TROUBLESHOOTING

Refer to this troubleshooting section if you encounter any difficulties in setting up and using your headphones.

PROBLEM	SOLUTION
No sound heard	A)	Check that your audio source, recharging
through the		cradle/transmitter and headphones are
headphones		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.
Poor sound quality	A)	Check to ensure that the sound provided
or interference		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.
Power cut off	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.
