General Guide

Press C to change from mode to mode.
In any mode, press L to illuminate the digital dials.
If the Power Saving indicator ( ) is flashing on the top dial, it means that the digital dials are blank because the watch’s Power Saving function has turned them off to conserve power. Power Saving automatically turns off the digital dials and enters a sleep state whenever your watch is left for a certain period in an area where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.
The initial factory default setting is Power Saving on.
The watch will recover from the sleep state if you move it
to a well-lit area, if you press any button, or if you angle the watch towards your face for reading.
See “Power Saving Function” for more information.

Current Time Setting
This watch automatically adjusts its time setting in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.
The first thing you should do after purchasing this watch is to set your Home City, which is the city where you will normally use the watch. For more information, see “To set your Home City” below.
When using the watch in an area that is outside of the range of the transmitters in Rugby and Mainflingen, you need to manually adjust the time as required. See “Timekeeping” for information about manual settings.
The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is automatically adjusted whenever you change the digital setting. See “Analog Timekeeping” for more information.

3. Press A to exit the setting screen.
Normally, your watch should show the correct time as soon as you select your Home City Code. If it does not, it should adjust automatically after the next auto receive (in the middle of the night). You can also perform manual receive or you can set the time manually.
If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.
This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.
This watch is designed to pick up the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany.
1. In the Timekeeping Mode, hold down A until the city

Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.
Auto Receive
With auto receive, the watch automatically picks up the time calibration signal five times a day at midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more information, see “About Auto Receive”.
Manual Receive
Manual receive lets you start a time calibration signal reception with the press of a button. For more information, see “To perform manual receive”.
Important!
When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. Make sure there are no metal objects nearby.
The watch should not be on its side or facing the wrong way.
Proper signal reception can be difficult or even impossible under the conditions listed
below.

Operation Guide 3360 3361
Signal reception is normally better at night than during the day.
Time calibration signal reception 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 operations or move the watch while time calibration signal reception is in progress.
1,500 kilometers
Rugby
500 kilometers
This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany. Signal reception is possible within the area represented by a circle with a radius of about 1,500 kilometers.
At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interference may also cause problems with reception.
See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful.
Note
Auto receive 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 a calibration time is reached while an alarm is sounding, or while you are configuring settings (while a setting is flashing in a digital dial).
Auto receipt of the calibration signal is designed to be performed early in the morning, 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.
When auto receive is turned on, the watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the five calibration times. Do not perform any button operation within seven minutes before or after any of the five calibration times. Doing so can interfere with correct calibration.
Remember that reception of the calibration signal depends on the digital time kept by the Timekeeping Mode. Reception will be performed whenever the Timekeeping Mode time reaches one of the five calibration times, regardless of whether or not the Timekeeping Mode time is actually the correct time.
When two, three, four, or five 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.
About the Receiving Indicator
The receiving 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.
Receiving indicator
Weak Strong
(Level 0)
Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.
Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal reception.
The Level 3 receiving indicator remains displayed on the top dial in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The Level 3 receiving indicator is not displayed on the top dial if signal reception was unsuccessful or after manual adjustment of the current time setting.
The Level 3 receiving indicator indicates that at least one of the five calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared at 3:00 a.m. each day.

Illumination

Auto light switch indicator
About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on whenever you position your wrist as described below in any mode. Note that this watch features a Full Auto Light,” so the auto light switch operates only when available light is below a certain level. It does not illuminate the digital dials under bright light.
Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.
Wear the watch on the outside of your wrist.
Warning!
Always make sure you are in a safe place whenever you are reading the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not surprise or distract others around you.
When you are wearing the watch, make sure that its auto light switch is turned off before riding on a bicycle, or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In any mode, hold down L for about two seconds to toggle the auto light switch on (auto light switch indicator displayed on the top dial) and off (auto light switch indicator not displayed).
The auto light switch is automatically turned off whenever battery power is at Level
4. After battery power recovers to Level 2, you will have to perform the above procedure to turn the auto light switch back on again.
The auto light switch indicator remains in all modes while the auto light switch is turned on.
An LED (light-emitting diode) and light guide panel illuminate the digital dials for easy reading in the dark. The watchs auto light switch automatically illuminates the digital dials when you angle the watch towards your face.
The auto light switch must be turned on (indicated by the auto light switch indicator) for it to operate.
See “Illumination Precautions for other important information.
To turn on illumination manually
In any mode, press L to illuminate the digital dials.
You can specify 1.5 seconds or 2.5 seconds as the illumination duration. See To set the current digital time and date manually” for more information.
The above operation turns on illumination regardless of the current auto light switch setting.

Power Supply

This watch is equipped with a solar cell and special rechargeable batteries (secondary batteries) that are charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face
is pointing at a light source.
The illustration shows how to position a watch with a resin band.
Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.
Normally, you should try to keep the watch outside of your sleeve as much as possible. Charging is significantly reduced if the face is only partially covered.
Important!
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 rechargeable battery power to run down. Make sure that the watch is normally exposed to bright light whenever possible.
This watch uses special rechargeable batteries to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable batteries may lose its ability to achieve a full charge. If you experience problems getting the special rechargeable batteries to fully charge, contact your dealer or CASIO distributor about having them replaced.
Never try to remove or replace the watch’s special batteries yourself. Use of the wrong type of batteries can damage the watch.
All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 4 and if you should ever need to have the rechargeable batteries replaced.
Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable batteries from going dead.
Battery Power Indicator and Recover Indicator
The battery power indicator shows you the current power level of the rechargeable batteries.
Recover indicator
Battery power indicator
The flashing charge indicator ( very low, and that exposure to bright light for charging is required as soon as possible.
At Level 4, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable batteries are charged, but you need to set the time and date, after the batteries reach Level 3 (indicated by the flashing charge indicator) from Level 4. You will not be able to configure any of the other settings until the batteries reach Level 2 (no charge indicator) after dropping to Level 4.
Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to momentarily show a reading that is higher than the actual battery level. The correct battery power indicator should appear after a few minutes.
If you use the light or alarms a number of times during a short period, the recover indicator appears and the following operations become disabled until battery power recovers.
Illumination Beeper tone Coordination between digital and analog timekeeping Time calibration signal reception
After some time, battery power will recover and the recover indicator will disappear, indicating that the above functions are enabled again.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable batteries. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.
Warning! Leaving the watch in bright light to charge its rechargeable batteries 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
Charging Guide
After a full charge, timekeeping remains enabled for up to about 7 months.

Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the digital 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 Rugby and Mainflingen include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the received time signal.
The default DST setting is Auto DST (
LON, or ATH as your Home City code.
If you experience problems receiving the time calibration signal in your area, it is probably best to switch between Standard Time and Daylight Saving Time (summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the city code starts to flash in the
bottom dial, which indicates the setting screen.
2. Press C once and the DST setting screen will appear in the bottom dial.

Auto Return Features
If you leave the watch in the Alarm or Hand Setting Mode for two or three minutes without performing any operation, it automatically returns to the Timekeeping Mode.
If you leave the watch with a flashing setting in a dial for two or three minutes without performing any operation, the watch automatically exits the setting screen.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll through data. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you last exited the mode appears first.
Radio-controlled Timekeeping Precautions
Strong electrostatic charge can result in the wrong time being set.
Even when the watch is within the reception range of the transmitter, signal
reception will be 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 bounces 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.
Even if the time calibration signal is received properly, certain conditions can cause the time setting to be off by up to one second.
The current time setting in accordance with the time calibration signal takes priority over any time settings you make manually.
The watch is designed to automatically update the date and day of the week for the period January 1, 2000 to December 31, 2099. Setting of the date by the time calibration signal cannot be performed starting from January 1, 2100.
This watch can receive signals that differentiate between leap years and non-leap years.
Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signal conditions can limit reception to time data only.
Normally, the signal reception date shown by the last signal screen is the date data included in the received time calibration signal. When only time data is received, however, the last signal screen shows the date as kept in the Timekeeping Mode at the time of signal reception.
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.
If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your current city code, DST (summer time), and auto receive settings. The following are the initial factory defaults for these settings.

Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany. You can select either one of the transmitters, or you can configure the watch to automatically select the transmitter that has the strongest signal.

Timekeeping
Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00
without changing the minutes.
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.
The watchs built-in full automatic calendar 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 batteries replaced or when batter y power drops to Level 4.
The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting.
GMT differential is calculated by this watch based on Universal Time Coordinated (UTC*) data.
* UTC is the world-wide scientific standard of timekeeping. It is based upon carefully
maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation. The reference point for UTC is Greenwich, England.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also applied in all other modes.
With the 12-hour format, the PM indicator ( in the range of noon to 11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m.
With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.
Illumination Precautions
Illumination may be hard to see when viewed under direct sunlight.
Illumination automatically turns off whenever an alarm sounds.
Frequent use of illumination runs down the batteries.
Auto light switch precautions
The auto light switch is turned off automatically whenever battery power is at Level 3.
Wearing the watch on the inside of your wrist, movement of your arm, or vibration of
your arm can cause frequent activation of the auto light switch and illumination of the digital dials. To avoid running down the batteries, turn off the auto light switch whenever engaging in activities that might cause frequent illumination.
Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the digital dials and can run down the batteries.
More than 15 degrees too high
Under certain conditions, illumination may not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch.
You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
back cover. The Module number (3360 or 3361) is engraved inside the box on the back cover.
) appears on the bottom dial for times
Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground.
Illumination turns off after the preset illumination duration (see To set the current digital time and date manually”), even if you keep the watch pointed towards your face.
Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.
