About the Receive Indicator

The receive 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.

Weak Strong

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

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

•The receive indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The receive indicator does not appear if signal reception was unsuccessful or after manual adjustment of the current time setting.

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM and 6:00 AM each day (calibration times).

Note

• The auto receive operation is performed only if the watch is in the Timekeeping or

World Time Mode when one of the calibration times is reached.

It is not performed if a calibration time is reached while you are making settings

•The auto receive setting is used for time calibration signal reception only. See “About Auto Receive” for details.

(while settings are flashing on the display), while an alarm is sounding.

• 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 easily receive the signal.

• The receive indicator indicates that either the 2:00 AM, 4:00 AM, or 6:00 AM

calibration signal reception was successful. Note, however, that the receive indicator

is cleared from the display at 3:00 AM each day.

• If you do not see the receive indicator except for the above reason, it means there

was some problem with the calibration reception operation. Either perform reception

manually, or make sure the watch is set up properly to receive the time calibration

signal for the next automatic reception time.

• Though this watch is designed to receive both time data (hour, minutes, seconds)

and date data (year, month, day), certain signal conditions can limit reception to time

data only.

• The receive indicator ( ) appears only when the watch is able to successfully

receive both time and date data. It does not appear when only time data is received.

The World Time shows the current time in 30 cities (29 time zones) around the world.

•If the current time shown for a city is wrong, check your Timekeeping Mode time and Home City settings and make the necessary changes.

•You can change the DST (Daylight Saving Time)/ Standard Time settings for each city code in the Timekeeping Mode.

•The watch will perform a signal receive operation even if it is in the World Time Mode when a calibration time is reached. If this happens, the World Time Mode time settings will be adjusted in accordance with the Timekeeping Mode’s Home City time.

•All of the operations in this section are performed in the World Time Mode, which you enter by pressing C.

When time and date data is received: Receive indicator ( ) appears.

When time data only is received: Receive indicator ( ) does not appear.

• Normally, the signal reception date shown by the Last Signal screen is the date data

included in the received time calibration signal. When only time data is received,

however, the Last Signal screen shows date as kept in the Timekeeping Mode at the

time of signal reception.

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

six minutes each day when the Timekeeping Mode time reaches 2:00 AM, 4:00 AM

and 6:00 AM. Do not operate any of the watch’s buttons within six minutes prior to or

following 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 2:00 AM, 4:00 AM and 6:00 AM, regardless of whether or not the

Timekeeping Mode time is actually the correct time.

• When two or three receptions are successful, the watch uses the data of the last

reception for calibration. When only one reception is successful, the watch uses the

data of the successful reception.

To turn auto receive on and off

1. In the Timekeeping Mode, hold down Auntil the current auto receive on/off setting to flash, which indicates the setting screen.

2. Press Dto toggle auto receive on (ON) and off (OF).

The Alarm Mode gives you a choice of four one-time alarms and one snooze alarm. One of the one-time alarms functions as a “target alarm,” which counts the time remaining from the current Timekeeping Mode time to the target alarm time.

Also use the Alarm Mode to turn the Hourly Time Signal (SIG) on and off.

•There are five alarms numbered AL1 through AL3, TAL,and SNZ. You can configure SNZ as a snooze alarm only. Alarms AL1 through TAL (target alarm) can be used as one-time alarms only.

•Alarm settings (and Hourly Time Signal settings) are

available in the Alarm Mode, which you enter by pressing C.

Setting the Time and Date Manually

Make sure you select your Home City code (the city code whose time and date you are setting) before change the current time and date settings. World Time Mode times are all displayed in accordance with the Timekeeping Mode settings. Because of this, World Time Mode times will not be correct if you do not select the proper Home City code before setting the time and date in the Timekeeping Mode.

To set the current time and date manually

1. In the Timekeeping Mode, hold down Auntil the current auto receive on/off setting to flash, which indicates the setting screen.
