GENERAL PRECAUTIONS
· The OHP projection unit is designed for use with transmission (bottom projector) type overhead
projectors. It cannot be used with reflection type overhead projectors and zoom type overhead
projectors. Also note that certain types of transmission (bottom projector) type overhead projectors
produce better results. High luminance projectors (rated at 700 W) may cause blotches to appear on
the display of the OHP projection unit or may make the figures on the display difficult to see, especially
during presentations that take a long time. In such cases, use an overhead projector with a wattage
rating that is less than 700 W.
Check the rated wattage of overhead projector that will be available for your presentation before
planning to use the OHP projection unit.
· Note that the surface of the OHP projection unit can become very hot after long use with an overhead
projector. The bottom surface of the unit can become especially hot. Handle the unit carefully after
use with a projector to avoid burns.
· To avoid heat-related problems, remove the OHP projection unit from the overhead projector
whenever possible (when projection of the OHP projection unit image is not necessary) to avoid
problems caused by overexposure to heat. It is also a good idea to switch off the power or the lamp
of your overhead projector when it is not being used for projection.
· The special heat-resistant display of the OHP projection unit protects it against damage from heat
generated by the overhead projector lamp. Note, however, that the OHP projection unit should not
be used in environment in which room temperature exceeds 30
°C (86 °F).
· Low room temperature can cause the liquid crystal display of the OHP projection unit to become dim
and difficult to read. Use the unit at room temperatures above 10
°C (50 °F).
· The foil on the back of the OHP projection unit is put there to reflect heat. Do not cover this foil, write
on it, or otherwise cause it to become soiled. Doing so can hinder the unit's ability to resist heat
damage.
· Never place the OHP projection unit face down on the projector.
· The OHP projection unit uses a special liquid crystal display designed to produce text on OHP
screens. Because of this, it has yellow bands that are not present on the displays of standard graphic
scientific calculators.
· To allow clear projection of the displayed image, no layer of glass is used to protect the surface of
the liquid crystal display. Be careful when handling the unit, and never touch the unit with hard, pointed
objects, such as pens, pencils, etc.
· When using the OHP projection unit with a projector, place its display in the center of the stage of the
projector.
· Should the display of the OHP projection unit becomes soiled, wipe it off as soon as possible with a
soft cloth. Never use thinner, benzine, or other volatile chemicals to clean the display.
· Be sure to read the manual for the overhead projector you are using for other precautions regarding
its use.
