Symptom

Suggestion

The system does not
power on.

•

Make sure that the AC adapter is plugged into the transmitter and the
wall outlet.

•

Make sure that the transmitter power cord is plugged into the wall outlet.

The system is not receiving
a signal.

•

Make sure both units are powered on and that your audio source is
turned on and operating.

•

Make sure that your speakers are hooked up properly.

•

Make sure the green LED on the receiver is illuminated. If it is not lit or it
is flickering, adjust the antennas

•

If you have set a personal ID Code for your system, make sure that both
units are set to the same code.

The audio is distorted.

•

Make sure the audio going to the transmitter is not distorted.

•

If your transmitter is hooked up to a Dolby Digital processor or receiver,
try adjusting the input power level.

The system has noise.

•

Check that the antennas on the transmitter and receiver are in upright
positions with a clear line of sight to each other.

•

Move the transmitter and receiver closer together, but make sure they
are placed not less than three feet apart.

•

Cordless phones may cause some interference to the receiver. Position
the receiver farther away from these devices or change the channel on
the transmitter.

•

Metal objects, such as some building structural supports, can cause
interference. Try positioning antennas to face the ceiling. The signal will
bounce off the ceiling avoiding direct contact with metal.

•

Try switching to another frequency channel.

No sound from the rear
surround speakers

•

Check the volume level on the receiver to make sure it is turned up
enough to be in balance with the rest of your system.

•

Make sure the transmitter is turned on and the red LED is lit. When the
transmitter is in standby mode, the receiver is searching for a signal.

•

Disconnect the audio link’s transmitter and receiver from AC power for
30 seconds. Then reconnect.

No sound from one
speaker

•

Make sure the speaker is connected to the receiver.

•

Check the speaker balance on your audio source.

5GHz 802.11a WLAN
interference

•

Set your 5 GHz WLAN band to 5.15- 5.35 GHz band range. Avoid using
the 5.8 GHz band.
