Before using the board for the first time, the user should check that it has not been visibly
damaged during the shipment, and that no components are unplugged or missing. When
the board is extracted from its plastic bag, check that no component remains in the bag.
The main components to verify are:
1.
25 MHz crystal (X4) which may have been removed by a shock from its socket.
2. The microSD card which may have been ejected from the connector CN17 (right side
of the board) and CN30 (bottom side).
Caution:
There is a risk of explosion if the battery is replaced by an incorrect one. According to the
instructions, make sure to dispose of used batteries.
