SOLUTION
A) Check that your audio source, recharging
cradle/transmitter and headphones are
connected, supplied properly and turned on.
B) Check to ensure that the rechargeable
batteries are installed in the headset
correctly and have been recharged properly.
C) Check to ensure the recharging cradle/
transmitter is running and the power
indicator light on the unit is lit.
D) Check that the audio source is delivering
a sufficient signal to the recharging cradle/
transmitter’s AUDIO IN input jack.
A) Check to ensure that the sound provided
by the audio source is loud enough and
of sufficient quality.
B) Check if the batteries in the headphones have
sufficient power. Recharge or replace them,
if necessary.
C) Check to see if you have selected the best
transmission channel (1, 2, or 3) to provide
the optimum signal reception. If necessary,
try another channel, remembering to fine-
tune the reception using the tuning control.
D) Check if the distance between the
headphones and the recharging cradle/
transmitter is within the operating range.
(The effective range of this device is up to
150 feet/45 meters from the cradle/
transmitter.)* If out of range, move closer to
the recharging cradle/transmitter to receive
the sound.
E) Check that the audio source provides
stereo sound.
The recharging cradle/transmitter has an
automatic power off function. When no signal
is received for 2 minutes through the recharging
cradle/transmitter’s AUDIO IN input jack, it
switches off. Switch on your audio source again,
and use the tuning control to adjust reception. If
necessary, increase the audio source’s volume.
