Calibration Signal
Reception Ranges
Location
• The Japanese calibration signal (Call Sign: JJY) is maintained by
the National Institute of Information and Communications
Technology (NICT). It is transmitted 24 hours a day from the Mt.
Otakadoya transmitter (40 kHz) located in Tamura-gun,
Fukushima Prefecture, and from the Mt. Hagane transmitter (60
kHz) located on the border between Saga Prefecture and
Fukuoka Prefecture.
• The U.S. calibration signal (Call Sign: WWVB) is transmitted by
the National Institute of Standards and technology from Fort
Collins, Colorado.
This watch is designed to receive the standard time calibration
signal of Japan (JJY) or of the United States (WWVB). The signal
that is received depends on the current Home City setting.
• For information about selecting a Home City, see
“Configuring Home Time Settings”. See “World Time City
Code List” for details on city codes.
Reception is difficult and may even be impossible in the locations
described below. Avoid such locations when performing signal
reception.
• You should think of your watch operating like a radio or TV when it
is receiving the calibration signal.
The time data of the Japanese calibration signal (Call Sign:
JJY) is maintained by the Japan Standard Time Group of the
National Institute of Information and Communications
Technology (NICT). Note that transmission of the standard
wave may be interrupted occasionally due to maintenance,
lightning, etc.
For more information, visit the website of the Japan Standard
Time Group of the National Institute of Information and
Communications Technology (NICT) at the following URL.
http://jjy.nict.go.jp
• Note that the above URL is subject to change.
After the watch receives the Standard Time signal, it performs
internal calculations to determine the current time. Because of
this, there may be an error of up to one second in the
displayed time.

• Use one of these settings for
reception of the Japanese signal in
Japan or Taiwan.
Fort Collins, Colorado signal
• Use one of these settings for
reception of the U.S. signal in
North America.
• CASIO does not guarantee that the watch will be able to receive a
calibration signal correctly each day.
• Geographic contours, nearby buildings, the season, the time of
day, can even make reception impossible even when you are
within range of the transmitter.
• Best reception is possible late at night.
Among or near buildings
Inside a vehicle
(automobile, train, plane, etc.)
In a location where there is
radio interference
(construction site, airport, etc.)
Near high-voltage lines
Next to a household appliance or
office equipment (TV, speaker, fax,
PC, mobile phone, etc.)
Near mountains
If you are experiencing problems with reception, move away
from the types of locations described above to a location with
better reception, and try again.
Receiving the Calibration Signal
There are two methods you can use in order to receive the time
calibration signal.
• Auto receive (Reception is performed automatically at
midnight, 1:00, 2:00, 3:00, and 4:00 each morning.)
• Manual receive (You initiate reception using a button operation.)
• If reception is not successful for any of the normal auto receive
operations shown above, auto receive is performed one more
time at 5:00 a.m.
• The watch is set up for auto receive at the factory, so all you need to
do is to place it in a location that allows good reception each night.
■ To position the watch for optimum reception
Remove the watch from your wrist and place it somewhere so its
top (12 o’clock, where the antenna is located) is facing
approximately in the direction of the signal transmitter. Keep it
away from metal objects.
Time Required for Reception
Receive Indicator
Signal reception takes anywhere from about two to seven minutes.
In cases where receipt is not possible from the transmitter from
which the signal was last received, reception may take up to 14
minutes.
The receive indicator cycles from
“Unstable” through “Stable” as
shown below while reception is in
progress. How far it cycles depends
on the signal strength.
Keep the watch in a location where
reception is stable while reception is
in progress.
■ To perform signal reception manually
In the Timekeeping Mode,
hold down the D button for
about two seconds.
• The watch will beep and
reception will start. The receive
indicator cycles from “Unstable”
through “Stable” as shown
below while reception is in
progress. How far it cycles
depends on the signal strength.
■ To view the last reception date and time
Indicator
In the Timekeeping Mode, press the D button.
Module 4313
• This displays the date and time when signal reception was last
successful, and the current time and date were last adjusted.

• Orienting the watch so it is sideways to the transmitter makes it
more difficult to receive the signal.
• Do not move the watch while it is receiving the calibration signal.
When reception fails (ERR Indicator)
In the case of an error, the watch will not adjust its current time
setting, but display “ERR” instead.
• The display will return to the normal timekeeping screen automatically
if you do not perform any operation for about one or two minutes.
Module 4313
• Even under optimum reception conditions, it can take about 10
seconds for reception to stabilize.
• Use the receive indicator to check reception status and to
determine the best location for signal reception.
• Note that weather, the time of day, surroundings, and other
factors can all affect reception.

Troubleshooting
1. The watch cannot receive the time calibration signal.
• Is the signal being transmitted?
Though the time data of the Japanese calibration signal (Call
Sign: JJY) is maintained by the Japan Standard Time Group of
the National Institute of Information and Communications
Technology (NICT), it may be interrupted sometimes for periodic
maintenance work, or because of lightning or other problems.
• Are you within the reception range of a transmitter?
See “Reception Ranges” for information about areas where the
watch can receive the signal.
• Is there something in the immediate area that may be interfering
with reception?
Even if you are within the reception range of a transmitter, objects
between you and the transmitter or electrical noise can interfere
with reception. Avoid such areas during signal reception. See
“Location”.
• Do you have the correct Home City code selected?
Remember that auto receive is not performed unless one of the
following is selected as the Home City: TYO (Tokyo), SEL (Seoul),
HKG (Hong Kong), YVR (Vancouver), LAX (Los Angeles), YEA
(Edmonton), DEN (Denver), MEX (Mexico), YWG (Winnipeg), CHI
(Chicago), MIA (Miami), YTO (Toronto), NYC (New York), YHZ
(Halifax), or YYT (St. John’s). Correctly select your Home City
using the procedure under “Configuring Home Time Settings”.
• Is auto receive turned off?
Use the procedure under “Configuring Auto Receive Settings” to
turn on auto receive.
• Is the watch in any mode other than the Timekeeping Mode or
World Time Mode during the auto receive times (midnight, 1:00
a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m.)?
Auto receive is performed only when the watch is in the
Timekeeping Mode or World Time Mode. It is not performed if the
watch is in any other mode.
• Is a timer operation in progress?
Calibration signal reception is disabled while a timer operation is
in progress. Because of this, you should avoid performing timer
operations during the timeframes that signal reception is
performed, or perform manual receive after your timer operation is
complete.
2. Time calibration signal reception is successful, but the
hourly time signal and current time are off slightly.
• After the watch receives the time calibration signal, it performs an
internal decoding process before updating its time setting.
Because of this, the time setting may be off slightly (within one
second).
3. Time calibration signal reception is successful, but the
current time is one hour fast.
• Do you have summer time (DST) turned on? Use the procedure
under “Configuring Home Time Settings” to select either AUTO or
OFF for the summer time setting.
Calibration Signal Reception
Precautions
• Auto receive can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• Signal reception is not possible while a timer operation is in
progress.
• Receipt of a calibration signal causes the digital time to be
adjusted first, followed by adjustment of the analog time. In order
to ensure correct correction of the analog time, be sure to match
the analog time with the digital time before performing a signal
receive operation.
• Operating any button while auto receive is in progress will cause
the watch to beep and then exit the receive operation.
• Make sure you are within the range of the calibration signal
transmitter before performing the reception operation. Remember
that geographic contours, nearby buildings, the season, the time
of day, can even make reception impossible even when you are
within range of the transmitter.
• Proper reception may be impossible if there is something blocking
the signal. If reception is unsuccessful, try again.
• This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and
the United States only. Note that you will need to make your own
adjustments when using this watch outside of Japan or the United
States, or in any area that is outside the range of one of the
receivable time calibration signal transmitters.
• When the watch is unable to adjust its time signal using the
calibration signal for some reason, timekeeping accuracy is within
±15 seconds per month.
• Strong electrostatic charge can cause timekeeping error.
• Signal reception is cancelled if an alert operation starts while it is
being performed.
• The watch’s calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.
4. Time calibration signal reception is successful, but the
current time setting is wrong.
• Is TYO (Tokyo) or HKG (Hong Kong) selected for your Home
City? Correctly select your Home City using the procedure under
“Configuring Home Time Settings”.
8. How can I perform manual receive?
• Hold down the lower right D button for about two seconds. The
watch will beep to indicate that manual receive has started. Place
it near a window, with 12 o’clock facing in the general direction of
the transmitter.
5. The digital time and analog time are different.
• Normally, the received time calibration data is used to adjust the
digital display time, and then the analog hands are adjusted to
match the digital time. If the hands are misaligned for some
reason, they will not indicate the correct time. If this happens, use
the procedure under “Setting the Analog Time Manually” to adjust
the analog time.
9. How can I view the last reception date and time?
• In the Timekeeping Mode, press the lower right D button. This
will display the date and time that the time calibration signal was
last received successfully. To return to the Timekeeping Mode,
press the D button again.
6. Can you configure auto receive settings?
• Remember that auto receive is not performed unless one of the
following is selected as the Home City: TYO (Tokyo), SEL (Seoul),
HKG (Hong Kong), YVR (Vancouver), LAX (Los Angeles), YEA
(Edmonton), DEN (Denver), MEX (Mexico), YWG (Winnipeg), CHI
(Chicago), MIA (Miami), YTO (Toronto), NYC (New York), YHZ
(Halifax), or YYT (St. John’s). Correctly select your Home City
using the procedure under “Configuring Home Time Settings”.
7. What time is auto receive performed?
• Auto receive is performed in the middle of the night, when
reception conditions are best. Before going to bed at night, place
the watch near a window, with 12 o’clock facing in the general
direction of the transmitter.
If you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup
of the watch.
