Operation Guide 5088

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.

This User’s Guide uses numbers shown above to identify watch hands and indicators.

Things to check before using the watch

1. Hold down C for about two seconds to enter the Timekeeping Mode, and

then observe the movement of the x

Is the x Second Hand moving smoothly in one-second intervals?

Is the x Second Hand moving at two-second intervals or is it stopped completely?

Power is low. Charge the watch by placing it in a location where it is exposed to light. For details, see “Charging the Watch”.

YES

2. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To conﬁ gure Home City settings” to conﬁ gure your Home City and daylight saving time settings.

Important!

Proper time calibration signal reception and World Time settings depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you conﬁ gure these settings correctly.

3. Set the current time.

 To set the time using a time calibration signal See “To get ready for a receive operation”.  To set the time manually See “Conﬁ guring Current Time and Date Settings Manually”.

The watch is now ready for use.

For details about the watch’s radio controlled timekeeping feature, see “Radio  Controlled Atomic Timekeeping”.

Charging the Watch

The face of the watch is a solar cell 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

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.

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 if its face is blocked by your sleeve even only partially.

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 sufﬁ ciently 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.

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.

You can get an idea of the watch’s power level by observing the movement of the x Timekeeping Mode.

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” 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:

LON, PAR, ATH Anthorn (England), Mainﬂ ingen (Germany)

HKG Shangqiu City (China)

TYO Fukushima (Japan), Fukuoka/Saga (Japan)

HNL, ANC, LAX, DEN, CHI, NYC Fort Collins, Colorado (United States)

Important!

The areas covered by  HNL and ANC are quite far from the calibration signal transmitters, so certain conditions may cause reception problems. When  HNL or HKG 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” for information about how to do this.

The watch can receive the signal from the transmitter located here:

To get ready for a receive operation

Conﬁ rm that the watch is in the Timekeeping Mode. If it isn’t, hold down 1. C for about two seconds to enter the Timekeeping Mode.

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

Signal reception may be difﬁ cult or even impossible under the conditions  described below.

Inside or among buildings

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

Auto Receive: Leave the watch over night in the location you selected in step 2.  See “Auto Receive” for details. Manual Receive: Perform the operation under “To perform manual receive”. 

Auto Receive

With Auto Receive, the watch performs the receive operation each day  automatically up to six times (up to ﬁ ve 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 or World Time Mode. The receive operation is not performed if a calibration time is reached while you are conﬁ guring settings.

Adjusting the 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.

Hand home position adjustment is not required if the time and day settings are  correct. You also can use auto correction of the hand home positions to correct the home  positions of the z

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.

Troubleshooting

Hand Movement and Position

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

Refer to “To select a mode”. To return directly to the Timekeeping Mode from any other mode, hold down C for about two seconds.

Second Hand is moving at two-second intervals.

■ The x

■ 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 x normally, at one-second intervals.

■ The hands of the watch suddenly start moving at high speed, even when I do not perform any operation.

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.

The watch is recovering from a sleep state.  The time setting is being adjusted following a successful auto time calibration  signal receive operation. The watch is returning to the Timekeeping Mode automatically from the Alarm  Mode.

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

The watch may be in the power recovery mode. 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.

■ 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 conﬁ gure Home City settings”. 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” to change the STD/DST setting.

■ 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.

World Time Mode

■ The World Time indicated by the b 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.

■ The World Time indicated by the b Mode is off.

Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary.

Charging

■ The watch does not resume operation after I expose it to light.

This can happen after the power level drops to Level 3. Continue exposing the watch to light until the x

■ The x returns to moving at two-second intervals.

The watch probably is not sufﬁ ciently charged yet. Continue keeping it exposed to light.

Possible Cause Remedy

You are wearing or moving the watch, or  performing a button operation during the signal receive operation.

The watch is in an area with poor reception  conditions.

You are in an area where signal reception is not possible for some reason.

The calibration signal is not being transmitted for some reason.

Keep the watch in an area where reception conditions are good while the signal receive operation is being performed.

See “Approximate Reception Ranges”.

■ The current time setting changes after I set it manually.

You may have the watch conﬁ gured for Auto Receive of the time calibration signal, 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.

■ The current time setting is off by one hour.

Possible Cause Remedy

Signal reception on a day for switching between STD (standard time)/DST (daylight saving time) may have failed for some reason.

Perform the operation under “To get ready for a receive operation”. The time setting will be adjusted automatically as soon as signal reception is successful.

If you are unable to receive the time calibration signal, change the STD (standard time)/DST (daylight saving time) setting manually.

■ Auto Receive is not performed or I cannot perform Manual Receive.

Possible Cause Remedy

The watch is in the Stopwatch Mode.

Your Home City setting is wrong.

There is not enough power for signal reception.

■ Signal reception is being performed successfully, but the time and/or day is wrong.

Possible Cause Remedy

Your Home City setting is wrong.

The watch may have been exposed to magnetism or strong impact, which has caused problems with proper hand and day alignment.

Auto Receive is not performed while the watch is in the Stopwatch Mode. Hold down C for about two seconds to enter the Timekeeping Mode.

Check your Home City setting and correct it, if necessary.

Expose the watch to light to charge it.

Check your Home City setting and correct it, if necessary.

Adjust the watch’s hand and day home positions.
