Environmental Considerations
The unit’s rugged design allows you to run your applications in
harsh outdoor environments. Here are some considerations that will
help you get the most out of your unit when working in very wet,
hot or cold conditions.
Water
This unit is designed to withstand accidental immersion. To
maintain the unit’s water resistant seal, it is important to ensure that
the CF-Cap is correctly oriented with the stylus holder facing the
front of the unit, and that the screw on the CF-Cap is tightened but
not over-tightened. Failure to reattach the CF-Cap screw could
cause leakage and will void your warranty.
Because the PowerBoot is designed to easily disconnect from the
unit, water can occasionally find its way onto the metal contacts
between the battery and the unit. After working in very wet
conditions remove the battery and check the contacts to see if they
are wet. If so, dry the contacts on both the unit and the battery with
a paper towel or clean cloth before storing for overnight or longer.
Temperature range
The operational temperature range is from -30°C to +60°C (-22°F to
+140° F). In addition, the unit can be stored at temperatures from
-40°C to +70°C (-40°F to +158°F). Although the unit is designed to
be rugged, do not leave it in direct sunlight or in a parked vehicle in
the sunlight for extended periods.
Batteries perform best at room temperatures. The battery also has a
very stable capacity as temperatures rise above the human comfort
level. However, cold temperatures cause battery life to drop, and the
colder the temperature the greater the reduction in available battery
life. Under very cold conditions (-20°C / -4°F and below), you can
expect your battery life to be shortened between 30 to 70 percent.
When working in very cold conditions, consider carrying a fully
charged, spare battery in a warm place. The unit is designed so that
battery replacement can be easily done. The battery performance
