Mount the device in your camera’s hot shoe mount with the red semi-clear window facing the

direction you are photographing. Insert the supplied plug into your camera remote shutter

interface.

Point the camera at the storm or in the direction you see lightning activity.

Set your Auto Focus feature to OFF or Disable.

Set the focus to infinity. (If the lightning is closer than that, you’re too close to it!!!)

We’ve found that when photographing lightning at night, an f-stop of 5.6 works well.

Shutter speed should be long for night shots, 2-10 seconds. For daytime shots, don’t exceed 1

second and you’ll need a smaller aperture/ larger f-stop as well.

Turn the lightning trigger device power on FIRST before you power up the camera. (When the

trigger is first tuned on, it will trigger once on power up . . . not a big deal for digital

photography, but if you use film, you’ll lose one frame.)

Avoid using your cell phone near the device while it’s operating. Your lightning shutter trigger is

a sensitive device and can be triggered inadvertently by strong, nearby RF transmissions.

Motion Mode:
Your AEO MultiTrigger Pro is equipped with a passive PIR 10 meter motion detector. Motion is detected
via changes in the Infrared within the field of view of the device. The spectrum of the detector is in the
LWIR, meaning that it will only detect movement of IR sources that generate heat, such as an animal or
a human. Since LWIR is NOT transmissive through materials such as glass and acrylic, your trigger will
NOT sense motion through a window. At the sensors limits of 10 meters, larger object such as humans,
deer and bear should be detectable. Up closer, the sensor will detect movement of smaller objects. The
field of view is approximately 35 degrees, so you may need to position the sensor carefully so as to
detect motion in the area you wish to photograph.
The Hot Shoe mount on your trigger also includes a standard ¼-20 female thread for mounting on a

tripod. This free’s up your hot shoe for other accessories such as a flash.

To operate in “Motion Detection Mode”, simply place the Mode Switch in the “Motion” Position. To

test your device, connect your camera as outlined previously in the “Lightning Detection” Mode. Wave

your hand in front of the detector to ensure it triggers properly. Experiment with walking in front of the

trigger to establish your effective field of view at various distances.

IMPORTANT BATTERY INFORMATION: The LS 4.0 Lithium Series Triggers are designed to operate with a

single Li-Ion 14500 3.7V rechargeable battery ONLY. Using any other type of battery may cause damage

to the charging system (PRO Models) and the battery itself.

In accordance with postal regulations regarding the shipment of Li-Ion batteries, your AEO LS 4.0 Trigger

is shipped with a partially depleted rechargeable Li-Ion 14500 battery. Before using your device, ensure

the battery has been completely charged. Once charged, the device is designed to operate for over 180

hours continuously on a single charge.

Pro Models are equipped with a built in Li-Ion battery charger that derives power from any USB source

via a Micro-B USB connector on the RIGHT side of the device. When powered via USB, the USB LED

indicator is ORANGE during a charge cycle, GREEN when the charge cycle is complete

INSTALLING NEW BATTERY: AEO RECOMMENDS THAT YOU NEVER OPEN THE BATTERY

COMPARTMENT ON OUR PRO MODELS. THE BUILT-IN CHARGER NEGATES THE NEED TO REMOVE THE

CELL FOR CHARGING. IF THE CELL IS REMOVED AND RE-INSERTED REVERSE POLARITY, THE DEVICE
