Introduction:
The Lightning Bug™ ’automates’ the process of taking pictures of lightning (or
other similar events**) by sensing changes in the infrared light, and snapping
your camera shutter at exactly the right moment.
To help you get the most out of your purchase please take a few minutes to
read this manual, or at the least skim over it for the good parts. If you still have
questions about using your Lightning Bug™, feel free to email our technical
support team at [e-mail]. We’ll be happy to assist.
** The Lightning Bug™ can be used to take photos of fireworks, cannon shots, virtually anything that produces a
fast-acting rise of light formed by a high-temperature event.

Battery Installation/ emoval:
The Lightning Bug™ case incorporates a battery compartment at the rear of the
unit. A small latch unlocks a removable battery compartment door.
A standard 9 Volt battery is required for operation. To insert it, gently pull the
9V connector wires out from the compartment and attach a battery. The leads
will only allow the battery to be connected in one direction, and snap in place.
After installation of the battery, the compartment door should be replaced – it
snaps into position with an audible click.
To remove the battery, reverse the process.
Please note:
MK Controls does not recommend leaving the battery in place during long
periods of disuse. There is a slight current draw whenever the battery is
inserted in the unit, and after a period of months, the battery may no longer
have sufficient operating power. In addition, batteries can, on occasion, leak
electrolytes. This fluid is corrosive, and can damage the circuitry of the
Lightning Bug™, in addition to the battery connector. The Warranty does not
cover damage due to a leaking battery.
echargeable batteries are not recommended for use in the Lightning Bug™ due
to the current consumption characteristics of the circuitry during operation.

Camera Connection:
Each Lightning Bug™ purchased includes one cable for connection to your
camera. Additional and/or replacement cables are available from MK Controls,
or your chosen reseller.
The camera connector has a 2.5mm stereo male plug on one end, and the
appropriate connector for your specific camera on the other. The 2.5mm
female socket is located at the lower right on the unit. When inserting the
cable, please make sure it is fully seated for proper operation.
The camera side connector is specific for the model camera you’re using –
please follow manufacturer’s recommendations for insertion of this connector.
When the Lightning Bug™ is powered on, it will automatically activate your
cameras meter (on cameras that support this feature). Turning the unit ‘off’
automatically will release the meter.
The Lightning Bug™ is designed to fit an industry standard shoe mount, and is
self-explanatory.

Operation:
The Lightning Bug™ has three ‘soft-touch’ buttons that are used to operate all of
the features:
On/Off
Decrease Sensitivity
Increase Sensitivity
On/Off: Press and hold this button for approximately 2 seconds turns the
Lightning Bug™ on or off. When the unit is first turned on, it will execute a
Power On Self-Test (POST), which will light up all of the LED’s and perform an
internal function verification. If during the POST you notice that any LED’s fail
to illuminate, please contact MK Controls Technical Support for troubleshooting
your unit.
Decrease Sensitivity: Tap this button to decrease the sensitivity of the Lightning
Bug™. When this button is pressed, the bargraph display (orange LED’s) will be
show the current sensitivity level. There are a total of 26 levels of available
sensitivity**. The factory default setting is level 12.
Increase Sensitivity: Tap this button to increase the sensitivity of the Lightning
Bug™. When this button is pressed, the bargraph display (orange LED’s) will be
show the current sensitivity level. There are a total of 26 levels of available
sensitivity**. The factory default setting is level 12.
** Determining the sensitivity level:
The orange LEDs will always display the current sensitivity level when the unit is
powered on, 1 being the least sensitive, and 26 being the highest. See Table 6.1
for more details.

Additional Features:
Adjust Frames Per Second:
You can adjust the maximum~ number of frames per second that the Lightning
Bug™ will cause a shutter trip. This can be adjusted from as few as 1 per
second, to as many as 10 per second. The factory default setting is 4 FPS.
To adjust the FPS, the unit must be powered on. Simultaneously press the
On/Off Button and the Decrease Sensitivity Button and hold them for
approximately 1 second.
+
The yellow detection light will flash at a rate of approximately 2 times per
second when this mode is correctly entered. Use the Sensitivity Buttons to
decrease or increase the number of frames per second. The orange LED display
will be updated to show the current setting. If no keystrokes are detected
within approximately 3 seconds, the FPS setting is stored, and the unit returns
to the normal operating mode (the yellow detection light will cease to flash).
Adjust Active/Inactive Meter Mode:
By default, the Lightning Bug™ will activate your camera’s meter anytime the
unit is powered on. This functions on most cameras as if the shutter was held
down halfway. This greatly reduces the lag between the Lightning Bug™
triggering the camera and the camera actually taking the image. In most
situations, this is the ideal setting as it decreases the chance of missing an
image.
For most cameras, powering off the Lightning Bug™ will deactivate the camera
meter. This allows easy review of any captured images.

Please note: We have found that some cameras, most notably Canon models
using the N3 style connector, ‘may’ keep the meter active whenever the
Lightning Bug™ is attached to the camera, even if the Lightning Bug™ is powered
off. With these cameras, you will need to unplug the Lightning Bug™ to review
images on the camera’s LCD.
In some situations, it may be desirable to have the Lightning Bug™ activate the
camera’s meter only when the shutter is triggered. This will allow you to review
your image on the camera’s LCD after the image is captured without turning off
the Lightning Bug™. Warning – if you enable this feature, you may miss shots.
Enabling this feature will increase the time it takes for the shutter to be
triggered by the Lightning Bug™
To modify this setting, the unit must first be powered on. Simultaneously press
the On/Off Button and the Increase Sensitivity Button and hold them for
approximately 1 second.
+
The yellow detection light will flash at a rate of approximately 2 times per
second when this mode is correctly entered. Press either Sensitivity Button to
toggle between the On and Off modes for automatic meter control. When the
automatic mode is On, the rightmost orange LED (below the + sign) will be
illuminated. When the automatic mode is Off, the leftmost orange LED (below
the – sign) will be illuminated.
When the automatic meter control if Off, the meter will remain OFF until the
shutter trips. When the automatic meter control is On (factory default), the
meter will remain ON whenever the Lightning Bug™ is powered on (and will be
turned OFF when the unit is powered off).
