with the HiFi cable, as shown in Figure I.
2. Insert the DC connector of the AC/DC adaptor into
the 12V DC input connector on the rear of the IR
transmitter, as shown in figure I.
3. Ensure that the rated voltage of the AC/DC adaptor is
the same as the mains voltage before plugging it into
the mains power wall outlet.
4. Insert two batteries {R3.AAA) into the battery
compartments as shown in figure 2, ensuring that the
polarity is correct.
6. Operation
1. Switch on the IR transmitter and place it at the same
height or slightly higher than the reception height of
the IR headphone.
2. Position the LEDs towards the listening area, ensuring
that there are no obstacles in between.

comfortable listening level.
7. Positioning of IR transmitter
1. Place the IR transmitter unit so that the IR window
approximately faces the centre of your listening area,
see figure 3.
2. Because IR light travels in a straight line, place the IR
transmitter at the same height, or slightly higher than
the reception height of the IR headphone.
3. High IR light content such as sunlight and bright
incandescent indoor lighting may degrade the audio
signal and cause interference. If you experience such
problems, simply move the system to a darker area.
