BEFORE TESTING YOUR DEVICE READ THIS ENTIRE MANUAL, ESPECIALLY THE SECTION ON
"IMPORTANT BATTERY INFORMATION".

Lightning Mode:

Test your new device right out of the box: Set the mode switch to "Lightning". Turn the power on. The
red LED will flash every time the device triggers. It's normal for it to trigger once on power up. If it
continues to trigger, check for light sources leaking into the room. (If you cover the window of the
device with your hand, it should not trigger). Set off a camera flash (using another camera or a flash
attachment). The flash should trigger the device.
Manual adjustment of the sensitivity is accomplished by adjusting the "trim screw" accessible on the left
side of the device (looking from above). The port in the most aft position is the sensitivity adjustment.
(The "forward port" is your cable connection). The Sensitivity Trim is a SINGLE TURN adjustment.
CAUTION: DO NOT ATTEMPT TO FORCE THE ADJUSTMENT BEYOND IT'S MECHANICAL STOPS. DOING SO
MAY DAMAGE THE SENSITIVITY ADJUSTMENT. Use a small jeweler's screwdriver, standard or Phillips) to
make the adjustments. Full CLOCKWISE sets the sensitivity at 120% of the factory set point. Full
COUNTER CLOCKWISE sets the sensitivity at 20% of the factory set point. We recommend for most
situations to use the normal set point which is approximately ¼ turn CCW from the full sensitivity point.
Other photography scenarios may dictate different settings at the professional photographer's
discretion.

Photographic Capture of Lightning:

The device triggers on the first bolt it detects and activates the shutter release of your camera within
0.3ms. Most lightning events last several hundred milliseconds.
Photographing Lightning is as much Art as it is Science. Getting the right conditions and settings can be
challenging, and some folks have a better knack for it than others. But to get you started, here are some
basic "recommendations":
