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. 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 (yellow units) or IP68 (grey 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.
