TROUBLESHOOTING (continued)
PROBLEM
Interference:
Power auto-cut-off:
SOLUTION
A) On the back of the transmitter, there is a
CHANNEL TUNING THUMBWHEEL.
Select a different frequency channel by
turning the thumbwheel up or down. Then
adjust the thumbwheel on the channel
tuning control on the headphones until the
LED Indicator glows GREEN showing that
the channel has been properly tuned.
A) The transmitter has an auto-cut-off function.
When there is no audio signal (such as
when a CD has finished and the player
stops) for a period of about 90 seconds,
the power of the transmitter will be
automatically cut off. You will then hear
some noise from the headset and the
LED on the earcup will turn RED. Once an
audio signal is restored to the transmitter
(resume playing the CD or audio program),
then the LED on the transmitter will glow
RED indicating that it is transmitting audio
once again (the LED on the headphone
will turn back to GREEN to indicate
normal operation).
TROUBLESHOOTING
If you encounter any trouble in setting up the Headphones,
please check the following points:
PROBLEM
Distorted sound
quality or
unclear sound:
No sound from
the headphones:
Mono sound:
SOLUTION
A) Check if the sound of your audio source is
distorted and whether the volume control
is set to an adequate level.
B) Make sure that your audio equipment, the
transmitter and headphones are connected
properly and switched ON. If the batteries
in the headphones have insufficient power,
replace them with fresh batteries.
C) Check if you have selected the best channel.
Adjust the Channel Tuning once again to
check. If necessary, you may change the
setting of the transmitter by turning the
CHANNEL TUNING THUMBWHEEL up
or down, then adjusting the thumbwheel
on the HEADPHONES to tune in a better
channel setting to improve audio or
eliminate interference.
A) Check if the batteries are inserted properly
into the battery compartment and whether
the headphones are switched ON.
B) Check if the batteries in the headphones
have sufficient power—replace them
if necessary.
c) Check if the transmitter is properly
connected and powered on with the
AC/DC Adapter (the Power LED
Indicator should glow RED).
D) Check if all the cords are properly connected.
E) Check if the distance between the
headphones and transmitter are within the
effective range. (The effective range of the
device is approx. 100 feet). Move closer to
the transmitter to receive the sound.
A) Check if the audio source is mono only,
use a stereo audio source.
