Before a meeting starts, the conference units need to
be configured by the operator, including: numbering
and testing. During the meeting, the participators use
the conference unit to activate microphone, request to
speak, etc.

3.4.4.1 Delegate units
1. Number
First of all, make sure that the conference units are
connected properly to the CMU. All conference units
must be numbered when the system is used for the first
time or when adding or replacing conference units. The
numbering function can be activated by menu
operation on the CMU front panel or by application
software.
After selecting “Numbering” with the “MENU” key, two
options “All” and “Append” will be shown on the LCD of
the CMU.
When the system is first in use, “All” should be selected.
Press “MENU” to confirm and a “Numbering” prompt
will be shown on the LCD. When “Numbering” is shown
on the LCD, all the LED indicators on the contribution
units connected will blink. Now press the “Mic ON/Off”
key on the contribution units one by one to number
each unit. The number starts from “1” and the next
number is increased by 1. When numbering, number
the contribution unit one by one in a certain order,
make sure not to press more than 1 contribution unit at
a time, otherwise repeated numbers may arise and
complicate the management of the conference. When
finished, press the “EXIT” key to select “End”
numbering. The CMU will automatically test each line
and read the number data. Now the CMU needs to
restart.
In case the number of contribution units is increased or
some unit is replaced, the increased or replaced unit
can be connected directly into the current system and
there is no need to restart the CMU. Press “MENU” to
select “Append”, and then choose “Add from number of
maximum”; at this moment, all the indicators on the
contribution units connected will blink, just press the
“Mic ON/Off” key of the added/replaced units to number
them. Those units numbered previously do not need
numbering again. After numbering, press “EXIT” to
finish, the CMU will test the lines automatically and
read the data.
Speaking mode is configured on the CMU. (refer to
section 2.1.4)
