Current Time Mode with Radio Control

This mode is used for receiving the time signal and adjusting the watch accordingly. The signal includes information about Daylight Saving Time (DST) and Standard Time.

Your watch can receive time signals from Rugby (England) and Mainflingen (Germany).

Setting Current Time

Your watch automatically adjusts itself via the radio time signal. If you are outside the signal reception area, you can set the time manually.

• Set the city code for the time zone you use as your Local Time.
• Digital and analog time are synchronized. The analog time is automatically set whenever you adjust the digital time.

How to Set Your Watch for Your City

1. In the Current Time Mode, press and hold [Button A] until the city code on the lower display flashes, indicating entry into the setting mode.
2. Use [Button D] (East) and [Button B] (West) to select the city whose time you will use as your Local Time.
3. Cities in Western Europe include codes corresponding to: BER and PAR: Berlin, Paris, Milan, Rome, Amsterdam, Hamburg, Frankfurt, Vienna, Barcelona, Madrid. LON: London.
4. Press [Button A] to exit the setting mode.

Your watch will usually show the correct time after you select your city code. If not, the time will be adjusted automatically after the next signal reception (at midnight). You can also perform a forced signal reception or set the time manually.

If your area does not observe Daylight Saving Time, turn it off.

How to View Digital Time and Last Signal Screen

In the Current Time Mode, you can cycle through the digital time displays using [Button B] as shown in the figure.

[Diagram description: Shows digital time display with seconds, day of week, month/date, and AM/PM indicator.]

Radio Time Signal Reception

There are two methods of signal reception: automatic and forced.

• Automatic reception: The watch automatically receives the time signal five times a day at 0:00, 1:00, 2:00, 3:00, and 4:00 AM.
• Forced reception: You receive the signal by performing specific button operations (see "Forced Signal Reception").

Attention:

Before receiving the signal, remove the watch and place it near a window, away from metal objects, as shown in the figure. The 12 o'clock position of the watch should face the window. There should be no metal objects nearby.

[Diagram description: Shows a watch placed near a window, with arrows indicating optimal placement and distance from metal objects.]

Normal signal reception may be difficult or impossible under the following conditions:

• When near sources of electrical interference such as TVs, refrigerators, computers, or other household appliances.
• When near radio transmission stations, inside reinforced concrete structures, or in tunnels or underground areas.
• When near high-voltage power lines, neon signs, or radio stations that create interference.
• When near railways, highways, or airports.
• While riding in a train or car.

• Signal reception is generally better at night than during the day.
• The signal reception operation takes from 2 to 7 minutes, sometimes up to 14 minutes. Do not move the watch or press any buttons during this time.
• Your watch can receive calibration time signals transmitted from Rugby, England, and Mainflingen, Germany. The signal can be received within a range of approximately 1,500 km from the transmitter.
• At distances over 500 km from the transmitter, the signal may become weak, and reception may not occur under certain conditions.
• Even if the watch is within the reception range, the signal may not reach it due to mountains or other geological obstacles between the watch and the signal source.
• If you encounter problems, refer to the section "Possible Problems with Radio Signal Reception and Their Solutions."

About Automatic Signal Reception

When automatic time signal reception is enabled, the watch automatically starts receiving the signal at 0:00, 1:00, 2:00, 3:00 AM, and 4:00 AM daily. If none of these operations are successful, the reception operation will repeat at 5:00 AM.

[Diagram description: Shows the watch display with signal reception indicators, last signal date/time, and DST indicator.]

Forced Signal Reception

The signal reception operation is performed only in the Current Time or World Time modes, at the times specified above. Reception will not occur during an alarm sound or if the watch is in a setting mode (flashing display).

Automatic radio signal calibration occurs early in the morning while you are asleep. Before going to bed at night, remove the watch from your wrist and place it on a level surface in an area with the best possible signal reception.

When automatic signal reception is enabled, it takes 2 to 7 minutes each day. Do not operate the watch buttons within 5 minutes before or after signal reception, otherwise the time may be adjusted incorrectly.

Remember that signal reception depends on the time displayed on the watch's digital display. The reception operation will be performed each time the digital display shows 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m., regardless of whether the displayed time is accurate.

If the signal is successfully received two or three times, the watch uses the data from the last reception for calibration. If only one signal is successfully received, the watch uses the data from that reception.

About the Signal Reception Indicator

The signal reception indicator shows the quality of reception. The appearance of the indicator varies by watch model. For optimal reception, place the watch in an area of maximum signal strength.

[Diagram description: Shows signal reception indicator with levels: Level 0 (Weak Signal) and Level 3 (Strong Signal).]

Even in the optimal reception area, it takes approximately 10 seconds for the indicator to show a strong signal.

Use the indicator to check signal strength and find the best watch position during the reception operation.

The Level 3 signal reception indicator remains on the display in all modes after calibration signal reception and adjustment of the set time. Level 3 indicates that at least one signal was successfully received. However, note that the indicator is cleared from the screen every day at 3:00 AM.

Forced Signal Calibration Reception

1. Place the watch on a level surface with the 12 o'clock side facing the signal transmitter.
2. In the Current Time Mode, press and hold [Button D] for 2 seconds until the signal reception indicator flashes. The "RC!" indicator will appear.

The signal reception operation takes from 2 to 7 minutes, sometimes up to 14 minutes. Do not move the watch or press any buttons during this time.

After signal reception is complete, the last signal screen will be displayed.

Attention:

• To interrupt the signal reception and return the watch to the Current Time Mode, press [Button D].
• If the signal was not received, the message "ERR" will appear on the screen for one or two minutes. Then, the watch will return to the Current Time Mode.
• You can also switch from the error screen by pressing [Button D].

Setting Automatic Signal Reception

You can set the watch to receive signals from a specific transmitter or to automatically receive signals from the transmitter with the strongest signal. You can also disable automatic reception if desired.

How to Set Signal Reception

[Diagram description: Shows the watch display with indicators for AUTO, DCF, MSF, OFF.]

AUTO: Automatic signal reception. The watch automatically selects the transmitter with the strongest signal.

DCF: Automatic reception of the signal from Mainflingen.

MSF: Automatic reception of the signal from Rugby.

OFF: Automatic signal reception is turned off.

• For more details, refer to the "Transmitters" section.

Note: If the automatic reception indicator does not appear after pressing [Button A] for a long time, it means the currently selected city code is not within the signal reception area. In this case, you cannot set automatic signal reception.

Note: Performing a forced signal reception also relies on the selected setting (AUTO, DCF, MSF).

Battery

This watch is equipped with a solar power system and a rechargeable battery that is charged by electricity converted from solar energy.

Important!

• Storing the watch in the dark for extended periods, wearing it on the inside of your wrist, or covering the watch with clothing can significantly reduce battery power. Ensure the watch is exposed to light whenever possible.
• Your watch contains a solar cell that converts sunlight into electrical energy, charging the built-in rechargeable battery. Generally, this battery does not require replacement. However, after a long period of use (several years), the rechargeable battery may lose its ability to fully recharge. If these problems occur, contact your CASIO dealer or distributor for battery replacement.
• Never attempt to replace the battery yourself. Using an incorrect battery may damage the watch.
• Replacing the battery will erase all data from memory.
• Remember to set the watch to Power Saving Mode and place it in a well-lit area when storing the watch for extended periods.

Battery Power Indicator

The battery power indicator on the screen shows the current charge status of the rechargeable battery.

A flashing CHARGE-L indicator at Level 3 informs you that the battery is low and you should place the watch in light as soon as possible.

At Level 4, all functions stop working. They will become available again if the rechargeable battery is charged, but the data previously stored in memory will be lost. Therefore, after the battery is charged and the watch moves from Level 4 to Level 2, you must set the current time and date. Although the current time may appear on the screen after moving to Level 3, you cannot adjust it until the watch reaches Level 2.

Battery Power Indicator

If the watch is exposed to direct sunlight or another very strong light source, the battery power indicator may momentarily show a higher level than the actual charge. The correct indicator should appear after a few minutes.

Frequent use of the backlight and audible alarms places a heavy load on the battery, which may cause the RECOVER indicator to appear on the screen, indicating that backlight, audible alarms, digital/analog time synchronization, and signal reception functions are temporarily unavailable. Normal operation is usually restored after the battery charge recovers and the message disappears from the screen.

Precautions for Battery Charging

Avoid overheating the watch while charging the battery. The following are places where it is not advisable to charge your rechargeable battery:

• On a car dashboard parked in the sun.
• Too close to an incandescent lamp.
• Under direct sunlight or intense heat for extended periods.

Timekeeping Mode

This mode is used for setting and viewing the time and date. It also explains how to set the time and date manually.

When setting the time, you can also set the backlight duration, select the 12/24-hour format, and enable/disable the power saving mode.

[Diagram description: Shows the watch display in Timekeeping Mode with indicators for mode, day of week, month/date, seconds, and AM/PM.]

Setting Time and Date Manually

Auto-Return Function

If you do not press any buttons for two or three minutes while a cursor or digit is flashing in a setting mode, the flashing will stop, the watch will automatically memorize all entered values, and exit the setting mode.

If you do not perform any operations for two or three minutes in the Alarm or Hand Setting modes, the watch will automatically return to the Current Time Mode.

Radio Signal Reception Instructions

Strong electromagnetic fields can interfere with correct time setting. Even if you are within the transmitter's range, the signal may be blocked by mountains or other geological obstacles between the watch and the signal source.

Signal reception quality depends on weather, atmospheric conditions, and seasonal changes. The time signal travels through the ionosphere. Therefore, due to factors such as changes in the ionosphere's reflective capacity and its upward movement related to seasonal atmospheric changes or time of day, the signal reception range may change, or reception may not be possible for a period.

Setting the time according to the received signal takes priority over any other settings.

Automatic date and day of week updates upon calibration signal reception will occur from January 1, 2000, to December 31, 2099. Starting January 1, 2100, date setting will no longer be performed.

Signals received by the watch for leap years differ from normal years.

Although the watch should receive time (hours, minutes, seconds) and date (year, month, day) information, under certain conditions, only the time signal may be received.

When all five signals are successfully received, the watch uses the data from the last signal for adjustment. If only one signal is successfully received, the data from that signal is used for adjustment.

The watch normally receives time and date signals, and this information is shown on the Last Signal screen. If only the time signal is received, the current date will be displayed on the Last Signal screen.

If you are in an area where the signal is not received, the watch continues to display the time with the accuracy specified in the technical specifications.

If you encounter problems with signal reception, or if the display is incorrect after signal reception, check the city code, Daylight Saving Time, or automatic reception settings. The factory default settings are as follows:

Transmitters

Your watch is designed to receive time signals transmitted from Rugby, England, and Mainflingen, Germany. You can select one of these transmitters or set the watch to automatically select the transmitter with the strongest signal.

The following describes how the watch determines which transmitter to check first when set to automatic transmitter search:

Module 3361, 3726

Module 3360, 3725

Since the AUTO setting checks signals from both transmitters, signal reception may take up to 14 minutes.

Timekeeping Mode

Resetting the seconds to 00 will add 1 to the minute count if the seconds were between 30 and 59 at the moment [Button D] was pressed. If the seconds were between 00 and 29, the minutes will not change.

The day of the week is set automatically according to the date.

The year can be set from 2000 to 2099.

The watch includes an automatic perpetual calendar with correct day counts for months and leap year adjustments. Once you set the date and time, you may not need to adjust them again, except in cases where battery power drops to Level 4.

The current time for all cities is calculated based on the difference from Greenwich Mean Time for each city, using the Local Time set in the Current Time Mode.

The watch calculates the difference from Greenwich Mean Time based on Coordinated Universal Time (UTC) data.

12-/24-Hour Time Format

The 12- or 24-hour timekeeping system selected in the Current Time Mode applies to all other modes as well.

• When using the 12-hour format, the PM indicator appears to the left of the hour value for times from noon to 11:59 PM. The indicator is absent for times from midnight to 11:59 AM.
• When using the 24-hour format, time is displayed from 0:00 to 23:59 without an indicator.

Backlight Operation

The backlight is difficult to see when direct sunlight falls on the watch.

The backlight automatically turns off during alarm sounds.

Frequent use of the backlight reduces battery life.

Attention:

• The auto-illumination will automatically turn off when the battery level drops to Level 3.
• The watch is not intended to be worn on the inside of the wrist, as unintentional activation of the auto-illumination may occur, reducing battery life. If you wish to wear the watch on the inside of your wrist, disable this function.
• If the watch is covered by your clothing sleeve, the auto-illumination may activate frequently, leading to a rapid drop in battery power.
• The backlight may not activate for up to 1 second after you perform the above actions.
• You may hear a faint clicking sound accompanying the movement of your hand. This sound is caused by the activation and deactivation of the auto-illumination and does not indicate a malfunction.
