•
This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. Signal reception is possible
within the area represented by a circle with a radius of about 1,500 kilometers.
•
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 interference
may also cause problems with reception.
•
See the information under “Signal Receive 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 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 is on whenever the transmitter mode setting is anything other than
OFF
. See “Transmitters” for more information.
•
The auto receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
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
five minutes everyday when the time in the Timekeeping Mode reaches each of the
calibration times. Do not perform any button operation within five 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 time kept in 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.
•
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.
•
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.
(Level 1) Weak
Strong (Level 4)
Receiving indicator
•
The Level 4 receiving indicator is displayed only when the watch is able to
successfully receive both time and date data. It does not appear when only time data
is received.
•
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.
To perform manual receive
1. Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
•
Note that signal reception is poor when the 12 o’clock
side of the watch is not facing towards a window.
2. In the Timekeeping Mode (Current Time screen), hold
down
D
for about two seconds until the watch beeps.
3. Release
D
and the message
RC!
appears to indicate
that signal reception has started.
•
Time calibration signal reception takes from two to five
minutes. Take care that you do not perform any button
operations or move the watch during this time.
Receiving indicator
•
After signal reception is complete, the display of the watch changes to the Last
Signal screen.
Note
•
To interrupt a receive operation and return to the Timekeeping Mode, press
D
.
•
If the receive operation is unsuccessful, the message
ERR
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
ERR
screen to the normal
timekeeping screen by pressing
D
.

•
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 Home City time.
Time Recorder
The Time Recorder lets you store up to 30 records of the current time (month, day,
hour, minutes, seconds, and DST on/off setting) with the touch of a button. One way
you can use the Time Recorder is to record the start time and the end time of a
particular event.
To record a Time Recorder time
1. Enter the Timekeeping Mode.
2. Hold down
B
for about one second to record the Home City time (month, day,
hour, minutes, seconds, and DST on/off setting).
•
The recorded time flashes for about two seconds, and then it is assigned a record
number. After that, the Timekeeping Mode screen appears.
•
Records are assigned numbers sequentially from
#01
through
#30
.
•
Storing a new time record when there are already 30 records stored in memory
automatically deletes record
#01
, shifts the remaining records upwards by 1, and
stores the new record as
#30
.
To recall Time Recorder times
1. Enter the Time Recorder Mode.
• If you recorded a new Time Recorder time since you
last entered the Time Recorder Mode, the newest
record appears first. If you have not recorded a new
time, the record you were viewing when you last
exited the Time Recorder Mode appears first.
