The device has a ventilation membrane, refer to Figure 3 for the location. For proper
ventilation of the device, dirt and water must be prevented from accumulating and covering
the membrane. Be cautious not to insert objects which may puncture the membrane. Doing
so will violate the IP-classification and void the warranty of the device.
Install the device and any cables attached such that they are not subject to excess vibrations
or other potentially harmful stress.
Loose fasteners are a common cause for excessive vibration. Fasteners may come loose due
to improper mounting techniques such as omitting thread lockers (fluid locker or locking
washers) or by over/under-tightening. Proper tightening requires dry, clean fasteners and a
torque wrench.
If the device is exposed to chemicals, water, dirt or other pollutants, it’s recommended to
have it cleaned off as soon as possible. See chapter 3.5.1 for cleaning instructions.

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 device. For example, in
vehicle installations, CrossControl does not recommend that the device is being actively
operated by the driver when a risk of injury to people or damage to property is present.
3.5.1.
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.

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.
