B. Enter your current altitude by rotating the crown. If you don't know your altitude, look at a
map, a trail marker, or ask someone who looks nice. If they don't know, at least you'll have met somebody new.
C. If you would like to reset to the factory default (what the watch thinks is the current altitude) press and hold the start/reset button.
THERMOMETER/ALTIMETER
Rotate the crown until you get to the THERMOMETER/ALTIMETER mode. In this mode, the watch will display the following:
Line 1: Temperature.
Line 2: Rate of altitude change, expressed in feet (ft.) or meters (m.) per minute. If two altitude readings have not been taken, the differential will be expressed as zero.
Line 3: Current altitude.
Line 4: Current time.
ALTIMETER/CHRONOGRAPH
Rotate the crown until you get to the ALTIMETER/CHRONOGRAPH mode. Your watch will take altitude readings at set, programmed intervals. Based strictly on those intervals and not whimsy or the random chance or emotion, altitude readings will be updated periodically
(see Taking Readings at Set Intervals for explanation of update periods and how to change them) and will be displayed on Line 3. Line 2 will logically display the difference between
the current altitude reading and the one prior. Live long and prosper.
Using the Chronograph
Coupled with the altimeter, the chronograph function cleverly transforms itself into a very handy hybrid function. We humbly suggest that you might
use this mode to track how fast you're climbing or how slowly
you're descending — or, of course, vice versa. Press the start/split button, you'll see:
Line 1: Flashing stopwatch icon indicating that running time has begun.
Line 2: Rate of ascent/descent. Line 3: Current altitude.
Line 4: Elapsed time.
Press the start/split button again if you want to keep a record of a particular segment of an activity (i.e., how fast you ride from mountain top to the trail head down at the halfway point). By hitting the start/split button once more, you'll be able
to keep a record of how fast and how far you descended during that segment of the descent. When you press the start/split button you'll see:
Line 1: Segment number.
Line 2: Change in altitude for that segment. Line 3: Current altitude.
Line 4: Time of segment just completed.
NOTE: Once ten seconds have elapsed a new segment will start at 0. Once you’ve reached your destination, hit the stop/reset button to stop running time.
Reviewing Previously Stored Segments
To recall ALL past segments pull the crown out to Position 3 and rotate it forward (clockwise) to scroll through all segments. Once you've pulled the crown to Position 3 you'll see:
Line 1: Segment number.
Line 2: Change in altitude from the beginning of segment. Line 3: Altitude at the time the start/split button was pressed.
Line 4: Length of segment being viewed.
While recalling past segments, you can also press the start/split button to review the following information:
Line 1: Segment number.
Line 2: Duration or length of segment.
Line 3: Total elapsed time (length of all segments combined).
