FAQ
1.No Video Output on the display
1).First check the power supply for TX and RX. Make sure the battery or external power source
functions well if batteries or external power sources are used;
2).Check if TX antennas and RX antennas are installed tightly and correctly;
3).Check the LED video indicator on TX. If it’s not on, make sure the SDI or HDMI cable is
plugged in correctly until the video source information is displayed on the OLED screen;
4).Check if the format of the input video source is compatible with the specifications of this
product;
5).Check if the battery is too low.
2.Poor output video quality
1).Check if the SDI or HDMI input and output cables are plugged in correctly;
2).Make sure the TX and the RX are placed at least 1.5 meters above the ground;
3).Check the "RSSI" status by reading the wireless signal strength indicator. 2-3 RSSI LED lights
should be on for good video quality. If only 1 RSSI LED is on or one of LED lights are on, that
means the received wireless signal is weak. In order to strengthen the signal, the transmission
distance should be decreased and/or another frequency channel should be used to avoid
interference.
