Note: Use Manual-Altitude (MAN-ALT) for one-time, manual re-
calibrations. Use Home Altitude and Base Altitude 1,2,3 to store
altitude reference points that will be used multiple times.
Note: If you have already entered a reference point, you can
quickly select that reference point and hold STOP/RESET to
quickly calibrate.
INDIGLO ® NIGHT-LIGHT
In any mode, when you press the INDIGLO ® button, the watch face will light
up for easier viewing. You can also activate Night-Mode ® if you press and
hold the INDIGLO ® button until you hear a beep. The Night-Mode ® feature is
a very useful feature in low light conditions because it allows you to press
any button to light the watch for 2 to 3 seconds. Once activated, the Night-
Mode
® feature stays active for 7 to 8 hours. If you want to deactivate Night-
Mode ® before 7 to 8 hours have elapsed, press and hold the INDIGLO ®
button until you hear a beep.
ATTENTION: Sudden changes in barometric pressure can
impact your altimeter reading. If possible, re-calibrate to a
known altitude when drastic pressure changes occur.
