Cleaning Your BTIR
When removing mud or other debris from the BTIR, ensure that the USB protective cap is installed, then
use a damp cloth for cleaning and completely dry the BTIR before use.

Maintaining your Battery Pack
6.1 Battery
Usage
The BTIR comes with a rechargeable Lithium Ion battery pack. The battery life between charges varies
with usage but typically allows up to 12 hours of operational use. The Battery is replaceable in the field but
it is recommended that the entire unit be returned for quality inspection and proper disposal of the battery.
6.2
Charging the Battery
The lithium-ion battery can provide between 300-500 charge/discharge cycles. The lithium-ion battery is
different from most other rechargeable batteries because charging from a partially charged battery keeps
the battery in good condition. Lithium-ion batteries should be charged early and often. Fully discharging
the lithium-ion battery should be avoided whenever possible. For most users, charging the battery at the
end of each work day is adequate for battery care. The lithium-ion battery pack typically lasts about 2-3
years, but potentially longer if cared for properly. Li-ion batteries should be kept cool. They should not be
subjected to freezing temperatures. Aging will occur much faster at high temperatures (such as a hot car)
and will reduce the life of your battery.
•
Only charge the battery in the BTIR through the USB port.
•
Do not use or charge the battery close to a fire or inside a car in which the temperature may exceed
140°F (60°C).
•
Stop charging the battery if charging is not completed within the specified time.
•
The battery can be fully charged within a 32°F(0°C) to 114°F(45°C) temperature range. The
charging circuit will be disabled or charging will be reduced outside of this temperature range.
•
Use the battery only in the specified equipment.
•
Do not charge the battery in a place where static electricity is generated, or let the battery touch
something that is statically charged.
The internal Battery of the BTIR is charged through the USB port. The USB port does not transfer data and
it will not be recognized by a computer. If the USB port of a computer is used for charging, set the power
of the computer port to 500 mA.
If the Car charger is used for charging, plug the charger into an active receptacle, connect the USB cable
to the car charger and then connect the other end of the USB cable to the BTIR. It is not recommended
that the BTIR be charged by the car charger if the vehicle interior will become hot. The charging circuit will
automatically shut down if the BTIR temperature is greater than 140°F (60°C).
6.3 Battery
Warnings
The BTIR has an internal battery. In the event that the battery pack or the battery pack components are
removed from the BTIR care must be taken in the handling of the battery pack or its components.
