If there is no signal at all
Check cable connections from the transmitter to the source device, and
the receiver to the receiving device.
Make sure power of all devices are on.
Switch all power off and on again to ensure everything is functioning
1. Connect one end of the BNC cable to the audio and video jacks, and
connect the other end to your source device. (Or BNC-to-RCA adapter to
audio and video jacks first, then connect RCA cable between transmitter
and source device)
2. Connect antenna to transmitter.
3. Connect power adapter to transmitter, then plug in power to an outlet.
4. Turn on power on transmitter.
If the signal is poor, or there is an interference
Change transmitter's location.
Double check if there is a microwave oven in use, and if it is in the path
between transmitter and receiver. If yes, please either remove it or turn
it off.
Make sure the transmission is within its operating range (up to 300
meters with clear line of sight).
1. Connect one end of the BNC cable to the audio and video jacks, and
connect the other end to your receiving device. (Or BNC-to-RCA adapter
to audio and video jacks first, then connect RCA cable between receiver
and receiving devices, such as monitor, speaker....)
2. Connect antenna to receiver.
3. Connect power adapter to receiver, then plug in power to an outlet.
4. Turn on power on receiver.
Pairing Process
Press the "Pairing" button after both transmitter and receiver are power on,
the "Link" light will flash (it means the transmitter is searching the receiver).
The "Link" light become solid when the pairing process is done and
Once the first pairing process is successful, there is no need to repeat it
in the future.
If the "Link" light is off after pairing process is successful, it normally
mean there is no connection between transmitter and receiver. Most of
cases it is because the transmission is out of the range, and the signal
reception is not stable. Please adjust the distance between transmitter
and receiver until it works.
