Issue:	Cause and solution:
No	•	Check that the transmitter AC power adapter is fully inserted into the wall
sound		outlet and the power cord from the AC adapter is firmly connected to the
		transmitter power input jack.
	•	Confirm that the speakers are turned ON and tuned to the transmitter –
		the blue “tuned” indicator light should be glowing steadily.
	•	Confirm that the speaker AC power adapters are fully inserted into the wall
		outlet and the power cord from each AC power adapter is firmly
		connected to the speaker power input jack.
	or
	•	Check that the C-cell batteries are fresh and inserted with correct polarity
		(+, –).
	•	Check that the audio source component (stereo, TV, etc.) is turned on and
		transmitting sound as it normally should.
	•	Check that the speaker volume is turned up.
	•	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.

Issue:	Cause and solution:
No	• When using battery power, make sure the batteries are fresh and replace
sound/	if necessary.
distortion/	• Check that the speaker “tuned” indicator light is illuminated blue.
static	• Change the position of the channel select switch (1, 2 or 3) to change the
	operating frequency. The speaker will detect the loss of signal and
	retune automatically. However, you can also press the power/volume/scan
	control once to make the speaker retune.
	• Change the location of the transmitter. Place it as high and away from
	obstructions as possible. Avoid placing the transmitter directly on top of or
	behind a TV.
	• Move the transmitter and speakers closer together. Sending the signal
	through certain materials, such as glass, tile, and metal, can decrease the
	effective transmitting distance of the system.
