To display your current altitude
1. Press
A
in the Timekeeping Mode or in any
of the other sensor modes to enter the
Altimeter Mode.
•
The watch will start altitude measurement
automatically, and display the result.
•
It can take up to four or five seconds for the
altitude reading to appear after you enter
the Altimeter Mode.
2. Leave the watch in the Altimeter Mode if you
want the displayed altitude value and the
altitude graph contents to be updated at
regular intervals.
•
Readings are taken at five-second intervals for the first three minutes
after you enter the Altimeter Mode. After that, readings are taken at two-
minute intervals.
•
If you want to restart the altitude measurement operation at any point,
press
A
.
3. To stop the altitude measurement operation, press
D
to exit the Altimeter
Mode.

Notes
•
Normally, displayed altitude values are based on the watch’s preset
conversion values. You also can specify a reference altitude, if you want.
See “Specifying a Reference Altitude”.
•
Altitude is displayed in units of 5 meters (20 feet).
•
The measurement range for altitude is –700 to 10,000 meters (–2,300 to
32,800 feet).
•
The measured altitude may be a negative value in cases where there is a
reference altitude value set or because of certain atmospheric conditions.
•
The displayed altitude value changes to
xxxx
meters (or feet) if a
measured altitude falls outside the measurement range. The altitude value
will be displayed again as soon as the measured altitude is within the
allowable range.
•
You can change the measurement unit for displayed altitude values to either
meters (m) or feet (ft). See “To select the temperature, barometric pressure,
and altitude units”.
Saving Altitude Data
The watch automatically keeps track of the high altitude achieved to date.
You also can save altitude readings with the touch of a button.
•
You can recall and view altitude data using the Data Recall Mode. For
details, see “Recalling Altitude Data”.
Automatic High Altitude Record
Whenever an altitude measurement in the Altimeter Mode is greater than the
currently stored high altitude value, the watch will replace the old value with
the new measurement automatically, along with the reading date and time.
This feature is always enabled and cannot be turned off.
•
If the current reading is the same as the existing high altitude value, the
older value will be retained.
Saving an Altitude Reading
Perform the following procedure whenever you want to save an altitude reading.
To save an altitude reading
1. Press
A
to enter the Altimeter Mode.
2. Hold down
A
until
REC
flashes on the
display.
•
At this time the watch will beep and the
current altitude reading value will be saved
along with the reading date (month - day)
and time.
3.
REC
will stop flashing and the watch will
return to the Altimeter Mode automatically
after data save is complete.
•
Memory can store up to 24 altitude records. Storing a new reading while
there are already 24 in memory will delete the oldest record currently in
memory to make room for the new reading.

Specifying a Reference Altitude
After you specify a reference altitude, the watch adjusts its air-pressure-to-
altitude conversion calculation accordingly. The altitude measurements
produced by this watch are subject to error caused by changes in air
pressure. Because of this, we recommend that you update the reference
altitude whenever one is available during your climb.
To set a reference altitude
1. In the Altimeter Mode, hold down
E
for about
two seconds until either
OFF
or the current
reference altitude value starts to flash. This is
the setting screen.
2. Press
A
(+) or
C
(–) to change the current
reference altitude value by 5 meters (or 20 feet).
•
You can set the reference altitude within the
range of –10,000 to 10,000 meters (–32,800
to 32,800 feet).

•
Pressing
A
and
C
at the same time returns to
OFF
(no reference
altitude), so the watch performs air pressure to altitude conversions
based on preset data only.
3. Press
E
to exit the setting screen.
Altitude graph
The altitude graph shows Altimeter Mode
measurement results.
•
The vertical axis of the graph represents
altitude, and each dot stands for 10 meters (40
feet).
•
The horizontal axis represents time, and the flashing dot in the rightmost
column indicates the latest measurement result. For the first three minutes,
each dot represents five seconds. After that, each dot represents two
minutes.
•
An out of range measurement result or a measurement error will cause the
column of dots for that measurement to be blank (skipped).

Recalling Altitude Data
In the Data Recall Mode, you can recall and view altitude reading records you
stored in the Altimeter Mode, as well as the high altitude record.
•
All of the operations in this section are performed in the Data Recall Mode.
Data Screens
The following explains the contents of each of the screens that appear in the
Data Recall Mode.
To delete all altitude data currently in memory
1. In the Data Recall Mode, hold down
E
until
CLR
flashes on the display and the watch
beeps twice.
•
Releasing
E
at any time while
CLR
is
flashing on the display will cancel the delete
operation.
2. Keep
E
depressed for two seconds.
•
The watch will beep to indicate that all of the
altitude data stored in watch memory (including
readings you stored and the high altitude
value) is deleted.

When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch uses that value to convert the
current measured barometric pressure value to altitude.
•
When mountain climbing, you can set the
reference value in accordance with a marker
along the way or altitude information from a
map. After that, the altitude readings
produced by the watch will be more accurate
than they would without a reference altitude.
Displaying Your Current Altitude
You can use the procedure described in this section to display your current
altitude. If you leave the watch in the Altimeter Mode, it will update the
displayed altitude value regularly, and indicate reading-to-reading changes in
the altitude graph at the top of the display.
Important!
•
The procedure in this section simply displays values indicating your current
altitude, without storing them in watch memory. For information about
recording altitude readings in watch memory, see “Saving Altitude Data”.
