For a Wi-Fi connection        - SSID of Wi-Fi UDP NMEA or GDL90 data server (Access Point) ;
For a Bluetooth connection - advertised 'Name' of a Bluetooth device you want to connect to.

Typically, the "server" is one of SoftRF Editions. But other sources, such as SkyEcho, PilotAware, Stratux or similar equipment, should also suffice.

For a Wi-Fi connection        - Wi-Fi AP PSK key ;
For a Bluetooth connection - 'Pin' of the Bluetooth device mentioned above. ³

³ - only Bluetooth 'Simple Pairing' (no key) method is currently supported.

⁴ - this option is currently applicable for Badge Edition only.

An option to choose from two different display views.
Depending on your SkyView hardware, you can change the view in runtime by pressing MODE button.
If your hardware does not have the control button - this view is fixed throughout entire session.

     radar   - radar-alike view. "Scale" navbox gives a value of full span ;
     text     - plain text representation of traffic information .

     CoG Up    - your aircraft's course over the ground is up ;
     North Up - GNSS North is up .

Initial value of radar view's zoom level (scale factor).
Depending on your SkyView hardware, you can change the zoom level in runtime by using UP and DOWN buttons.
If your hardware does not have control buttons - this zoom level is fixed throughout entire session.

Your preferable database for decoding unique aircraft's ID code.
This option makes sense only when you've inserted proper memory card in SkyView's micro SD slot.

     auto          - selection is to be made based upon aircraft's NMEA "ID type" value (when available) .
     FlarmNet
     GliderNet
     ICAO ⁵

⁵ - OpenSky aircraft database

When an aircraft's record will be found, "Text view" will show text identification of this aircraft.
You can choose what particular field of the record will be displayed there.
If no any records found - hexadecimal ID value will be shown.

     registration      - registration number of this aircraft ;
     tail/CN             - tail / competition number (when available) ;
     make & model - make and model of the aircraft (when available) .

Voice of audio traffic alerts.
This option makes sense only when you've inserted proper memory card in SkyView's micro SD slot.

     off       - no voice traffic alerts ;
     voice 1 - Male voice ;
     voice 2 - Female voice ;
     voice 3 - Female voice (allegro) .

Periodic full e-Paper screen refresh. Typically takes 1-2 seconds.
It helps to remove residual traces of previous information, so-called 'ghosts'.
'Ghosts' are known to be temperature and UV dependent.

     off                - do not apply this full screen refresh ;
     2 minutes    - enforce full screen refresh every 2 minutes (counter against heavy 'ghosting' effect);
     5 minutes    - enforce full screen refresh every 5 minutes ;
     10 minutes   - enforce full screen refresh every 10 minutes (little or no 'ghosting') .

     off                                           - do not apply any filters ;
     by Altitude (± 500 meters)    - process air traffic that is not higher and not lower than 500 meters relative to your aircraft's altitude .

     Disabled                 - do not use any of power saving methods ;
     WiFi OFF (10 min.) - turn SkyView Wi-Fi AP off in 10 minutes after last client has closed it's connection .

Team Id is a 6-digit hexadecimal unique identifier of your team member's device ( SoftRF, ICAO, FLARM, Skytraxx, OGN, PAW, etc ...)
SkyView will depict this team member on the Radar screen in a different manner.

     Example (traffic is above your aircraft):

ATTENTION: 'Team member' may become forced out from the screen by any traffic that impose a higher treat of mid-air collision.
