Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Keep the watch exposed to bright light

Bright light

Solar cell

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will cause some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light. Battery discharges in the dark.

Solar cell (Converts light to electrical power.)

• The actual level at which some functions are disabled depends on the watch model.

• Frequent display illumination can run down the battery quickly and require charging.

The following guidelines give an idea of the charging time required to recover from a single illumination operation.

Approximately five minutes exposure to bright sunlight coming in through a window

Approximately 50 minutes exposure to indoor fluorescent lighting

• Be sure to read “Power Supply” for important information you need to know when exposing the watch to bright light.

The electricity generated by the solar cell of the watch is

stored by a built-in battery. Leaving or using the watch

where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

• When you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.

• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.

Temperature Measurements

When you display the Temperature screen in the Timekeeping Mode, the watch starts taking automatic temperature readings at an interval of approximately two minutes.

• You can select either Celsius (°C) or Fahrenheit (°F) units for the Temperature screen. See “To specify the temperature display unit” for more information.

• The Temperature screen displays temperature values in 0.1°C units (or 0.2°F units).

• The display range of the temperature screen is –10.0°C to 60.0°C (or 14.0°F to

140.0°F).

• You can calibrate the Temperature sensor if you feel that the displayed temperature

values are not correct. See “Temperature Sensor Calibration” for more information.

Important!

• 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.

Tide Graph and Moon Phase Indicator

• The tide graph shows tidal movements for the current date in accordance with the current time as kept in the Timekeeping Mode.

• The Moon phase indicator shows the current Moon phase in accordance with the current date as kept in the Timekeeping Mode.

• Because the watch needs to read certain data, it takes about 40 seconds before the graph appears. The Moon phase indicator flashes while the watch is reading data.

Important!

• Moon phase indicator and tide graph data will not be displayed properly unless the Timekeeping Mode current date and time settings and Home Site data are configured correctly. See “Home Site Data” for more information.

Home Site Data

Note that tide graph data and the Moon phase indicator will not show the correct information unless your Home Site (city code and area) is specified correctly. World Time Mode times are all calculated based on the Home Site time and date setting in the Timekeeping Mode.

• First select the city code for your Home Site and specify the UTC differential. Next, specify the area that is nearest the location where you will be using the watch. Areas are preset with the names of coastal areas that match the city code and UTC differential you specify.

• The UTC differential indicates the time differential with Greenwich, England.

• The letters UTC is the abbreviation for Coordinated Universal Time, which 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 following is the initial factory default Home Site data (Tokyo, Japan) when you first purchase the watch and whenever you have the battery replaced. Change these settings to match the area where you normally use the watch.

Configuring Countdown Timer Settings

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

Countdown start time and reset time Timer type (auto-repeat, elapsed time)

• See “To configure countdown timer settings” for information about setting up the timer.

Reset Time

You can set a “reset time”, which is a kind of alternate countdown start time you can recall with the press of a button any time a countdown operation is in progress.

Timer Type

The countdown timer gives you a choice of two types of timer: auto-repeat and elapsed time.

Auto-repeat

Auto-repeat automatically restarts the countdown from the countdown start time whenever zero is reached.

• Auto-repeat is best when timing the starts of match races.

• Even if you start a countdown operation from the reset time, the countdown restarts

automatically from the countdown start time whenever it reaches zero.

• Auto repeat timing repeats up to seven times.

Elapsed Time

When the elapsed time timer reaches the end of the countdown, it switches to an elapsed time measurement operation automatically.

• The elapsed time timer is best when timing the speed of yachts during ocean races.

• The elapsed time operation is performed in one-second increments up to 99 hours,

59 minutes, 59 seconds.

Countdown Timer Beeper Operations

The watch beeps at various times during a countdown so you can keep informed about the countdown status without looking at the display. The following describes the types of beeper operations the watch performs during a countdown.

Countdown End Beeper

The watch beeps each second of the final 10 seconds before a countdown reaches zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal when the countdown reaches zero.

Progress Beeper

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

Reset Time Beeper

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

Reset Period Progress Beeper

The reset period is the portion of the countdown between the reset time and zero. While timing is the reset period, the watch will beep four times at the top of each minute and 30 seconds before the end of the countdown.

Countdown Timer Examples

Reset Time Beeper

The countdown timer can be set within a range of one minute to 60 minutes. An alarm sounds when the countdown reaches zero. The countdown timer has two modes: auto-repeat and elapsed time, 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 C.
