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 f our or five seconds f or the
altitude reading to appear after you enter
the Altimeter Mode.
2 . Leav e the watch in the Altimeter Mode if you
want the displa yed altitude value and the
altitude graph contents to be updated at
regular intervals.
•Readings are taken at fiv e-second inter vals f or 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. T o stop the altitude measurement operation, press D to exit the Altimeter
Mode.

Notes
•Normally , display ed altitude values are based on the watch’s preset
conv ersion values. Y ou also can specify a reference altitude, if y ou want.
See “Specifying a Reference Altitude ”.
•Altitude is display ed in units of 5 meters (20 feet).
•The measurement range f or altitude is – 700 to 10,000 meters (– 2,300 to
32,800 feet).
•The measured altitude may be a negativ e value in cases where there is a
reference altitude v alue set or because of cer tain atmospheric conditions.
•The display ed altitude value changes to xxxx meters (or f eet) if a
measured altitude falls outside the measurement r ange. The altitude v alue
will be displa yed again as soon as the measured altitude is within the
allowab le range.
•Y ou can change the measurement unit for displa yed altitude v alues to either
meters (m) or f eet (ft). See “T o select the temperature, barometric pressure,
and altitude units”.
Saving Altitude Data
The watch automatically keeps trac k of the high altitude achiev ed to date.
Y ou also can save altitude readings with the touch of a b utton.
•Y ou can recall and view altitude data using the Data Recall Mode. For
details, see “Recalling Altitude Data ”.
Automatic High Altitude Recor d
Whenev er an altitude measurement in the Altimeter Mode is greater than the
currently stored high altitude value, the w atch will replace the old value with
the new measurement automatically , along with the reading date and time.
This feature is alwa ys enabled and cannot be tur ned off.
•If the current reading is the same as the e xisting high altitude value, the
older value will be retained.
Saving an Altitude Reading
P erform the follo wing procedure whene ver y ou want to sav e 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 sav ed
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 sav e 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 ne w reading.

Specifying a Reference Altitude
After you specify a ref erence altitude, the watch adjusts its air-pressure-to-
altitude conv ersion calculation accordingly . The altitude measurements
produced by this watch are subject to error caused b y changes in air
pressure. Because of this, we recommend that you update the ref erence
altitude whenev er 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 v alue star ts to flash. This is
the setting screen.
2. Press A (+) or C (–) to change the current
reference altitude v alue by 5 meters (or 20 f eet).
•Y ou can set the reference altitude within the
range of – 10,000 to 10,000 meters (– 32,800
to 32,800 f eet).

•Pressing A and C at the same time returns to OFF (no reference
altitude), so the watch perf orms air pressure to altitude conversions
based on preset data only .
3. Press E to exit the setting screen.
Altitude graph
The altitude graph sho ws Altimeter Mode
measurement results.
•The vertical axis of the graph represents
altitude, and each dot stands f or 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 min utes,
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 b lank (skipped).

Recalling Altitude Data
In the Data Recall Mode, y ou 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 perf or med in the Data Recall Mode.
Data Screens
The follo wing 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 do wn E until
CLR flashes on the display and the w atch
beeps twice.
•Releasing E at any time while CLR is
flashing on the displa y will cancel the delete
operation.
2 . K eep 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 b y you
After you specify a ref erence altitude, the watch uses that value to con vert the
current measured barometric pressure value to altitude.
•When mountain climbing, you can set the
reference v alue in accordance with a marker
along the wa y or altitude information from a
map . After that, the altitude readings
produced by the watch will be more accur ate
than they w ould without a reference altitude.
Displaying Y our Current Altitude
Y ou can use the procedure described in this section to display your current
altitude. If you leave the w atch in the Altimeter Mode, it will update the
display ed altitude value regularly , and indicate reading-to-reading changes in
the altitude graph at the top of the displa y .
Important!
•The procedure in this section simply displa ys values indicating your current
altitude, without storing them in watch memory . For inf ormation about
recording altitude readings in watch memory , see “ Sa ving Altitude Data” .
