Other Altimeter Mode Features
This section explains other features and settings that are available in the
Altimeter Mode. Note that all of the information in this section applies to all
types of Altimeter Mode measurements, unless specifically indicated
otherwise.
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 A.
• This will cause SET to appear on the
display.
2. Release A and wait for four or five more
seconds until either
OFF or the current
reference altitude value (if set) starts to flash.
This is the setting screen.
3. 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 –10,000 to 10,000
meters (–32,800 to 32,800 feet).
• Pressing B and D at the same time returns to
OFF (no reference
altitude), so the watch performs air pressure to altitude conversions
based on preset data only.
4. Press A 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).
Altitude Differential Pointer
While a measurement operation is being performed in the Altimeter Mode, the
altitude differential pointer indicates the difference between the current
altitude and the last measured altitude.

Altitude differential pointer
• Altitude differential is indicated in the range of ±25 meters, in 5-meter units.
• Altitude is calculated and displayed using meters as the standard. Altitude
also can be read in feet units as shown in the illustration.
Altitude Alarm
The altitude alarm sounds for about five seconds when the current altitude
matches a preset value during an altitude measurement operation. You can
press any button to stop the alarm after it starts to sound.
The altitude alarm sounds only while the Altimeter Mode’s Altitude Graph
screen or Altitude Alarm Differential screen is on the display. It does not
sound while the watch is in another mode or while another Altimeter Mode
screen is on the display.
Example
If you set the altitude alarm at 130 meters, it sounds when you pass the 130-
meter mark on your way up and on your way back down.
To set the altitude alarm
1. In the Altimeter Mode, hold down A.
• This will cause SET to appear on the
display.
2. Release A and wait for four or five more
seconds until either
OFF or the current
reference altitude value (if set) starts to flash.
This is the setting screen.
3. Press C once to display the altitude alarm
setting.
4. Press D (+) or B (–) to change the current altitude alarm value by 5
meters (or 20 feet).
• You can set the altitude alarm value within the range of –10,000 to
10,000 meters (–32,800 to 32,800 feet).
•
Pressing B and D at the same time resets the altitude alarm value to O.
5. Press A to exit the setting screen.

Altitude alarm value
To turn the altitude alarm on and off
1. In the Altimeter Mode, hold down A.
• This will cause SET to appear on the
display.
2. Release A and wait for four or five more
seconds until either
OFF or the current
reference altitude value (if set) starts to flash.
This is the setting screen.
3. Press C once to display the altitude alarm
setting.
4. Press L to toggle the altitude alarm on (
ON) and off (OFF).
5. Press A to exit the setting screen.
• An altitude alarm on indicator appears on the Altimeter Mode’s Altitude
Graph screen or Altitude Alarm Differential screen while the altitude alarm
is turned on. This indicator does not appear on any other screen or in any
other mode.

Stopwatch
The stopwatch lets you measure elapsed time,
split times, and two finishes.
• The display range of the stopwatch is 23 hours,
59 minutes, 59.99 seconds.
• The stopwatch continues to run, restarting from
zero after it reaches its limit, until you stop it.
• The stopwatch measurement operation
continues even if you exit the Stopwatch Mode.
• Exiting the Stopwatch Mode while a split time is
frozen on the display clears the split time and
returns to elapsed time measurement.
• All of the operations in this section are
performed in the Stopwatch Mode, which you
enter by pressing C.
