GPX Pro Manual3

1) Before using your GPX for the first time, it needs to be charged overnight. The supplied USB

cable can be used to charge it from your PC as well as any wall or cigarette lighter charger

designed to connect to a standard mini-USB device. If you connect it to a PC, you may cancel out

the installation if you'd like and the device will still charge.

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 rounded portion pointing up toward the sky.

4) Satellite signal quality is displayed in the lower-left-hand corner 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 at least 4 satellites and an EHPE (estimated

horizontal position error) of less than 5.00 in order to operate correctly. The more satellites and

lower EHPE, the better the GPX's reception will be.

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.

1.2 Circuit Racing Mode

Circuit Racing mode is for tracks on which you run multiple laps – circle tracks, oval tracks, road

racing tracks, etc. There is a start/finish line which you cross multiple times, and detailed lap

information is stored for each lap. Up to 5 split points may be defined.

1.2.1 Basic Operation

Fresh out of the box, the GPX is configured in Circuit Racing mode and is ready to go. Turn on the
