User's Manual

About this user guide
l Depending on the model, the handheld is rated IP65 or IP68, but is not waterproof. Do not
immerse the handheld in water, and be careful not to drop the handheld or subject it to any
strong impact.
l To clean the handheld, use a soft, dampened cloth with either water or a diluted mild
detergent. If a mild detergent is used, ensure all soap residue is removed. Do not use any
chemical cleaners and do not put the device in the dishwasher.
l 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.
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.
l 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 submerson in water up
to 1 meter deep for up to 2 hours.
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
l Temperature range: The operational temperature range is from -22 °F to +140 °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.
Do not attempt to dismantle the device for repair. There are no user-serviceable parts inside. For
service, contact your local dealer.
Battery safety: Lithium-ion polymer batteries are classified by the U. S. Federal Government as non-
hazardous waste and are safe for disposal in the normal municipal waste stream except where
prohibited by local or regional regulations. These batteries contain recyclable materials and are
accepted for recycling.
Note – In the event of a battery failure, return the device to Trimble or an Authorized Service Provider.
Trimble disposes of used batteries in accordance with local regulations.
