Precautions on overhead projector use

(1) The OHP projection panel is designed to be used only with a penetration style projector (one whose projector is located underneath). • This product cannot be used with reflection style projectors. • Set the light power to less than 700 W when using a high light projector (one whose light power is over 700 W). • This product cannot be used with projectors using metallic halogen light. Doing so makes the OHP projection panel temperature extremely high and can result in device malfunction.

(2) When using an overhead projector with a zoom function, set the overhead projector stage to the lowest position.

Setting the stage in a higher position makes the OHP projection panel temperature extremely high and can result in device malfunction.

Precautions on temperature

(1) Do not leave the OHP projection panel on a projector stage for prolonged periods of time. Doing so may cause the display to darken or the unit itself to be deformed due to high temperatures. Because of this, the projector power should be turned off when not displaying an image. (The darkened display will return to normal once it cools down after moving the OHP projection panel away from the projector.) (2) When using the OHP projection panel for prolonged periods of time, its display may darken due to high temperatures. In this case, slide the contrast adjustor lever left in order to make it lighter. (3) Be careful when handling the OHP projection panel. Its surface temperature will become high during use. (4) Use this product at room temperatures between 0°C and 30°C (32°F to 86°F).
