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.
Keep the battery assembly and its connectors as dry as possible. If
the battery compartment does get wet, dry off the contacts as much
as possible. Removal of the back case screws could cause leakage
and may void your warranty.
NOTE: Although a custom cover for the I/O ports and the audio
jack are provided, these are not required to maintain the seal the
unit against water. The covers are intended to keep mud, sand and
other materials from blocking these ports.
Temperature range
:
The operational temperature range is from
-22 °F to +140 °F (-30 °C to +60 °C). The operational temperature
range for the WWAN units is from -4 °F to +140 °F (-20 °C to +60
°C). Although the unit is designed to be rugged, do not leave it in
direct sunlight or in a vehicle in the sunlight for extended periods.
Batteries perform best at room temperature. The battery has a stable
capacity as temperatures rise; however, the colder the temperature,
the greater the reduction in available battery life. Under very cold
conditions (-4 °F / -20 °C and below), the battery life will be
shortened. To improve the battery performance in very cold
conditions, consider carrying a fully charged, spare battery in a
warm place (for instance, keeping them inside your coat). The unit
is designed for battery replacement to be easily done.
