Before using
1. Caution
• Do not drop, apply excessive force, or carry it in the back pocket of slacks or trousers. Doing so
may cause it to become damaged.
• Do not leave it exposed to direct sunlight in a car or other places, or leave it near a heater. High
temperature can cause deformation and malfunction.
• Do not strongly press the display or keys, tap them with your finger nail, hard or sharp object, or
press them more than necessary. Doing so might cause the display and keys to become broken
or damaged.
• Do not use volatile agents (thinner, benzene and etc.) or a wet cloth to clean it. Always use a
soft dry cloth. Failure to do so can cause the product to deteriorate or be discolored.
• Since this product is not waterproof, do not use it or store it where fluids, for example water, can
splash onto it. Raindrops, water spray, juice, coffee, steam, perspiration, etc. will also cause
malfunction.
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.
(Penetration style) (Reflection style)
(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.
3
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).
Using the hard cover
The hard cover protects the OHP projection panel controller from shock. Place the hard cover on
