USER’S GUIDE 2512
To perform manual time calibration signal reception
1.Place the watch on a stable surface so its top (12 o’clock side) is facing in the
general direction of the signal transmitter.
∙ Note that signal reception is poor if the watch is on its back or side.
2. In the Timekeeping Mode, hold down A for about two seconds until the watch beeps.
∙ Release A and the message receiving appears to
|
|
|
|
|
|
|
|
|
| indicate that signal reception has started. |
|
|
|
|
|
|
|
|
|
| ∙ Time calibration signal reception takes from two to six |
|
|
|
|
|
|
|
|
|
| minutes. Take care that you do not move the watch |
|
|
|
|
|
|
|
|
|
| during this time. |
|
|
|
|
|
|
|
|
|
| ∙ After signal reception is complete, the display of the |
|
|
|
|
|
|
|
|
|
| watch changes to the Last Signal screen. |
|
|

| ∙ The receive indicator indicates that the calibration time |

|
Note
∙To interrupt a receive operation and return to the Timekeeping Mode, press A.
∙If the receive operation is unsuccessful, the message ERROR! appears on the display for about one or two minutes. After that, the watch returns to the Timekeeping Mode.
∙You can also change from the Last Signal or ERROR! screen to the normal timekeeping screen by pressing A.
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 |
(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 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. |
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, press B. This causes the current auto receive on/off setting (the receive indicator) to flash, which indicates the setting screen.
2. Press Cto move the flashing in the sequence shown below to select other settings.

∙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.
World Time
∙ 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. |
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. |

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.
∙ 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, press B. This causes the current auto receive on/off setting (the receive indicator)
to flash, which indicates the setting screen.
2. Press Dto toggle auto receive on (ON) and off (OFF).
3. Press Bto exit the setting screen.
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 Ato 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 Bto 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.
∙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.
