CONFIGURING THE GPS
WAAS/EGNOS is a network of ground stations that monitor satellite data to augment the accuracy of
navigation data. The GPS on the Cycle Trainer uses WAAS/EGNOS technology to provide navigational
pinpointingwithinabout3meters,whileastandardsatellitex(withoutWAAS/EGNOS)isaccuratewithin
about 15 meters.
Getting a satellite fix can take longer when WAAS/EGNOS is enabled. You can turn the WAAS/EGNOS feature
off to shorten the time required to acquire satellite fixes, but at a potential reduction of accuracy.
You can also turn off the GPS entirely. You may want to do this to conserve battery life during periods when
you are not recording rides.

You can view the strength of the GPS satellite fix. The more solid bars appear on the left side, the stronger the
fix.
There is also a message at the top of the screen that summarizes the strength of the fix:
