2.11.4  Headset Operation
Description
This PBX allows the use of headset-compatible PTs. A PT user can talk to another party without lifting the
handset. This feature is also known as Handset/Headset Selection.
For connection and operation, refer to the Operating Instructions for the headset.
Conditions
• Hardware Requirement: An optional headset
• If headset mode is on, pressing the SP-PHONE button activates the headset, not the built-in speaker.
• To set headset mode on a DPT or IP-PT, use personal programming (Headset Operation) or press the
Headset button. To set headset mode on an APT, use the handset/headset selector provided on the set
and/or on the headset.
• Headset Button
A flexible button on a DPT or IP-PT can be customised as a Headset button. It is possible to assign a
Headset button to a flexible button on an APT, but the button will not function.
• Answer/Release Button
A flexible button can be customised as an Answer button or a Release button. Such buttons are useful for
headset operation. It is possible to answer an incoming call by pressing an Answer button. While hearing
the Call Waiting tone during a conversation, pressing an Answer button enables one to answer the second
call by placing the current call on hold. Pressing a Release button enables one to disconnect the line during
or after conversation, or to complete a Call Transfer.
• It is possible to switch from headset mode to hands-free mode or vice versa during a conversation by
pressing the Headset button.
• Headset users cannot use the following features:
– Automatic Redial (® 2.6.3  Last Number Redial)
– Receiving OHCA
– Receiving Whisper OHCA (® 2.10.4.4  Whisper OHCA)
