Identifying the type of interference
The “flash-back” LED on the front of the WS100R is a useful
trouble-shooting aid.
The LED should light blue only when a remote command is
being received. However, if the LED on the WS100R
“flickers”, and the WS100R functions normally, there is no
cause for concern.
If the WS100R does not work, and the LED does not
light at all:
Test the remote control(s) by operating the A/V
equipment directly. Replace the batteries if needed. Double
check the cable connections on all WS100R’s Main System
Unit and on the IR main system unit. Consult your IR Main
System Unit’s manual for more detail.
If the WS100R does not work, and the LED flickers or
remains solidly lit:
Cover up the Sensor with a piece of
cardboard (your hand will actually create electromagnetic
interference under some conditions). Observe the IR test LED.
IR Test LED Off:
Optical Interference.
IR Test LED On or Flickering:
Electromagnetic Interference.
EMI (Electromagnetic Interference)
Identify the source of the interference. The most common
sources of electromagnetic interference are listed in the
Installation Considerations section on page 3. To eliminate
EMI try the following methods:
