Important!
• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure
readings produced by its pressure sensor. This means that readings taken at different times at the
same location may produce different altitude values due to changes in barometric pressure. 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, be sure to perform regular calibration in
accordance with the local altitude (elevation) indications. For more information, see “To specify a
reference altitude value” (page E-63).

Important!
• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or
totally white, depending on the watch model). The appearance of the LCD should become normal
again when the watch returns to a lower temperature.
• Turn on the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright
light when storing it for long periods. This helps to ensure that power does not run down.
• Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Expose the watch to bright light
whenever possible.
Power Levels
Hold down B for at least two seconds to enter the Timekeeping Mode.

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, leave it in a location where it
is exposed to light.
• Best charging performance is
achieved by exposing the watch to
the strongest light available.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become particularly hot
when exposed to the conditions below for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight

• Leaving the watch exposed to direct sunlight or some other very strong light source can cause the
battery power indicator to show a reading temporarily that is higher than the actual battery level. The
correct battery level should be indicated after a few minutes.
• All data stored in memory is deleted, and the current time and all other settings return to their initial
factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
A dark environment while battery power is at Level 4 will cause the level to drop to Level 5. Expose the
watch to bright light whenever possible.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See “Confi guring Current Time and Date Settings Manually” (page E-38) for more
information.
This section explains how the watch updates its time settings automatically when the city code selected
as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration
signal reception.
If your Home City Code setting is this:

• Even when the watch is within range of a transmitter, signal reception may be impossible due to the
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference,
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the
infl
uence of the conditions listed above becomes even greater.

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
Wait until all of the hands
move to 12 o’clock.
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.
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.

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.

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
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

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
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
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°.
