TIMEKEEPING
This watch automatically adjusts its time setting in accordance with the time
calibration signal (Call Sign: WWVB) transmitted from the National Institute of
Standard and Technology (NIST) in Fort Collins, Colorado. You can also perform a
manual procedure to set the time and date, when necessary.
Important!
• Before using the watch after purchasing it, use the procedure under “Selecting Your
Time Zone City Code” to specify your city code, and then use the procedure under
“To trigger a calibration signal receive operation manually”.
• The Fort Collins time calibration signal includes both standard time and Daylight
Saving Time data. This means the watch can automatically adjusts for DST, even if
you do not specify it manually. See “Daylight Saving Time Setting” for more
information.
Setting the Time and Date
There are three different methods you can use to set the watch’s time and date.
• Auto receive of the time calibration signal
• Manual receive of the time calibration signal
• Manual setting without using the time calibration signal
No matter which method you use, you must specify your time zone city code first (see
below).
Selecting Your Time Zone City Code
Use one of the procedures below to specify your current time zone. If you move to a
different time zone either inside or outside of the Continental United States, simply
change the time zone setting and the watch adjusts its current time and date settings
accordingly.
• To select a time zone within the Continental United States, use the procedure under
“To select your time zone city code”.
• To select another time zone, use the procedure under “To select a time zone outside
the Continental United States”.
Important!
• Make sure you set the correct time zone city code for the time zone where you are
located. The wrong time zone city will cause the watch to display the wrong time.
• The time zone city code (LAX, DEN, CHI, NYC, etc.) is not shown on the
Timekeeping screen. See “To view the current time zone city code”.
To select your time zone city code
In the Timekeeping Mode, use the key operations shown in the table below to select
the indicated city code. Hold down this key until the watch beeps (about two seconds).
• Selecting a city code causes the year, month, day, hour, minutes, and DST settings
to change accordingly.

About the Receive Indicator
The receive indicator shows the strength of the calibration signal being received. For
best reception, be sure to keep the watch in a location where signal strength is
strongest.
Recieve indicator
Weak
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receive indicator to indicate signal strength.
• Use the receive indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
• The receive indicator remains on the display in all modes following reception of the
time calibration signal and calibration of the watch’s time setting. The receive
indicator does not appear if signal reception was unsuccessful or after manual
adjustment of the current time setting.
To trigger a calibration signal receive operation manually

Current time
• Time calibration signal reception takes from four to 11 minutes. Take care that you
do not move the watch during this time.
• To interrupt a receive operation and return to the Timekeeping screen, press A.
• When a receive operation is successful, the receive date and time change, and
the receive indicator appears on the Last Signal screen.
Note
• If the receive operation is unsuccessful, the message “ERR” appears on the Last
Signal screen for about one or two minutes. After that, the watch returns to the
Timekeeping screen.
Last Signal Screen
The Last Signal Screen appears after the watch attempts a calibration receive
operation. The Last Signal screen shows the date and time of the last receive
operation if it was successful, or an error message if the receive operation failed. You
can also display the Last Signal screen at any time using the button operation
described below.

About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the Timekeeping Mode reaches a calibration time (0:00 AM,
2:00 AM, and 4:00 AM) each day.
Note
• The Auto Receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if the calibration time is reached while you are making settings (while
settings are flashing on the display), while an alarm is sounding or while you are
performing a key operation.
• Auto receive is performed at 0:00 AM, 2:00 AM, and 4:00 AM, 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.
• The receive indicator (
time reception attempts were successful. The receive indicator disappears from the
display when the Timekeeping Mode reaches midnight or when you perform a
manual receive operation.
• When auto receive is turned on, the watch receives the calibration signal for four to
11 minutes each day when the Timekeeping Mode time reaches 0:00 AM, 2:00 AM,
and 4:00 AM. Do not operate any of the watch’s buttons within 15 minutes prior to or
following the calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the Timekeeping
Mode time. The receive operation will be performed whenever the Timekeeping
Mode time is 0:00 AM, 2:00 AM, and 4:00 AM, regardless of whether or not the
displayed time is actually the correct time.
• When two or three receptions are successful, 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.

Daylight Saving Time.
Daylight Saving Time Setting
The time calibration signal sent from Fort Collins includes Standard Time and Daylight
Saving Time information. Selecting DST AUTO for the DST setting after you select the
city code for your current time zone, you do not need to make any adjustments to
switch between Standard Time and Daylight Saving Time while you are in a U.S. area
where Daylight Saving Time is followed. The initial factory default setting for the DST
setting is DST AUTO .
• Make sure you change the DST setting to DST OFF when you are in a U.S. area
that does not follow DST.
• You need to set the DST setting whenever the time zone of the city code you have
selected is outside the Continental United States.

Data and Setting Scrolling
The (REV) and (FWD) keys are used in various modes and setting
screens to scroll through data on the display. In most cases, holding down these keys
during a scroll operation scrolls through the data at high speed.
Initial Screens
When you enter the Telememo or World Time Mode, the data you were viewing when
you last exited the mode appears first.
Timekeeping
• Pressing while setting the current time in the Timekeeping Mode resets the
second’s count to zero. Pressing
59 resets the seconds to 00 and adds 1 to the minutes. In the range of 00 to 29, the
minute’s count is unchanged.
• The day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
• The year can be set in the range of 2000 to 2099. Going past December 31, 2099
reverts to January 1, 2000.
• The watch’s built-in full automatic calendar automatically 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.
12-hour/24-hour Timekeeping
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in the World Time and Alarm Modes.
• With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for
times in the range of noon to 11:59 pm. The A (AM) indicator is shown from midnight
to 11:59 am.
• With the 24-hour format, times are indicated in the range of 0:00 to 23:59, without
any indicator.
World Time Mode
• The current times in all World Time Mode cities are calculated in accordance with
the Greenwich Mean Time (GMT) differential for each city, based on the current
Time Zone City time setting in the Timekeeping Mode.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
• The second’s count of the World Time is synchronized with the second’s count of the
Timekeeping Mode.
Time Calibration Signal Reception Precautions
1,200 miles
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2039. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2040.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• The daily alarm and hourly time signal do not operate during signal reception.
• Even when the watch is within the reception range, 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.
• This watch receives the time calibration signal transmitted from Fort Collins,
Colorado. This means that reception is best when the antenna built into the 12
o’clock edge of the watch is facing towards Fort Collins. Note, however, that moving
the watch while the time calibration signal receive operation is taking place will make
stable reception impossible.
• Think of the watch as acting like a TV or radio when it is receiving the calibration
signal. When receiving indoors, move to a location as near as possible to a window.
Proper signal reception can be difficult or even impossible under the conditions
listed below.
Near TVs, refrigerators, computers, or other household appliances
Far away from broadcasting stations among ferro-concrete structures or near
mountains
Underground, in tunnels or in ferro-concrete buildings
Near high-tension wires, neon signs, or radio stations with interfering frequencies
Near railroads, highways or airports
In trains or cars
• Radio interference can make signal reception impossible.
• Strong electrostatic charge can result in the wrong time being set.
• 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.
2,000 miles
Fort Collins
• This watch receives the time calibration signal (Call
Sign: WWVB) transmitted from Fort Collins, Colorado.
Signal reception is possible within a radius of about
2,000 miles (3,000 kilometers) from the Fort Collins
transmitter.
• The current time setting in accordance with the time
calibration signal takes priority over any time settings
you make.
• The Fort Collins time calibration signal includes DST
data.

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 (except for the Stopwatch Mode),
press D to illuminate the display for about two seconds.
• The electro-luminescent panel that provides illumination loses power after very long
use.
• 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 battery life.
About the Battery
The indicator BATT flashes on the display whenever 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 alarm operations
• Failure of time calibration signal reception
• Inability to input or recall Telememo data
If battery power goes low while you are inputting Telememo 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 FOLLOWING INFORMATION TO THE PERSON
REPLACING THE BATTERY.
RECOVER Message
Certain functions consume large amounts of battery power, and using them too much
can cause a sudden momentary drop in battery power. The watch monitors how much
you use these high consumption functions, and displays the RECOVER message
whenever it determines you are using them too much.
• Backlight and alarm operation, time calibration signal reception, and all Telememo
operations are disabled while RECOVER is on the display.
• The following are the trigger values for functions that are monitored for battery usage.
High Power Consumption FunctionTrigger Value
• RECOVER appears whenever any of the above operations is performed individually
in succession for the number of times indicated by its trigger value. RECOVER also
appears when a combination of functions reaches a trigger value. Examples: 50
backlight operations + 50 signal receive operations, 25 backlight operations
+ 25 signal receive operations, + 800 button input tone operations, etc.
• RECOVER disappears from the display after the battery recovers its normal power
level after it has a chance to “rest.”
Attention dealer or CASIO distributor
Be sure to use the following procedure when replacing the battery.
1. Open and remove the back cover.
• Opening the back cover causes the message OPEN to appear on the display.
• If CLOSE appears on the display when you open the back cover, replace the
back cover. Wait for a few minutes and try again.
2. Remove the battery holder.
3. Remove the old battery and load a new one.
4. Replace the battery holder.
5. Touch the AC contact and the battery [+] side with metallic tweezers.
• The AC (all clear) operation
6. Close the back cover.
7. Press any button besides A. This causes the watch to start an internal data check,
which is indicated by CHECK appearing on the display. The Timekeeping Mode
display appears after the internal check is complete.
• The internal check takes up to five or six minutes. All watch buttons are disabled
during that time.
