Important Notes
For best results, the IR transmitter must be installed as shown in figure 1
with the LEDs pointing towards the rear of the vehicle.
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
outputs, then the volume adjustment needs to be accomplished at both the
sources and at the headphones.
