GPX Pro Manual13

1.2.1 Basic Operation

Unlike Circuit Mode, in Point-to-Point mode, the GPX cannot determine the start and finish for

the race. You must “create” a new track, then define the start and finish point. (And optionally

define split points.)

To “create” the new track, go into the menu system, go to Track Options, then press Select. Using

the arrows, go to Create a new track, and press Select. Enter the name of the new track using

arrows and Select. Press Menu when the name is complete.

Now, physically go to the starting point of the race. On the main screen, make sure you have a

good GPS signal (4 or more satellites, less than 5.00 EHPE). Go into the menu system, go to Track

Options, and using the arrows go to Set start point. Press Select. You will now choose the track

using the arrows (if you only have one point-to-point track in the GPX, it will be shown with no

left or right arrow showing). Press Select on that track. Make sure you are at the starting point,

and press Select. After a few seconds, the GPS information will be recorded, and it will return to

the menu system.

Do the same procedure for the finish of the race by going to Set finish point and following the

same steps.

Do the same if you want to enter any split points for the race. Please note that you do not have to

set the start point before you set the finish point – you may define the start/finish/split points in

any convenient order.

Notice that on the menus, a check mark is displayed next to each point which you have defined:

To start the race, go into the menu system, go to Select

a track to start race, and select the track.

There are two methods to start a point-to-point race --Standing start and Running start. Use

standing start when a race starter starts you. (For standing start, the "start point" of the race is not

actually used -- it assumes you are starting from the correct spot.) For a standing start, the

accelerometers must "zero" themselves, which takes a few seconds when you select the track to

start the race. Zeroing of the accelerometers allows the GPX to determine the precise instant
