NAV Keys

Four keys are used to interact with NAV (see Figure 1.2). In this manual we will call MENU key
(S1), ENTER key (S2), UP key (S3), and DOWN key (S4). Each key has 2 functions depending
on context, whether the device is in flight mode or in menu mode. Additionally the MENU key is
used to power-up the NAV when it is switched off.
In the flight mode Keys S2, S3 and S4 have user configurable functions F1, F2 and F3 that can
allocated in the Menu->Settings->FS Keys (see Section 13.14). When a map object exists on a
page FS Keys definition will be ignored and S3 and S4 will zoom in and out of the map whilst the
S2 will switch page. In menu mode all keys have fixed functions shown by symbols on the keys
namely S3=Up S4=Down, S2=Enter and S1=Back.

Using keys Inside Menu

Changing parameters on the NAV can be performed through the menu. Changing a parameter
involves accessing the menu, selecting an option, and then changing a specific field value. Accessing
the main menu can be done by pressing the MENU key in flight mode. Once in the menu, UP(S3),
and DOWN(S4) keys can be used to scroll up and down through the menu options list. Once the
desired option is selected, the option is highlighted, the ENTER(S2) key should be used to access
the option. Depending on the menu option, a new menu options list, or a data fields list appears.
Pressing the MENU(S1) key takes you back. When accessing data fields the associated menu option
becomes grayed and the respective field data item is highlighted. Using the UP and DOWN keys
changes the value on each field. When the correct value appears pushing the ENTER key moves
to the next field, or in same cases to the next character/digit. Conversely, pushing MENU key
moves to the previous field, or to the next character/digit. If the ENTER key is pushed on the last
field all the data in the selection section is stored and control returns to the configuration menu.
Inversely, if the MENU key is pushed on the first data field the changed settings are ignored and
control is returned to the configuration menu. When setting a data field that involves setting several
characters, e.g. when defining a waypoint name, after defining the desired characters, then pushing
the ENTER key continually for more than 2 seconds will make the cursor jump to the next data
field, or return to the configuration menu if no more data field needs to be set.
