3.4 Four push buttons
Nano
3
has four push buttons, which have a dynamic function.
The function of each push button is described on the blue label adjacent to the button. A
label can have two options with the second option coloured red on the label. This indicates
that the button has two functions. The blue option is operated with a short press and the red
option with a long press. For labels with two options, the second option is typicaly the
oposit function of the first option. e.g. Next/Previous, Insert/Delete, Ok/Cancel,
forward/backward.
3.5 LEDs
On the left side there are five LEDs; three green, one blue and one red. The LEDs show the
status of the NANO

NANO

is powered on. The second LED blinks when the GPS status is ok. The third LED
blinks when the recording of a flight is started. The fourth blue LED blinks when the
Bluetooth module is switched on.
