Troubleshooting:
The WA-320 transmitter is compliant with FCC Part 15, subpart C. The WA-360
receiver is compliant with FCC Part 15, subpart B. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
!
Reorient or relocate the receiving antenna.
!
Increase the separation between the equipment and receiver.
!
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
!
Consult the dealer or an experienced radio/TV technician for help.
!
Modifications not expressly approved by the manufacturer could void the user's
authority to operated the equipment under FCC rules.

Problem:
Hum in System
Troubleshooting:
Plug all parts of the system into the same outlet to see if
the hum goes away.
Cause:
The different components in the system are connected to different
electrical grounds. This forces electrical currents to find alternate paths to
ground causing an audible 60Hz hum.
Solution:
Plug products into an electrical circuit with a common ground. If it
can be done safely, consider lifting the ground with a ground lifting plug.
Problem:
Transmitter is not linking with the receiver.
Troubleshooting:
Make sure you are linking compatible models (WA-320
with WA-360). Check if pwr/lnk LED indicator on the transmitter is turning
amber and that the signal LED is lit.
Cause:
Link button on WA-360 is not being pressed quickly enough. Review
the linking procedure in this manual. Please note that a transmitter and
receiver will remain paired even after being unplugged. This allows you to
complete the linking process before placing the receiver in it’s final location.
Solution:
Press the Link button on the WA-320 and confirm that the pwr/lnk
LED turns amber. Within 6 seconds, press the Link button on the WA-360.
Problem:
Can’t link to the transmitter, or audio is cutting out.
Troubleshooting:
Check the source, is it sending a signal? Consider setting
the jumpers on the transmitter (WA-320/WA-321) to the “disable audio-
sensing” position during setup procedure (see the Rear Panel Features and
Connections section). This will ensure that the transmitter will not mute
during pauses or very quiet passages.
Cause:
Either there is no audio going into the transmitter, or the audio is very
quiet which is causing the transmitter to mute.
Solution:
Use a known good audio source. If you can’t find any other
problems, try using a different source component even if you think your audio
source is OK.
