Keep the watch exposed to bright light

Bright Light

Solar cell

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will cause some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light. Battery discharges in the dark.

General Guide

• Press C to change from mode to mode.

• In any mode, press L to illuminate the display.

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.

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

• When using the watch in an area that is outside of the range of the transmitters in Rugby and Mainflingen, you need to adjust the time manually as required. See “Timekeeping” for information about manual settings.

To set your Home City

City code

Important!

• 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 can also perform manual receive or you can set the time manually.

• If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.

This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.

• This watch is designed to pick up the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany.

Current Time Setting

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

1. In the Timekeeping Mode, hold down A until the city

code starts to flash, which indicates the setting screen.

2. Use D(east) and B(west) to select the city code you

want to use as your Home City.

• The following are the city codes for major cities in the

Western Europe time zones.

LON: London PAR and BER: Paris, Berlin, Milan, Rome,

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

Auto receive attempts to receive the time calibration signal automatically up to six times. 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. Make sure there are no metal objects nearby.

• The watch should not be on its side or facing the wrong way.

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

below.

Inside or among buildings

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

•

Time calibration signal reception takes from two to six minutes, but in some cases it can take as long as 12 minutes. Take care that you do not perform any button operations or move the watch while time calibration signal reception is in progress.

Operation Guide 2911

• This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany.

Reception Ranges

Rugby

Mainflingen

• At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interference may also cause problems with reception.

• Even when the watch is within the reception range of the transmitter, signal reception is impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.

• Signal reception is affected by weather, atmospheric conditions, and seasonal changes.

• See the information under “Signal Receive Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

When auto receive is turned on, the watch attempts to receive the time calibration signal automatically up to six times. The start times of the auto receive operations depend on the current Home City and DST settings.

• If all of the first three reception operations fail, the watch automatically performs a fourth receive operation.

• If any of the remaining receive operations (4, 5, or 6) is successful, any remaining receive operations are skipped.

• Auto receive is performed in accordance with the Timekeeping Mode time.

Note

• Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or if a setting screen (a screen with a flashing setting) is on the display.

• Auto receipt 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.

• When auto receive is turned on, the watch receives the calibration signal for two to

six minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within six minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the time kept 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 Timekeeping Mode time is actually the correct time.

• If more than one auto receive is successful, the watch uses the data from the last

successful receive to adjust settings. When only one reception is successful, the watch uses the data of the successful reception.

About the Receiving Indicator

The receiving 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.

Receiving indicator

• Even in an area where signal strength is strong, it takes about 10 seconds for signal

reception to stabilize enough for the receiving indicator to indicate signal strength.

• Use the receiving 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 4 receiving indicator will remain on the display in all modes. The Level 4 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

• The Level 4 receiving 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 4 receiving indicator indicates that at least one of the auto calibration

signal receive operations was successful. Note, however, that the Level 4 receiving indicator disappears from the display each day when the second auto receive operation of the day is performed.
