Replacing the Battery

To recharge the battery:
Connect the unit to a power outlet using the USB power adapter (fastest
way to charge the battery).
Note: The standard USB ports of a computer cannot power your unit or charge its
battery while the unit is on. If you connect your unit to such a USB port with
the USB cable, the unit will still consume battery power. If the unit is off
when you connect it to the USB port of a computer, its battery could charge,
but slowly.
Note: If you have a vehicle equipped with dedicated USB charging ports, you
could connect your unit to one of these ports to charge the battery. The
actual results will vary with each vehicle. You could also use a certified USB
power bank (portable charger) to charge your unit.
The charge cycle will start and end automatically.
Replacing the Battery
Your unit can be powered either by battery or from an appropriate power
outlet when used with the provided USB power adapter.

period of time, ensure that the battery is charged at around

that the battery is charged at around 50 % of its capacity. Every

you get the optimum performance out of the battery.
