[. . . ] â· Do not remove both the operating and memory backup batteries at the same time. The manufacturer is not responsible and provides no warranty for the malfunction, problems, or other damages caused by misuse of this product and its accessories by you or other third party. â· This product, including its accessories, are subject to change without notice for product improvement. When not using the overhead projection system or when carrying it, place it in its carrying case as illustrated. [. . . ] 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. Since this product is not waterproof, do not use it or store it where fluids, for example water, can splash onto it. (1) The OHP projection panel is designed to be used only with a penetration style projector (one whose projector is located underneath). â· This product cannot be used with reflection style projectors. â· Set the light power to less than 700 W when using a high light projector (one whose light power is over 700 W). â· 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. (1) Do not leave the OHP projection panel on a projector stage for prolonged periods of time. â· Should fluid from a leaking battery come into contact with your skin or clothes, immediately wash with clean water. â· If the product is not to be used for some time, to avoid damage to the unit from leaking batteries, remove them and store in a safe place. â· Do not fit partially used batteries, and be sure not to mix different batteries types. â· Do not throw batteries into a fire as this may result in an explosion. â· The original batteries were installed at the factory at the time of shipment and may be depleted before satisfying the full operating time indicated in the specifications. Please check that all the following accessories are included upon purchase. CAUTION: The cable connector of the OHP projection panel should only be connected to or disconnected from the OHP panel controller after turning off the power. Doing so while the power is on can cause the loss of function of all the keys of the OHP panel controller. 2) In order to prevent the OHP projection panel from falling off, tie the cable to the overhead projector pole using the fastening band. Turning the contrast knob to the counterclockwise makes the contrast lighter and turning it to the clockwise makes it darker. Finally, adjust the OHP projection panel position in order to fit the entire image on the screen. [. . . ] By using this AC adaptor, the operating battery consumption of the OHP panel controller can be reduced. â· Connect the AC adaptor after turning off the power of the OHP panel controller. If the following precautions are not observed, fire or electric shock may occur. Turn off the power to the OHP panel controller before unplugging the AC adaptor from the AC adaptor connector. [. . . ]
