Use the procedure under “To confi gure Home City settings” to confi gure your Home City and daylight saving time settings.
Important!
Proper time calibration signal reception, and World Time Mode and Sunrise/Sunset Mode data depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you confi gure these settings correctly.
3. Set the current time.
To set the time using a time calibration signal
See “To get ready for a receive operation”.
To set the time manually
See “Confi guring Current Time and Date Settings Manually”.
The watch is now ready for use.
For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic
Timekeeping”.

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.
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
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 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.
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
if its face is blocked by your sleeve even only partially.
Power Levels
You can get an idea of the watch’s power level by observing the battery power indicator on the display.

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, reconfi gure 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.
Power Recovery Mode
Performing multiple sensor, illumination, or beeper operations during a short period may cause all of
the battery power indicators (H,M, and L) to start fl ashing on the display. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.
Battery power will recover in about 15 minutes. At this time, the battery power indicators (H,M,L) will
stop fl ashing. This indicates that the functions listed above are enabled again.
If all of the battery power indicators (H,M,L) are fl ashing and the C (charge) indicator also is fl ashing,
it means the battery level is very low. Expose the watch to bright light as soon as possible.
Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it suffi ciently. This is indicated when all of the battery power indicators (H,M,L) are fl ashing.
Frequent fl ashing of all of the battery power indicators (H,M,L) probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.

Power Saving
When turned on, 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”.
Elapsed Time in Dark Display Operation

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.
The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.
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.

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” 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:
LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainfl ingen (Germany)
HKG, BJS Shangqiu City (China)
TPE, SEL, TYO Fukushima (Japan), Fukuoka/Saga (Japan)

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.
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. Mainfl ingen (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) Shangqiu (China) transmitter: 500 kilometers (310 miles)
As of January 2009, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.
To get ready for a receive operation
1. Confi rm that the watch is in the Timekeeping Mode. If it isn’t, use D to enter the Timekeeping Mode.
2. The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing

Auto Receive
With Auto Receive, the watch performs the receive operation each day automatically up to six times (up
to fi ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.
When a calibration time is reached, the watch will perform the receive operation only if it is in the
Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is reached while you are confi guring settings.
You can use the procedure under “To turn auto receive on and off” to enable or disable auto receive.

Radio-controlled Atomic Timekeeping Precautions
Strong electrostatic charge can result in the wrong time setting.
Even if a receive operation is successful, certain conditions can cause the time setting to be off by up
to one second.
The watch is designed to update the date and day of the week automatically for the period January 1,
2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.
If you are in an area where signal reception is not possible, the watch keeps time with the precision
noted in “Specifi cations”.
The receive operation is disabled under any of the following conditions.
– While power is at Level 3 (L) or lower – While the watch is in the power recovery mode – While a sensor operation is being performed – When the watch is in the function sleep state (“Power Saving”) – While a countdown timer operation is in progress
A receive operation is cancelled if an alarm sounds while it is being performed.

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.
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 fi nished.
See “Digital Compass Precautions” for important information about taking direction readings.
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 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°.
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.

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 fi eld, for example, calibrate in an open fi eld.

1. In the Digital Compass Mode, hold down E until the current magnetic declination settings start to fl ash on the display. This is the setting screen.
Before the magnetic declination settings start to fl ash, the message
SET Hold will appear on the display. Keep E depressed u ntil SET Hold disappears and the magnetic declination settings start to
fl a s h .
2. Use A (East) and C (West) to change the settings.
The following explains magnetic declination angle direction settings.
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 valu e within the ran ge of W 90° to E 9 0° with
these settings.
You can turn off (OFF) magnetic declination correction by pressing
A
and C at the same ti me.
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.
3. When the setting is the way you want, press E to exit the setting screen.
