To take an altitude reading

Pressing 

D

 in the Timekeeping Mode or in the

Barometer/Thermometer Mode enters the
Altimeter Mode and automatically starts altitude
measurement.

It can take up to four or five seconds for the
altitude reading to appear after you enter the
Altimeter Mode.

The Altimeter Mode screen also displays the
current temperature. See “Barometer/
Thermometer” for more information.

During the first two or three

 

minutes after

entering the Altimeter Mode, the 

 indicator

flashes on the display and measurements are
taken every five seconds. After that, the 
indicator stops flashing and remains on the
display as measurements are taken every two
minutes.

Altitude

Temperature

Pressing 

D

 causes the measurement operation to restart from the

beginning of the cycle described above.

Altitude is displayed in units of 5 meters (20 feet).

The measurement range for altitude is –700 to 4,000 meters (–2,300 to
13,120 feet). The display range for altitude (include values based on the
reference altitude) is –4,000 to 4,000 meters (–13,120 to 13,120 feet).

An altitude reading may result in a negative value in cases when you have
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 unit of measurement for the displayed altitude values
between meters (m) and feet (ft). See “To change the altitude unit”.

Setting a Reference Altitude

After you set 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 

A

 until

OFF

 appears (flashing) or until the display

goes blank. This is the setting screen.

Wait for four or five seconds before
performing step 2, below. If you don’t wait,
there is the chance of setting value error.

If the display went blank in step 1, the
current reference value will appear
(flashing) on the display after the four or five
seconds pass.

If 

OFF

 or the current reference altitude value does not appear at this

time, press 

A

 to return to the Altimeter Mode screen, and perform step

1 again.

2. Press 

D

 (+) or 

B

 (–) to change the current reference altitude value by 5

meters (or 20 feet).

You can set the reference altitude within the range of –4,000 to 4,000
meters (–13,120 to 13,120 feet).

Pressing 

D

 and 

B

 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 

A

 to exit the setting screen.

Depth Gauge

The pressure sensor of the watch can also be used to perform underwater
depth measurement while skin diving or snorkeling. Depth readings are taken
every three seconds, and displayed as a value up to 30 meters (98 feet).  You
can store the data of your last dive in log memory, including total time
submerged, maximum depth, and water temperature at the maximum depth
attained during your dive. You can view the log data of your last dive before
beginning a new dive.

Important!

Never use this watch to measure depth while scuba diving.

This watch is designed to start depth measurement and record data in
memory after a depth of 1 meter (4 feet) is reached. Because of this, the
explanations in this User’s Guide uses the term “

submerged

” to refer to

any depth deeper than 1 meter, and the “

on the surface

” to refer to any

depth shallower than 1 meter.

Leaving the watch in the Depth Gauge Mode while not in the water
consumes battery power. Exit the Depth Gauge Mode whenever you are
not using it.

The measurement unit selected in the Altimeter Mode is also used in the
Depth Gauge Mode.

What is “a dive”?

A dive starts when you pass a depth of one meter (about four feet) while the
watch is in the Depth Gauge Mode. The dive ends when you are on the
surface and exit the Depth Gauge Mode. A dive does not end if you surface
but do not exit the Depth Gauge Mode.

Enter the Depth Gauge Mode.

Exit the Depth Gauge Mode.

End of dive

Remember that the term “dive” as used in this manual refers to skin diving
or snorkeling only.

The watch will start depth measurement automatically when the sensor
detects that your depth exceeds one meter (about four feet).

Depth measurement stops automatically whenever your depth becomes
less than one meter (four feet).

Depth measurement restarts whenever you re-submerge past one meter
(four feet).  All data that is measured between the start of the dive and the
end of the dive is treated as part of the same dive, no matter how many
times you surface during the dive.

To perform depth measurement

1. Before beginning a dive, enter the

Timekeeping Mode and then press 

C

 to enter

the Depth Gauge Mode.

It can take up to four or five seconds until

 (or 

0

) appears on the display.

2. Enter the water and submerge past one meter

(four feet) to start the dive.

3. When you want to end the dive, return to the surface and then press 

C

 to

exit the Depth Gauge Mode.

Exiting the Depth Gauge Mode causes the data accumulated during the
dive (time submerged, maximum depth attained, water temperature at
maximum depth) to be stored in log memory.

The watch will not exit the Depth Gauge Mode if any value other than 
(or 

0

) is displayed for the depth when you press 

C

. If 

 (or 

0

) does not

appear on the display even though you are on the surface (depth of less
than 1 meter/4 feet), perform the procedure under “To manually reset the
reference depth to 0 meters (feet)”.

See “Log Data” for information about viewing dive data.

To view water temperature and maximum depth

In the Depth Gauge Mode, you can press 

D

 toggles the display between the

Elapsed Measurement Time/Current Depth and the Water Temperature/
Maximum Depth screens.

If you do not perform any button operation for about five or six seconds
while the Water Temperature/Maximum Depth screen is on the display, the
watch will automatically return to the Elapsed Measurement Time/Current
Depth screen.

Never operate the buttons of the watch while underwater.

Important!

Note the following important precautions whenever using the Depth Gauge
Mode.

 to

toggle between

Before Skin Diving/Snorkeling

Before beginning a dive, check to make sure that none of the
following marks are shown on the display.

 

BATTERY (indicating a weak battery)

 

RECOVER (indicating a weak battery)

 

Err

 

(indicating sensor malfunction)

Make sure that 

 

(or 

0

) is displayed at your current depth.

Make sure that the watch is set to the correct time of day.

Check the glass, case and band for cracks or chips.

Make sure that the band is fastened securely around your wrist.
