Operation Manual

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.
●
Barometric Pressure Change
Indications turn off automatically 24
hours after it is turned on.
●
Time signal reception is disabled
while Barometric Pressure Change
Indications are turned on. Power
saving is also disabled.
l
Power Saving Function
●
You will not be able to turn on
Barometric Pressure Change
Indications are while charge level of
the watch’s battery is low.
●
Low battery power will also cause
barometric pressure trend
information to turn off.
Calibrating Barometric
Pressure Readings
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 temperature 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.
Pull out the crown.
Crown
2.
Rotate the crown to change the value.
Calibration Unit: 1 hPa (0.05 inHg)
●
To return the barometric pressure
setting
to its initial factory default, press
(A) and (C) at the same time.
3.
Push the crown back in to complete the
setting operation.
Specifying the Barometric
Pressure Measurement Unit
You can specify either hectopascals (hPa) or
inches
of mercury (inHg) as the display unit for
barometric pressure values.
Important!
●
When Tokyo (TYO) is set as the
Home City, the barometric pressure
unit is fixed as hectopascals (hPa)
and cannot be changed.
1.
Pull out the crown.
Crown
2.
Press (B).
3.
Rotate the crown to select hectopascals
(hPa) or inches of mercury (inHg) as the
measurement unit.
4.
Push the crown back in to complete the
setting operation.
Barometric Pressure
Reading Precautions
●
The barometric pressure graph produced
by
this watch can be used to obtain an idea
of upcoming weather conditions. However,
this watch should not be used in place of
precision instruments required for official
weather prediction and reporting.
●
Pressure sensor readings can be affected
by sudden changes in temperature.
Because
of this, there may be some error in
the readings produced by the watch.
Temperature
Measurement
The watch can be used to take current air
temperature readings.
Important!
●
Check the information below to find
out how to ensure correct readings.

Temperature Reading Precautions
Getting ready
Enter the Temperature Mode.
l
Navigating Between Modes
Thermometer Mode
●
Entering the Temperature Mode starts
temperature readings.
Checking the Current
Temperature
Entering the Temperature Mode displays
temperature reading results. After you enter
the Temperature Mode, the watch takes
readings about every five seconds for three
minutes. After that, a measurement is taken
about every two minutes.
●
To retrigger measurement, press (A).
Note
●
The watch will automatically return
to the Timekeeping Mode if you do
not perform any operation in the
Temperature Mode for about one
hour.
●
The measuring range is -10.0 °C to
60.0 °C (14.0 °F to 140.0 °F) (0.1 °C
(0.2 °F) units). [- - .-] will appear for
the measured value if it is outside the
allowable range.
●
To
return to the Timekeeping Mode,
hold down the (B) button for about
two seconds.
