Rechargeable battery

The electricity generated by the solar cell of the watch is stored by a built-in battery. Leaving or

using the watch where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

• When you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.

• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is only partially covered.

Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

• This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.

• The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see “To specify your Home City” below.

• When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See settings.

• The U.S. time calibration signal can be picked up by the watch while in North America. The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico.

• Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You also can perform manual receive or you can set the time manually.

• The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Time Calibration Signal Reception” and “Transmitters”.

• See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.

• You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

• Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HNL (Honolulu), and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off”.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

• Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

• Manual Receive

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

Important!

• When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

12 o’clock

• Make sure the watch is facing the right way.

• Proper signal reception can be difficult or even impossible under the

conditions listed below.

Inside or among buildings

• Signal reception normally is better at night than during the day.

• Time calibration signal reception takes from two to seven minutes, but in

some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

• The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

LIS, MAD, ROM, STO, MOW

CHI, NYC, YVR, YEA, MEX,

* The areas covered by the HNL, ANC, and MOW city codes are quite far

from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception.

• Calibration signal reception is disabled while a countdown timer/target time operation is in progress.

Operation Guide 3150

Note

• When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.

• Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

• The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within seven minutes before or after the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

About the Signal Strength Indicator

The signal strength indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest. The signal strength indicator is displayed while an auto or manual receive operation is in progress.

Signal strength indicator

Weak

(Level 1)

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the signal strength indicator to indicate signal strength.

• Use the signal strength indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.

• Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 3 signal strength indicator will remain on the display in all modes. The Level 3 signal strength indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

• The Level 3 signal strength indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.

• The Level 3 signal strength indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 3 signal strength indicator disappears from the display each day when the first auto receive operation of the day is performed.
