4Operation
There are two modes of operation: Data transfer mode and Normal operation mode.
When in the data transfer mode, flights can be downloaded and the NanoConfig program
can be run. Normal operation mode is when the logger is ready for recording flights.
The mode in which the NANO4is operating can be determined from the main screen or
LEDs, when the screen is off.
In data transfer mode, there will be a message on the screen “USB connected”, whereas
in the normal operation mode, the screen will display data only.
4.1 Powering on
There are three ways to power on the NANO4flight recorder.
Press power button and the NANO4will power on. It will go directly to normal operation
mode. On start-up, a splash screen will appear with information containing the Serial number
and version of firmware. The NANO4will then go into normal operation mode.
Connect the NANO4to a computer using a USB cable. It will automatically power. At
the same time you will see the first message “USB connected” and later “USB mounted”,
when the connection is established. This indicates that the NANO4flight recorder is in data
transfer mode. You may now run the NanoConfig program or copy flights using standard
methods for copying files. You can exit to normal operation mode with pressing to any
button. If Nano is in data transfer mode and USB cable is unplugged, NANO4will shut down.
Connect the NANO4to NanoPower cable. The NANO4will then automatically power on
and after approximately 20seconds the NANO4will go into normal operation mode.
Normal operating mode starts with a message “Loading elevations” and “Set elevation”
When the NANO4acquires a GPS fix, it will switch to the GPS info page. The user can at any
time, cancel the acquiring page by pressing any button. Acquiring a GPS fix may take
between a few seconds and a few minutes, depending on the satellite constellation and the
NANO4 position. The NANO4 has a very sensitive GPS receiver which can sometimes acquire a
GPS satellite signal in a room.

Version 1.05 May 2017
Page 16 of 54
If you press any button, when in the data transfer mode, the NANO4 will revert to
normal operation mode
4.2 User Input
The NANO4 user interface consists of many dialogues, which have different input controls.
They are designed to make input of names, parameters, etc., as easy as possible. Input
controls can be summarized as:
