3-3 Handling of LCDs
1) The LCD display contains skin-irritating materials. If liquid materials flow out due to damage and comes in
contact with skin, wash the area under running water for at least 15 minutes and consult a doctor.
2) The LCD display might have uneven brightness according to the contents being displayed. This is not a
malfunction.
3) Minute spots (dark or bright) may occur in the LCD display elements. This is a basic characteristic of the
LCD display and not a malfunction.
4) When LCD display is viewed outside the specified view angel, the color might seem different. This is a basic
characteristic of the LCD display and not a malfunction.
5) When displaying a same image for a long period of time, it might cause an image lag. This is a basic
characteristic of the LCD display and not a malfunction.
In order to avoid image lags, please follow the below procedures:
1. When leaving the same image displayed, use the” display off” function.
2. Change the image displayed periodically and do not display the same image for a long period of time.
3-4 Handling of Touch Screens
1) If elements that change ambient environments or electric fields (capacitors with large capacity, power units,
and materials with high permittivity such as metals) are set close to the product, it might have impact to the
coordinate detection. Make sure to keep a good distance from the above unstable elements as much as
possible when designing.
2) Due to the characteristics of the touch screen, its functions might become unstable according to the
environment it is installed. For correct operations, perform sensitivity sensor calibration when building into a
device.
Also if at any time the touch screen operation become unstable due to changes in environment or
installation conditions, perform sensitivity sensor calibration.
3) The touch screen surface is made of glass. Glass is subject to break once scratched. Please handle with
care and avoid glass from contacting other glass and hard objects.

*1. Protection structure of the front part of the unit when installed to a panel. Although it has been
tested under conditions equivalent to the standards shown in the specification, use under all
environments are not guaranteed. Especially for oils defined in the test, in cases where EMG7
is prolonged to vaporized oils or cutting fluids with especially low viscosity, oil might enter the
front area through an area where touch screen has lifted and may need special
measurements. Please check the installation environment prior to use. Also, gaskets that
have been used for a long time or have once been installed to panels, the original level of the
protection cannot be guaranteed. To maintain the stable, original protection level, we
recommend replacing the installation gasket regularly.
