4.5.
Handling and maintenance
Handle the device with care and pay attention to the following handling instructions:
•
Disconnect all cables to the device during welding or when performing other service to the
machine imposing a risk of damaging electronic devices.
•
Service and repair to the device shall only be made by authorized personnel. If the device
is opened by unauthorized personnel, its warranty will be void.
•
Scratches or other damages may occur to the display surface if it is exposed to sharp
objects, abrasives or heavy impacts. This must be avoided to increase the longevity of the
screen.
•
The internal eMMC flash storage has a limited number of write cycles. Therefore it is
recommended that the amount of writing to flash is limited within software applications.
•
Always consider personal safety when installing and operating the product. For example,
in vehicle installations, CrossControl does not recommend that the product is being
actively operated by the driver when a risk of injury to people or damage to property is
present.
4.5.1.
Cleaning
To ensure proper and reliable functionality over time, pay attention to the following cleaning
instructions and precautions:
•
Wipe the device clean from dirt using a soft damp cloth, preferably of microfiber type.
Larger amount of dry dust may be swept off using a soft brush before wiping clean.
•
Avoid using alkaline, alcoholic or other potentially adverse chemicals for cleaning as doing
so may damage the device. However, small amount isopropyl alcohol may be used for
removing harsh stains.
•
Avoid spraying or by other means applying larger amount of water or alcohol directly to the
device. Instead, lightly dampen a cloth before using it for cleaning the device.
•
After cleaning, make sure that the device surface is left dry.
•
Never use high-pressure air, vacuum, water or steam to clean the device.
4.5.2.
Real time clock battery
Time and date information is stored in a memory sustained by an internal back-up battery. The
battery is a 3V 1000mAh high operating temperature Poly-carbonmonofluoride Lithium battery.
The expected life time of the battery is approximately 20 years. The battery is not replaceable.

The eMMC is used in pseudo SLC mode and implements both static and dynamic wear levelling to reach the
best reliability. The number of program/erase cycles is between 20k to 60k depending on the manufacturer and
temperature. Our recommendation for the application software is to temporary cache in RAM and to write larger
chunks of data to the eMMC. This recommendation is not specific to eMMC but is applicable to all flash
memories.
