Auto Altitude Data Recording
●
The altitude data described below is recorded
automatically while the watch is in the Altitude
Mode. One record each is maintained in
memory for each of these items.
E
Start point
C
B
A
F
End point
High Altitude (MAX): E
Low Altitude (MIN): F
Cumulative Ascent (ASC): A + C
Cumulative Descent (DSC): B + D
* Cumulative ascent and cumulative descent
values are updated whenever there is a
difference of at least ±15 m (±49 feet) from
one reading to the next.
Note
Auto recording ends when you exit the
●
Altimeter Mode. Re-entering the
Altimeter Mode restarts recording of
cumulative values from where it was
stopped when you last exited the
Altimeter Mode.
Auto measurement continues if you go
●
from the Altimeter Mode to another
mode while Mission Log is enabled.
Every time an auto measurement
●
operation is performed while Mission
Log is enabled, the watch checks the
currently saved values of the following
data items and updates them as
required: MAX, MIN, ASC, DSC.

Specifying the Altitude
Measurement Unit
You can select either meters (m) or feet (ft) as
the Altimeter Mode display unit.
Important!
When Tokyo (TOKYO) is set as the
●
D
Home City, the altitude unit is fixed as
meters (m) and cannot be changed.
1.
Enter the Timekeeping Mode.

2.
Hold down (D) for at least two seconds.
Release the button when the name of the
currently selected Home City appears on
*
the display.

Press (E) seven times.
This causes [UNIT] to appear, with [m] or

Altitude Reading
Precautions
Effects of Temperature
When taking altitude readings, take the steps
below to keep the watch at as stable a
temperature as possible. Changes in
temperature can affect altitude readings.
Take readings with the watch on your wrist.
●
Take readings in an area where
●
temperature is stable.
Altitude Readings
Do not use this watch while skydiving, hang
●
gliding, paragliding, gyrocopter flying, glider
flying, or engaged in other activities where
altitude changes suddenly.
Altitude readings produced by this watch
●
are not intended for special-purpose or
industrial level use.
In an aircraft, the watch measures the in-
●
cabin pressurized air pressure, so readings
will not match altitudes announced by the
crew.
Altitude Readings (Relative Altitude)
Home City
This watch uses International Standard
Atmosphere (ISA) relative altitude data
defined by the International Civil Aviation
Organization (ICAO). Barometric pressure
generally becomes lower as altitude
increases.
Correct measurement may not be possible
under the conditions below.
During unstable atmospheric conditions
●
During sudden temperature changes
●
After the watch has been subjected to
●
strong impact
Barometric Pressure
You can use the Barometer Mode to take a
reading of the barometric pressure at your
current location, and to track reading changes
and trends.
Feet
Important!

●
how to ensure correct readings.
