Charging the Watch
The face of the watch is a solar cell 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.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
•The watch may enter a sleep state
(page E-14) if its face is blocked
by your sleeve even only partially.
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 following conditions for long periods.
•On the dashboard of a car parked in direct sunlight
•Too close to an incandescent lamp
•Under direct sunlight
E-10
Important!
•Allowing the watch to become very hot can cause its liquid crystal display to black out. 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-14) 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.
E-11
Power Levels
You can check the current battery power level by viewing the battery power indicator that appears on the
digital display when you enter the Timekeeping Mode.
•To enter the Timekeeping Mode from any other mode, hold down Dfor about two seconds.

•The flashing
Lindicator at Level 3 tells you that battery power is very low, and that exposure to bright
light for charging is required as soon as possible.
•At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery
reaches Level 2 (
M) after falling to Level 5, reconfigure the current time, date, and other settings.
•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (
M).
•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.
Charging Required Indication (by second hand)
When battery power reaches Level 3, the second hand of the watch will
jump at 2-second intervals in the Timekeeping Mode to let you know that
charging is required.
Power Recovery Mode
•Repeated sensor measurement, illumination, or use of tones over a short period of time may cause the
watch to enter a power recovery mode, which is indicated by a recovery indicator (
R) to flash on the
digital display. The watch will remain in the power recovery mode until battery power recovers.
E-13
•Illumination, tones, and sensor operations are disabled and the hands of the watch stop until battery
power recovers.
•Battery power takes about 15 minutes to recover. The recovery indicator (
R) will stop flashing and
normal watch operation will be restored when battery recovery is complete.
•Frequent flashing of the recovery indicator (
R) indicates that battery power is low. Expose the watch to
light to charge its battery.

the Specifications (page E-106).
E-14
Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area
where it is dark. The table below shows how watch functions are affected by Power Saving.
•There actually are two sleep state levels: “display sleep” and “function sleep”.
•With this watch, the Power Saving function cannot be disabled.
Elapsed Time in Dark Hands and Display Operation
60 to 70 minutes (display sleep) Blank display, second hand
stopped at 12 o’clock.
Except for display and second hand, all
functions enabled.
6 or 7 days (function sleep) Blank display, all hands
stopped at 12 o’clock.
Except for timekeeping, all functions
disabled.
•The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
•You will not be able to enter the Compass, Barometer/Thermometer, Altimeter, Stopwatch, or
Countdown Timer Mode while the watch is in a sleep state.
To recover from the sleep state
Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page
E-91).
E-15
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 “Configuring Current Time and Date Settings Manually” (page E-31) for more
information.
This section explains how the watch updates its time settings 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: The watch can receive the signal from the transmitter
located here:
LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainflingen (Germany)
HONG KONG (HKG) Shangqiu City (China)
TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)
HONOLULU (HNL), ANCHORAGE (ANC),
LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI),
NEW YORK (NYC)
Fort Collins, Colorado (United States)
Important!
•The areas covered by HONOLULU (
HNL) and ANCHORAGE ( ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
•When HONG KONG (
HKG) is selected as the Home City, only the time and date are adjusted
according to the time calibration signal. You need to switch manually between standard time and
daylight saving time (DST) if required. See “To configure Home City settings” (page E-28) for
information about how to do 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
influence of the conditions listed above becomes even greater.
•Signal reception may not be possible at the distances noted below during certain times of the year or
day. Radio interference may also cause problems with reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)

while the hands are moving.
Note
• For information about selecting a Home City and configuring the DST setting, see “Configuring
Home City Settings” (page E-28).
• Changing the time on the digital display will cause the time indicated by the hands to change
accordingly. If the displayed time and the time indicated by the hands do not match, it could mean
that the hand home positions are off. Adjust the hand home positions as required (page E-86).
• While 12-hour format is selected, a P(PM) indicator will appear for times from noon to 11:59 p.m. No
indicator appears for times from midnight to 11:59 a.m. With 24-hour format, time is displayed from
0:00 to 23:59, without any P(PM) indicator.
• 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-11).

Taking Direction Readings
The Compass Mode uses the watch’s direction sensor to detect magnetic north. The second hand will
indicate magnetic north and the digital display shows one of 16 directions and an angle value.
To take a direction reading
1. Check to make sure the watch is in the Timekeeping Mode or one of
the sensor modes.
• The sensor modes are the Compass Mode, Barometer/Thermometer
Mode, and Altimeter Mode.
2. Place the watch on a flat surface. If you are wearing the watch, make
sure that your wrist is horizontal (in relation to the horizon).
3. Point the 12 o’clock position of the watch in the direction you want to
measure.
4. Press Cto start the direction reading operation, which is indicated by
COMP appearing on the digital display.
• When you press C, the second hand will first point in the direction
of the C(COMP) button. This indicates the Compass Mode. After
that the second hand will point in the direction of magnetic north.
• For information about direction reading results, see “Interpreting
Direction Reading Results” (page E-35).
5. After you are finished taking direction readings, press
Dto return to
the Timekeeping Mode.

Interpreting Direction Reading Results
•When you press C,COMP appears on the digital display to indicate that direction reading has started.
•After about two seconds, the second hand moves to point to magnetic north. The digital display shows
either the angle between magnetic north and the 12 o’clock position of the watch, or one of 16 literal
direction indicators.
•The watch updates the direction reading about once every second for about 20 seconds, and then
stops. The digital display shows - - - and the second hand moves to COMP (located below the C
button) to indicate that direction readings are complete. If your want to continue taking direction
readings, press Cagain.
•Pressing Eat this time switches the digital display between the angle value and a one-, two-, or
three-character literal direction indicators.
•The Auto Light switch is disabled during the 20 seconds that direction readings are being taken.
•The following table shows the meanings of the abbreviations used for the literal direction indicators that
appear on the digital display.
Direction Meaning Direction Meaning Direction Meaning Direction Meaning
NNorth NNE North-
northeast NE Northeast ENE East- northeast
EEast ESE East-
southeast SE Southeast SSE South- southeast
SSouth SSW South-
southwest SW Southwest WSW West- southwest
WWest WNW West-
northwest NW Northwest NNW North- northwest
•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.
E-36
•If the second hand is indicating 12 o’clock (north), the digital display will show an upwards pointing
white on black arrow.
• The small scale in the center of the watch face is a direction scale (page E-34). You can use the
direction scale to get an idea of how many degrees the 12 o
’ clock position of the watch is (clockwise)
from the northerly indication of the second hand. The direction scale is marked in 10-degree increments.
Some watch models may not have a direction scale.
•Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in
large measurement error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
•Any ongoing direction measurement 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 measurement operation resumes for its remaining duration after the operation
that caused it to pause is finished.
•For precautions that should be observed when using the Compass Mode, see “Compass Precautions”
(page E-43).
Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off. There are three different calibration methods available: magnetic declination correction,
bidirectional calibration, and northerly calibration.
•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 specified
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°.
E-37
•Bidirectional Calibration and Northerly Calibration
Bidirectional calibration and northerly calibration calibrate the accuracy of the bearing sensor in relation
to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed
to magnetic force. This type of calibration should be used if the watch becomes magnetized for any
reason. With northerly calibration, you “teach” the watch which way is north (which you have to determine
with another compass or some other means).
Important!
The more correctly you perform bidirectional calibration, the better the accuracy of the bearing sensor
readouts. You should perform bidirectional calibration whenever you change environments where you
use the bearing sensor, and whenever you feel that the bearing sensor is producing incorrect readings.
To perform magnetic declination correction
1. In the Compass Mode, hold down Euntil each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Use A(East) and C(West) to change the settings.
• The following explains magnetic declination angle direction settings.
0°: 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.

• To return the magnetic declination to its initial factory default setting, press
Aand Cat the same
time. This will cause OFF to appear on the digital display. After about one second, the magnetic
declination will change to 0 degrees.
• The illustration on page E-37 shows declination angle direction value and the angle value you should
select when a map shows a magnetic declination of “West 1°”.
3. When the setting is the way you want, press Eto exit the setting screen.
Precautions about bidirectional calibration
•You can use any two opposing directions for bidirectional calibration. You must, however, make sure
that they are 180 degrees opposite each other. Remember that if you perform the procedure
incorrectly, you will get wrong bearing sensor readings.
•Do not move the watch while calibration of either direction is in progress.
•You should perform bidirectional calibration in an environment that is the same as that where you plan
to be taking direction readings. If you plan to take direction readings in an open field, for example,
calibrate in an open field.
To perform bidirectional calibration
1. In the Compass Mode, hold down Euntil each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Press Dto display the bidirectional calibration screen.
• At this time, the digital display will show -1- to indicate that the watch
is ready to calibrate the first direction.
E-39
3. Place the watch on a level surface facing any direction you want, and press Cto calibrate the first
direction.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show -2-. This means that the watch is ready for calibration of
the second direction.
• Calibration takes about 13 seconds. Do not move the watch while calibration is being performed.
4. Rotate the watch 180 degrees.
5. Press Cagain to calibrate the second direction.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show OK and then change to the Compass Mode screen (- - -).
To perform northerly calibration
Important!
If you want to perform both northerly and bidirectional calibration, perform bidirectional calibration first,
and then perform northerly calibration. This is necessary because bidirectional calibration cancels any
existing northerly calibration setting.
1. In the Compass Mode, hold down Euntil each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Press Dtwice to display the northerly calibration screen.
• At this time, -n- (north) appears on the digital display.
3. Place the watch on a level surface, and position it so that its 12 o’clock position points north (as
measured with another compass).
