Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

• This watch is designed to pick up the time calibration signal transmitted in Germany (Mainflingen), England (Rugby), and the United States (Fort Collins) and the time calibration signals transmitted in Japan.

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.

• The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see “To specify your Home City” below.

• When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See settings.

•

The U.S. time calibration signal can be picked up by the watch while in North America.

* The term “North America” in this manual refers to the area that consists of

Canada, the continental United States, and Mexico.

3. Press E 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 operation (in the middle of the night). You also can perform manual receive or you can set the time manually.

• The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Transmitters”.

• See the maps under “Reception Ranges” for information about the reception ranges of the watch.

• You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

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 receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

• Manual Receive

Manual receive lets you start a time calibration receive operation 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 facing the wrong way.

• Proper signal reception can be difficult or even impossible under the

conditions listed below.

Operation Guide 3047

• The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

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. The receiving indicator is displayed while an auto or manual receive operation is in progress.

Receiving indicator

Weak

(Level 1)

• 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 receive operations.

• Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 5 receiving indicator will remain on the display in all modes. The Level 5 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

• The Level 5 receiving indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.

• The Level 5 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 5 receiving indicator disappears from the display each day when the first auto receive operation of the day is performed.

• In some areas, barometric pressure is expressed in millibars (mb) instead of hecto-pascals (hPa). It really makes no difference, because 1hPa = 1mb.

• You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “To specify barometric pressure and temperature units”.

• See “Barometer and Thermometer Precautions” for impor tant precautions.

Barometric Pressure Graph

Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. In every mode except for the Depth Gauge Mode, your watch takes barometric pressure readings every two hours (at the top of each even-numbered hour). Measurement results are used to produce barometric pressure graph and barometric pressure differential pointer readings. The barometric pressure graph shows readings of previous measurements for up to 30 hours. The horizontal axis of the graph represents time, with each dot standing for two hours. The rightmost dot (flashing) represents the most recent reading. The ver tical axis of the graph represents barometric pressure, with each dot standing for the relative difference between its reading and that of the dots next to it. Each dot represents 1hPa. The following shows how to interpret the data that appears on the barometric pressure graph.

A rising graph generally means improving weather.

A falling graph generally means deteriorating weather.

Note that if there are sudden changes in weather or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize. The following conditions cause the barometric pressure measurement to be skipped, with the corresponding point on the barometric pressure graph being left blank.

Barometric Pressure Differential Pointer

This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph, and the current barometric pressure value displayed in the Barometer/ Thermometer Mode.

• Pressure differential is indicated in the range of ±15 hPa, in 1-hPa units.

• The barometric pressure differential pointer is not displayed when the

displayed current barometric value is outside of the allowable measurement range (600 to 1,100 hPa).

• Barometric pressure is calculated and displayed using hPa as the standard. The barometric pressure differential also can be read in inHg units as shown in the illustration.

Depth Gauge

The pressure sensor of the watch also can be used to perform underwater depth measurement while skin diving or snorkeling. Depth readings are taken every three seconds, and displayed as a value up to 30 meters (98 feet). You can store the data of your last dive in log memory, including total time submerged, maximum depth, and water temperature at the maximum depth attained during your dive. You can view the log data of your last dive before beginning a new dive, and even take direction readings while in the Depth Gauge Mode.

Important!

• This watch is intended for use up to skin diving and snorkeling. Never use this watch while scuba diving.

• This watch is designed to start depth measurement and record data in memory after a depth of 1 meter (4 feet) is reached. Because of this, the explanations in this manual uses the term “submerged” to refer to any depth deeper than 1 meter, and the “on the surface” to refer to any depth shallower than 1 meter.

•

Leaving the watch in the Depth Gauge Mode while not in the water consumes battery power. Exit the Depth Gauge Mode whenever you are not using it.

What is “a dive”?

A dive starts when you pass a depth of one meter (about four feet) while the watch is in the Depth Gauge Mode. The dive ends when you are on the surface and exit the Depth Gauge Mode. A dive does not end if you surface but do not exit the Depth Gauge Mode.

Enter the Depth Gauge Mode. Exit the Depth Gauge Mode.

• Remember that the term “dive” as used in this manual refers to skin diving or snorkeling only.

• The watch will start depth measurement automatically when the sensor detects that your depth exceeds one meter (about four feet).

• Depth measurement stops automatically whenever your depth becomes less than one meter (four feet).

• Depth measurement restarts whenever you re-submerge past one meter (four feet). All data that is measured between the star t of the dive and the end of the dive is treated as part of the same dive, no matter how many times you surface during the dive.

• Exiting the Depth Gauge Mode causes the data accumulated during the dive (time submerged, maximum depth attained, water temperature at maximum depth) to be stored in log memory.

• The elapsed time is displayed in minutes and seconds for the first hour. After the first hour, it switches to hours and minutes.

• Pressing E while your current depth is less than one meter will toggle the display between the graph and the temperature screens.

• If the watch stays at a depth of less than one meter and you do not perform any operation for about one hour, the watch will revert to the Timekeeping Mode automatically.

• The watch will not exit the Depth Gauge Mode if any value other than (or 0) is displayed for the depth when you press D. If (or 0) does not appear on the display even though you are on the surface (depth of less than 1 meter/4 feet), perform the procedure under “To reset the reference depth to 0 meters (feet) manually”.

• You can select either meters (m) or feet (ft) as the display unit for depth. For details, see "To specify the depth unit".

• See “Depth Data Recall Mode” for information about viewing dive data.

Important!

Note the following important precautions whenever using the Depth Gauge Mode.

Before Skin Diving/Snorkeling

• Before beginning a dive, check to make sure that none of the following marks are shown on the display.

❑ CHG (indicating a weak battery) ❑ RECOV (indicating a weak battery) ❑

• Make sure that

• Make sure that the watch is set to the correct time of day.

• Check the glass, case and band for cracks or chips.

• Make sure that the band is fastened securely around your wrist.

While Skin Diving/Snorkeling

• Check to make sure that timer operation and depth measurement are being performed properly.

• Take care when skin diving/snorkeling near rocks or coral to avoid scratching the watch.

After Skin Diving/Snorkeling

• To avoid corrosion, rinse your watch thoroughly with fresh water to remove salt water, dir t, etc. When possible, soak the watch in fresh water overnight to make sure that all salt is removed.

• When using a metal band, clean inside the gaps in the band occasionally using a soft toothbrush and soapy water. Failure to do so can result in corrosion of the timepiece, soiling of clothing or irritation to sensitive skin.

Depth Graph

Changes in depth are displayed in a graph in the Depth Gauge Mode. The contents of the graph are updated every three seconds whenever you enter the Depth Gauge Mode.

• The horizontal axis of the graph represents 3-second time increments, and the bar on the far right is the latest measurement result.

• The vertical axis represents depth values, in 5-meter steps.

• The graph always indicates depths in meters (m), even if you have feet (ft)

selected as the depth unit.

• If you press a button while a measurement operation is in progress, the measurement operation is stopped, and the graph is not updated.

• Manually resetting the reference depth to 0 meters will change the pressure reference value. Because of this, all of the graph’s data will be cleared.

• If an error occurs while a measurement operation is in progress, the graph bar for that measurement is left blank.

• Pressing E while at a depth of less than one meter will toggle between the depth graph and the temperature screen.

Depth Gauge Mode Precautions

• After you enter the Depth Gauge Mode, the watch takes a reference pressure reading automatically and sets the result a 0 meters (feet). This means that before starting a dive, you should enter the Depth Gauge Mode while at the water’s surface, never while the watch is submerged.

• A major change in air temperature or other phenomena while you are using the Depth Gauge Mode can cause the display to show a value other than 0 meters (feet) when you are at the surface of the water. If this happens, reset the reference depth to 0 meters (feet). See “To reset the reference depth to 0 meters (feet) manually” for more information.

Configuring the Countdown Timer

The following are the settings you should configure before actually using the countdown timer.

• Countdown start time and reset time

• Auto-repeat on/off

• Progress beeper on/off

Countdown start time

You can set a countdown start time from one minute to 60 minutes.

Auto-repeat

Whenever zero is reached, the watch beeps (auto-repeat timer alarm) and auto-repeat restarts the countdown automatically from the countdown start time you set. Turning off auto-repeat causes the countdown to stop and the countdown start time to appear on the display when the end of the countdown is reached. Auto-repeat will repeat up to 10 times.

Progress Beeper

The progress beeper actually includes two beepers: a reset time beeper and a reset period progress beeper.

• The reset time beeper and reset period progress beeper sound only while the progress beeper is turned on.

Reset Time Beeper

The reset time beeper is similar to the countdown end beeper. When the progress beeper is turned on, the watch beeps each second of the final 10 seconds before the countdown reaches the reset time.

Seconds

You can set a countdown timer start time in the range of one minute to 60 minutes. An alarm sounds when the countdown reaches zero. An auto-repeat feature causes the countdown to restart automatically when the end of a countdown is reached, and a progress beeper signals the progress of the countdown. All of this makes the countdown timer a valuable tool for timing the start of a yacht race.

• All of the operations in this section are performed in the Countdown Timer Mode, which you enter by pressing D.

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 EL Light”, so the auto light switch operates only when available light is below a certain level. It does not illuminate the display under bright light.

• The auto light switch is always disabled, regardless of its on/off setting, when any one of the following conditions exists.

While an alarm is sounding During sensor measurement While a bearing sensor calibration operation is being performed in the Digital Compass Mode While a receive operation is in progress in the Receive Mode

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.

Parallel to ground

Warning!

• Always make sure you are in a safe place whenever you are reading the display of 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 startle 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 the Timekeeping Mode, hold down L for about three seconds to toggle the auto light switch on (A. EL displayed) or off (A. EL not displayed).

• The auto light switch on indicator (A. EL) is on the display in all modes while the auto light switch is turned on.

• The auto light switch turns off automatically whenever battery power drops to Level 4.

• Watch illumination may not turn on right away if you raise the watch to your face while a barometric pressure operation is in progress.

Power Supply

This watch is equipped with a solar cell and a rechargeable battery (secondary battery) that is 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.

• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly 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. Be sure that the watch is exposed to bright light whenever possible.

• This watch uses a special rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the special rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.

• Never try to remove or replace the watch’s special battery yourself. Use of the wrong type of battery 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 5 and when you have the batter y 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 battery from going dead.

All functions disabled. All settings revert to factory defaults.

Recover indicator

• Even if battery power is at Level 1 or Level 2, the Digital Compass Mode, Barometer/Thermometer Mode, or Depth Gauge Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. This is indicated by RECOV on the display. If battery power goes low while a measurement operation is in progress, the value produced by the last successful measurement operation remains on the display. Attempting a measurement operation while battery power is too low will cause the display to go blank. Sensor operation should resume when battery voltage returns to normal levels.

•

If RECOV starts to flash on the display when you enter the Depth Gauge Mode (before starting measurement), the log data date will not be recorded if you start measurement after RECOV disappears from the display. In this case, exit and re-enter the Depth Gauge Mode, and then start the measurement again.

• If RECOV starts to flash while a Depth Gauge Mode depth measurement operation is in progress, the measurement operation will continue. Though the elapsed measurement time will be recorded in log memory, maximum depth and water temperature values are not. In this case, in place of the maximum depth and water temperature. After you surface from your dive, hold down D for about three seconds to exit the Depth Gauge Mode to clear RECOV.

• If RECOV appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

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 battery. 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 battery 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

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 Mainflingen (Germany), Rugby (England), or Fort Collins (the United States) include both Standard Time and DST data. When the Auto DST setting is tur ned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the signals.

• The time calibration signals transmitted from Fukushima and Fukuoka/Saga (Japan) do not include summer time data.

• The default DST setting is Auto DST (

Radio-controlled Atomic Timekeeping Precautions

• Strong electrostatic charge can result in the wrong time being set.

• 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, cer tain 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 update the date and day of the week automatically for the period January 1, 2001 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. 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, and DST (summer time), and auto receive settings.

• The Home City setting reverts to the initial default of whenever the battery power level drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the Home City to the setting you want.

Transmitters

The time calibration signal received by this watch depends on the currently selected Home City code.

• When a U.S. time zone is selected, the watch receives the time calibration signal transmitted from the United States (Fort Collins).

•

When a Japanese time zone is selected, the watch receives the time calibration signal transmitted from the Japan (Fukushima and Fukuoka/Saga)

• When a European time zone is selected, the watch receives the time calibration signals transmitted from Germany (Mainflingen) and England (Rugby). The following tables show the reception priority for the European signals.

Timekeeping

• The year can be set in the range of 2000 to 2099.

• The watch’s 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 battery replaced or when battery power drops to Level 5.

• The current time for all city codes in the Timekeeping Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential of each zone, 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.

Illumination Precautions

• The electro-luminescent panel that provides illumination loses power after very long use.

• Illumination may be hard to see when viewed under direct sunlight.

• Illumination turns off automatically whenever an alarm sounds.

• The watch may emit an audible sound whenever the display is illuminated.

This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.

• Frequent use of illumination runs down the battery.

• Illumination is disabled while the watch is taking a depth reading (every

three seconds).

Auto light switch precautions

• The auto light switch is turned off automatically whenever battery power is at Level 4.

• 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 display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display.

• Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery.

More than 15 degrees too high

• 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 toward 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.

• 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.

The watch does this:

1. Checks the Rugby signal first.

2. If the Rugby signal cannot be received, checks the Mainflingen signal.

Checks the signal of the transmitter of the first

1. receive operation (Rugby or Mainflingen).

2.If the checked signal cannot be received, checks the other signal.

• 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 in about one second, even if you keep the watch pointed towards your face.

Digital Compass Precautions

This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia. Note that the difference between magnetic nor th and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles. You should also remember that some maps indicate true north (instead of magnetic north), and so you should make allowances when using such maps with this watch.

Location

• Taking a direction reading when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.)

• Accurate direction readings are impossible while in a train, boat, air plane, etc.

• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc.

Storage

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of this, you should be sure to store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal computers, washing machines, freezers, etc.)

• Whenever you suspect that the watch may have become magnetized, perform one of the calibration procedures under “Calibrating the Bearing Sensor”.

Calibrating the Bearing Sensor

Whenever you suspect that direction readings produced by the watch are wrong, you should calibrate it. You can use either one of two calibration procedures: Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason. With northerly calibration, you “teach” the watch which way is north (which you have to determine with another compass or some other means). You could use this calibration procedure, for example, to set the watch to indicate true north instead of magnetic north.

Important!

• If you want to perform both bidirectional and northerly calibration, be sure

• The more correctly you perform bidirectional calibration, the better the

Barometer and Thermometer Precautions

• The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications.

• Sudden temperature changes can affect pressure sensor readings.

• Temperature measurements are affected by your body temperature (while

you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Calibrating the Temperature Sensor

The temperature sensor of this watch is calibrated at the factory before shipment, and further adjustment normally is not required. If you notice serious errors in the temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

Important!

Incorrectly calibrating the temperature sensor can result in incorrect readings. Carefully read the following before doing anything.

• Compare the readings produced by the watch with those of another reliable and accurate thermometer.

• If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.
