3.4.4.2 Chairman unit
The chairman unit features all the functions of a
delegate unit, and the following additional functions:
1. Priority
If the priority mode on the main unit is configured
as “All mute”, all active delegate and VIP
microphones will be muted temporarily when this
key is pressed and they will restore when this key
is released;
If configured as “All off”, all active delegate
microphones will be turned off and the
request-to-speak list will be purged when this key
is pressed. All active VIP microphones will be
muted temporarily when this key is pressed. They
will restore when this key is released.
2. Speaking
If the number of active microphones in the system
is less than 6 (including chairman /delegate /VIP
unit), the chairman can activate his/her
microphone normally, the operation is the same as
for the delegate unit (refer to section 3.4.4.1).
If the number of active microphones in the system
is 6, the chairman cannot activate his/her
microphone. But he/she can use the “Priority” key
to “All mute” or “All off” other microphones and give
his/her speech.
Without connecting to PC, under “OPEN/
OVERRIDE/ Apply” mode, the chairman unit can
be set as DAIS status, in which the microphone of
the chairman unit with control function remains
active during the meeting.
3. Controlling delegate unit
A. Approve delegate unit’s request to speak
Under “Apply” mode, when a delegate requests to
speak, a ring tone will be emitted by the built-in
loudspeaker in the chairman’s unit (ring mode has
been configured as “ON”). The chairman can approve
delegate’s request and activate delegate’s microphone
by pressing the microphone on/off key or reject
delegate’s request by pressing the priority key. Only
one delegate can request to speak at one time and a
ring tone will also be emitted by the built-in
loudspeaker.
B. Turn off or mute delegate microphone
The chairman can use the “Priority” key to execute “All
mute” or “All off” operation.
