choose shield cable as the high frequency signal input
or output cable, so as to improve the anti-jamming
ability of the system.
Attention in the wiring
◆ The equipment shall be connected to the grid power
output socket with protective grounding connection.
◆ Only after cutting down all external power source,
can install, wiring operation begin, or it may cause
electric shock or equipment damage.
◆ This product grounds by the grounding wires. To
avoid electric shocks, grounding wires and the earth
must be linked together. Before the connection of
input or output terminal, please make sure this
product is correctly grounded.
◆ Immediately remove all other things after the
wiring installation. Please cover the terminals of the
products cover before electrification so as to avoid
cause electric shock.
Matters needing attention during operation and
maintenance
◆ Please do not touch terminals in a current state, or it
may cause a shock, incorrect operation.
◆ Please do cleaning and terminal tighten work after
turning off the power supply. These operations can
lead to electric shock in a current state.
◆ Please do the connection or dismantle work of the
communication signal cable, the expansion module
cable or control unit cable after turning off the power
supply, or it may cause damage to the equipment,
incorrect operation.
◆ Please do not dismantle the equipment, avoid
damaging the internal electrical component.
◆ Should be sure to read the manual, fully confirm
the safety, only after that can do program changes,
commissioning, start and stop operation.
◆ Button batteries must be replaced when the power
is off. When you indeed need to replace the button
batteries with the power on, the operation should be
performed by a qualified electrical technician wearing
insulated gloves.
Matters needing attention in discarding product
◆ Electrolytic explosion: the burning of electrolytic
capacitor on circuit boards may lead to explosion.
◆ Please collect and process according to the
classification, do not put into life garbage.

Override
In the Override mode, the delegate unit turns on or off the microphone directly via
the microphone on/off button. When the number of enabled delegate units reaches
the maximum, the unit that turns on the microphone earliest will be automatically
turned off if the next delegate unit turns on the microphone.
Open
In the Open mode, the delegate unit turns on or off the microphone directly via the
microphone on/off button. When the number of enabled delegate units reaches the
maximum, the delegate unit to be turned on next will be added to the waiting list
and enter the waiting state until any enabled unit turns off the microphone.
Voice
In the Voice mode, the delegate unit controls the microphone by intelligently
recognizing the nearest human voice. When the microphone detects the nearest
voice source, it will immediately turn on automatically. When the number of
enabled delegate units reaches the maximum, the unit that turns on the microphone
earliest will be automatically turned off if the next delegate unit turns on the
microphone. (For special requirements, 20 microphones can be turned on freely.)
Apply
In the Apply mode, the delegate unit requests to turn on the microphone through the
microphone button. In the request status, the LED of the conference unit is green.
The chairperson presses the agree button or reject button to decide
whether a delegate unit can turn on the microphone. When the maximum number of
speech delegates is reached, the system allows the same number of delegate units to
enter the waiting list.
