Chinese Time Calibration Signal
The Chinese time calibration signal (BPC) is maintained by the National Time
Service Center (http://www.ntsc.ac.cn/) of the Chinese Academy of Sciences,
and is transmitted from a transmitter (68.5 kHz) located in Shangqiu. The time
data of the Chinese time calibration signal is maintained by the National Time
Service Center.
• Note that transmission of the calibration signal may be interrupted
occasionally due to maintenance, lightning, etc.
Operation Guide 5019
The electricity generated by the solar cell of the
watch is stored by a built-in battery. Leaving or
using the watch where it is not exposed to light
causes the battery to run down. Make sure the
watch is exposed to light as much as possible.
• When you are not wearing the watch on your
wrist, position the face so it is pointed at a
source of bright light.
• You should try to keep the watch outside of
your sleeve as much as possible. Even if the
face of the watch is only partially blocked from
light, charging will be reduced significantly.

Your watch receives a time calibration signal and
updates its time setting accordingly.
• This watch is designed to receive the time
calibration signal transmitted from Shangqiu
City, Henan Province, China (Call Sign: BPC,
Frequency: 68.5 kHz).
• As of July 2007, China does not use Daylight
Saving Time (DST). If China does go to the
Daylight Saving Time system in the future,
some functions of this watch may no longer
operate correctly.
• See the information under "Signal Reception
Troubleshooting" if you experience problems
with time calibration signal reception.
• The actual level at which some functions are disabled depends on the
watch model.
• Be sure to read "Power Supply" for important information you need to
know when exposing the watch to bright light.

If the analog hands aren't moving, it means that the power saving mode has
stopped them to save battery power.
• See "Power Saving" for more information.

Current Time Setting
This watch adjusts its time setting automatically in accordance with a time
calibration signal. You also can perform a manual procedure to set the time
and date, when necessary.
• When using the watch in an area the Chinese time calibration signal does
not reach or outside the China time zone (GMT +8), you will need to adjust
the watch's time setting manually. For information about adjusting the time
setting manually, see "Timekeeping".
• The watch interprets any manual change of the time setting by more than
30 minutes or manual switching between Standard Time and Daylight
Saving time as a change to another time zone. At this time the watch turn
off auto receive automatically.
• If you successfully perform a manual receive operation after auto receive is
turned off automatically by one of the events described above, the watch
will turn auto receive back on automatically.
• Even if the time calibration signal is received correctly, there are some
times when the analog hands may not indicate the correct time. If this
happens, use the procedures under "Adjusting the Home Positions" to
check the home positions of the hands, and make adjustments as required.
• Button operations are indicated using the
letters shown in the illustration.
• Each section of this manual provides you with
the information you need in order to perform
operations in each mode. Further details and
technical information can be found in the
"Reference" section.
