In order to test your emitter to make sure it's working: step 1 make sure your emitter is plugged into CN2 (you might have burned it out by plugging it into CN5). Step 2 is getting into test mode...on the DMD there are two switches next to each other, SW1 and SW2, you need to move both switches toward the communication cable connection. Step 3 is to make sure your apple is connected then turn on transmitter and tank. Step 4 is point the tank/emitter toward a white wall fairly close (1-3 feet), when you fire your battle unit receiver should light up. If it doesn't you either don't have the switches in the wrong position, emitter is not connected to CN2, apple is not secure correctly or your emitter/ir led is burned out. Hope this helps.
