Operation Guide 5036
• At distances further than about 500 kilometers from the Shangqiu (China)
transmitter, signal reception may not be possible during certain times of year or
times of day. Radio interference may also cause problems with reception.
• 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 starts to receive the time calibration signal automatically when the time in
the Timekeeping Mode reaches 1:00 a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00
a.m. each day (calibration times). When any auto receive is successful, the remaining
auto receive operations are not performed.
Note
• Auto receive normally is performed when a calibration time is reached while the
watch is in the Timekeeping Mode and Dual Time Mode. The receive operation is not
performed if you are performing a button operation.
• 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 receive the signal easily.
• The watch receives the calibration signal for two to seven minutes when the time in
the Timekeeping Mode reaches a calibration time. 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 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.
• The 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.
• If signal reception is unstable during reception, the
R (READY)
W (WORK)
second hand may move between W (WORK) and R
(READY) .
Y (YES)
• The hour and minute hands continue to keep time
normally.
• Time calibration signal reception takes from two to
seven 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). Five seconds later, the hands will move to the
N (NO)
correct time.
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press any
button.
• If reception is not successful, the second hand will move to N (NO). Five seconds
later, the second hand will resume normal operation, without any adjustment of the
hand setting.
• If the second hand is pointing to Y (YES) or N (NO), you can return to the
Timekeeping Mode by pressing A.
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.
• Whenever the watch successfully performs any signal
receive operation from 1:00 a.m. onwards, the 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 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
second hand will move to N (NO).

• Enter the Timekeeping or Dual
Time Mode and try again.
• Check to make sure the watch

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

3. Check the elapsed time.
• Press A to reset the stopwatch. Resetting the stopwatch causes the stopwatch
1/20-second hand and the second hand to move to 12 o'clock, and the digital display
to reset to zero.
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
UTC offset 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.

To view the time in another time zone
While in the Dual Time Mode, press B to scroll eastward through time zones.
• When you release B, the hands will move to the current time in that time zone after
about one second.
• 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.
To toggle a time zone between Standard Time and Daylight Saving Time
1. In the Dual Time Mode, use B to display the time zone
whose Standard Time/Daylight Saving Time setting you
want to change.
2. Hold down A to toggle between Daylight Saving Time
(DST indicator displayed) and Standard Time (DST
indicator not displayed).
• Turning on DST causes the UTC offset value to be
increased by one.
