Appendix Optimizing Battery Life Use premium batteries for optimal performance and maximum battery life. Consider the following suggestions to maximize battery life: Resetting the Foretrex If your Foretrex is locked up, press and hold page and simultaneously until the screen goes blank (about 7 seconds). This does not erase any of your data or settings. • Excessive use of the backlight will significantly decrease battery life. • Select a shorter backlight timeout (page 3). • Turn tones off if not needed. From the main menu, select SETUP > SYSTEM > BEEPER > OFF. • Turn off the compass when it is not being used (Foretrex 401 only). Select SETUP > HEADING > COMPASS > OFF. Clearing User Data NOTICE: This deletes all history and user‑entered information. To clear all user data, press and hold enter on startup until the message appears. 26 Foretrex 301/401 Owner's Manual
