This manual contains instructions for the WS120 only. For specific information on the adjustment
and operation of your Niles infrared extender system, please refer to the instruction manual included
with your Niles IR main system unit (MSU140, MSU250, MSU480, MSU440Z).
The bi-color blue/green LED on the front of the WS120 is a useful troubleshooting aid. The led
should light solid green when status is detected.
The blue LED should light only when a remote command is being received. If the LED on the WS120
“flickers”, and the WS120 functions normally, there is no cause for concern, some stray IR signal
are being received by the WS120 but are not being repeated.
1. Test the remote control(s) by operating the A/V equipment directly. Replace the batteries
if needed.
2. Double check the cable connections on all WS120’s and on the main system unit. Look for
open, shorted or reversed wires.
3. Test for interference from the following sources:
• Neon, Compact Florescent Lighting (CFL), or halogen lights in the room.
• Light dimmers, beginning with those closest to the WS120.
Observe the WS120’s LED while performing all the tests. It is possible to have interference from
more than one source.
