USEFUL INFORMATION 
Location 
A clean and moisture-free environment is preferred. Make room for air circulation. 
Avoid areas with: 
•  Sudden or extreme changes in temperature. 
•  Extreme heat. 
•  Strong electromagnetic fields (near television set, motor rotation area, etc.). 
•  Dust or high humidity. 
If it is necessary to work in a hostile environment, please regularly maintain your 
computer by cleaning dust, water, etc. to keep it in optimal condition. 
Ruggedness 
The 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 computer is 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 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 exposed to water or moisture. Corrosion is 
accelerated if the system’s 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.
