CHANGING THE MEASUREMENT UNITS
You can change the measured values displayed by the watch between the
following units.
Altitude: meters (m)
feet (ft)
Temperatures: Celsius ( C)
Fahrenheit ( F)
Barometric Pressure: hecto-pascals/millibars (hPa/mb)
*
Some countries call this unit hecto-pascal (hPa), while other countries call
it millibars (mb). It really makes no difference, because 1 hPa = 1 mb. In
this manual, we will refer to hPa/mb or hPa (mb).
Important!
Certain measurement functions are automatically terminated when you
change the measurement units. Be sure that you perform this operation
before starting actual measurements.
Changing the altitude unit of measurement automatically switches the
altitude alarm off.
Changing the barometric pressure unit of measurement automatically restarts
the barometric pressure graph from a new value.
Changing any of the units of measurement immediately starts to display
newly measured data in the unit you specify. It also affects the unit of
measurement for any data already stored in memory.

seconds to "00". If you press D while the seconds count is in the range of
30 to 59, it is reset to "00" and 1 is added to the minutes. If the seconds
count is in the range of 00 to 29, the minutes count is unchanged.
Press B to switch between the 12-hour and 24-hour formats.
5. While any other digits (besides seconds) are selected (flashing), press D
to increase the number. Holding down D changes the current selection at
high speed.
6. After you set the time and date, press A to return to the Timekeeping
Mode (Timekeeping Display).
The day of the week is automatically set in accordance with the date.
The date can be set within the range of January 1, 1995 to December 31,
2039.
If you do not operate any button for a few minutes while a selection is
flashing, the flashing stops and the watch goes back to the Timekeeping
Mode automatically.

BAROMETER FUNCTIONS
This watch uses a pressure sensor to measure air pressure. This sensor can
be calibrated.
Important!
The barometer that is built into this watch measures changes in air pressure,
which you can then apply to your own weather predictions. It is not intended
for use as a precision instrument in official weather prediction or reporting
applications.
Example barometer applications
Before going mountain climbing, you can take readings to find out the
probable upcoming weather.
You can predict the weather for golf or other outdoor activities.
About barometric measurements
The barometer automatically takes measurements every two hours (starting
from midnight), regardless of what mode you are in. Barometric pressure
measurements are also taken every five seconds for three minutes after you
display the Timekeeping Mode's Barometric pressure/Temperature display.
The last measurement result, along with the current temperature is displayed
in the Barometric pressure/Temperature display.
Understanding the barometer display
1. Use C to enter the Timekeeping Mode.
2. Press D to display the Barometric Pressure/Temperature Display.

1 The barometric pressure graph shows the barometric readings for the
past 26 hours. The flashing point on the right of the display is the point for
the last measurement.
*
2 The display shows "– – – – hPa/mb" (or inHg) if a measured value falls
outside the range of 460 hPa/mb to 1100 hPa/mb (13.55 inHg to 32.45
inHg). The normal display will return as soon as the pressure returns
within the allowable range.
Using the barometric pressure graph
Changes in barometric pressure are caused by changes in the weather and
temperature. The following shows how to interpret the data that appears on
the barometric pressure graph.
Note that if there are sudden
changes in weather or tempera-
ture, the graph line of past meas-
urements may run off the top or
bottom of the display. The entire
graph will become visible once
barometric conditions stabilize.
The following conditions cause the barometric pressure measurement to be
skipped, with the corresponding point on the barometric pressure graph
being left blank.

13.55 inHg to 32.45 inHg)

Calibrating the barometric pressure measurement
The sensor of this watch is calibrated at the factory before shipment and
further adjustment is normally not required. If noticeable error is found in the
barometric pressure readings produced by the watch, you can adjust it to
correct the error.
Important!
Incorrectly calibrating the barometric pressure measurement of this watch
can result in incorrect readings. Compare the readings produced by the
watch with those of another reliable accurate barometer.
