Workplace
A clean and moisture-free environment is preferred. Make room for air
circulation. Remember to avoid areas from:
z Sudden or extreme changes in temperature.
z Extreme heat.
z Strong electromagnetic fields (near television set, motor rotation area,
etc.).
z Dust or high humidity.
If it is necessary to work in a hostile environment, please regularly maintain
your notebook computer by cleaning dust, water, and etc. to keep it in an
optimal condition.
Ruggedness
This notebook computer is designed with rugged features such as vibration,
shock, dust, and rain/ water protection. However, it is still necessary to provide
appropriate protection while operating in harsh environments.
The notebook computer is also designed to withstand rainfall from top with
mild wind blowing only. Please keep the keyboard facing up, i.e. normal
operating direction, to maintain water resistance. NEVER immerse the unit in
water, or spray water at an upside-down system. Doing so may cause
permanent damage.
The D-sub connector caps on the rear of the computer are for dust and shock
protection. The connectors are sealed internally. Other I/O ports and devices
on the left or right must have caps tightly closed or cable inlets sealed while
being exposed to water or dust.
There are optional gaskets for DB-9 and DB-25 connectors. You may install
them to improve rain/ dust/ moisture resistance on your commercial type cable.
Insert the packing into the male connector (with pins) and fasten the screws.
All connectors will be corroded if being exposed to water or moisture.
Corrosion is accelerated if the power is ON. Please take proper water-resistant
measures for cable connections. The DC jack and cables are sealed and may
be operated with water splashing while attached. All port covers should be in
place when no cable is attached.
