. Press HEADSET again to hang up.

This card can be used to record the names or telephone numbers associated with memory locations.

entries.

SPEAKER or HEADSET, or by pressing a LINE button.
Note: The directory is organized alphabetically. To jump to a particular entry, press the corresponding
dial pad number. For example, press the “5” dial pad button three times to jump to the first entry
starting with “L”. You can then use the up and down arrow buttons to view the entries starting at that
point.
6.19 Predialing
Predialing allows the entry of a telephone number on the display before it is dialed out. To make a
predial call, enter the number using the dialpad while the telephone is on-hook. Then lift the handset,
press SPEAKER or HEADSET or press the desired LINE button. Press DELETE to erase digits one
at a time.
6.20 Intercom Calls
Intercom calls may be made by dialing the two-digit station number of the desired station. The speaker
phone automatically activates when an intercom call is placed. See Section 2.6 for a description of
intercom call responses. If the intercom line is busy or the called station is set to DO NOT DISTURB,
you will hear a no action tone.
