User Manual

Mechanical shock
The device is designed to resist damage for drops up to 4 ft (1.22 meters).
However, you should protect the display from impact, pressure, or abrasive
substances that can scratch it or crack it. The device should not be dropped
unnecessarily.

Environmental considerations
The device’s rugged design allows you to run your device in harsh outdoor
environments. Here are some considerations that will help you get the most
out of your device when working in very wet, hot or cold conditions.
Water: This device is designed to IP65 (grey units) or IP68 (yellow units).
IPx5 is defined as resistant to driving rain and water spray. IPx8 is
defined as resistant to submersion in water up to 1 meter deep for up to 2
hours.
WARNING: Removal of the back case screws could cause leakage and
will void your warranty.
NOTE: Although an optional accessory for the port cover is available and
the audio jack has a protective cover, these are not required to maintain the
seal 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
+144 °F (-30 °C to +60 °C). Although the device is designed to be rugged,
do not leave it in direct sunlight in excessive heat or in a vehicle in the
sunlight for extended periods as the internal temperature may exceed the
operating or storage temperature limits.
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 capacity. Under very cold
conditions (-4 °F / -20°C and below), the battery capacity is noticeably
reduced. To improve the battery performance in very cold conditions,
consider increasing the load on the battery, such as by adjusting the
backlight to full brightness. Increasing the battery load causes the battery
to generate heat, thus warming the battery and improving the performance.
There are limits to how hard to push the battery before you reduce the
run-time instead of increasing it.
