7. Why is the image projected in the shape of a trapezium? Why must it be adjusted,
and how to do so?
•
It sometimes happens that the projector is not level (for example, because
the front is higher than the back, or vice-versa) and consequently the
image projected is trapezoidal in shape.
•
A trapezoidal image is a distorted image and it must be adjusted until a
normal projection is achieved.
•
Generally speaking, the image can be adjusted by using a remote control
device or by correcting the height of the projector. For detailed
information, refer to the User Manual provided with the projector.
8. What type of projector must be used with the Interactive Whiteboard?
The projector must satisfy the three following requisites. It must:
•
be a front projector;
•
support the computer resolution;
•
have a minimum luminous flux exceeding 500 Lumens. For the precise
amount, the room size must be taken into account.
9. What to do when an unerasable colour pen has been used to write on the
whiteboard?
Never use colour pens to write on the Oliboard! Should this happen, clean the
whiteboard lightly using cotton-wool dampened with alcohol.
