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	• Move closer to the transmitter with the headphones on. Sending the signal
sound	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	• Make sure the headphones are charged and that the transmitter is properly
light up	connected to the audio source. Then, move the headphones close to the
	transmitter and press the headphone power button again.
Headphones	• Move closer to the transmitter.
shut off	• The headphones’ rechargeable battery needs to be recharged. Use the charging
automatically
	cable on the transmitter to recharge the headphones.
Headphones	• If you’re trying to find a different channel on the transmitter, the headphones
start beeping	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.
