Hands-free mode (HFM)

Hands-free mode enables the use of the hands-free microphone on your communication device for a call,
rather than using a handset.
In hands-free mode, audio is received through the hands-free speaker, and transmitted through the
hands-free microphone. Switching to hands-free mode does not free up the handset voice channel; the
channel is in use for the duration of the call.
The hands-free speaker is a separate voice channel from the speaker channels; however, the microphone
is used for the Push-to-Talk function on speaker calls as well as for hands-free calls. While you are in a
hands-free line or intercom call, as long as you press the Push-to-Talk button for an active speaker
channel, the microphone connects to that speaker channel. The hands-free call is not dropped, but the
distant end cannot hear the speaker channel conversation. When you release Push-to-Talk, the hands-free
call resumes.
The IQ/MAX TOUCH turret has a full-duplex hands-free speaker and microphone on the Primary
Module.
Hands-free mode can be used in the following scenarios:
•
Intercom calls: When auto-answer intercom is enabled at the communication device, intercom calls
use hands-free mode.
•
Line calls: Line calls are always initiated and answered on the handset. To use hands-free mode,
make or answer the call first, then switch to hands-free mode.
•
Replay function: The hands-free speaker is used to play recorded audio using the Replay function in
the Speakers application.
While a call is active, you can switch between a handset or headset and hands-free mode, provided the
hands-free speaker is on.
While in a hands-free call, you can adjust the transmit volume. You can also mute the microphone so the
distant end cannot hear you. The mute setting applies to both the handset and the microphone, and the
setting is preserved if switching from one mode to the other. The handset hardware does not mute the
microphone in a hands-free call.
Note
Muting only affects the microphone while it is used in a hands-free line or intercom call. Muting does not
affect the microphone while it supports Push-to-Talk on a speaker call.
While in a hands-free line call, you can swap the call between handsets if the other handset is idle.
8.11.1.1 Use hands-free mode (HFM)
Hands-free mode is available for all handset calls. You can activate hands-free mode before or during an
intercom call. You can switch to hands-free mode after making a line call. You can also adjust the
volume of the hands-free speaker and mute the microphone in hands-free mode.
