Assembly
Power supply
The Educam Student video camera requires 12 V DC working voltage and comes with an external power supply.
Attach the video camera output cable of the Educam Student video camera to the external power supply socket,
and plug the power supply directly into a 220 V mains socket.
Video signal
The video signal from the Educam video camera is transmitted to a TV monitor. The video output signal cable
can be found on the back of the camera base. It is fitted with a yellow plug that should be plugged into the moni-
tor/colour TV directly or via the SCART adapter provided (in the yellow video socket).
Finally, if using the SCART adapter, it has to be inserted into the SCART socket at the back of the TV set. See
the TV manufacturer’s instruction manual for details of how to switch on the TV and use its SCART circuit.
Operation
Switching on and off the video camera
The Educam video camera has a switch at the rear of its base. Switch to “1” to turn on the video camera and to
“0” to turn it off.
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 therefore
be adjusted every time the distance between the object and the camera is changed. This can be done by sim-
ply 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.
