Using a Headset With Your Telephone
To make and answer a call
using the headset:
1
Press the HEADSET button to acti-
vate the headset.
If you wish to override automatic line
selection, press the desired LINE
button instead of pressing the
HEADSET button, and you will be
connected to that line on the speak-
erphone. Then press the HEADSET
button to toggle to the headset.
2 Press HEADSET again to hang up.
Your SBC-4000 telephone is headset-ready. It
comes equipped with a 2.5mm headset jack, and
a built-in headset amplifier, along with a dedicat-
ed HEADSET button
Simply plug a telephone headset with a 2.5 mil-
limeter plug into the headset jack, and you are all
set. There is no need to buy a headset with a
separate amplifier.
You can use your headset to make or answer an
outside call, an intercom call or a page. Simply
press the HEADSET button instead of lifting the
handset.
During a call, you may switch back and forth
between handset and headset and speaker-
phone as much as you like.
Note that whenever the HEADSET indicator is
on, you may hang up the handset without dis-
connecting your call.
Use the HEADSET button to toggle
the headset on and off.
