Due to reasons such as self-consumption of the battery during transport and storage, it is normal
to have a low or empty battery when using it for the first time, and charging can be done in the following
way.
1) Charge the battery
2) Companion Remote Control
When the battery indicator light of the companion remote control shows that the battery is low,
you should connect the companion remote control to the charger as shown in the figure below:
a) We recommend you to use a 5V/1A USB charger which meets FCC/CE standard.
b) The power indicator light will flash at 1Hz (1 second/time) in charging status and indicate the current
power level.
c) When the power indicator light is all off it means the battery pack is full, please remove the charger to
finish charging.
