Notes:
• For best results, IR transmitter must be installed as shown with the LED's pointing toward the rear of the
vehicle (Fig. 1)
• Audio input can be connected to either a low-level fixed audio output or a variable level audio output (such as a
speaker or headphone output). If it is connected to a low-level output, only the volume control on the headphones
needs to be adjusted to control volume level. If connected to a variable level output, volume adjustment needs to be
done at both the source and at the headphones.
