FAQ
1. Check and make sure that the power supply works fine on both the transmitter
and the receiver.
2. If the device displays with the low-battery sign, change or charge the battery in
time.
3. Try to change to another channel and to connect the devices again for there
might be interference for the current channel.
4. Re-pair the devices.
5. Check if the antennas on the transmitter and receiver are correctly installed.
1. Check if the video source is connected to the HDMI IN or SDI IN interface
correctly.
2. Check if the OLED displays the video format. If not, check if the HDMI/SDI cable
connected to transmitter is correctly linked with the camera and if the camera

DISPLAY ISSUES

FAQ
1. Set “SCENE MODE” to “IMAGE MODE”.
2. Check if the HDMI/SDI IN or OUT cables are correctly connected.
3. Make sure both the transmitter and the receiver are installed at least 1.5m
above the ground.
4. Check the signal strength status. If it is with only 1 bar signal, it means that the
signal strength is very weak. In this case, change the channel or shorten the
distance between the devices.
1. Check the number of connected APP devices. When 1 transmitter is connected
with only 1 or none receiver, the system can still connect up to 4 App monitoring
devices; or 1 transmitter can connect with maximum 2 receivers and no APP
monitoring device.
