About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the digital 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 (while settings are flashing on the display), while an alarm is sounding, or while a silent alert operation is being performed.

•Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the digital 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.

•When auto receive is turned on, the watch receives the calibration signal for two to six minutes each day when the digital 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 shown on the digital display. The receive operation will be performed whenever the digital display shows 2:00 AM, 4:00 AM and 6:00 AM, regardless of whether or not the displayed 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.

Setting the Digital 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.

•If the analog time does not match the digital time for any reason, use the procedure described under “To adjust the analog time” to match the analog setting to the digital setting.

•Whenever you need to adjust both the digital and the analog time settings manually, make sure you adjust the digital setting first.

•Depending on how much the hands have to move in order to adjust to the digital time, it may take some time before the analog hands stop moving.

To adjust the analog time

Current time in the selected city code

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

•For full information on city codes, see the “City Code Table”.

•The current time for all city codes in the World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on the your Home City time setting.

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

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

•See “City Code Table” for a complete list of available city codes.

•Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.

Analog Timekeeping

The analog time of this watch is synchronized with the digital time. The analog time setting is adjusted automatically whenever you change the digital time.

To view the time in another city code

While in the World Time Mode, press D to scroll through the city codes (time zones) to the east or A to scroll to the west.

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

To toggle a city code time between standard time and Daylight Saving Time

1.In the World Time Mode, use A and D to display the city code (time zone) whose standard time/Daylight

Saving Time setting you want to change.

2. Press B to toggle Daylight Saving Time (DST displayed) and standard time (DST not displayed).

• The DST indicator is on the display whenever you display a city code for which Daylight Saving Time is turned on.

•Note that the DST/Standard Time setting affects only the currently displayed city code. Other city codes are not affected.

•Daylight Saving Time (DST) advances the time setting by one hour from Standard Time. Remember that the not all countries or even local areas use Daylight Saving Time.

•Note that you cannot use the World Time Mode to change the DST ON/OFF setting of the Home City code you currently have selected 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 code time.
