Sudden Barometric Pressure
Change Indications
Whenever the watch detects a significant
change in air pressure readings (due to
sudden ascent or descent, or to the passage
of a low pressure or high pressure area), it will
beep to let you know. An arrow will also flash
on the display at this time if the watch is in the
Barometer Mode, or if it is in the Timekeeping
Mode with the barometric pressure graph
displayed. The arrow that appears shows the
direction of the pressure change. These alerts
are called “Barometric Pressure Change
Indications”.
This
indicator:
Means this:
Sudden drop in pressure
Sudden rise in pressure
Sustained rise in pressure,
shifting to a fall
Sustained fall in pressure, shifting
to a rise
Important!
●
To ensure correct barometric pressure
change indicator operation, enable it in
a location where the altitude is
constant (such as a lodge, camp area,
or on the ocean).
●
A change in altitude causes a change
in air pressure. Because of this, correct
readings are impossible. Do not take
readings while ascending or
descending a mountain, etc.
1. Enter the Barometer Mode.

2. Hold down (D) for at least two seconds.
If this turns on barometric pressure
change indication, [INFO ON] will stop
flashing and then the [BARO] indicator will
appear on the display.
3. To disable barometric pressure change
indication, hold down (D) again for at least
two seconds.
Note
●
If Barometric Pressure Change
Indications are on, barometric
pressure readings are taken every two
minutes even while the watch is not in
the Barometer Mode.
●
The Barometric Pressure Change
Indication becomes disabled
automatically 24 hours after it is
enabled.
●
You will not be able to turn on
barometric pressure change indication
if the watch’s battery level is low.
●
Low battery power will also cause
barometric pressure change indication
to turn off automatically.
Calibrating Barometric
Pressure Readings (Offset)
The watch’s pressure sensor is adjusted at the
factory and normally does not require
calibration. However, you can calibrate the
displayed value if you notice major errors in
readings.
Important!
●
The watch will not be able to produce
correct barometric pressure readings if
you make a mistake during the
calibration procedure. Check to make
sure that the value you use for
calibration produces correct pressure
readings.
1. Enter the Barometer Mode.

2. Loosen the crown and then pull it out.
This displays the current barometric
pressure and enters the Barometric
Pressure Offset Mode.
Crown
3. Rotate the crown to change the value.
Setting range: 260 to 1,100 hPa (or 7.65
inHg to 32.45 inHg)
Setting unit: 1 hPa (or 0.05 inHg)
●
To return the barometric pressure
setting to its initial factory default, press
(A) and (C) at the same time.
4. Push the crown back in and then lock it.
Note
●
If you do not perform any operation for
about two minutes after pulling out the
crown, crown operations will
automatically become disabled. If that
happens, push the crown back in and
then pull it out again.
