4 Operation

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. When in Normal operation mode, the logger is ready for recording flights.
The mode in which the NANO4 is operating can be determined from the main screen, or LEDs
when the screen is off.
When 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 NANO4 flight recorder.
Press the power button and the NANO4 will 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 the version of the firmware. The NANO4 will then resume normal operation mode.

Connect the NANO4 to a computer using a USB cable. It will automatically power on. At
the same time, when the connection is established, you will see the first message “USB
connected”, and later “USB mounted” ... This indicates that the NANO4 flight 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 by pressing on any button.
If the Nano is in data transfer mode, and the USB cable is unplugged, the NANO4 will shut
down.

Connect the NANO4 to NanoPower cable. The NANO4 will then automatically power on, and
after approximately 20 seconds the NANO4 will go into normal operation mode.

The normal operating mode starts with a message “Loading elevations” and “Set
elevation”

When the NANO4 acquires a GPS fix, it will switch to the GPS info page. At any time, the user
can 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 NANO

4

position. The NANO4 has a very sensitive GPS receiver which can sometimes acquire a GPS
satellite signal in a room.

Version 1.09 February, 2018

Page 16 of 56

When in the data transfer mode, if you press any button, 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 render input of names, parameters, etc., as easy as possible. Input
controls can be summarized as:

• Text editor

• Spin controls (Selection control)

• Checkboxes

• Slider control

• Line width control

• Colour selection

• “Hamburger” menus

To move the function from one control to the other, use the up or down buttons. By pressing
the Edit button, it is possible to access to the control that is displayed.

Buttons have dynamically set functions. Pressing a button will give more options. The main
text in the box will perform an action assigned in the context. When you press a button, a row
will appear with the action assigned to that button in that context.

On the main screen, the left button always performs the function of switching between pages.
A short push will cycle the pages in one direction. A longer push will cycle the pages in the
opposite direction. A short push means less than a second, almost instant. A longer push
means a second, not more.

The middle buttons help with target selection by cycling through available targets. The right
button has an EDIT /SELECT or EVENT function, where you can edit/view the currently selected
target.

4.2.1.1 Applying a longer push on the buttons

Page (P): P will cycle the pages in the opposite direction.

Sort (x): X will exit from the menu

Next (P): P will move the cursor back

OK (C): C will cancel the performed action

Ins. (D): D will delete the selected point

with the Ok push button.

4.2.8 Spin control

Using the touch screen, you can increment or decrement selected values. The same action
is possible too with the buttons.

4.3 Normal operation

There are four active pages and one additional page (information page, waypoint page, task
page, setup page, and Flarm radar- if the Flarm is connected). You can read more about all
pages in Ch.5.1. If the screensaver function is enabled, the screen will go off after the set time
period in seconds. When the screen saver is on, the pilot can still see the indicated status of
the NANO4 by monitoring the LED.

4.4 Powering off

Holding the power button will give two options. Lock screen or Power off. Click Power off.

Version 1.09 February, 2018

4.5 Security void

When the security (secret key) is lost at power on, the red light will be blinking, and a “DIGITAL
SIGNATURE FAILED” message will appear on the screen. To continue, press any button. The

Nano will be totally functional, but the flight will not be valid under the IGC rules.

In order to produce the IGC-certified files, the NANO4 flight recorder must be
returned to the dealer or manufacturer for resealing.

4.6 Connecting to a computer

You can connect the NANO4 to a PC if it’s on or off. If it is off, it will connect automatically. In
the case, it is already powered on, the NANO4 will ask you if you want to connect it to a
computer.

If the NANO4 is connected to a computer during flight, and if the user confirms a
USB connection, the flight will be forced to end.

Connect the NANO to a computer using the supplied USB cable or any other standard USB-A
to micro-USB cable. The NANO4 flight computer will be identified automatically and a new
removable storage device will be indicated. The name of the device will be
NANO4_<SERIALNUMBER>.

Open this device to see its content.

If you want a faster charge, then you must connect the NANO4 to a power supply, wait for it
to boot up and then press the button to switch the unit off. In this mode all the NANO4 functions
(GPS, Bluetooth, Memory) are turned off, and this will increase the charging speed.
In this mode the NANO4 can be fully charged in approximately 6 hours. The screen is still on,
but the backlight is off. It is still possible to monitor the level of charge. The level of charge is
also visible via the LED.

Version 1.09 February, 2018

Page 24 of 56

Sometimes it may appear that the NANO4 battery level, when connected to a
charger, looks full. Then, when you disconnect the power, the battery level
drops to 90%. This is normal as the battery level indication is different when the
charger is connected, from when it is disconnected. To really fully charge the
NANO4, please continue charging for a few hours. In the fast charge mode, this
will take less time. Charge current must drop close to 0mA or you will see
indication FULL.

The battery is fully charged, when FULL battery status is displayed. This status
appears, when the current drops below 5mA and the battery voltage is more than

4.20V

4.10 Calibration of battery

One can calibrate the battery in the following way.

1. The NANO

4

must be fully charged

2. The NANO

4

is fully charged, when the charge current drops below 5mA, or there is a

message FULL

3. Disconnect the supply cable and leave the NANO

4

running until it shuts down due to an

empty battery

To be sure, that the NANO4 is really in discharge mode, the Battery Status row of
the INFO page text will show “DIP”, which means Discharge in Progress.

One can increase the speed of the discharge cycle, if one turns on the Bluetooth
module, sets up brightness of LCD to maximum, and turns off the screen fade.

After this procedure, the NANO4 has measured its battery capacity and with the next charge,
the indication will be more accurate.

The calibration of the battery is performed during the production of the NANO4. In case that
calibration data is wrong, a calibration cycle is necessary for a correct indication of the charge
level.

If the charge level does not show a correct value, compared to the battery voltage,
it is necessary to perform a battery calibration cycle. Example: Charge level: 99%
and measured voltage 3.6V.

4.11 Storing the Nano

4

The NANO4 must be stored in a dry environment, with a temperature lower than 25°C (77° F).
If you do not intend to use the NANO4 for an extended time, it is recommended that you
charge the battery to 50% beforehand.

The NANO4 and the BATTERY have protection circuits which protect the battery from being
overcharged or overly discharged. If you store the NANO4 with an empty or near empty
battery, eventually the battery will be discharged so much that it will not be possible to charge
it again.

Version 1.09 February, 2018

Page 25 of 56

4.12 Replacing the battery

A user cannot replace the battery in the NANO4. The replacement of the battery can be done
only by an authorized dealer. When someone opens the NANO4 housing, the digital signature
will be lost and flights will not be signed any more. A reseal by an authorized dealer is
necessary.

Version 1.09 February, 2018

5.1 Tree structure

The NANO4 has 5 modes, Info, Flarm (if Flarm is connected), Waypoint, Task and Setup mode.
Info mode has two subpages, where you will find all the necessary information about the
status of the NANO4.

Info

Flarm

Waypoint

Task

Setup

5.2 Main navigation screen description

The main navigation screen consists of a map with coloured Airspace, Waypoints with names
or Task (depending on which page you are looking at), Vario tape (optional) on the left and
status bar on the top.
The vario tape and vario dynamics can be configured in the Setup-Hardware-Vario menu. If
you don’t want to see the vario tape, you can switch it off.
The status line indicates the status of the GPS, indicates the chosen waypoint that you are
navigating to, the status of the Bluetooth device, the battery level and time.

Menu buttons appear, when you press any one of the buttons. Each button has its own function
which is described on the button label. The functions of the buttons are mostly related to the
page where you are (Waypoint, Task, Flarm, Info, Setup). If there is no label on the button,
this button has no function.

The battery level can be displayed in two ways, with the classic battery level indicator or a
round progress (circle) with a number inside, which indicates the remaining hours. Outside
progress indicates the percentage of the battery level. When the remaining time is calculated
to be less than 1 hour, the indication becomes red, and the inside number indicates the
remaining minutes, the outer ring shows the progress for the last hour (60 minutes).

When the battery is charging, the indication is as follows: the inside symbol indicates charging,
the outer ring is the percentage of the charge.
The accuracy of the battery life measurement depends on how accurate the battery capacity
has been measured. One can read more about battery calibration in chapter:Napaka! Vira
sklicevanja ni bilo mogoče najti.. At the top centre of the map there is an “off course”
(steering course) indicator, which helps the pilot to fly in the right direction.

At the bottom of the map screen, there are four navboxes, which the user can use. With a
long press on the nav box, the user can select many navbox options.

5.3 Locked screen

You can unlock the screen by sliding your finger over it.

On the locked screen there is an information about the flight recorder status, the GPS status,

Page 35 of 56

5.8.5 Warnings

In this menu, the pilot can setup Altitude warnings, Flarm warnings and their conditions.
Flarm warnings are classified into three levels (See Flarm manual for details on
www.flarm.com)

• First level (Low) approximately 18 seconds before a predicted collision

• Second level (Important) approximately 13 seconds before a predicted collision

• Third level (Urgent) approximately 8 seconds before a predicted collision.

The Flarm timeout defines the time, when the user will not get a Flarm warning after
dismissing the Flarm warning of a particular Flarm object.

5.8.6 Obs. Zones

This menu defines the default observation zone geometry. One can choose the following:
start zone, turn point zone and finish zone.

Version 1.09 February, 2018

Page 36 of 56

Each type of observation zone is defined with two angles, two radii and a mean bearing
(Angle12). These parameters enable the creation of any known zone geometry separately
for start, turn point and finish.

When using parameters in the zone dialogue, it is possible to describe all types of observation
zones. Angle12 defines the orientation of the observation zone. Available values for
Direction are:

• Symmetric: this is the most common selection for turn point.

• Fixed: this is mostly used for assigned areas.

• Next: this will move the observation zone in the direction of the outgoing leg. One usually

uses this option for the start.

• Prev: this will move the zone in the direction of the incoming leg. It is usually used for the

finish.

• Start: this always moves the sector towards the start.

If the Line checkbox is checked the sector will become a line type of observation zone. The
Radius 1 parameter describes half of width of line length. Use the UP/DOWN arrow buttons
to increase or decrease radius for step 0.1. A longer push will increase/decrease it up to 5.0.
If Line is not checked the Angle1 parameter will define the basic shape of the observation
zone. A value of 180° means that the zone is a cylinder whereas 45° is the classical FAI sector.
Use the Up/Down buttons to select the right angle.
Angle2 and Radius2 are used for more complex observation zone setups.
When changing observation zone parameters, the screen is automatically updated to display
the new zone.

5.8.7 Hardware

There are five sub items in the hardware menu:

• Vario

• Enl

• Communication

• Sounds

• Battery

5.8.7.1 Vario

The vario submenu allows you to adjust the Vario filters for the Vario needle and the vario
sound, the time constant for average vario and vario tape range.

A higher number at the vario filters means a more damped vario signal.

5.8.7.2 Communication

Version 1.09 February, 2018

Page 38 of 56

In the communication menu, you can enable or disable the Bluetooth device, enable or
disable the NMEA output on the USB port, and the baud rate for external serial interface.
"Communication" enables you to set the way the NANO4 will communicate with the Flarm.
"Target data NMEA” enables you can use NMEA data transmission (GPRMB and LXVTARG) to
other external GPS devices (Oudie, PDA’s, Smart phones...). "Target data source" enables the
NANO4 to communicate all information about the current target, depending on which page you
are (Task or Waypoint). The "AUTO option" automatically detects the page mode (whether
you are in Task or Waypoint page) and sends information about your current target.

5.8.7.3 ENL

This page is just for monitoring the engine noise level ENL. MOP (means of propulsion) is
provided to detect noises produced from JET engines.

How to use the Nano4 as a MOP recorder. Please read the IGC approval for the
Nano4.

5.8.7.4 Battery health

You can see the voltage of the battery. It is typically between 3,5V and 4,2V. Current
depends on the power consumption (LCD brightness, BT, Wi-Fi) and the voltage of battery.
Health can be described as:

- Excellent

- Good

- Bad

- Contact service (that may indicate end of the life of the battery).

Version 1.09 February, 2018

Page 39 of 56

5.8.7.5 Sounds

In this menu, you can adjust various setting for sounds. The Volume of the vario sound, the
enabling of system sounds and the enabling of vario sounds. From version 1.5, there is
also a sound setting for Flarm warning.

The vario volume can also be adjusted by using side buttons, but only in the GPS
info page.

5.8.8 Flarm

If a Flarm is detected, the user can make some configuration setting changes on the Flarm
and get some Flarm status information.

5.8.9 Files

It is here that a pilot can select Airspace and waypoints files. The NANO4 supports CUP file
format for waypoints, and CUB file format for airspace. There is no limitation in file size or

Version 1.09 February, 2018

Page 40 of 56

number of waypoints, but by reducing the size of the airspace area or number of waypoints,
one will improve the performance of the NANO.

In the same section, you can convert all IGC files loaded on the NANO4 to KML file format.
You can also load FlarmNet data in this section. It is useful only if the Flarm is connected to
the NANO

4

The Waypoint CUP file is limited to a maximum 1Mbyte size
The Airspace CUB file is limited to a maximum 5Mbytes size
The Flarm net FLN file is limited to a maximum 5Mbytes size

5.8.10 Units

In this menu, one can set the units for speeds, distances, altitudes…

5.8.11 Logbook

All flights recorded by the NANO4 are stored and sorted by date here. The user can find date,
take-off landing times, as well as the duration of the flight. Use the two middle buttons to
navigate through the list. A longer push on these buttons will get you faster to the first, or
last, flight recorded.

5.8.12 Polar & Glider

The Polar and Glider section allows you to load and edit a set of parameters for the polar of
your glider. You can select from a pre-defined list of nearly every common glider or make
your own polar.

Select a Glider from the List: it is an alphabetical list of all the common gliders and
associated polar data. All glider data will be copied from the chosen polar.

Version 1.09 February, 2018

Page 41 of 56

You can modify the polar by changing coefficients a, b and c. A polar is defined as a quadratic
equation with the parameters a, b, and c.
Use the SeeYou program (Tools->Polar) to calculate coefficients a, b and c for a given glider’s
polar. The program requires three sink points entered at selected speeds (e.g.: 100 km/h,
130 km/h, and 150 km/h). The program will calculate the values of a, b and c, which should
be noted and entered into the NANO4.

• Class: options for Touring, Ultralight, World, Twin-seater, Club, 18-meter, 15-meter,

Open, Standard and Unknown are available.

• A, b, c: options can be adjusted or entered for a non-listed glider.

• Reference load (wing loading) value represents the value at which the polar was

measured.

• Reference weight corresponds to the weight value at which the polar was measured.

• Maximum take-off weight is the maximum take-off weight allowed for the glider.

It is not used in the calculation; it is just a reminder to the pilot of the maximum take­off weight. Empty weight is weight of the glider without the pilot and ballast.

• Pilot weight is the weight of the pilot with a parachute and some baggage.

• Co Pilot Weight is the weight of the co-pilot with a parachute and some baggage.

5.8.13 Wind

In this section, the pilot can define a wind calculation method. Select Manual to manually
adjust wind speed and wind course. In the automatic mode, this will be done automatically
by the NANO4 based on GPS data.

The pilot can enter manually wind by sliding on the lower part of the screen
(arrow).

7.1.3 Setting MC

By touching the Mc value, the user can access the following screen.

On this screen Mc, Ballast and bugs can be adjusted. At same time, a calculated final glide
and speed are displayed on the lower part of the screen.

If buttons are used for switching between MC, BAL and Bugs, the left button
indicates, what will be selected by pressing on that button. The active slider is
white, others are in a gray colour.

7.1.4 Declaration and editing of a task

In the Task page, the pilot can enter or edit the task, which will then be automatically declared
when he leaves this page. One can load waypoints into a task from the active waypoint file.

A Task can be entered in a very simple way. In the task page, one can press the edit button.
Using the up or down button, one can highlight an existing waypoint or an empty space, and
then set a new waypoint. By pressing the Ins. (insert) button one can start browsing through
all of the waypoints in the selected CUP file.
Selecting from a list of waypoints is very intuitive. The NANO4 will offer the pilot a choice of
the sole characters that are available from the available list of waypoints names. Using the
button >> one can move to the next character (right), the red part of the label B indicates
one space back or, using a longer push of the button, one character to the left... A similar

Version 1.09 February, 2018

Page 48 of 56

function is used for the OK button, where one can confirm a selected waypoint, or cancel the
selection of a waypoint using the C. The previous waypoint will then be selected.

When one is back in the Task menu, one can Insert or delete D waypoint.

To

insert

a waypoint, the pilot applies a short push Ins. And to

delete

a waypoint,

he depresses and holds down the D button for about (not more than) a second.

Each waypoint can have a custom zone or area applied. These areas can be modified by
pressing the Zone button.

Version 1.09 February, 2018

Page 49 of 56

7.2 On a PC with NanoConfig for Windows

Use the NanoConfig program to configure the NANO4. Using this program, a flight declaration
can be uploaded or various parameters can be modified... The NanoConfig program consists
of two major screens. A flight declaration screen and a settings screen.

You may toggle between these two screens by pressing the Declaration or Settings buttons
in the upper left corner of the NanoConfig program.
Press the OK button to confirm the changes and exit from the program. Press Cancel to
abandon changes and exit without saving data.

It is important to run the NanoConfig program directly from the NANO4. Do not
copy the NanoConfig program to another location, as the settings and declarations
will not be written properly to the NANO4.

The version of the program is written in the lower left corner of the NanoConfig window. When
requesting support from LXNAV or reporting a bug, please always include the version of the
program in your email.

All NANO4 configuration variables are stored in the SYSTEM folder of the NANO4 in
a file named “system.ini”. It is strongly recommended that you do not modify this
file yourself. If you need more information about the “system.ini” file, please
contact us.

NanoConfig for OSX is also available. For more info, please
[e-mail]

7.2.1 Using the NanoConfig program

Run the NanoConfig program and go to the declaration screen. The declaration screen is split
into two groups. Pilot and glider related information is in the top group, and the task
declaration is in the bottom group.

7.2.2 Changing parameters with NanoConfig

Run the NanoConfig program and go to the settings screen. The settings screen is split into
two sections. Settings dedicated to the NANO4and settings for NanoConfig.

Parameters for the NANO4 include a recording interval, a NMEA output and a Bluetooth enable
setting.

In NanoConfig you can change the distance units used in the task declaration and the lat/long
format.

7.2.2.1 Flight recording interval

The flight recording interval is set to one second by default. It is recommended that you keep
this setting. Even with the recording interval set to one second, the NANO4 is capable of storing
approximately 28000hours of flight. Having a recording interval of one second will allow you
to do more accurate post-flight analysis, and it increases the probability of obtaining a data
point in the observation zone.

If you wish to change these settings, use the up/down arrow or type a new value.

7.2.2.2 Automatically finish flight

If this option is enabled, the flight will automatically finish and be digitally signed once
conditions for finishing the flight are met. The NANO4 must fulfil the following conditions for
30 seconds. GPS status is ok, ground speed is below 4m/s, vertical speed is within 0.2m/s,
and altitude is below 3000m.

7.2.2.3 Start recording on power on

If this option is enabled, recording of a new flight will automatically start when the NANO4 is
powered on. If this option is disabled the NANO4 will start recording when vertical speed is
above 1m/s, and the ground speed is above 8m/s. This option is most useful for paragliders.

When this option is enabled, the Automatic finish option is ignored.

Version 1.09 February, 2018

Page 52 of 56

7.2.2.4 Automatically turn off Nano4, when a flight ends

This option is very useful for the NANO,4 when it is installed more or less permanently into the
glider. If this option is enabled, the NANO4 will automatically switch off 30 minutes after the
flight is finished.

7.2.2.5 Bluetooth

Check the Enable Bluetooth checkbox if you want to turn it on. By default, Bluetooth is
disabled.

When Bluetooth is enabled, the NANO4 will consume more power and the total
endurance of a new and charged battery will be reduced to approximately 14
hours.

7.2.2.6 NMEA output

Check Enable NMEA output to output NMEA data. The NANO4 will transmit the following
NMEA sentences GPGGA; GPRMC, LXWP0 every second and LXWP1 once per minute.
NMEA can be output to either the serial interface or Bluetooth, but not to both simultaneously.
Change the NMEA baud rate, if you want to output NMEA at different baud rates.

7.3 Using Bluetooth or serial interface

One can also upload flight declarations using the serial interface or Bluetooth (See chapter

7.4.1 for Bluetooth pairing). The NANO4 must be running in normal operating mode.

When connecting through the serial interface, one should use the same baud
rate, as it is set for NMEA output on the NANO4.
When connected through Bluetooth baud rates are not important.

Please refer to the manual for the software used to upload flight declarations. (E.g. SeeYou
Mobile)

parameters, edit pilot and glider information, edit the declaration, and transfer flights from the
NANO4 to a smart phone.

NanoConfig consists of five tabs: Main, Logbook, Pilot, Task and Settings.

7.4.1 Connecting and pairing the NANO

4

When you run the NanoConfig on a smart phone, the program will first ask you to turn on
Bluetooth, if it’s not already turned on.
Over the menu button one can access the scan function, which will scan for Bluetooth devices.
If the NANO4 is turned on and Bluetooth functionality in the NANO4 is enabled, it will appear
on the scanned list. Choose Nano. The first time one does it, it will be necessary to pair the
NANO4 and the Smart Phone together. Read more about pairing in Ch.4.9.

7.4.2 Main page

On the main tab, information about the NANO4 and its GPS status are shown/displayed.

7.4.3 Downloading flights

The first time one accesses this tab, the NanoConfig will automatically start reading flights
from the connected NANO4. Downloading always starts from the most recent to the oldest
flight. If you have a lot of flights in the NANO4’s memory, the transfer of the logbook can be
interrupted with the BACK button.

After the downloading of the logbook data is finished, a short pression on the desired flight
will start the download process. If the flight size is large, the download may take more than
one minute. Flights are downloaded into the NanoConfig folder. With a longer push on the
flight, one can share the downloaded flight with other applications installed on a smart phone
(Gmail, SeeYou, OLC (not available), Google Docs, Facebook).

7.4.4 Editing pilot info

one can load the Pilot tab to edit information about the glider and its crew.

7.4.5 Editing task for declaration

Editing the task is very simple. First, it is necessary to choose a waypoint file in the CUP
(SeeYou) format. To select the CUP file, use the MENU button. On some devices you must
press for a long time to menu button. Press the Add waypoint button to add the waypoint to
the last position. A long pression on the waypoint will give you an option to insert a waypoint.
On the right-hand side of waypoint name, there is a trash box. Press the trash box to delete
the waypoint from the list. After a task has been entered, it can be transferred to the NANO3
by pressing the Write button.

7.4.6 Configuring NANO

In this tab one can configure the recording interval, automatic power off, and NMEA
settings.
