68 CHAPTER 5: PERSONALIZING YOUR TELEPHONE
To prepare a headset so that you can choose either the handset or the
headset for each call:
1 Insert the cord for the headset amplifier into the handset cord receptacle
on the underside of the telephone.
2 Insert both the headset cord and the handset cord into the headset
amplifier.
3 For headset calls: Lift the handset off the telephone and leave it off. Use
the headset microphone and earphones.

the handset from the cradle to use the headset.
4 For handset calls: Press the button on the headset amplifier that turns
the headset off, pick up the handset, and speak into it.
To manage calls when you are using the headset:
1 Put the headset on. When a call comes in:
■ If the handset is on hook, pick it up, set it on your desk, and begin to
speak.
2 To end a call when you are using a headset:
■ On a 3Com Entry Telephone or an analog telephone, hang up the
handset or press Feature + 111.

power-saving mode to the active mode when calls first come in, so your
telephone may not ring until the headset has returned to active mode,
and you may miss a call.
If you plan to not use the headset for a long time (for instance,
overnight), 3Com recommends that you set the mute and headset
