Preparation work
Firstly, please set up the antenna cable and link it to the RFOUT
port in the back of the transmitter. If you need to monitor equipment's
signals, please link to the MONITER output port on the transmitter panel,
the output signal is -50DB. Next, plug the power cable into the mains
of 220V or 380V, and then plug the other end of the cable into the power
socket of the transmitter. Finally, connect the audio cable to the
socket of XLR head. The socket is divided into left and right channels.
After the connection, please turn on the POWER button on the transmitter
panel, and the device will start after 5 seconds.

RF amplifier working voltage
Pa1-Pa6 represents the output ADC
value of the 6 amplification
modules. When the ADC value of any one or more modules is lower than
50% of the highest value of one of the module ADCs, the transmitter will
turn off the RF output and prompt the module alarm page.

3. Alarm information
The transmitter self-safety protection
is activated due to the high return power
of the antenna or cable. The power will
be turned off and please check the
condition of antenna and cable

11
Because the room temperature is too high or
the ventilation system is blocked by too much
dust inside the transmitter, resulting in high
internal temperature and causing overheating
protection of the transmitter.
The power will be turned off and please check
the room temperature to remove dust inside
the transmitter.
The red PA module indicates error,
and the user can repair it by
replacing the new PA module with the
PA module number.
4. Transmitter power module information
Power communication light, normal if blinking
The input voltage indicator of the power supply. There is an input
voltage when it is on, and no input voltage when it is off.

12
Routine maintenance of transmitter
Keep room dry with humidity less than 60%
Maintain a clean dust-free room environment
Keep room temperature below 25℃
Give the transmitter a good ground connection.
Stable power supply system
Do lightning protection measures
Do not direct the air outlet of the air conditioner to the transmitter, especially
the front and rear panels.
Do not block the front and rear panels of the transmitter. The front and rear
panels must have a ventilation distance of 50CM.
