• Make sure the watch is facing the right way.
• Proper signal reception can be difficult or even impossible under the conditions listed
below.

• Signal reception normally is 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 (Anthorn) time calibration signals.
See “Transmitters” for more information.

• Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310
miles)
• Even when the watch is within the reception range of the transmitter, signal
reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
About Auto Receive
The watch receives the time calibration signal automatically up to six times a day.
When any auto receive is successful, the remaining auto receive operations are not
performed. The reception schedule (calibration times) depends on your currently
selected Home Time Zone, and whether standard time or Daylight Saving Time is
selected for your Time Zone.
Note
• Auto receive is turned on whenever +0.0, +1.0, or +2.0 (+1.0, +2.0, or +3.0 while
DST is turned on) is selected as the Home Time Zone.

Note
• Calibration signal reception is performed automatically whenever a calibration time is
reached while the watch is in the Timekeeping Mode or Dual Time Mode. Note,
however, that auto receive is not performed if a calibration time is reached in the
following cases:
While an alarm is sounding
While a button is depressed
• Auto receive 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 receive the signal easily.
• The watch receives the calibration signal for two to 14 minutes every day when the
time in the Timekeeping Mode reaches each of the calibration times. Avoid
performing any button operation within 14 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 in the
Timekeeping Mode.
To perform manual receive
1.Place the watch on a stable surface so its 12 o’clock
side is facing towards a window.
2.In the Timekeeping Mode, hold down A for about two
seconds until the watch beeps.
3.The stopwatch second hand will move to R (READY) to
indicate that the watch is setting up for time calibration
reception.
• The second hand will move to W (WORK) and stay there
while actual reception is in progress.
• The hour and minute hands continue to keep time
normally.
• 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.
• If reception is successful, the second hand will move to
Y (YES). One minute later, the hands will move to the
correct time.
W (WORK)
R (READY)
Y (YES)
N (NO)
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press any
button.
• If reception is not successful, the stopwatch second hand will move to N (NO).
One minute later, the stopwatch second hand will resume normal operation, without
any adjustment of the hand setting.
• If the stopwatch second hand is pointing to Y (YES) or N (NO), you can return to the
Timekeeping Mode by pressing any button.
Viewing the Latest Signal Reception Results
You can use the procedure below to check whether or not the last signal receive 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 since midnight, the stopwatch second
hand will move to Y (YES). If the watch has been unable
to receive any signal successfully, the second hand will
move to N (NO).
• The watch will return to the Timekeeping Mode after five
seconds.
• 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
second hand will move to N (NO).
Signal Reception Troubleshooting
Check the following points whenever you experience problems with signal reception.
• You changed the time setting
manually.
•
You performed some button operation
during the auto receive operation.
• Signal reception results are reset
when the first auto receive
operation of the day is performed.
• The Home Time Zone setting is not
correct for the area where you are
using the watch.
• The home position of the hands is
off.
The
stopwatch
second hand
is pointing at
N (NO).

following signal
reception.
• Perform manual signal
receive or wait until the next
auto signal receive operation
is performed.
• Check to make sure the
watch is in a location where it
can receive the signal.
• Select the correct Home
Time Zone.
• Enter the Hand Setting Mode
and adjust the home position.
What you should doProblem Probable Cause
• For further information, see “Important!” under “Time Calibration Signal Reception”
and “Radio-controlled Atomic Timekeeping Precautions”.
Dual Time
The Dual Time Mode lets you view the current time in 29
time zones around the world.
• Time zones are indicated on the digital display by their
GMT differential values.
• For full information on time zones, see the “Time Zone
Table”.
• The watch will perform a signal receive operation even if
it is in the Dual Time Mode when a calibration time is
reached. If this happens, the Dual Time Mode time
settings will be adjusted in accordance with the current
time in the Timekeeping Mode’s Home Time Zone.
• All of the operations in this section are performed in the
Dual Time Mode, which you enter by pressing C.

Stopwatch
The stopwatch lets you measure elapsed time.
• The display range of the stopwatch is 59 minutes, 59.99
seconds.
• Entering the Stopwatch Mode causes the second hand,
the stopwatch minute hand and stopwatch 1/20 second
hand to move to their 12 o’clock positions.
• 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.
• All of the operations in this section are performed in the
Stopwatch Mode, which you enter by pressing C.
Stopwatch 1/20 second hand
* This hand rotates and indicates
the second count during the first
60 seconds.

To measure elapsed time
1. Press B to start the stopwatch.
2. Press B to stop the stopwatch.
• You can resume the measurement operation by pressing B again.
• The 1/20 second hand rotates during the first 60 seconds only, and then stops.
When elapsed timing is stopped (by pressing B), this hand jumps to the 1/20
second indication (which is kept internally).
3. Check the elapsed time.
• Press A to reset the stopwatch.
To view the time in another time zone
While in the Dual Time Mode, press B to scroll eastward through time zones.
• The hands will move to the current time in that time zone after about one second
after you release B.
• If the current time shown for a time zone is wrong, check the Timekeeping Mode
time setting and your Home Time Zone setting, and make the necessary changes.
