The transmitter and receiver are unable to establish a connection

1. Examine whether all the antennas are being fan shape.

2. Examine whether the power adapter or battery input meets the product’s specification requirements.

3. Examine the product whether it can be started up normally; whether the screen can display normally.

4. Examine whether the system channels are corresponding.

A black screen is displayed on the monitor via receiver output

Suppose the monitor displays a black screen through receiver output after switching the video source’s video resolution. Please unplug and plug the transmitter or receiver’s HDMI cable. If unplugging and plugging an HDMI cable does not make the system work normally, please restart the transmitter and receiver.

The monitor displays mosaic or lag
  1. Switch all the working channels to check, then select stable one to connect.
  2. When multiple systems are used simultaneously, please ensure that the transmitters are at least 1 meter apart, the receivers at least 2 meters apart.
  3. The transmitter is set up on a camera, it should be set up at 1.5-2 meters above the ground, and the cameraman’s body should not obstruct the antennas. The receiver should be set up at least 2 meters above the ground, and the antennas are fan-shaped, and each has a clear line of sight.
  4. If multiple systems are used simultaneously, they must be set to different channels and it is recommended to keep them at least one channel apart.
  5. If a wireless broadcasting and communication system is used on set, please keep the broadcast and communication host and the CVW receiver at least 2 meters apart.
No video output when connecting a receiver to a switch console or monitor

1. Examine whether the power adapter or battery input meets the product’s specification requirements.

2. Examine whether the transmitter and receiver have successfully established a network connection. Can examine this by viewing the signal strength icon on the display screen.



The display is flickering green when the receiver outputs video signal to the monitor

The HDMI cable has not been firmly plugged in the transmitter or receiver’s HDMI port or has not been firmly plugged in the camera’s HDMI port. Please unplug and plug the HDMI cable or change it to another HDMI cable.

The channel setting when you using one or more systems

1. Whenone system is in use, it is recommended to set the channel at CH5-CH9. Because in most Wi-Fi coverage environments, the high and low frequency is mostly used, while somewhere between is rarely. The middle frequencies have low occupancy rates, which effectively avoids co-channel interference. Once the channel scanning function is enabled, it could quickly help to select the best possible channel from the available channel list.

2.When two systems are used simultaneously, the receivers must be placed at least 1 meter. Once the 80MHz operating mode is enabled, system one is set at CH5, and system two must be set at CH7, CH8, or CH9. It is recommended to keep them at least one channel apart. Once the channel scanning function is enabled, it could quickly help to select the best possible channel from the available channel list.

3.When multiple systems are used simultaneously, the receivers must be placed at least 1 meter apart. Once the 80MHz operating mode is enabled, system one is set at CH5, system two is set at CH7, and system three is at CH9. It is recommended to keep them at least one channel apart. Once the channel scanning function is enabled, it could quickly help to select the best possible channel from the available channel list.

The corresponding bandwidth to its working frequency

5.1-5.9GHZ (CH1-5.19G, CH2-5.23G, CH3-5.27G, CH4-5.31G, CH5-5.51G, CH6-5.55G, CH7-5.59G, CH8-5.63G, CH9-5.67G, CH10-5.755G, CH11-5.795G).

Two ways for HDMI, SDI and LAN port outputing

It could not only supports HDMI or SDI or LAN port to output separetly, but also supports HDMI, SDI and LAN port to output simultaneously. The output is including the video and audio.

Extend the transmission range

You can use CVW panel antenna to extend its transmission range.  A panel antenna is a type of directional antenna, which can be used to extend the system’s transmission range, but the trade-off is that the panel antenna has a transmission angle of 45 degrees.

Does the PRO800 plus TALLY function support one transmitter to multiple receivers?

The TALLY function used the 2.4G band, so it only supports one to one transmission, not one-to-multiple.

PRO800 plus has no sound output

1. Check whether the microphone and headphone jack are connected correctly.

2. Check whether the transmitter and receiver power startup is normal or not. After the system is powered on, the OLED screen or power indicator will be on, and you will hear a sound from the headset.

3. Check whether there are multiple systems are used on set(voice intercom transmission only supports one to one). If the systems can’t be paired with each other, long press the hole 3 seconds, what close to the MIC interface, then restart the machine to enter the automatic pairing status.

Does the voice intercom only support mono?

The product is designed for mono to avoid dual-channel reception and not to interferece by the surrounding voice. If the voice is lower, you can adjust the volume of the headset to control the volume output.
