If you suspect that you have a bad sensor/LED pair, use the EXATRON LED checker part #3000-052 (small
blue plastic box.) This diagnostic tool is equipped with a transistor (blue/white wires) and an IR LED
(orange/green wires.)
Direct the transistor at any of the handler's IR LEDs. The LED on the checker should turn off. Direct the
checker's LED at any of the handler's transistors. The corresponding number should turn OFF on the
handler's display.
