-
When the surface or frame of the touch panel has become dirty, wipe it with neutral detergent. Do not
wipe the touch panel with thinner, alcohol, ammonia, or a strong chlorinated solvent.
-
It is a characteristic of analog touch panels that their resistance may vary with changes to the ambient
environment (temperature and humidity) and with their own aging, resulting in the deviation of the
detection point. If this is the case, calibrate the touch panel again to re-set calibration data.
-
LCD may have a few bright spots that are always on or a few black spots that are always off. Color
irregularity may also occur depending on the viewing angle. This however is due to the structural
characteristics of the LCD; therefore, it is not a product fault.
-
Burn-in on TFT Display
“Burn-in” may occur if the same display is retained for a long time. Avoid this by periodically
switching the display so that the same display is not maintained for a long time.
* Burn-In : Phenomenon characterized by a TFT display as a result of long-time display of the same
screen where a shadow-like trace persists because electric charge remains in the LCD
element even after the patterns are changed.
-
The CF card connector doesn't support hot plug. The pulling out opening of the CF card cannot be
done in the state of power supply ON. Please neither pulling out opening of CF in the state of power
supply ON of this product nor come in contact with CF. This product may malfunction or cause a
failure.
-
Do not put the PT-E on any object. Doing so can cause a failure.
-
Do not touch the conductive areas and electronic parts of the PT-E directly.
Doing so can malfunction or fail the PT-E.
-
When disconnecting the cables connected to the PT-E, do not hold and pull the cable part.
Doing so can cause damage to the PT-E and/or cables or a malfunction due to poor cable connection.
-
Do not block the air vents. Doing so can cause a fire.
-
When carrying the PT-E, always do it after powering off the PT-E. Also disconnect all connection
cords.
Not doing so can cause a fire or electric shock.
-
When the equipment will be left unused for an extended period of time, power off the PT-E.
Not doing so can cause a fire due to accumulated dust.
-
Before starting the fitting of the expansion board or memory, always touch any metallic area.
Starting the work with your body charged with static electricity can damage the electronic parts.
- Component
Life:
(1) Battery---The internal calendar clock and CMOS RAM are backed by a Lithium primary battery.
The backup time at a temperature of 25°C with the power disconnected is 10 years or
more.
(2) CF
---The OS-installed model uses a CF card in the OS storage area.
Estimated failure rates: 100,000 rewrite cycles, 500,000 hours MTBF
(3) Touch panel---
The operating lifetime of the touch panel is at least 1 million touches
(as tested by mechanical touching under 300g of force at a rate of two presses
per second).
(4) LCD backlight--- Display brightness decreases over time with use.
The operating lifetime of the backlight is 50,000 hours (the time until the
brightness is lowered to 50% of the initial value at atemperature of 25°C).
