Operation Guide 2762
•The current time setting in accordance with the time calibration signal takes priority over any time settings you make manually.
•The watch is designed to automatically update the date and day of the week for the period January 1, 2000 to December 31, 2099. Setting of the date by the time calibration signal cannot be performed starting from January 1, 2100.
•This watch can receive signals that differentiate between leap years and
•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.
•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 the date as kept in the Timekeeping Mode at the time of signal reception.
•If you are in an area where proper time calibration signal reception is impossible, the watch keeps time within ±15 seconds a month at normal temperature.
•If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your Home Time Zone value and DST (summer time) settings, and transmitter mode setting. The following are the initial factory defaults for these settings.
To recover from the sleep state

Adjusting Dial Hand Positions
You can use the procedure in this section to adjust the position of the stopwatch 1/20 second dial hand and the battery level dial hand whenever they do not align with the 12 o’clock position when you enter the Stopwatch Mode.

Transmitter mode | W 60 (U.S. signal) |
Transmitters
This watch is able to receive time calibration signals transmitted in the United States (Fort Collins, Colorado) and Japan (Fukushima or Fukuoka/Saga). Selecting one of the time zones as your Home Time Zone automatically configures the watch to receive the applicable time calibration signal.
GMT Differential value | Transmitter | Frequency | |
| Fort Collins, Colorado | 60kHz | |
+9.0 | Fukushima | 40kHz | |
Fukuoka/Saga | 60kHz | ||

Battery level dial
Important!
Never move the battery level dial hand to any position other than 12 o’clock. If you do, it will not correctly indicate the battery power level.
To adjust dial hand positions
1.In the Timekeeping Mode, press C five times to enter the Hand Setting Mode.
2.Hold down A until – 0 0 – starts to flash, which indicates the analog setting screen.
3.Press Ato display the dial hand setting screen.
•The dial hand setting screen shows 00:00.00, with the two zeros on the far right flashing. This indicates that the stopwatch 1/20 second dial is selected for adjustment.
•When you have +9.0 (Japan) selected as your Home Time Zone, you can specify either the Fukushima or Fukuoka/Saga transmitter, or you can configure the watch to automatically select the transmitter that has the strongest signal.
•Selecting OFF for the transmitter mode setting disables auto receive.

• The following are the available transmitter mode settings when +9.0 (Japan) is selected as the Home Time Zone.
A: Automatic selection of the Fukushima or Fukuoka/Saga signal
J 40: Reception of the Fukushima signal
J 60: Reception of the Fukuoka/Saga signal
OFF: Auto receive off
4.Press A to exit the setting screen and return to the last signal screen.
• If you want to the return to the Timekeeping Mode screen, press B.
• Signal reception can take up to 14 minutes when the A option is selected.
Timekeeping
•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.
•The year can be set in the range of 2000 to 2099. The day of the week is calculated automatically in accordance with the date.
•The watch’s
•The current time for all time zones in the Timekeeping Mode and Dual Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential of each zone, based on your Home Time Zone time setting.
•GMT differential is calculated by this watch based on Universal Time Coordinated (UTC*) data.

Power Saving
When turned on, Power Saving automatically enters a sleep state whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.
•There are actually two sleep state levels: “display sleep” and “function sleep”.
Elapsed Time in Dark | Operation |
3 to 4 days | Digital display off, but all functions enabled |
(Display Sleep) |
|
|
|
8 days or more | • Digital display off |
(Function Sleep) | • All functions, including analog timekeeping, disabled |
| • Internal timekeeping maintained |
|
|
• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
4.Press Dto advance the hand of the stopwatch 1/20 second dial one step, until it is aligned with the 12 o’clock position.
5.After the 1/20 second dial hand is aligned properly, press C.
•This causes the two far left zeros of the 00:00.00 figures to flash, which indicates that the battery level dial is selected for adjustment.
6.Press Dto advance the hand of the battery level dial one step, until it is aligned with the 12 o’clock position.
7.Press Ato exit the setting screen.
•To return to the Timekeeping Mode, press C.
Illumination Precautions
•The illumination provided by the light may be hard to see when viewed under direct sunlight.
•Illumination automatically turns off whenever an alarm sounds.
•Frequent use of illumination shortens the battery operating time.
Auto light switch precautions
•Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illuminate the face of the watch. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the face.
•Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the face and can run down the battery.
• Illumination may not turn on if the face of the watch is
More than 15 degrees | more than 15 degrees above or below parallel. Make | |
too high | ||
sure that the back of your hand is parallel to the ground. | ||
| ||
| • Illumination turns off after about two seconds, even if | |
| you keep the watch pointed towards your face. | |
| • Static electricity or magnetic force can interfere with | |
| proper operation of the auto light switch. If illumination | |
| does not turn on, try moving the watch back to the | |
| starting position (parallel with the ground) and then tilt it | |
| back towards your face again. If this does not work, drop | |
| your arm all the way down so it hangs at your side, and | |
| then bring it back up again. |
•Under certain conditions, illumination may not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch.
•You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
