Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off.
•
Figure 8 Calibration, 3-point Calibration
You should perform calibration whenever direction readings produced by the watch do not match those
of another reliable compass, and before setting off on a trek or climb. Leave the watch on your wrist
when performing fi gure 8 calibration. When performing 3-point calibration, remove the watch from your
wrist. Both calibration methods calibrate the direction sensor. You can use either method for calibration.
Important!
•
If the readings produced by the digital compass of this watch are different from those of the other
compass, perform fi gure 8 calibration or 3-point calibration of the digital compass to ensure more
accurate readings. Accurate measurements and/or calibration will not be possible in an area exposed
to strong magnetic force and indoors (especially inside reinforced concrete structure). In this case,
moving outdoors, away from the source of magnetism for measurement and calibration is
recommended.
•
Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle (difference between
magnetic north and true north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are using. Note that you can
input the declination angle in whole degree units only, so you may need to round off the value specifi ed
on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6°
input 8°. For 7.5° you can input 7° or 8°.

Note
•
The watch will return to the Timekeeping Mode about 60 seconds after the direction reading
operation is complete.
•
To restart a reading operation from the beginning, press
C
.
•
Pressing
B
will return to the Timekeeping Mode even if a reading operation is in progress.
Important!
•
If the second hand does not point exactly at 12 o’clock after you perform step 4 above, perform the
operation under “Hand Home Position Adjustment” (page E-41) to adjust it.
•
If the digital display contents start to fl ash after you perform a reading operation, it means that
abnormal magnetism has been detected. Move away from any potential source of strong magnetism
and try taking a reading again. If the problem occurs when you try again, continue to keep away from
the source of strong magnetism, perform fi gure 8 calibration or 3-point calibration, and then try taking a
reading again. For more information, refer to “To perform fi gure 8 calibration” (page E-48), “To perform
3-point calibration” (page E-50) and “Location” (page E-57).
Digital Compass Readings
•
After the fi rst reading is obtained, the watch will continue to take digital compass readings automatically
each second for up to 60 seconds. After that, the reading operation will stop automatically.
•
The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is northwest (
NW
) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
•
You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
•
Any ongoing direction reading operation is paused temporarily while the watch is performing an alert
operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by
pressing
L
). The direction reading operation resumes for its remaining duration after the operation
that caused it to pause is fi nished.
E-45
To take a direction reading
1. Make sure the watch is in the Timekeeping, Digital Compass, or Altimeter Mode (page E-32).
2. Point the 12 o’clock position of the watch in the direction whose reading you want to take.
3. Press
C
to start.
•
COMP
will appear in the display to indicate that a digital compass operation is in progress.
•
Starting a digital compass operation will cause the second hand to move momentarily to the 12
o’clock position. After that, it will indicate magnetic north.

Taking Direction Readings
You can use the Digital Compass Mode to determine the direction of north, and to check your bearing to a
destination.
•
For information about what you can do to improve digital compass reading accuracy, see “Calibrating
the Bearing Sensor” (page E-47) and “Digital Compass Precautions” (page E-56).
•
This watch has an auto level correction function that can be used when it is diffi cult to position the
watch correctly during Digital Compass readings while mountain climbing, etc.

To return the hands to their normal positions
Press any one of the following buttons:
A
,
B
,
C
, or
D
.
Note
•
The hands will also return to their normal positions if you do not perform any operation for about 10
seconds.
•
If the hands have moved to 2 o’clock because you pulled out the crown,* they will return to their normal
positions when you push the crown back in. In this case, the hands will return to normal timekeeping
when you push the crown back in.
* The hands will not move to 2 o’clock if you pull out the crown while confi guring the city code
setting (pages E-36, E-113) or the summer time setting (pages E-36, E-113), or while manually configuring time
(page E-38).
Auto Hand Shift
If the hour hand and/or minute hand is over the digital display when a displayed altitude, barometric
pressure, or temperature reading is updated, the hand(s) will shift automatically (to 10 o’clock or 2 o’clock)
and provide a better view of the information on the display.
The hands will return to their normal position after about three seconds.

Moving the Hands for Easy Viewing of the Digital Display
You can use the procedure below to move the analog hands in order to better view a digital display.
Note
•
The analog hands will not move while battery power is low.
To shift the hands and view digital info
While holding down
L
, press
B
.
•
This will cause all hands to move to 2 o’clock.

Hand Home Position Adjustment
If the watch is exposed to strong magnetism or impact, its hands can go out of alignment with the time on
the digital display. This can result in incorrect time indication even though a time calibration signal is being
received. The watch periodically corrects hand positions automatically. You can also use the procedure
below to trigger hand position adjustment manually when required.
To trigger hand home position adjustment manually
1. In the Timekeeping Mode, pull out the crown.
2. Hold down
A
for at least fi ve seconds until
HAND SET
fl ashes and
then
HAND ADJ
appears on the digital display.
•
This indicates the hand home position adjustment mode.
Important!
•
Before performing step 3, below, make sure that all hands have
returned to the 12 o’clock position. Pushing the crown back in
while any hand is not at the 12 o’clock position will not trigger
home position adjustment.
3. Push the crown back in.
•
This will cause all of the hands (hour, minute, second) to return to
their normal positions.
•
The small hand will also return to tide level indication.
Note
After performing the above steps, enter the Timekeeping Mode and check to make sure that the analog
hands and the display indicate the same time. If they do not, trigger home position adjustment again.

While 12-hour timekeeping is in use,
P
(p.m.) is displayed from noon to midnight (11:59 p.m.)
A
(a.m.) is displayed from midnight to noon (11:59 a.m.) These indicators are not displayed while 24-

•
The watch’s built-in full automatic calendar makes allowances for different month lengths and leap
years. Once you set the date, there should be no reason to change it except after you have the
watch’s rechargeable battery replaced or after power drops to Level 5 (page E-15).
•
The day of the week changes automatically when the date changes.
To switch between 12-hour and 24-hour timekeeping
1. In the Timekeeping Mode, pull out the crown.
2. Press
B
seven times.
•
This causes the current timekeeping setting (
12H
or
24H
) to fl ash on the digital display.
3. Rotate the crown to select either 12-hour (
12H
) or 24-hour (
24H
) timekeeping.
4. After the setting is the way you want, push the crown back in.
