UltraMax GPS mode
UltraMax GPS mode utilizes GPS, motion sensors and proprietary algorithms to extend the battery life without sacrificing too much of the tracking accuracy. For every 120 seconds, the GPS is switched on for 30 seconds. COROS’s Intelligent Stride algorithm along with motion sensors will kick in for the remaining 90 seconds. Every outdoor run and calibrated indoor run improves the Intelligent Stride algorithm and enhances the tracking of your next workout in weak or no GPS signal environment.
To enable the UltraMax GPS mode, please start an outdoor running workout mode such as Run, Trail Run and Hike. Then press and hold the BACK/LAP button to bring up the toolbox menu. Scroll to locate the UltraMax setting and switch it on.
It is recommended to calibrate the compass before using this feature.
