*1 Bright dots (always lit) and dark dots (unlit) may appear on a liquid crystal display panel due to its characteristics. It is impossible
to completely avoid this symptom, as the liquid crystal display comprises of a great number of display elements. Flickers may be
observed depending on the display color.
Please note that these dots appear due to its characteristic and are not caused by product defect.
Flickers and partial discoloration may be generated on the liquid crystal display panel due to the display contents or the contrast
adjustment. However, please note that these phenomena appear due to its characteristic and are not caused by product defect.
There is a difference in the display brightness and the color tones between liquid crystal display panels. When using multiple
liquid crystal display panels, please note that there is an individual difference between them.
A crosstalk (shadow as an extension of the display) may appear on the liquid crystal display panel. Please note that it appears
due to its characteristic.
When the display section is seen from the outside of the display angle, the display color seems like it has changed. Please note
that it appears due to its characteristic. Especially, the response time of a STN liquid crystal display is slower in the lower
temperature due to its characteristic. Please use the display after checking the response time.
Please note that the response time, brightness and color of the liquid crystal display panel may vary depending on the usage
environmental temperature.
When the same screen is displayed for a long time, an incidental color or partial discoloration is generated on the screen due to
heat damage, and it may not disappear.
To prevent the heat damage, the screen saver function is effective.
For details on the screen saver function, refer to the following.
11.1 Display Setting
*2 Gradation inversion is a characteristic of liquid crystal display panel. Please be forewarned that depending on the displayed color,
the visualization may be difficult even within the described view angle.
*3 The GOT screen saving/backlight off function prevents images from becoming permanently etched on the display screen and
increases the backlight life.
11.1 Display Setting
*4 The touch panel is analog resistive film-type. If you touch the panel simultaneously in 2 points or more, the switch that is located
around the center of the touched point, if any, may operate. Do not touch the panel in 2 points or more simultaneously.
Do not press the GOT display section with a pointed material as a pen or driver. Doing so can result in a damage or failure of the
display section.
An analog resistive film-type touch panel does not require adjustment usually. However, misalignment between object position
and actual touched position may be caused as usage time passes. If misalignment between object position and actual touched
position may occur, adjust the touch panel position. Misalignment between object position and actual touched position may
operate an unintended object, which causes unintended operation by mis-output and mis-operation.
*5 ROM in which new data can be written without deleting the written data
*6 Set the terminating resistor selector switch of the GOT in accordance with the connection type when adopting GOT multidrop
connection.
*7 Note that this does not guarantee all user's operation environment. The protection is not applied when the interface environment
protection cover is removed.
In addition, the product may not be used in environments under exposition of oil or chemicals for a long period of time, or in
environments filled with oil-mist.

POINT
Operation at momentary power failure
The GOT continues to operate even upon 5ms or shorter instantaneous power failure.
The GOT stops operating if there is extended power failure or voltage drop, while it automatically resumes
operation as soon as the power is restored.
