（8） How to display recording climbing data
・ P ress Button Ⓔ in the REC ON mode.
T he average climbing speed up to the present, accumulated altitude, and the altitude
and time when REC is turned ON are displayed.
※ W hen the climbing speed or accumulated altitude is displayed, guidance ( ▲ ) on the left side
indicates whether they are ascending or descending data in animation.

（9）About data recording (REC) function
・ T he following data are recorded in the REC ON mode.
■ Recording date and time required
■ Average climbing speed (Ascending/Descending)
・ A verage value of climbing speed in ascending zone or descending zone from a start of
data recording (REC ON) up to the present.
E xample: A verage value of climbing speed in zone 1, zone 3 and zone 4 in the diagram
in case of ascending
Average value of climbing speed in zone 2 and zone 5 in the diagram in case of descending
・ T he data when you are resting or walking on fl at ground are excluded.

■ Accumulated ascending/descending altitude
・ T he total value of ascending or descending altitude
Example: T he total value of ascending altitude in zone 1, zone 3 and zone 4 in the dia-
gram in case of ascending
T he total value of descending altitude in zone 2 and zone 5 in the diagram in case of descending
■ Altitude when data recording starts
・ A ltitude ( ① in the diagram) and the time when data recording starts
■ Altitude when data recording ends
・ A ltitude ( ④ in the diagram) and time when data recording ends
■ Maximum/minimum altitude
・ M aximum altitude ( ③ in the diagram) and minimum altitude ( ② in the diagram) from a
start of data recording (REC ON) up to the present, and the arrival time

（10）Mechanism of altitude measurement
・ T his product adopts a method to estimate altitude using the relationship between altitude and at-
mospheric pressure of the International Standard Atmosphere specifi ed by the International Civil
Aviation Organization.
・ U sing a reference altitude set at a place where the correct altitude is known in advance, the
watch measures the difference in altitude based on the change in atmospheric pressure from
there and display the result as the current altitude.
I n the illustration below, the altitude is corrected at a starting point for a trail etc. (200 m). Then,
the diff erence in altitude (400 m) generated by movement is measured and is combined with the
corrected value, and then the altitude (600 m) after movement is displayed.
・ B ecause a change in atmospheric pressure is converted into altitude, display of the altitude also
changes when atmospheric pressure changes even when altitude is measured at the same position.
(Current altitude = Corrected value + Measured value)
Indicator etc.

【CAUTION】Correct measurements cannot be made under the following conditions.
・When atmospheric pressure changes depending on weather condition
・When atmospheric temperature signifi cantly changes
・ When this product receives a strong impact
