Step 1.
Using the supplied mounting kit, install the antenna in a location with a good view of

the sky. The importance of this step cannot be overstressed, having a good clear
view of the sky and the GNS satellites is a prerequisite in order to obtain good
performance from the unit.

Step 2
Connect one end of the supplied antenna cable to the antenna, and the other end to

the unit's antenna input.
Note: the center conductor of the cable is used to additionally supply the 5V DC
power to the antenna.

Step 3
Connect AC mains input power to the unit using the supplied AC mains cord. Upon

power connection the fault LED will flash at a rapid rate indicating that the unit is
initializing. During this period the unit operating system is being loaded and initial
self tests are being performed. After approximately 30 seconds the front panel will
illuminate and display the main status screen choices.

NOTE: If no key is pressed on the front panel keypad within 10 seconds, the last
selected default screen will be displayed.

To re-display the main status screen choices after a status screen is displayed,
simply press the "MAIN" key.

Selecting the required st atus di s play.
When in the m ain status screen choice display, pressing the keypad

forward/backward arrows will scroll forward/backward respectively through the
status screen choices. Pressing the up/down arrow keys will page up/down through
the status screen choices. Once the required choice is highlighted, pressing enter
will select the highlighted status screen as the new default, and will switch the
display to the selected choice.

Status Display Short Cut Keys
As an alternative to highlighting the required status screen choice, the number of the

required screen can be pressed on the front panel keypad and the required status
screen will be displayed. Similarly, when any of the status screens are being
displayed, pressing a number on the front panel keypad will switch the display to the
status screen represented by the number pressed.
