When using the GP with transportation vehicles (trains, cars, and ships), disaster and crime prevention
devices, various types of safety equipment, and medical devices that are not life-support related, use
redundant and/or failsafe system designs to ensure proper reliability and safety.
After the GP unit's backlight burns out the touch panel is still active, unlike the GP unit's "Standby Mode".
If the operator fails to notice that the backlight is burned out and touches the panel, a potentially danger-
ous machine operation error can occur. Therefore, do not create GP unit touch panel switches that may
cause injury and/or equipment damage. If your GP unit's backlight suddenly turns OFF, use the following
steps to determine if the backlight is actually burned out.
1) If the GP unit's "Backlight Control" is not set and the screen has gone blank, your backlight is burned
out.
2) If the GP unit's "Backlight Control" is set to Standby Mode and the screen has gone blank, and touching
the screen or performing another input operation does not cause the display to reappear, your backlight
is burned out.
Do not disassemble or modify the GP unit. Doing so may cause a fire or an electric shock.
Do not operate the GP in an environment where flammable gases are present, since it may cause an
explosion.
To prevent electrical shock or equipment damage, unplug the GP unit's power cord from the power supply
prior to installing or wiring the GP.
To prevent an electric shock, be sure to disconnect your GP unit's power cord from the power supply
before wiring the GP.
Do not use voltage beyond the GP unit's specified range. Doing so may cause a fire or an electric shock.
Do not connect or disconnect Host and GP unit communication cables while the GP is turned ON.
Do not replace the GP unit's battery yourself. The GP uses a lithium battery for backing up its internal
clock data and the battery may explode if it is replaced incorrectly. When replacement is required, please
contact your local GP distributor.
