Indicator Status

Refer to table 1-1 for indicator status.
1. If both yellow LED indicators (signal margin/reset mode) are illuminated, the receiver is not
receiving light (an optical signal) from the emitter. Align the emitter and receiver.
2. If the signal margin indicator flickers and the reset mode indicator is illuminated, the optical
signal is too weak for the perimeter device to operated correctly. Continue to align the
emitter and receiver.
3. If both yellow indicators (signal margin/reset mode) flicker, the optical signal is close to the
limit. The receiver is receiving enough of a signal to operate correctly. However, continue
to align the emitter and receiver for optimum performance.
4. If the signal margin indicator is not illuminated and the reset mode indicator is flickering,
the alignment is correct. Press and release the push-button within the correct time frame
(100 ms < t < 3,4 s).
5. If the signal margin indicator is not illuminated, and the reset indicator is illuminated, the
device is 100% aligned and operating correctly.
