TROUBLESHOOTING
This manual contains instructions for the TS120 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 TS120 is a useful troubleshooting aid.
The blue LED should light only when a remote command is being received. If the LED on the TS120
“flickers”, and the TS120 functions normally, there is no cause for concern, some stray IR signal are
being received by the TS120 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 TS120’s and on the main system unit. Look for
open, shorted or reversed wires.
3. Test for interference from the following sources:
• Neon, Compact Florecent Lighting (CFL), or halogen lights in the room
• Light dimmers, beginning with those closest to the TS120
Observe the TS120’s LED while performing all the tests. It is possible to have interference from
more than one source.
