displayed. You may find that positioning the GPX in a different spot on your vehicle may have an
effect on signal quality. Generally, the more “open” the GPX is to the sky, the better the
reception.
Also, as a result of the constant motion of the GPS satellites, you may find that, at the same track,
on different days, or even within the same day, you may find significant differences in the quality
of signal.
The GPX uses a sensitive internal antenna (mounted inside the GPX enclosure) as standard. If you
wish to improve your GPS signal quality pick-up, you may order an auxillary external antenna with
magnetic mount which can be positioned up to 10 feet from the GPX unit, for improved reception
(for example, it may be mounted on the roof of a racing car, or on the tail section of a
motorcycle).
The GPX requires a minimum quality of GPS signal before it can be used. It must have at least 4
satellites in view, and the EHPE (estimated horizontal position error) must be less than 5.00.

Troubleshooting

If the GPX appears be not responding, you can press all 4 buttons simultaneously to reset the
device.
Only perform the 4-button reset if the GPX is not responding. If
the GPX is in the middle of a file operation, there is a possibility
that the file system could become corrupt.
·
You may need to adjust the LCD contrast for optimal display under conditions of very high and
very low ambient temperatures
·
If you get a warning about "file system full" or "low on directory space", you need to clear out
some sessions in your GPX before continuing. If you want to save those sessions before
deleting them, connect up to GPStudio and download those sessions to your PC. After that,
using the
File Maintenance
menu option, select one of the delete options and delete some or
all sessions to free up some space.
·
When you connect the GPX to your PC, it may take up to 10 seconds before you hear the "da-
ding" sound indicating that the GPX is properly connected. This is normal.

Occasionally when you connect the GPX to the PC, you may not get a "da-ding" sound, or you
