1 Battery Saver Backlight - The backlight brightness and timeout settings do not automatically change when Battery Saver is enabled. Users may change the backlight brightness after enabling Battery Saver by selecting Reduce Backlight in the Battery Saver menu. Users may change the backlight timeout through System->Display. Leaving the brightness set to Auto and timeout set to Stays On may result in a reduction in battery life.

2 Following a Course - Each course is unique regarding the number and type of alerts generated. The number of alerts generated by the course will impact battery life. Courses that generate a large number or frequent alerts will consume more battery life than courses with fewer turns or alerts

3 This calculation assumes that daytime riding is done in consistent 75,000 lux conditions. To extend battery life further, see “Tips for Using the Edge 540/840 Solar Device” in the Owner’s Manual. The Solar harvester will always be enabled in the specified temperature range. However, when the battery is at or near 100% the harvester may reduce its power output which may reduce the overall improvement in battery life.

4 The usage of a Garmin Varia™ Rearview Radar with your Edge device may result in an additional reduction in battery life. This potential, additional reduction in battery life will vary depending upon traffic conditions and the number of vehicles in the vicinity of the radar device during operation.
