TROUBLESHOOTING (CONTINUED)
ELIMINATING OPTICAL FEEDBACK
In some installations, two conditions combine to create an optical feedback loop. Symptoms can
include: poor range, intermittent operation or no operation.
The conditions which sometimes combine to create a feedback loop are:
1. Both a sensor and a flasher are located within the same room.
2. There is some low-level noise or interference on your system.
You can eliminate optical feedback by replacing any IRB1 “flooding flasher” with MF1 or MF2
MicroFlashers
®
and covering all flashers with the supplied IR blocking covers.
IDENTIFYING THE TYPE OF INTERFERENCE
The “flash-back” LED on the front of the WS110R 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 WS110R “flickers”, and the WS110R functions normally, there is no cause for concern.
IF THE WS110R 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 WS110R’s Main System Unit and on the IR main system
unit. Consult your IR Main System Unit’s manual for more detail.
IF THE WS110R 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.
