Issue: Cause and solution:
No sound • Make sure the transmitter’s AC power adapter is fully inserted into the wall
outlet and the power cord from the AC adapter is firmly connected to the
transmitter power input jack.
• Check that the audio source component (DVD player, TV, etc.) is turned on and
transmitting sound as it normally should. If you’re using a PC or DVD player,
make sure you’ve selected the correct audio output and that the sound is not
muted.
• Confirm that the headphones are turned on (the LED is blue) and tuned to the
transmitter. If the LED is not blue, press the ch select key on the transmitter to
try a different channel. If this doesn’t work, press and hold the mute/link key on
the headphone and the ch select/link key on the transmitter simultaneously for 3
seconds.
• Make sure the headphones are charged—the LED on the right headphone should
be blue.
• Check that the headphone volume is turned up.
• If you’re using a variable output audio source (like a headphone jack or variable
output on a TV set), make sure the source component’s volume is set high
enough for the transmitter to detect.
• If you are using a Tape 2 Monitor output from your receiver/amp as the audio
output, check that you have pressed the Tape Monitor/Tape 2 button on the
front of the receiver. This will turn on the Tape 2 outputs, which may not have
been active.
Interrupted
sound
• Move closer to the transmitter with the headphones on. Sending the signal
through certain materials, such as glass, tile, and metal, can decrease the effective
transmitting distance of the system.
• Try a different channel from the transmitter: press the ch select key on the
transmitter’s top panel.
LED fails to
light up
• Make sure the headphones are charged and that the transmitter is properly
connected to the audio source. Then, move the headphones close to the
transmitter and press the headphone power button again.
Headphones
shut off
automatically
• Move closer to the transmitter.
• The headphones’ rechargeable battery needs to be recharged. Use the charging
cable on the transmitter to recharge the headphones.
Headphones
start beeping
• If you’re trying to find a different channel on the transmitter, the headphones
beep when they lock onto a new channel.
• The headphones beep every few seconds when the batteries are running low. Use
the charging cable on the transmitter to recharge the headphones.
