2) To turn on your GPX, press the Menu button. To reboot the GPX, press all 4 buttons
simultaneously.
3) For best GPS reception, the GPX's antenna should be mounted where it is least obstructed and
has the best possible view of the sky. If possible, the flat side of the antenna module should be
mounted pointing down, with the "bumped" portion pointing up toward the sky.
4) GPS satellite signal quality is displayed in thebox in the middle of the main screen. On first
start up, or when not used for 2 or more hours, it may take the GPX a few minutes to locate
enough satellites to work correctly. It needs a minimum of at least 5 satellites and an EHPE
(estimated horizontal position error) of less than 3.00 in order to operate correctly. The more
satellites and lower EHPE, the better the GPX's reception will be. Aslo, the dbHz value is an
indication of the quality of the satellite reception. Larger numbers are better. Overall, these
numbers are combined to compute a "GPS Quality" percentage which is displayed in that box.
5) Now the GPX is ready to race! Out of the box, your GPX is configured for circuit racing (closed
course) and will automatically start operation when you exceed 35 mph (56 kph) and stop when
speed is less than 5 mph (8 kph). Once you have run two laps, the GPX recognizes the shape of
the track and will ask you to enter a name once your session is over. Using the arrow keys, you
can select characters to name the track. TO move to the next character, press Select. Once the
name is entered, press Menu to store the track. The next time you race that circuit again, GPX will
automatically recognize it.
6) From the main screen, press the Right arrow button to see the summary of your last session.
(Press Left or Right to move through your various sessions.) By pressing Select, you can see
information collected on your laps. Use the Left and Right arrows to view different laps of that
session. Press Select while viewing any lap to view the track map. To return to the main screen,
press Menu repeatedly.
7) Now it's time to customize! From the main screen, press Menu and use the arrows to navigate
through GPX's menus. When you find the menu you are interested in, press Select to begin
customizing. Use the Menu button at any time to go back.

Important Notes
Battery
If you will not be using the GPX for an extended period of time (more than about 2 months), you
should charge or discharge the battery to approximately 40%-50% charge, and then open up the
GPX case (4 screws) and disconnect the battery (carefully pulling on the red and black wires).
Long periods of non-use can affect the useful life of the battery if it is left connected to the GPX
circuit board.
