•Signal reception is normally better at night than during the day.
•Time calibration signal reception takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.
•When within range of the applicable transmitter, this watch can receive either the Germany (Mainflingen) or England (Rugby) time calibration signals. See “Transmitters” for more information.

•Under good reception conditions, signal reception is possible within a radius of about 1,500 kilometers from a transmitter.
•At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.
•See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
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 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive operation at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful.
Note
• Auto receive turns on automatically whenever you select +1.0 or +0.0 as your Home |
Time Zone. For information about turning off auto receive, see “To select the |
transmitter mode”. |
• The auto receive operation is performed only if the watch is in the Timekeeping |
Mode or Dual Time Mode when one of the calibration times is reached. It is not |

•When a receive operation starts, the second hand will
move at high speed to the 12 o’clock position where it will stop until the receive operation is complete.
•Time calibration signal reception takes from two to seven minutes, but in some cases it can take up to 14 minutes. Take care that you do not perform any button operations or move the watch during this time.
•After signal reception is complete, the watch beeps and the display of the watch changes to the last signal screen.
Note
•To interrupt a receive operation and return to the Timekeeping Mode, press B.
•If the receive operation is unsuccessful, – – – – – – 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 – – – – – – screen to the normal timekeeping screen by pressing B.

performed if a calibration time is reached while an alarm is sounding, or while you |
are configuring settings (while settings are flashing on the display). |
• 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. |
• When auto receive is turned on, the watch receives the calibration signal for two to |
seven minutes everyday when the time in the Timekeeping Mode reaches each of |
the calibration times. Do not perform any button operation within seven minutes |
before or after any one of the calibration times. Doing so can interfere with correct |
calibration. |
• Remember that reception of the calibration signal depends on the current time on |
the digital display. The receive operation will be performed whenever the display |
shows any one of the calibration times, regardless of whether or not the displayed |
time is actually the correct time. |

The stopwatch lets you measure elapsed time, lap times, split times, and two finishes. Stopwatch times are also stored in memory.
•The display range of the stopwatch is 59 minutes, 59.99 seconds.
•All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C.
•Entering the Stopwatch Mode causes the second hand and battery level dial hand to move to the 12 o’clock position.
•In the Stopwatch Mode, the second hand shows the seconds of the elapsed time measurement, the battery level dial shows elapsed minutes, and the stopwatch 1/20 second dial shows elapsed 1/20 second.
When two, three, four, or five 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. |
About the Receiving Indicator
The receiving 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.

Receiving indicator
•Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.
•Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.
•The Level 4 receiving indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The Level 4 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.
•The Level 4 receiving indicator indicates that at least one of the calibration signal receive operations was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 3:00 a.m. each day.

Note
•“Lap time” is the time spent to cover a specific segment of a race, such as one lap around a track. “Split time” is the time spent from the beginning of a race up to a certain point.
•The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.
•The stopwatch measurement operation continues even if you exit the Stopwatch Mode.
•The hand of the stopwatch 1/20 second dial revolves for the first minute of each elapsed time operation. After that, it stops automatically at the 12 o’clock position. If you exit the Stopwatch Mode while an elapsed time operation is in progress, the 1/20 second hand will revolve for the first minute after you
•For information about how stopwatch times are stored in memory, see “Memory Management”.
•You can adjust the positions of the stopwatch 1/20 second dial and battery level dial hands if they do not align exactly with the 12 o’clock position. See “Adjusting Dial Hand Positions” for more information.
To measure elapsed time
1.Press Bto start the stopwatch.
2.Press Bagain to stop the stopwatch.
• You can resume the measurement operation by pressing B.
