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 screws on the CF-Cap are tightened but not over-tightened.
Removal of the back case torx screws, or failure to reattach the CF-
Cap screws could cause leakage and may 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 -22 °F to +140 °F (-30 °C
to +60 °C). 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 temperature. The battery also has a
very stable capacity as temperature rises 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 (-22°F / -30C and below), you can
expect your battery life to be shortened considerably. When
working in very cold conditions, consider carrying a fully charged,
spare battery in a warm place. The battery performance will
improve by keeping the unit and the spare battery warm (for
instance, keeping them inside your coat).
