Troubleshooting
No Sound
A properly connected system will take 5-10 seconds to link upon initial power-on. This
is normal. If there is still no sound, follow the steps listed below.
1. Make sure the transmitter input device is connected to the transmitter correctly.
2. Make sure the transmitter input selector switch is set correctly (speaker or RCA
input).
3. Make sure the transmitter input device has program material (music, DVD, etc.)
playing.
4. Make sure the transmitter input device is not muted and that the volume is turned
up to the desired level.
5. If necessary, temporarily connect a speaker to the transmitter input device and
make sure it is operating correctly. Also, make sure you are satisfied with the
sound quality since the wireless system cannot provide better output than what is
being input.
6. Check to make sure the transmitter and the speaker receiver power connections
are secure and that green lights are displayed on the transmitter and on the
receiver power brick. (See step 9 if the receiver LED is red.)
7. Verify that the transmitter signal input connections are secure.
8. Verify that speaker connections are secure at the bottom of the speaker stand base-
plate and at the speaker terminals.
9. If the transmitter green LED is on and the receiver LED is off, make sure the
receiver is plugged in and turned on. If the receiver LED is red and the transmitter
LED is green the system needs to be re-linked. Please see the linking instructions.
Linking
Linking is the way the system recognizes its own components by sending a message to
the receivers. This is transparent to the user and takes place automatically.
The system is shipped from the factory pre-linked and re-linking is normally not re-
quired. Rarely, however, there are conditions that require re-linking. For example, a
neighbor in an apartment dwelling might purchase the same system causing your re-
ceivers to respond to his transmitter.
Another possible reason for re-linking might be when a line transient or other electrical
event has corrupted the system address, in which case the receiver LED will appear
red.
Relinking is similar to restarting a computer and is easy to do. To re-link your system,
perform the following steps:
1. Slide the link switch left or right (it doesn't matter which way). The transmitter
green LED will flash on and off for a minute or two. If you hear program content
immediately you must still continue to link the receivers.
2. Walk over to each receiver and press the LINK switch. The transmitter green LED
blinking will pause (skip a beat) as an acknowledgement of the receiver link
switch being pressed. The receiver LED will change from red to green.
3. Repeat this operation for the other receiver. The system will now remember its
new address.
