Viewing the Latest Signal Reception Results
You can use the procedure below to check whether or not the last signal receive operation was successful.
To check the latest signal reception results
In the Timekeeping Mode, press A.
• If the watch was able to perform a successful signal receive operation during the last receive period, the stopwatch second hand will move to Y (YES).

The Tide Graph calculates and graphically represents current tide conditions in your Home City or a port city in the vicinity of the Home City based on longitudes, lunar day length, and lunitidal interval preset in watch memory, and on high tide times specified by you.

• The watch will return to the Timekeeping Mode after five seconds or when you press A.
• The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day.
• If you adjust the time or date setting manually, the stopwatch second hand will move to N (NO).

To specify the current time as the high tide time
In the Tide Graph Mode, hold down Bfor about two seconds until the watch beeps twice.
• This will set the current time as the high tide time, and cause the day of the week hand to move to the high tide position.

To start an elapsed time operation while in the Stopwatch Mode
1.In the Stopwatch Mode, press Bto start elapsed time measurement.
2.Press B to stop elapsed time measurement.
•You can restart and stop elapsed time measurement as many times as you like by pressing B.
•The 1/20 second hand rotates during the first 60 seconds only, and then stops. When elapsed timing is stopped (by pressing B), the 1/20 second hand jumps to the 1/20 second indication (which is kept internally).
3.Check the elapsed time.
•After you are finished measuring elapsed time, press D to reset the stopwatch to all zeros. The stopwatch will reset to all zeros even if you press D while elapsed time measurement is in progress.
•To return to the Timekeeping Mode, press D while the stopwatch is reset to all zeros.
To start an elapsed time operation while in the Timekeeping Mode
1.In the Timekeeping Mode, press Bto start elapsed time measurement.
•After pressing Bin the Timekeeping Mode, elapsed time measurement will not start for about one second.
•The elapsed time operation will not start if you press Bin the Timekeeping Mode while either of the following conditions exists.
