Headphones set-up

We suggest first to choose Simolio’s infrared headphones to use. For other brand headphones, some issues maybe occurred because of their quality or parameters.

1. Make sure the headphones’s batteries are powerful enough to get good receiving effect.
2. Switch on your wireless infrared headphones and make sure they are on the same channel as the transmitter.
3. For Simolio’s infrared headphones, there are automatic power off function to prevent batteries from draining. If you forget to switch the headphones off, you need to switch it off and then to the same channel as the transmitter again when using next time.

Note:

• To watch two different movies in the same row, you need to connect two transmitters to two DVDs respectively, one of which uses channel A and the other uses channel B.
  

• For aftermarket Dual screen DVD player, we suggest to hook up the transmitter with your main unit, and only connect the video out RCA plug (yellow) to the secondary screen. The main unit will not produce sound out once the audio cords (RCA white and red) are plugged in the secondary screen. Remember to keep the video cord (yellow) connected with the secondary screen.
  

Operation for TV/Cable box/Home DVD/Direct TV/WiFi TV box

For home users, the situation is more complex in many cases. Make sure your TV/Smart TV box/Cable TV box/ Set-top box/DVD or other audio device has RCA

AUDIO OUT ports available. Check the side or rear of your TV/Cable TV box. If you only watch Cable TV, you can connect the transmitter to your Cable TV box too.For your TV, the ports arrangement maybe different. This figure is just for reference.

This transmitter does’t support the optical audio outputs. For most modern TVs which only have optical fiber audio out ports and streaming media programs directly from Smart WiFi TV, we suggest to buy a digital to analog converter to help you to hook up.
