( Operating the system
Listening to a
program
1
Turn on the audio/video
equipment connected to the
transmitter.
When the audio signals is input,
the transmitter turns on
automatically and the infrared
emitters glow. If the transmitter is
connected to the headphone jack,
set the volume control of the
audio source equipment as high
as possible but not so high that
the audio signal gets distorted.
(Around level 5 or 6 on the
volume control should be
appropriate.)
2
Put on the headphones and the
power turns on automatically. The
power indicator glows red when
the power turns on.
3
Adjust the volume.
Auto power on/off function
When you remove the headphones, the
power turns off automatically. Do not
pull up the self adjusting band when
not using the headphones, otherwise
the headphones will be switched on.
Mute function
If a hissing noise is heard when the
infrared rays are obstructed, or the
headphones are used outside of the
effective range (see the next section),
the mute function will be activated and
the sound will not be heard from the
headphones. To restore the sound,
move nearer toward the transmitter or
remove the obstruction.
When no audio signal is received at
the transmitter input for more than
approximately five minutes
The transmitter will be turned off
automatically.
After listening to a program
Take the headphones off before the
transmitter turns off. Otherwise you
may hear some noise when the infrared
rays are suddenly cut off.
Note
The infrared emitters light up when the
transmitter is turned on. The brightness of the
emitters may not be uniform, however, this is not
a malfunction.
