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.
