Chapter 4 - Maintenance
While the MP1X20A system is ruggedly designed and constructed, it is still a sensitive computing device
and should be treated accordingly. Do not subject it to abuse such as dropping it or letting it bounce
around in the back of a vehicle. It does not need to be babied but, on the other hand, it does need to be
carefully handled to assure reliable operation. It is a fairly large, unwieldy, and heavy device.
4.1 Handling of the system:
You should always make sure the keyboard assembly is properly latched onto the MP1X20A before
transporting it. This will ensure you do not lose the keyboard as well as it will protect the LCD screen.
You may transport the system in its carrying case, or you can carry the MP1X20A by its handle located
on top of the machine. The handle is attached securely to the strongest part of the machine and
distributes the load of the MP1X20A evenly to allow easy carriage and comfortable balance.
4.2 Handling of Cables:
All cables should be treated with care. Do not over extend any cable as this could result in breakage
internally in the cable. It is essential that cables with its plug be handled without force on the connector.
4.3 Handling of the LCD:
Do not use any abrasive material that might scratch the LCD screen. Do not apply any pressure to the
surface of the LCD screen either with objects or fingers; this will ensure that the screens do not suffer
from internal damage or cracks.
4.4 AC Power:
Always make sure the power cord is in good condition before using with the MP1X20A. Make sure your
power source is reliable and of proper standard. The MP1X20A power supply is capable of handling
typical 100-240V and 50-60Hz inputs. Do not use the MP1X20A on an already overloaded circuit. PS/2
style power supplies do not offer much in the way of surge protection or lightening overload protection.
It is always a good idea with any computer to provide a surge protector in line with the AC power to
protect the system. The MP1X20A does not provide internal battery backup.
4.5 Handling of the Keyboard / Touchpad:
The keyboard is not sealed. Do not subject the keyboard to spilled liquids or small debris (which might
jam the keys). The touch pad surface should be kept dry and clean for proper usage.
4.6 Cleaning the LCDs:
1. Do not use a cleaner that contains alcohol.
2. Do not use cloths that could be abrasive to the surface of the LCD.
3. Always gently wipe the LCD surface when cleaning.
4.7 Cleaning the Keyboard / Touchpad:
1. Do not spill any liquid on to the keyboard.
2. Do not drop particle into the spacing between keys.
3. Using a compressed air cleaner, you can remove the dust build-up within.
4.8 Cleaning the Fan Filter:
1. Remove the filter from its housing.
2. Use a compressed air cleaner to blow off the dust from the filter.
3. If necessary, you can wash the filter material, but do remember to dry it first.
