• Please remove the batteries in case you should not use the device for some time. This will prevent any leaking of the batteries. • Please clean the lenses occasionally with a soft cloth. © eltima electronic 2013... -
Page 6: Quick Start
• Install the light barrier and the 40mm reflector on one beam. The camera will be released. tripod each. • Plug the DC-plug in the DC-plug of the light barrier. At this point the LED will shine green. © eltima electronic 2013... -
Page 7: Functional Concept
Image 6: Light beam is interrupted This principle of function offers several advantages. First of all only one device, the light barrier itself, needs power supply, the other side, the reflector, is passive. © eltima electronic 2013... -

3-5 mm. The objects to be detected be the light barrier need to meet and interrupt this beam. The small diameter brings a very precise and repeatable switching point of the light barrier. © eltima electronic 2013... -
Page 9: Reflectors
It is totally sufficient when it looks roughly towards the latter. Solely for reaching the maximum working distance the reflector should be aligned precisely. © eltima electronic 2013... -
Page 10: Sensitivity
The less light is emitted by the IR-sender, the less will be returned to the receiver and thus the smaller the objects can be and still bring about a release of the camera. © eltima electronic 2013... -

Page 14: Release Delay, Lag Time
A strongly bent characteristic curve allows a very precise setting of up to one second, afterwards a rough setting of up to 10 seconds. The delay time is active in all operating modes except for the passive-mode, see Thunderstorm photography. © eltima electronic 2013... -

(im- age 14), otherwise you might move the light beam around the reflector and miss it (image 15). Image 15: missing the reflector © eltima electronic 2013... -

– the camera will be released if the subject will travel a certain distance away from the beam. light beam is interrupted. The right focus point has to be determined by a number of trials. © eltima electronic 2013... -

– especially when working with small focal lengths and thus with larger depths of field or when the objects are small compared to the depth of field. Table 7 shows the reflector´s possible reaches when using the palm of one´s hand as reflector. © eltima electronic 2013... -
