31.3 Charging and storing batteries
All battery types discharge over time when they are not being used. Batteries also
discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long
periods of time, make sure it is fully charged before storing and re-charged at least once
every three months.

WARNING – Charge and use the rechargeable Lithium-ion battery only in strict
accordance with the instructions. Charging or using the battery in unauthorized
equipment can cause an explosion or fire, and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium-ion battery only with a product that is specified to charge it. Be sure
to follow all instructions that are provided with the battery charger.

– Use the battery only for its intended use and according to the instructions in the product
documentation.
The receiver can be powered by its internal battery or by an external power source. If
an external power source is connected, it is used in preference to the internal battery.
When there is no external power source connected, or if the external power supply
fails, the internal battery is used.
The receiver is supplied with two rechargeable Lithium-ion batteries, and a dual
battery charger. The two batteries charge sequentially and take approximately four
hours each to fully charge.
C
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.
