- 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 CFast card connector doesn't support hot plug. The pulling out opening of the CFast card cannot
be done in the state of power supply ON. Please neither pulling out opening of CFast in the state of
power supply ON of this product nor come in contact with CFast. This product may malfunction or
cause a failure.
- 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) CFast ---The OS-installed model uses a CFast card in the OS storage area.
The rewritable limit for the NandFlash is 60,000 times or more.
As a reference value, the rewritable lifetime can be determined by the following
calculating formula:
Rewritable lifetime (number of times) = ((capacity [MB]/management block size [MB])
× 60,000 times)/(number of management blocks rewritten each time)
Example:
If a 4MB file is created on a 4GB CFast card and is rewritten once every 10 seconds:
Rewritable lifetime = ((3,521/2) × 60,000)/2 = 52,815,000 (times)
Operating lifetime = 52,815,000/((60/10) × 60 × 24 × 365) = Approximately 17 (years).
(3) Touch panel--- The operating lifetime of the touch panel is at least 36 million touches
(as tested by mechanical touching under 250g 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).
* Replacement of expendables is handled as a repair (there will be a charge).
* Component life is not guaranteed value but only referential value.
