• If you want to cancel bearing sensor correction, press D in step 5 instead of C.

This will return to the screen in step 2. From there you can press A to exit the

calibration screen.

• The indicator will go around the display up to four times, if you do not stop it by

pressing C. After the fourth time, the watch will exit the calibration screen

automatically.

To perform magnetic declination correction

1. In the Digital Compass/Thermometer Mode, hold down

A until the indicator at the 12 o’clock position starts to

flash. This is the calibration screen.

2. Press C.

• The magnetic declination angle and magnetic

declination angle direction will flash on the display.

3. Use D (+) and B (–) to change the magnetic

declination angle and magnetic declination angle

direction settings.

• You can select a value within the range of 90° W to 90° E with these settings.

• The following explains magnetic declination angle direction settings.

0 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 turn off (0 OFF) magnetic declination correction (which effectively makes

the magnetic declination angle: 0°) by pressing D and B 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.

4. When the setting is the way you want, press A to exit the setting screen.

Using the Digital Compass While Mountain Climbing or Hiking

This section describes three real-life situations where you could use the watch’s built-

in digital compass.

• To set a map and find 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.

• To find the bearing to an objective

To set a map and find your current location

1. With the watch on your wrist, position it so the face is

horizontal.

2. In the Timekeeping Mode, press D to take a compass

reading.

• The reading will appear on the display after about two

seconds.

3. Rotate the map without moving the watch so the

northerly direction indicated on the map matches north

as indicated by the watch.

• If the watch is configured to indicate magnetic north,

align the map’s magnetic north with the watch

indication. If the watch has been configured with a

declination to correct to true north, align the map’s

true north with the watch indication.

•This will position the map in accordance with your

current location.

4. Determine your location as you check the geographic

contours around you.

To find the bearing to an objective

1. Take a compass reading and then set the map so its

northerly indication is aligned with north as indicated by

the watch, and determine your current location.

• See “To set a map and find your current location” for

information about how to perform the above step.

2. Set the map so the direction you want to travel on the

map is pointed straight in front of you.

3. With the watch on your wrist, position it so the face is

horizontal.

4. In the Timekeeping Mode, press D to take a compass

reading.

• The reading will appear on the display after about two

seconds.

5. Still holding the map in front of you, turn your body until

north as indicated by the watch and the northerly

direction on the map are aligned.

• This will position the map relative to your current location, so the bearing to your

objective is straight ahead of you.

Questions & Answers

Question: What causes incorrect direction readings?

Answer:

• Nearby source of strong magnetism, such as a household appliance, a large steel

bridge, a steel beam, overhead wires, etc., or an attempt to perform direction

measurement on a train, boat, etc. Move away from large metal objects and try

again. Note that digital compass operation cannot be performed inside a train, boat,

etc.

Question: What causes different direction readings to produce different results

at the same location ?

Answer: Magnetism generated by nearby high-tension wires is interfering with

detection of terrestrial magnetism. Move away from the high-tension wires

and try again.

Question: Why am I having problems taking direction readings indoors ?

Answer: A TV, personal computer, speakers, or some other object is interfering with

terrestrial magnetism readings. Move away from the object causing the

interference or take the direction reading outdoors. Indoor direction readings

are particularly difficult inside ferro-concrete structures. Remember that you

will not be able to take direction readings inside of trains, airplanes, etc.

World Time

World Time displays the current time in 48 cities (29 time

zones) around the world.

• If the current time shown for a city is wrong, check your

Home City time settings and make the necessary

changes.

• All of the operations in this section are performed in the

World Time Mode, which you enter by pressing C.

To view the time in another city

In the World Time Mode, use D (east) to scroll through

city codes (time zones).

• For full information on city codes, see the “City Code

Table”.

To toggle a city code time between Standard Time and Daylight Saving Time

1. In the World Time Mode, use D (east) to display the

city code (time zone) whose Standard Time/Daylight

Saving Time setting you want to change.

2. Hold down A to toggle between Daylight Saving Time

(DST indicator displayed) and Standard Time (DST

indicator not displayed).

• The DST indicator appears on the display whenever you

display a city code for which Daylight Saving Time is

turned on.

• Note that the DST/Standard Time setting affects only the

currently displayed city code. Other city codes are not

affected.

Stopwatch

The stopwatch lets you measure elapsed time, split times,

and two finishes.

• The display range of the stopwatch is 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.

Countdown Timer

You can set the countdown timer within a range of one

minute to 24 hours. An alarm sounds when the countdown

reaches zero.

• You also can select auto-repeat, which automatically

restarts the countdown from the original value you set

whenever zero is reached.

• All of the operations in this section are performed in the

Countdown Timer Mode, which you enter by pressing

To configure countdown start time and auto-repeat settings

1. While the countdown start time is on the display in the

Countdown Timer Mode, hold down A until the hour

setting of the countdown start time starts to flash, which

indicates the setting screen.

• If the countdown start time is not displayed, use the

procedure under “To use the countdown timer” to

display it.

2. Press C to move the flashing in the sequence shown

below, and select the setting you want to change.

3. Perform the following operations, depending on which

setting is currently selected on the display.

• While the start time setting is flashing, use D (+) and

B (–) to change it.

Auto-repeat on indicator

• Set

0:00

to specify 24 hours.

• While the auto-repeat on/off setting (0N or 0FF) is flashing on the display, press

D to toggle auto-repeat on (0N) and off (0FF).

4. Press A to exit the setting screen.

• The auto-repeat on indicator (

) is displayed on the Countdown Timer Mode

screen while this function is turned on.

• Frequent use of auto-repeat and the alarm can run down battery power.
