Introduction

Using a GPS Training Device

Your Timex Ironman GPS watch features a built-in GPS. Once connected and receiving signal
from the constellation of GPS satellites, your GPS provides distance, speed/pace and elevation
information. For best performance, wear the watch on your wrist with the display facing the open
sky.

Best Practices

To get the best performance from your TIMEX IRONMAN GPS watch, it is suggested that you
download and use the Timex Connect Computer Application:
Your TIMEX IRONMAN GPS watch uses satellite data (long-term satellite orbit prediction),
downloaded to your watch, to give:

Faster GPS fix

More accurate distance and pace / speed data

Improved battery life
GPS data (also known as ephemeris data) is contained in a file that is automatically
downloaded to your Timex Watch whenever you connect to the computer application. A valid
internet connection is all that is required. This GPS data is valid for up to four (4) days,
therefore, Timex recommends connecting your watch to the computer application daily to
charge your watch, upload your workout files and obtain current GPS ephemeris data. These
regular updates will ensure your GPS watch is running optimally.
NOTE: If you are using a wall adapter to charge your watch, the GPS ephemeris will not be
downloaded to your watch. You must connect to the Timex Connect computer application to
receive current GPS data files used by the watch.
