tinuous altitude measurement display. Altitude measurement and elapsed
time measurement start automatically.
(2) Switching to the continuous altitude measurement display or fixed duration
altitude measurement display during climbing provides a continuous display
of altitude and elapsed time. Pressing button (B) during altitude measure-
ment switches the display between altitude and barometric pressure.
4. Storing Altitude and Time in Memory at Check Points while Climbing
(1) When button (A) is pressed for at least 2 seconds during the altitude mea-
surement display, “-1-” (point no.) is displayed which represents the first
memo. Data including altitude, barometric pressure and temperature at
that location are stored in memory in the form of an altitude memo.
(2) Press button (A) again to store the time in memory.
(3) A maximum of 6 points can be stored in memory as altitude memos by
repeating steps (1) and (2).
5. Terminating Altitude Measurement after Arriving at the Peak
(1) Stop measurement of elapsed time by pressing button (A) during the alti-
tude measurement display. When desiring to store data at the peak, per-
form the procedure for storing altitude memos in memory (4.-(1),(2)).
(2) Press button (M) for at least 2 seconds to return to the standard mode.
This terminates altitude measurement.

17. Altimeter Applications
The following is an introduction to specific applications of the altimeter of this
watch. Please read the explanations of the uses of each function for further
details regarding the respective operating procedure.
A. Measuring Altitude when Mountain Climbing
1. Deleting the Altitude Memo of the Previous Climb to Store Data of the
Current Climb
(1)
Press button (M) to switch to the altitude memo mode of the standard mode.
(2) Press buttons (A) or (B) to recall the altitude memos of the previous climb.
Necessary data displayed at this time should be recorded in a log.
(3) Simultaneously press buttons (A) and (B) to delete all altitude memos.
2. Ensuring Accurate Altitude Measurement Before Climbing
(1) Press button (M) for 2 seconds or more to switch from the standard mode
to the altitude measurement mode.
(2) Press buttons (A) or (B) during the altitude correction display to align the
altitude displayed on the watch with a display of correct altitude as deter-
mined by triangulation and so forth.
3. Starting Altitude Measurement
(1) Press button (M) during the altitude correction display to switch to the con-
