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.
