Precautions for Lithium Battery Use
In case of the following abnormality during use, turn off the power switch, take out the
battery, and keep the equipment away from fire; if not, there is a risk of fire or explosion.
——The battery is leaking, changing color, deformed, or damaged.
——The battery is smoking or smelly.
Do not weld or modify the battery or change its form; otherwise, the battery circuit may
be damaged, resulting in a fire, leakage, even explosion.
Avoid the battery shorting (anode and cathode) by electric wire or metal and do not place
the battery and metal(e.g. chain or key) together for storage or transportation; otherwise,
the battery may be heated up, resulting in leakage, fire or explosion.
Do not heat the battery or throw the battery into fire; otherwise, the safety valve or
protective circuit of the battery may be damaged, resulting in fire or explosion.
Do not set the battery in water or moisten the battery anode/cathode; otherwise, the
battery will be corroded and heated up, resulting in, leakage, fire, or explosion.
Use specified charger to charge the equipment. Avoid reversing the battery anode and
cathode; otherwise, the battery may be heated up, resulting in leakage, fire or
explosion.
Do not place the battery near fire or expose the battery to high-temperature environment
(60°C; e.g. in car); otherwise, the battery circuit may be damaged and heated up,
resulting in fire, leakage, even explosion.
The battery must be used on specified equipment model; if not, the battery may be
heated up, resulting in leakage, fire or explosion.
Do not drop or vibrate the battery; otherwise, the battery circuit may be damaged and
heated up, resulting in a fire, leakage, even explosion.
In case the battery leakage enters eye, use clean water to flush the eye and seek
medical care immediately; if not, blurred vision may occur.
In case the battery leakage stains clothes or skin, use clean water to flush it; if not, skin
may be damaged.
Battery capacity will be too low if the lithium batteries are left unused for a long
time, which will damage the batteries. Remove the batteries and make sure they
are fully charged every three months.

2.4.2 Connection with Wireless conference access points
extend cascading
When the server is connected to the wireless conference access point, pay attention to the
required coverage of the conference venue. If the area to be covered by the conference venue

13
is too large or the maximum number of speakers needs to be increased, extensible cascaded
WAP can be used.The following figure shows the wiring diagram:
2.4.3 Connection with Wireless AP and Control PC
The successful communication between the congress server and a wireless terminal
must be supported by a wireless AP WAP-30C to perform signal conversion. The
conference server has 4 RJ-45 connectors, any one of which can be connected to the
control computer. The following figure shows the wiring diagram:
2.4.4 Connection with Mixer or Amplifier

RCA connector unbalanced audio output (LINE OUT), and one balanced audio output
(CANON). Connected to the sound amplification system, the speaker's voice can be
amplified and output.The connection only needs to use an RCA unbalanced audio
output "Line OUT" or a balanced audio output "Canon" to connect to the audio output
interface of the server, and the other end is connected to the input end of the sound
amplification system. The following figure shows the wiring diagram:

2.4.5 Connection with Camera
Among the three groups of wiring from the camera (for details on camera operation, refer to
the camera operation guide), two groups of wiring are used for connecting to the congress
server (power of the camera is supplied directly from the control room). One group is the HD
video wiring, which is implemented by connecting the video output of the dome camera to
the SDIINPUT of the HD matrix over an BNC connector; where, number 1–input 1; number
2–input 2. The panoramic preset position and the video tracking of the chairman terminal are
completed by number 1 camera. The other group is the RS-485 wiring. Generally, use
network cables for communication and select a pair of wires as the “+” and “－” of the RS-
485 cable. Refer to the following figure:
GONSIN30000S use 8I+8O HD matrix with the SDIOUTPUT, which is BNC connector.
Connect the matrix to a display device (such as monitor or converter) using an HD video cable.
Refer to the following figure:

15
Note: Please refer to the software instructions for setting the camera tracking Settings.
2.4.6 Connection with the Dome Controller
Make sure that the GX-KB01 dome controller ’s protocol and baud rate are already
preset (please see dome controller user manual for the settings). Use a 2-pin twisted
pair cable to connect 485+ and 485- of dome controller to 485+ and 485- of central
control unit. Please note that the RS485 control cable of dome camera is already
connected with RS485 control cable of central control unit.
The control cable of dome controller can also be connected to control cable of dome
camera.
