Setting a map and fi nding your current location
Having an idea of your current location is important when mountain climbing or hiking. To do this, you
need to "set the map", which means to align the map so the directions indicated on it are aligned with the
actual directions of your location. Basically what you are doing is aligning north on the map with north as
indicated by the watch.
• Note that map reading skills and experience are required to determine your current location and
destination on a map.
Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as magnetic north or true
True north True north
north, which are different from each other. Also, it is important to keep in mind
that magnetic north moves over time.
• Magnetic north is the north that is indicated by the needle of a compass.
• True north, which is the location of the North Pole of the Earth's axis, is the
north that is normally indicated on maps.
Magnetic north Magnetic north
• The difference between magnetic north and true north is called the
"declination". The closer you get to the North Pole, the greater the
Earth Earth
declination angle.

Specifying Altitude, Barometric Pressure, and Temperature Units
Use the procedure below to specify the altitude, barometric pressure, and temperature units to be used in
the Altimeter Mode, Barometer Mode and the Thermometer Mode.
Important!
• When TYO (Tokyo) is selected as the Home City, the altitude unit is set
automatically to meters (m), the barometric pressure unit to
hectopascals (hPa), and the temperature unit to Celsius (°C). These
settings cannot be changed.
To specify altitude, barometric pressure, and temperature units
1. Make sure the watch is in the mode for the type of unit you want to
specify (Altimeter, Barometer, or Thermometer Mode).
• For information about changing modes, see "Selecting a Mode"
(page E-30).
2. Pull out the crown.
• The timekeeping (hour, minute, second) hands will move to
2 o'clock.
3. Press B as many times as necessary until UNIT appear on the digital
display.
For altitude, press B three times. For barometric pressure and
•
temperature, press B once.
4. Rotate the crown to change the unit setting.
5. After the settings are the way you want, push the crown back in.

Note
• If you do not perform any button operation while in the Altimeter Mode, the watch will return to the
Timekeeping Mode automatically after 12 hours (altitude auto reading interval: 2'00) or after one
hour (altitude auto reading interval: 0'05).
To specify the altitude auto reading interval
1. In the Altimeter Mode, pull out the crown.
• This will cause the current altitude reading value to appear.
• The timekeeping (hour, minute, second) hands will move to 2
o'clock.
2. Press B.
• This will cause INT to appear on the digital display, along with the
fl ashing current auto reading interval setting.
3. Rotate the crown to select either fi ve second (0'05) or two minutes
(2'00) as the interval setting.
4. After the setting is the way you want, push the crown back in to exit the
setting screen.
Taking Altitude Readings
Use the procedure below to take basic altitude readings.
• See "Using Reference Altitude Values" (page E-56) for information about how to make altimeter
readings more accurate.
• See "How does the altimeter work?" (page E-67) for information about how the watch measures altitude.

To perform magnetic declination correction

1. In the Digital Compass Mode, pull out the crown.
• This will cause 1 to appear on the digital display, with up arrow ( )
fl ashing.
• The timekeeping (hour, minute, second) hands will move to
2 o'clock.
2. Press B.
• This will cause DEC and the current magnetic declination setting
to appear on the digital display.
3. Rotate the crown to change the magnetic declination direction and
angle settings as desired.
Magnetic declination Magnetic declination
• The following explains magnetic declination angle direction
angle value angle value
settings.
Magnetic declination angle Magnetic declination angle
direction value (E, W, or OFF) direction value (E, W, or OFF)
OFF: No magnetic declination correction performed. The magnetic
declination angle with this setting is 0°.
E: When magnetic north is to the east (east declination)
W: When magnetic north is to the west (west declination)
• You can select a value within the range of W 90° to E 90° with
these settings.
• You can also use HS1 high-speed movement (page E-5) to change
this setting.
• You can turn off (OFF) magnetic declination correction by pressing
A and C at the same time.
• The illustration, for example, shows the value you should input
and the direction setting you should select when the map shows a
magnetic declination of 1° west.
Location
• Taking a direction reading when you are near a source of strong magnetism can cause large errors in
readings. Because of this, you should avoid taking direction readings while in the vicinity of the
following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal
(metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal
computers, washing machines, freezers, etc.).
• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is
because the metal framework of such structures picks up magnetism from appliances, etc.
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should store the watch away from magnets or any other sources of strong magnetism,
including: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors,
lockers, etc.), and household appliances (TVs, personal computers, washing machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the procedure under "To
perform bidirectional calibration" (page E-48).
Using the Altimeter Mode
The watch takes altitude readings and displays results based on air pressure measurements taken by a
built-in pressure sensor. It also saves various types of altitude records and data.
• The displayed altitude reading is a relative altitude that is calculated based on measurement of
changes in barometric pressure by the watch's pressure sensor. This means that barometric pressure
changes can cause readings taken at different times at the same location to be different. Also note that
the value displayed by the watch may be different from the actual elevation and/or sea level elevation
indicated for the area where you are located. When using the watch's altimeter while mountain
climbing, it is recommended that you perform regular calibration in accordance with the local altitude
(elevation) indications.
Important!
• See "To specify a reference altitude value" (page E-57) and "Altimeter Precautions" (page E-68) for
information about how to minimize differences between readings produced by the watch and values
provided by local altitude (elevation) indications.
Getting Ready
Before actually taking an altitude reading you need to select an altitude reading interval.
Selecting the Altitude Auto Reading Interval
You can select either of the following two altitude auto reading interval.
0'05: Readings at one-second intervals for the fi rst three minutes, and then every fi ve seconds for
approximately the next hour
2'00: Readings at one-second intervals for the fi rst three minutes, and then every two minutes for
approximately the next 12 hours
To take altitude readings
1. Make sure the watch is in the Timekeeping, Digital Compass, or
Altitude Tendency Graph Altitude Tendency Graph
Altimeter Mode.
2. Press A to start auto altimeter readings.
• The current altitude value is displayed in units of 1 meter (5 feet).
• For information about the measurement interval, see page E-53.
Note
When you press A above, the second hand may indicate seconds (of
•
the current time) or the altitude differential (page E-58). The initial
second hand function will be the same as what was selected the last
Altitude Altitude
time you took an altitude reading. To toggle between the two second
hand functions (indicating seconds or indicating the altitude
differential) press D.
To restart a reading operation from the beginning, press A.
•
After you are fi nished, press B to return to the Timekeeping Mode and
•
stop auto altimeter readings.
• The watch will return to the Timekeeping Mode automatically if you do
not perform any operation (page E-32).
• The measurement range for altitude is –700 to 10,000 meters (–2,300
to 32,800 feet).
• The displayed altitude value changes to - - - - if an altitude reading falls outside the measurement
range. An altitude value will reappear as soon as the altitude reading is within the allowable range.
• You can change the unit for displayed altitude values to either meters (m) or feet (ft). See "To specify
altitude, barometric pressure, and temperature units" (page E-52).
