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).
