If there is no replaceable battery in the device, only
the green icon of the built-in battery is displayed on
the right.
If the both batteries are fully charged, the replaceable
battery will be preferred to power the device. If the
replaceable battery level is low, the device will switch
to the built-in battery automatically.
When connecting to the external power supply using
the USB port (9), it will switch to the external power
supply automatically. At this time, a lightning charging
icon is displayed above the built-in battery icon on the
right of the display, which indicates that the built-in
battery is being charged.
When the device is in use, it is possible to change the
replaceable battery without powered on. At this time,
it will switch to the internal battery automatically.
Safety Measures
When charging, always use the 5V2A power adapter
compatible with the device. Using any other type of
adapter may cause irreversible damage to the battery
or the adapter itself.
If the device is not in use for a long time, the battery
should be partially charged, not fully charged or
discharged.
Do not charge the device immediately after it is
moved to a warm environment from a cold
environment. Wait for 30 to 40 minutes for
preheating.
If the charger is modified or damaged, do not use it.
The device should be charged at a temperature of
0°C to +40°C. Otherwise, the battery life will be
significantly reduced.
When charging, please do not leave the battery
unattended.
Do not connect the battery to the power supply for
more than 24 hours after it is already fully charged.
It is not recommended to connect third-party devices
that consume more energy than the allowed value.
The device is equipped with a short circuit protection
system, but conditions that may lead to a short circuit
should be avoided.
The recommended operating temperature for the
device is -20°C to +50°C. Do not use the device
beyond this temperature range, or else, it may shorten
the battery life.
When using the device at low temperatures, the
battery capacity decreases. This is normal and not a
defect.
Do not use the device at the temperatures above
50°C – this may decrease the battery’s life.
Keep the battery out of the reach of children.
