User's Manual

The X3 is delivered with some power stored in its internal battery.
The battery should however be fully charged for 8-10 hours with the
included power adapter before first use.
WARNING
Using damaged mains cords or chargers, or charging when
moisture is present, can cause electric shock.
CAUTION
Do not use a power adapter other than the one supplied or specified
by FlightScope. If an adapter with incorrect voltage rating is used,
the X3 electronics can be damaged. If an adapter with insufficient
current rating is used, the adapter may overheat and become
damaged.
