| **No Image(Black Screen)**      | <ol><li>Please confirm whether video source is well connected to HDMI output connector of receiver;</li><li>Please confirm whether receiver is powered on normally;</li><li>Please confirm whether monitor is working properly;</li></ol>                                                                                                                                                                                        |
| **Shown "Searching TX"**        | <ol><li>Please check whether transmitter is powered on normally;</li><li>The signal is weak at receiver side. It's recommended to reduce the transmission distance appropriately;</li><li>Please power off and reboot or re-pair;</li></ol>                                                                                                                                                                                      |
| **Shown "No Signal Input"**     | <ol><li>Please check whether the signal source of HDMI is normal;</li><li>Please confirm whether the output resolution of the signal source is within the supported range;</li><li>Please confirm whether the signal source is connected to the HDMI input of the transmitter;</li></ol>                                                                                                                                         |
| **Short Transmission Distance** | <ol><li>The signal is weak, please adjust the antenna angle or the device placement;</li><li>Concrete walls, brick walls, wallpaper, metal doors, bullet-proof glass, etc. have a relatively large attenuation of RF signals. Please avoid such obstacles as much as possible in the straight transmission path;</li><li>Caused by co-channel interference. Please adjust the channel to avoid interference frequency;</li></ol> |
| **Image Lagged**                | <ol><li>The signal is weak, please adjust the antenna angle or the device placement;</li><li>Caused by co-channel interference. Please adjust the channel to avoid interference frequency;</li><li>The equipment is too far away. It's recommended to reduce the transmission distance appropriately;</li></ol>                                                                                                                  |
| **Infrared Return Invalid**     | <ol><li>Please confirm whether the infrared transmitter or receiver is inserted into the wrong hole;</li><li>The infrared transmitter should be placed in front of the receiving range of the receiving device as much as possible;</li></ol>                                                                                                                                                                                    |
| **Loopout Failure**             | <ol><li>Please confirm whether HDMI cable is well connected to HDMI output connector of transmitter;</li><li>If not, please plug it in and out again;</li></ol>                                                                                                                                                                                                                                                                  |
