Using the Crown

The crown of this watch has a button part and a ring part. You can use the crown's button and ring to perform a number of different crown operations.

Locking the Crown

To lock the crown, push down its ring part as far as it will go as you rotate the ring away from you until it is relatively tight. While the crown is locked correctly, the only crown operations possible are pressing the crown button and unlocking the crown.

Important!

- Push down on the ring as you slowly rotate it. You should be able to feel it screwing securely into place.

- You should normally have the crown locked during normal daily use. Leaving the crown unlocked creates the risk of unintended operations or even damage due to impact.

E-3

- Note that rotating the ring without pushing it down as far as it will go will change the settings of the watch. When looking the crown, be sure to press down firmly on the ring as you rotate it.

Unlocking the Crown

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Whenever you are not wearing the watch, be sure to leave it in a location where it is exposed to light. ■Best charging

performance is achieved by exposing the watch to light that is as strong as possible.

When wearing the watch, makes sure that its face is not blocked from light by the sleeve of your clothing.

•The watch may enter a sleep state (page E-22) if its face is blocked by your sleeve oven only partially.

Warning!

Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

On the dashboard of a car parked in direct sunlight

Too close to an incandescent lamp

Under direct sunlight •

Important!

Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.

Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

E-16

E-17

Power Levels

You can get an idea of the watch's power level by observing the movement of the 2 Second Hand in the Timekeeping Mode.

If the 2 Second Hand is moving normally at one-second intervals, power is at Level 1.

4 If the 2 Second Hand is moving at two-second intervals, power is at Level 2, which is quite low. Expose the watch to light as soon as possible so it can charge.

Moves at two-second

intervals

E-18

Level Hand Movement Function Status
1 Normal. All functions enabled
2	2 Second Hand moves at two-second intervals6 Day changes to 1 (home position);	Baccar, time calibration signal reception, and countdown timer operation disabled
3	2 Second Hand stopped,11 Hour Hand and 12 Minute Hand stopped at 12 o'clock.	All functions disabled

- When power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

E-19

Operation Guide 5142

CASIO®

- A short while after exposing the watch to light after its battery charge has run down will cause the 23 Second Hand to move counterclockwise until it stops at second 57 on the face. This indicates that charging has started. See page E-21 for information about required charging times.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to overuse of the alarm tone over a short period. Note that all operations are disabled while the watch is in the power recovery mode.

The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

Charging Times

Exposure Level (Brightness)	Daily Operation *1	Level Change *2
		Level 3	Level 2	Level 1
		→		→
Outdoor sunlight (50,000 lux)	8 minutes	2 hours		23 hours
Window sunlight (10,000 lux)	30 minutes	6 hours		87 hours
Window sunlight on cloudy day (5,000 lux)	48 minutes	9 hours		140 hours
Indoor fluorescent lighting (500 lux)	8 hours	94 hours

* 1 Approximate exposure each day to generate power for normal daily operation.

* 2 Approximate exposure to take power up one level.

•The above times are for reference only. Actual times depend on lighting conditions.

- For details about the operating time and daily operating conditions, see the "Power Supply" section of the Specific cations (page E-108).

E·21

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

There actually are two sleep state levels: "second hand sleep" and "function sleep".

Elapsed Time In Dark Operation
60 to 70 minutes (second hand sleep)	Second Hand only stopped, all other functions enabled
6 or 7 days (function sleep)	All functions, including analog timekeeping, disabledWorld Time Mode time stopped at the point the Timekeeping Mode time reached 0.00

- The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

The watch will not enter a sleep state while it is in the Stopwatch Split Mode, Stopwatch Lap Mode, or Countdown Timer Mode.

E-22

To recover from the sleep state

Move the watch to a well-lit area, press any button, or perform a crown operation (push in, pull out, rotate).

E-23

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See "Confi guring Current Time and Date Settings Manually" (page E-55) for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

If your Home City Code setting is this:	The watch can receive the signal from the transmitter located here:
LON (LONDON), PAR (PARIS), ATH (ATHENS)	Anthom (England), Mainflingen (Germany)
HKG (HONG KONG) Shangqiu City (China)
TYO (TOKYO)	Fukushima (Japan), Fukuoka/Saga (Japan)
FNI (HONOLULU), ANC (ANCHORAGE), LAX (LOS ANGELES), DEN (DENVER), CHI (CHICAGO), NYC (NEW YORK)	Fort Collins, Colorado (United States)

E-24

E-25

Important!

• The areas covered by HNL (HONOLULU) and ANC (ANCHORAGE) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
• WhenHNL (HONOLULU) or HKG (HONG KONG) is selected as the Home City, only the time and date are adjusted according to the time calibration signal. You need to switch manually between standard time and daylight saving time (DST) if required. See "To toggle the Home City time between standard time and daylight saving time" (page E 51) for information about how to do this.

Operation Guide 5142

CASIO®

To get ready for a receive operation

1. Confirm that the watch is in the Timekeeping Mode. If it isn't, push in and hold the crown for at least two seconds to enter the Timekeeping Mode.

2. Place the watch in a location where signal reception is good.

12 o'clock or

Position the watch as shown in the nearby illustration, with 12 o'clock pointed towards a window. Make sure there are no metal objects nearby.

- Signal reception normally is better at night.

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.

- Signal reception may be difficult or even impossible under the conditions described below.

Inside or among buildings

Inside a vehicle

Near household appliances offi ca equipment, or a mobile phone

Near a construction site, airport, or other sources of electrical noise

Near high-tension power lines

Among or behind mountains

E-30

E-31

3. What you should do next depends on whether you are using Auto Receive or Manual Receive.

*Auto Receive: Leave the watch over night in the location you selected in step 2. See "Auto Receive" on page E-32 for details.

- Manual Receive: Perform the operation under "To perform manual receive" on page E-33.

Auto Receive

- 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.

- When a calibration time is reached, the watch will perform the receive operation only if it is in the Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you are continuing settings.

E-32

To perform manual receive

1. In the Timekeeping Mode (page E-44), keep Ⓑ depressed (for about two seconds) as the 2 Second Hand goes through the following sequence.

- Moves to Y (or YES for some models) or N (NO) to indicate the last signal reception result, then to R (READY).

1. The 2 Second Hand indicates the operations the watch is currently performing.
   

When the [2] Second Hand is pointed here:	It means this:
R (READY)	Welch is selling up for reception.
W (WORK)	Reception is in progress.
Y (YES)	Reception was completed successfully.
N (NC)	Reception failed for some reason.

- If signal reception is unstable, the ② Second Hand may move between W (WORK) and R (READY). - When the receive operation is successful, the watch adjusts the time setting accordingly, and then resumes normal timekeeping. It does not adjust the setting if the operation failed.

E-34

E-33

Note

To interrupt a receive operation and return to the Timekeeping Mode, press any button.

To check the result of the latest receive operation

In the Timekeeping Mode, press ⑧. ④The② Second Hand will move to Y (YES) for about one second if the latest receive operation was successful, or N (NO) if it was not. After that, regular timekeeping will resume. ⑤You can return to the Timekeeping Mode manually by pressing ⑥ while the ② Second Hand is pointing to Y (YES) or N (NO).

Note

The 2 Second Hand will indicate N (NO) if you have adjusted the time or date setting manually since the latest receive operation.

E-35

Radio-controlled Atomic Timekeeping Precautions

• Strong electrostatic charge can result in the wrong lime selling.

- Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.

•The watch is designed to update the date and day of the week automatically for the period January 1, 2000 to December 31, 2009. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.

- If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in "Specili cations" (page E-105).

- The receive operation is disabled under any of the following conditions. - White power is at Level 2 or lower (page E-18)

- While the watch is in the power recovery mode (page E-20)

- While the watch is in the function sleep state (power saving, page E-22)

- While a countdown time operation is in progress (page E-73)

- A receive operation is cancelled if an alarm sounds while it is being performed.

Mode Disk Pointers

The 4 Mode Disk uses three different pointers to indicate a variety of different information: a mode pointer, a split pointer, and a lap pointer.

Mode Pointer

The mode pointer is in a fixed position. Whenever you enter a mode, the Mode Disk will rotate until the current mode indicator (AL, TR, ST, TM, or WT) is aligned with the mode pointer. The mode pointer is also used for indication of standard time (STD or STD-AT) and daylight saving time (DST or DST-AT).

Split Pointer

The split pointer is marked on the Mode Disk. Whenever you enter the Stopwatch Split Mode (page E-63), it indicates the current status of the stopwatch operation. While a normal stopwatch elapsed time measurement operation is in progress, the split pointer will point to RUN. When a split time is indicated by the hands (which are temporarily stopped), the split pointer will point to SPL. Stopping the elapsed time measurement operation will cause the split pointer to move to STP (stop).

Lap Pointer

The lap pointer is marked on the 4 Mode Disk. Whenever you press to perform lap time measurement in the Stopwatch Mode, the 4 Mode Disk will rotate so the lap pointer points at the current lap number (1 through 5). If the current lap number is greater than 5, the lap pointer will point at ▶.

Selecting a Mode

With this watch, everything starts from the Timekeeping Mode.

To determine the watch's current mode

Check what the mode pointer is indicating on the 4 Mode Disk as shown under "To select a mode" (page E-41).

To return to the Timekeeping Mode from any other mode

Press and hold the crown button (without unlocking the crown) for at least two seconds.

To select a mode

Each press of the crown button cycles through the modes in the sequence shown below. The 4 Mode Disk rotates so the selected mode is indicated by the mode pointer.

Movement of the 4 Mode Disk may cause the watch hands to move slightly. This is due to fine adjustment of hand positions and does not indicate malfunction.

Configuring Home City Settings

There are two Home City settings: actually selecting the Home City and selecting either standard time or daylight saving time (DST).

To configure Home City settings

Note

- This watch does not have a city code that corresponds to Newfoundland.

Press and hold the crown button (without unlocking 1. the crown) for at least two seconds.

•This will enter the Timekeeping Mode (page E-42).

Unlock the crown and then pull it out.2.

•This will cause the 2 Second Hand to move to the
city code of the currently selected Home City
- This indicates the city code setting mode.

E-45

E-44

If you do not perform any operation with the crown - for about three minutes after pulling it out, crown operations will become disabled and the watch hands will no longer move when you rotate the crown. If this happens, push the crown back in and then pull it out again;
- For details about city codes, see the "City Code Table" at the back of this manual.

Rotate the crown to move the ② Second Hand to the city code you want to select as your Home City.

Each time you change to a different city code, the 1 Hour Hand, 3 Minute Hand and 6 Day move to the current time and date for that city code. Also, the 4 Mode Disk rotates until the mode pointer is pointing at STD. STD-AT, DST, or DST-AT (see step 4 of this procedure below).

Press 4. Ⓐ to toggle the currently selected city code between standard time and daylight saving time.

In the city code setting mode, the4 Mode Disk indicates STD (standard time) or DST (daylight saving time).

• No AT batting (STD-AT or DST-AT) will be indicated only if the currently selected city code is one that supports time calibration signal reception
• WhileAT is selected, the watch will switch between STD and DST automatically in accordance with time calibration signal data.

- The initial default setting is STD-AT when any one of the following city codes is selected as the Home City code: LON (LONDON), PAR (PARIS), ATH (ATHENS), NYC (NEW YORK), CHI (CHICAGO), DEN (DENVER), LAX (LOS ANGELES), ANC (ANCHORAGE), or TYO (TOKYO).

For details about the Daylight Saving Time setting, see "Daylight Saving Time (DST)" (page E-48).

E-46

E-47

After the settings are the way you want, push the crown back in to return to the 5. Timekeeping Mode. Next, lock the crown.

- Rotating the ring without pushing it down as far as it will go will change the settings of the watch. When locking the crown, be sure to press down firmly on the ring as you rotate it.

Daylight Saving Time (DST)

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.
The time calibration signals transmitted from Mainfl ingen (Germany), Anthom (England), or Fort Collins (the United States) include both Standard Time and DST data.
- Note that an AT setting (STD-AT or DST-AT) will be indicated only if the currently selected only code is one that supports time calibration signal reception. While AT is selected, the watch will switch between STD and DST automatically in accordance with time calibration signal data.

STD-AT	When a transmitted daylight saving time signal is received, switches to daylight saving time (DST-AT) automatically.
DST-AT	When a transmitted standard time signal is received, switches to standard time (STD-AT) automatically.
STD	Even if a transmitted daylight saving time signal is received, standard time (STD) setting does not change.
DST	Even if a transmitted standard time signal is received, daylight saving time (DST) setting is not changed.

- The initial default setting is STD-AT when any one of the following city codes is selected as the Home City code: LON (LONDON), PAR (PARIS), ATH (ATHENS), NYC (NEW YORK), CHI (CHICAGO), DEN (DENVER), LAX (LOS ANGELES), ANC (ANCHORAGE), or TYO (TOKYO).

CASIO®

- Note that you cannot switch between STD (standard lime) and DST (daylight saying lime) while UTC* is selected as your Home City.

* Coordinated Universal Time, the world-wide scientific standard of timekeeping. The reference point for UTC is Greenwich, England. • If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually (page E-53).

STD/DST Switching

STD/DST switching can be performed either automatically or manually, depending on time calibration signal reception conditions in your area, the use of daylight saving time in your area, etc.

- To configure the watch to switch between STD and DST automatically in accordance with a time calibration signal, see "To toggle the Home City time between standard time and daylight saving time" (page E-51). - To override time calibration data and use a fixed STD/DST setting, see "To manually override a time calibration standard time/daylight saving time setting" (page E-53).

To toggle the Home City time between standard time and daylight saving time

Perform steps 1 through 3 under "To configure Home 1. City settings" on page E-45.

•Each time you select a city code, the 1 Hour Hand and 3 Minute Hand move to the current time for that city code.

Press 2. Ⓐ to toggle the time for the currently selected city code between standard time and daylight saving time.

- The mode pointer will point to either STD (standard time) or DST (daylight saving time) on the 4 Mode Disk, which indicates the current daylight saving time setting.

Troubleshooting

Hand Movement and Position

■ I lost track of what mode the watch is in.

Refer to "To select a mode" (page E-41). To return directly to the Timekeeping Mode from any other mode, press and hold the crown button (without unlocking the crown) for at least two seconds.

■ When pressing the crown button to enter the Stopwatch Split Mode from the Timekeeping Mode, the crown needs to be held down longer than when switching to another mode.

The watch is designed this way in order to ensure that the Timekeeping Mode is not exited unintentionally due to accidental pressing of the crown button. When entering the Stopwatch Split Mode from the Timekeeping Mode, press the crown button and hold it down until the mode changes.

■ Hands suddenly stop moving. Button operation also is disabled.

The watch may be in the power recovery mode (page E-20). 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 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-45).

■ 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-45).

- The watch's STD-AT (standard time)/DST-AT (daylight saving time) selling can be configured for auto switching in accordance with a time calibration signal. You also can manually override the STD/DST setting configured by the calibration signal. If you use manual override to select a setting, timekeeping will be off by one hour following an STD/DST switching data in your area, even if the watch is receiving a time calibration signal. Select the correct STD (standard time)/DST (daylight saving time) setting to suit your current location (page E-48). 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-51) to change the STD/DST selling.

■ 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-88).

Crown Operations

The watch seems to change modes on its own.

The watch will change modes whenever you press the button part of the crown. You can disable mode switching when the crown button is pressed, if you want. See "To disable crown button mode switching" (page E-8).

The watch will not change modes.

Crown button mode switching may be disabled. Re-enable crown button mode switching. See iTo is enable crown button mode switching" (page 5.2)

Nothing happens when I rotate the crown while it is pulled out.

You did not perform any operation for more than three minutes while the crown was pulled out, causing operation to become disabled automatically. Push the crown in and pull it back out again to re-enable operation. See "Using the Crown" (page E-3).

E-97

Nothing happens when I press the crown button.

To prevent unintentional operation, the button press operation of the crown is disabled automatically for about eight seconds after you push the crown back in. It will become re-enabled after about eight seconds. See "Pushing the Crown In" (page E-7).

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-18). Continue exposing the watch to light until the 2 Second Hand starts moving normally (at one-second intervals).

The ■ Second 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.
