Juno Series User Guide 25
Getting Started 2
Powering the handheld
The Juno series handheld contains a rechargeable Lithium-ion battery.
Note – Charge the battery completely before using the handheld for the first time. If the
battery has been stored for longer than six months, charge it before use. Trimble
recommends charging the battery for four hours to recharge it fully.
Note – Cold temperatures, or using Bluetooth wireless technology or wireless LAN
connectivity, or using the cellular modem consumes additional battery power and so
shortens battery life between charges.
AC adaptor safety

WARNING – To use AC adaptors safely:
– Use only the AC adaptor intended for the Juno series handheld. Using any
other AC adaptor can damage the handheld and may void your warranty. Do not use
the AC adaptor with any other product.
– Make certain that the input voltage on the adaptor matches the voltage and frequency
in your location.
– Make certain that the adaptor has prongs compatible with your outlets.
– Do not use the AC adaptor in wet outdoor areas; it is designed for indoor use only.
– Unplug the AC adaptor from power when not in use.
– Do not short the output connector.
– Be aware that there are no user-serviceable parts in this product.
– If the AC adaptor becomes damaged, replace it with a new Trimble AC adaptor.
Battery safety

WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of damage include,
but are not limited to, discoloration, warping, and leaking battery fluid.
– Do not store or leave your device near a heat source such as near a fireplace or other
heat-generating appliance, or otherwise expose it to temperatures in excess of 70 °C
(158 °F) such as on a vehicle dashboard. When heated to excessive temperatures, battery
cells could explode or vent, posing a risk of fire.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.

WARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be
leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or
property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid.
– If battery fluid gets into your eyes, immediately rinse your eyes with clean water and
seek medical attention. Do not rub your eyes!
– If battery fluid gets onto your skin or clothing, immediately use clean water to wash off
the battery fluid.
