Switching on the video camera
The Educam video camera has a 3-position switch at the rear of its base. Each position corresponds to a spe-
cific function:
Central position "0" -> TV camera off.
Position "I" -> the yellow LED is lit and the Educam is operating with video signal only.
Position "II" -> both the yellow and green LEDs are lit and the Educam is operating with both video and audio
signals.
Operation
Using the video camera
Position the camera head with the lens and the electronic sensor directly in front of the object that you wish
to observe using its flexible arm. The lens provided with the camera has a manual focusing and must there-
fore be adjusted every time the distance between the object and the camera is changed. This can be done by
simply turning the lens on the camera head. The object must be at least 0.76 mm away from the lens. There
are no limits to the maximum distance. To use the microphone to capture audio, put the camera base with the
microscope close to the audio source. It could happen that you hear a whistling noise while using the micro-
phone. This whistle is not a defect of the Educam camera, but a normal audio effect ("Larsen effect") that oc-
curs when the microscope is to close to the loudspeakers and the microphone is receiving the audio from the
loudspeakers. The intensity also depends on the dimension and size of the room.
The best solution to avoid this effect is to place the Educam video camera far from the loudspeakers, to use a
separated amplifier system and place it in a room without reverb. The "Larsen effect" will decrease in a room
with many people and many pieces of furniture.
Capturing video from a microscope
The Educam video camera has been designed for effective use with microscopes.
The following special adapters (provided) are required for this application:
Adapter for biological microscopes: To be used directly in the optical tube of the microscope after having ex-
tracted the eyepiece. This adapter contains a WF10x eyepiece that needs to be replaced with the one belong-
ing to the microscope.
MICROSCOPE
EYEPIECE TUBE
Adapter for stereo microscopes: To be used directly on one of the optical cylinders on a stereo microscope af-
ter having extracted the eyepiece. The biological microscope adapter needs to be inserted inside this adapter.
