This cache is a gadget-cache, and it will require two AAA batteries. In order to find the combination to the lock on the bottom, follow these steps:
1. Open the side door and insert the batteries into the holder, flipping the switch to the "ON" position, the red LED should light up.
2. Remove the two wires from the side of the cache.
3. Using the two wires, connect THREE of the bolts, (this means that one bolt wil have two wires clipped to it), so that all three LEDS are illuminated.
Please replace the wires in the side, as the next cacher will need them, and remove your batteries, (they could corrode and ruin the cache if left in). I hope you have fun finding this cache, it's a few months in the making. I made it in my engineering class, and hand-soldered all of the LEDS. I have had some bad luck with my larger caches getting ransacked in the past, so I'm hoping that this one survives.
