Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Infrared Transmitters
The infrared transmitters consist of six infrared diodes. They are located behind a plastic cover in the housing of the rear display.
The RSE control unit powers the infrared transmitters which use infrared light to transmit the audio signals to the headphones. The infrared diodes begin to light as soon as the RSE control unit is switched on.
The infrared diodes then stay on for as long as at least one side of the RSE is still active. The diodes go out 5 seconds after switching off the last rear display.
The infrared transmitters use the following frequencies to send the audio signals:
| Left channel | Right channel |
|---|---|
| 2.3 MHz | 3.2 MHz |
| 2.8 MHz | 3.8 MHz |
To ensure trouble-free operation of the infrared headphones, note the following:
- An unimpeded line of sight between the receiver on the headphones and the infrared transmitter is essential.
- The cover on the infrared transmitter is clean and free from scratches.
