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, turn the contrast knob to the counterclockwise 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 panel controller from shock. Place the hard cover on the OHP
panel controller when not using the OHP panel controller or when carrying it in its carrying case.
1) When using the OHP panel controller
2) When not using the OHP panel controller

2. About the power supply
The OHP panel controller included with this product requires two kinds of batteries, one for its
operation and the other for its memory backup. Please install all four included batteries before the
first usage. Please refer to the EL-9450 operation manual to find out how to install the operation
batteries. Note that the memory backup battery has been installed at the factory at the time of
shipment.
When the batteries need to be replaced
• The following conditions indicate the main batteries are depleted.
1) Nothing is displayed even if the O key is pressed.
2) The power suddenly goes off in the middle of operation.
3) The batteries replacement message is displayed.
Replace the batteries immediately if any one of these conditions occurs.
• Replace the memory backup battery at least once every 5 years. Record the date the memory
backup battery was replaced to estimate the next replacement date.
When nothing is displayed even though the O key is pressed or if the operating batteries
replacement message is displayed, the main batteries may be depleted. In that case, replace
the main batteries first.
If the memory backup battery is replaced while the main batteries are depleted, the memory
contents of the OHP panel controller may be lost.
• Please refer to the EL-9450 operation manual to find out how to replace the operation batteries
and memory backup batteries.
Precautions on battery use
Battery Handling Notes
Batteries, if misused, can explode or cause electrolyte leakage. Pay special attention to the
following points:
1. Be sure to replace all four dry batteries at the same time.
2. Do not use new batteries with used batteries in the same unit.
3. Replacement batteries should be of the same type as those to be replaced.
Some types of batteries are rechargeable, while other types are not. Carefully read the type
description on the battery and choose the unrechargeable type.
4. Insert the batteries in the correct orientations as indicated in the battery compartments.
Caution:
• Fluid from a leaking battery accidentally entering an eye could result in serious injury. Should
this occur, wash with clean water and immediately consult a doctor.
• Should fluid from a leaking battery come into contact with your skin or clothes, immediately
wash with clean water.
• 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.
• Do not leave exhausted batteries inside the product.
• Do not fit partially used batteries, and be sure not to mix different batteries types.
•Keep batteries out of the reach of children.
5
• Remove used batteries from the compartment. Otherwise, the calculator may be damaged from
electrolyte leakage.
• Do not throw batteries into a fire as this may result in an explosion.
• 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.
3. Checking the accessories
Please check that all the following accessories are included upon purchase.
• OHP projection panel main unit
• OHP panel controller main unit
• AAA dry cell battery × 4
• Lithium battery (installed in the OHP panel controller)
• Communication cable
• Carrying case
• Operation manual
•AC adapter EA-28A (included in products for the U.S.A. and Canada, optional for other areas)

Using the OHP System
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. In the event that such a
situation occurs, press the RESET switch that is located on the back of the OHP panel controller.
Please refer to page 11 for RESET switch operation details.
1. Controlling the OHP projection panel
1) Place the OHP projection panel on the overhead projector stage.
2) In order to prevent the OHP projection panel from falling off, tie the cable to the overhead
projector pole using the fastening band.
3) Press @ o of the OHP panel controller to turn the power off.
4) Plug in the cable connector of the OHP projection panel straight into the connection terminal
of the OHP panel controller.
OHP panel controller
• Ensure that it won’t detach by slightly pulling the cord.
Caution:
Do not plug in the connector upside down. Plugging it in by force can damage the connector and
the OHP panel controller.
5) Press the RESET switch that is located on the back of the OHP panel controller. Please refer
to page 11 for the reset switch operation details.
However, make sure to press O in screen 2. All of the memory contents will be cleared if
C is pressed.
6) Press O of the OHP panel controller to turn the power on.
7) Turn on the power of the overhead projector.
8) Adjust the contrast of the OHP projection panel screen using the OHP projection panel
contrast knob if necessary.
Tu r ning 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.

2. Detaching the OHP projection panel and the
OHP panel controller
1) Press @ o of the OHP panel controller to turn the power off.
2) Unplug the cable connector from the OHP panel controller. Pull straight while pressing the
buttons on both sides of the connector when you unplug the connector from the OHP panel
controller.
3) Remove the cable band from the overhead projector pole.
3. Using the OHP panel controller separately
The OHP panel controller can be used separately as a regular graphic scientific calculator.
Please refer to the EL-9450 operation manual on how to use the graphic scientific calculator.
