Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch automatically picks up the time calibration signal three
times a day at 2:00 AM, 4:00 AM, and 5:00 AM. For more information, see “About Auto
Receive.”
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive.”

Radio-controlled Timekeeping
• Under good reception conditions, signal reception is possible within a radius of
about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.
• At distances further than about 600 miles (1,000 kilometers) from the Fort Collins
transmitter, the signal may become weak and reception may be impossible under
certain conditions.
• At distances further than about 500 kilometers from the Fukushima and Fukuoka/
Saga transmitter, the signal may become weak and reception may be impossible
under certain conditions.
This watch is designed to pick up a time calibration signal and updates its time setting
accordingly. The time calibration signal includes both Standard Time and Daylight
Saving Time (summer time) data.
• When within range of the applicable transmitter, this watch can receive either
Continental U.S. or Japanese time calibration signals.
Current Time Setting
• See the information under “Signal Receive Troubleshooting” if you experience
problems with time calibration signal reception.
This watch automatically adjusts its time setting in accordance with a time calibration
signal.You can also perform a manual procedure to set the time and date, when
necessary.
About Auto Receive
• The first thing you should do after purchasing this watch is to set your Home City,
which is the city where you will normally use the watch. For more information, see
“To set your Home City” below.
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM,
and 5:00 AM each day (calibration times).
• See “Timekeeping” for information about manual settings.
Note
To set your Home City
• The watch performs auto receive only if Mode Menu screen is on the display, or if
the watch is in the Timekeeping Mode, or World Time Mode when one of the
calibration times is reached. Auto receive 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 six
minutes everyday when the Timekeeping Mode reaches each of the three calibration
times. Do not perform any button operation within six minutes before or after any of the
three calibration times. Doing so can interfere with correct calibration.
1. Enter the Timekeeping Mode.
2. Hold down A until the seconds start to flash, which
indicates the setting screen.
3. Press C twice so the current city code is flashing.
4. Use D (east) and B (west) to scroll through the city
codes until the one you want to use as your Home City

• Though this watch is designed to receive both time data (hour, minutes, seconds)
Daylight Saving Time (DST)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
• When all three auto receptions are successful (2:00 AM, 4:00 AM, and 5:00 AM), 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.
• Normally, the signal reception date shown by the Last Signal screen is date data that
is included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows date as kept in the Timekeeping Mode at the
time of signal reception.
The time calibration signal transmitted from Fort Collins, Colorado includes both
Standard Time and DST data. When the auto DST setting is turned on, the watch
switches between Standard Time and DST (summer time) automatically in
accordance with the Fort Collins signal.
• The time calibration signals transmitted from the Fukushima and Fukuoka/Saga do
not include summer time data.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±15 seconds a month at normal temperature.
• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code and DST
(summer time) settings, and auto receive setting. The following are the initial factory
defaults for these settings.
• The auto DST setting can be turned on only while HNL, ANC, LAX, DEN,
CHI, NYC, TYO, SEL, or HKGis selected as the Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.

and C at the same time.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
Inputting Text
The following describes how to input text in the Recall Mode, e-DATA MEMORY and
Alarm Modes.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
To input characters
1. When the cursor is on the display, press D to cycle
through the available letters, numbers and symbols, in
the sequence shown below.
Cursor
* The letters “UTC” stands for “Universal Time Coordinated,” which is the world-wide
scientific standard of timekeeping. It is based upon carefully maintained atomic
(cesium) clocks that keep time accurately to within microseconds. Leap seconds
are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation. The reference point for UTC is Greenwich, England.

12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all modes.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and the A (AM) indicator appears for times in the range
of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without

press C to move the cursor to the right.
3. Repeat steps 1 and 2 to input the rest of the characters you want.
• See the “Character List” for information about the characters you can input.
Auto Return Features
• If you leave the watch without performing any operation in the Signal Receive,
Recall, e-DATA MEMORY, or Alarm Mode for two or three minutes, it automatically
changes to the Mode Menu screen.
• If you leave a screen with flashing digits or a cursor on the display for two or three
minutes without performing any operation, the watch automatically exits the setting
screen.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode, press L to illuminate the display for
about one second.
• The electro-luminescent panel that provides illumination loses power after very long
Scrolling
use.
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the life of the battery.
Initial Screens
When you enter the e-DATA MEMORY, World Time, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.
Time Calibration Signal Reception Precautions
Battery
• Signal reception is terminated if any alarm starts to sound while reception is being
The indicator BATT flashes on the display any time
battery power is below a certain level. Low battery power
can cause the following conditions to occur.
• Dim, difficult-to-read display characters
• Failure of the backlight and beeper tone operations
performed.
• Strong electrostatic charge can result in the wrong time being set.
• Even when the watch is within the reception range of the transmitter, signal
reception is 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.
• The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.

If battery power goes low while you are inputting Time Memo, e-DATA MEMORY, or
alarm text data, the data you are inputting may not be saved in memory. Normal watch
operation will return after the BATT indicator disappears. If it does not disappear, have
the battery replaced.
Always leave battery replacement up to the dealer where you bought the watch or
to an authorized CASIO distributor. Be sure to show the “Attention dealer or CASIO
distributor” information to the person replacing the battery.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
