ENGLISH  
Congratulations upon your selection of this CASIO watch.  
This watch does not have a city code that corresponds to the UTC offset of –3.5  
hours. Because of this, the radio-controlled atomic timekeeping function will not  
display the correct time for Newfoundland, Canada.  
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage  
or loss suffered by you or any third party arising through the use of this product or  
its malfunction.

x Even when the watch is within range of a transmitter, signal reception may be  
impossible due to the effects of geographic contours, structures, weather, the time  
of year, the time of day, radio interference, etc. The signal becomes weaker at  
distances of approximately 500 kilometers, which means that the influence of the  
conditions listed above becomes even greater.  
x Signal reception may not be possible at the distances noted below during certain  
times of the year or day. Radio interference may also cause problems with  
reception.  
x Using this watch in a country covered by a time calibration that is different from the  
countries it supports may result in incorrect time indication due to local application  
of summer time, etc.  
To get ready for a receive operation  
1. Confirm that the watch is in the Timekeeping Mode. If it isn’t, hold down C for  
about two seconds to enter the Timekeeping Mode.  
2. Place the watch in a location where signal reception is good.  
x Position the watch as shown in the

x The receive operation takes from two to seven minutes, but in some cases it  
can take as long as 14 minutes. Take care that you do not perform any button  
operation or move the watch during this time.  
x Signal reception may be difficult or even impossible under the conditions  
described below.  
3. What you should do next depends on whether you are using Auto Receive or  
Manual Receive.  
x Auto Receive: Leave the watch over night in the location you selected in step 2.  
See “Auto Receive” on page E-25 for details.  
x Manual Receive: Perform the operation under “To perform manual receive” on  
page E-26.  
Auto Receive  
x With Auto Receive, the watch performs the receive operation each day  
automatically up to six times (up to five times for the Chinese calibration signal)  
between the hours of midnight and 5 a.m. (according to the Timekeeping Mode  
time). When any receive operation is successful, none of the other receive  
operations for that day are performed.  
x When a calibration time is reached, the watch will perform the receive operation  
only if it is in the Timekeeping Mode or World Time Mode. The receive operation is  
not performed if a calibration time is reached while you are configuring settings.

Swapping your Home City and World Time City  
6
To swap your Home City and World Time City  
1. In the World Time Mode, use D to select the World  
Time City you want.  
x In this example, you would move the xSecond Hand  
to NEW YORK (NYC) in order to select New York as  
the World Time City.  
x Wait until the nRight Dial Hands complete their  
move to the time in the currently selected World Time  
City. You will not be able to perform step 2 of this  
procedure until the hands stop moving.  
You can use the procedure below to swap your Home City and World Time City. This  
capability can come in handy when you frequently travel between two locations in  
different time zones.  
The following example shows what happens when the  
Home City and World Time City are swapped while the  
Home City originally is TOKYO (TYO) and the World Time  
City is NEW YORK (NYC).

2. Hold down B for about three seconds until the watch beeps.  
x This will make the World Time City (NEW YORK (NYC) in this example) your new  
Home City. At the same time, it will change the Home City you had selected prior  
to step 2 (TOKYO (TYO) in this example), to your World Time City.  
x After swapping the Home City and World Time City, the watch will stay in the  
World Time Mode. The xSecond Hand will point to your new World Time City  
(TOKYO (TYO) in this example).

Using the Alarm  
When the alarm is turned on, an alarm will sound for about 10 seconds each day  
when the time in the Timekeeping Mode reaches the preset alarm time. This is true  
even if the watch is not in the Timekeeping Mode.  
Note  
x If your current World Time City supports time calibration signal reception, making it  
your Home City enables calibration signal reception for that city.

1. Use C to move the vLeft Dial Hand to AL.  
Adjusting Home Positions Manually  
Strong magnetism or impact can cause the hands and/or date of the watch to be  
off, even if the watch is able to perform the signal receive operation. If this happens,  
perform the applicable home position adjustment procedures in this section.  
x Hand home position adjustment is not required if the time and day settings are  
correct.  
2. Use D (+) and B (–) to change the alarm time setting.  
x Each press of either button will move the nRight Dial Hands one minute.  
x Holding down D or B will start high-speed hand movement in the applicable  
direction. To stop high-speed hand movement, press any button.  
x The alarm always works based on the time kept in the Timekeeping Mode.  
x The watch will return to the Timekeeping Mode automatically if you do not  
perform any operation in the Alarm Mode for about two or three minutes.  
Note  
Any time after you enter the home position adjustment mode in step 1 of the following  
procedure, you can return to the Timekeeping Mode by pressing A. The watch also  
will return to the Timekeeping Mode automatically if you do not perform any operation  
for about two or three minutes in home position adjustment mode. In either case, any  
adjustments you made before the watch returned to the Timekeeping Mode will be  
applied.  
To turn the alarm on or off  
In the Alarm Mode, press A to toggle the alarm on and off. The xSecond Hand will  
indicate the current ON/OFF setting.

Hand Movement and Position  
I lost track of what mode the watch is in.  
Refer to “To select a mode” (page E-32). To return directly to the Timekeeping Mode  
from any other mode, hold down C for about two seconds.  
6. After confirming that the vLeft Dial Hand is in the  
correct home position, press C. This will advance to  
day home position adjustment.  
x The mDay is in the correct home position if it  
shows 1. If it doesn’t, use D (+) and B (–) to change  
the day to 1.  
The xSecond Hand is moving at two-second intervals.  
All the watch’s hands are stopped at 12 o’clock and none of the buttons work.  
Power may be low. Expose the watch to light until the xSecond Hand starts moving  
normally, at one-second intervals (page E-12).

7. Press A to return to the Timekeeping Mode.  
x The mDay moves to the current day, and then the zHour Hand and the  
cMinute Hand move to the current time. Wait until everything stops moving.  
E-62  
E-63  
The hands of the watch suddenly start moving at high speed, even when I do  
not perform any operation.  
The current time setting is off by hours.  
Your Home City setting may be wrong. Check your Home City setting and correct it, if  
necessary (page E-34).  
This could be due to any one of the following causes. In all cases, the hand movement  
does not indicate malfunction, and should stop shortly.  
x The watch is recovering from a sleep state (page E-16).  
x The time setting is being adjusted following a successful auto time calibration  
signal receive operation (page E-18).  
The current time setting is off by one hour.  
If you are using the watch in an area where time calibration signal reception is  
possible, see “To configure Home City settings” (page E-34).  
If you are using in the watch in an area where time calibration signal reception is  
not possible, you may need to change your Home City’s STD (standard time)/DST  
(daylight saving time) setting manually. Use the procedure under “To toggle the Home  
City time between standard time and daylight saving time” (page E-36) to change the  
STD/DST setting.  
x The watch is returning to the Timekeeping Mode automatically from the Alarm Mode  
(page E-58).  
Hands suddenly stop moving. Button operation also is disabled.  
The watch may be in the power recovery mode (page E-14). Do not perform any  
operation until the hands return to their normal positions (in about 15 minutes). The  
hands should return to their correct positions when normal operation returns. To help  
power recover, leave the watch in a location where it is exposed to light.  
The hands and/or day indications are off.  
This could indicate that the watch has been exposed to magnetism or strong impact,  
which has caused problems with proper hand and day alignment. Adjust the watch’s  
hand and day home position alignment (page E-59).  
E-64  
E-65  
The xSecond Hand starts to move at one-second intervals, but then suddenly  
returns to moving at two-second intervals.  
The watch probably is not sufficiently charged yet. Continue keeping it exposed to  
light.  
World Time Mode  
The World Time indicated by the nRight Dial Hands in the World Time Mode is  
one hour off from the actual time in the selected time zone.  
The STD (standard time)/DST (daylight saving time) setting of the selected World  
Time City may be wrong. Select the correct STD (standard time)/DST (daylight saving  
time) setting (page E-53).  
Time Calibration Signal  
The information in this section applies only when LONDON (LON), PARIS (PAR),  
ATHENS (ATH), HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX),  
DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC), HONG KONG (HKG), or  
TOKYO (TYO) is selected at the Home City. You need to adjust the current time  
manually when any other city is selected as the Home City.  
The World Time indicated by the nRight Dial Hands in the World Time Mode  
is off.  
Your Home City setting may be wrong. Check your Home City setting and correct it, if  
necessary (page E-34).  
Charging  
The watch does not resume operation after I expose it to light.  
This can happen after the power level drops to Level 3 (page E-12). Continue  
exposing the watch to light until the xSecond Hand starts moving normally (at one-  
second intervals).

You may have the watch configured for Auto Receive of the time calibration signal  
(page E-25), which will cause the time to be adjusted automatically according to your  
currently selected Home City. If this results in the wrong time setting, check your  
Home City setting and correct it, if necessary (page E-34).
