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
