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.

• The measurement functions built into this watch are not intended for taking measurements that require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

• The Moon phase indicator and tide graph data that appear on the display of this watch are not intended for navigation purposes. Always use proper instruments and resources to obtain data for navigation purposes.

• This watch is not a precision instrument for calculating low tide and high tide times. The tide graph of this watch is intended to provide a reasonable approximation of tidal movements only.

Warning!

E-1

Keep the watch exposed to bright light

Bright Light

Solar cell

E-2

• 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 5 minutes exposure to bright sunlight coming in through a window Approximately about 8 hours exposure to indoor fluorescent lighting

• Be sure to read “Power Supply” (page E-52) for important information you need to know when exposing the watch to bright light.

If the display of the watch is blank...

If the display of the watch is blank, it means that the watch’s Power Saving function has turned off the display to conserve power.

• See “Power Saving Function” (page E-66) for more information.

E-4

The electricity generated by the solar cell of the watch is stored by a rechargeable 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.

• 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 result in 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.

Read This Before You Set the Time and Date!

This watch is preset with a number of city codes, each of which represents the time zone where that city is located. When setting the time, it is important that you first select the correct city code for your Home City (the city where you normally use the watch). If your location is not included in the preset city codes, select the preset city code that is in the same time zone as your location.

• Note that all of the times for the World Time Mode city codes (page E-36) are displayed in accordance with the time and date settings you configure in the Timekeeping Mode.

• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all other modes.

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.

E-16

Using the Diving Mode

You can use the Diving Mode to log records of the duration of each of your dives. Each record includes a log number, the dive time, and the dive start date and time. There is enough log memory to hold up to 10 dive records. You can use the Log memory Recall Mode to display dive records currently in log memory (page E-24).

• Hold down C to enter the Diving Mode as shown under “General Guide” on page E-10.

• If you leave the watch in the Diving Mode for about 11 to 12 hours, it will automatically switch to the Timekeeping Mode.

Measuring Units and Ranges

Dive Time

Unit: 1 second Range: 23:59'59'' (24 hours)

Dive Interval Time

Unit: 1 minute Range: 47:59' (48 hours)

• When the interval time exceeds the above range, interval time measurement automatically stops and the current interval time disappears from the screen of the newest dive record.

About the Interval

The interval is time that elapses between the stop of the last dive and the start of the next dive. The watch starts an interval measurement whenever you press A at the end of a dive to reset dive time measurement (page E-22).

• Note that the current ongoing interval time is shown on the screen of the newest record in log memory. It is not displayed in the Diving Mode. For information about viewing dive records, see page E-24.

E-20

To reset a dive time measurement and start interval measurement

While dive time measurement is stopped, press A.

• This creates a new dive record with the currently displayed dive time information and starts interval measurement. Current ongoing interval measurement is shown on the screen of the newly created record.

To reset a dive time measurement and exit the Diving Mode

While dive time measurement is stopped, hold down C for about one second.

• This creates a new dive record with the currently displayed information and exits the Diving Mode to the Timekeeping Mode.

• See “Dive records” on page E-24 for more information.

E-22

Important!

• Pressing D again after stopping dive time measurement will cause timing to resume from where it was stopped.

• Dive time/interval measurement continues internally if you exit the Diving Mode without resetting. A dive record is not created in this case.

Dive records

A new dive record is created whenever you reset a dive time measurement, either by pressing A to start interval measurement or by holding down C to exit the Diving Mode.

• Each dive record includes a log number, the dive time, the dive start date and time, and the interval prior to the dive (if there was one).

• There is enough memory for 10 dive records. If there are already 10 dive records in memory when you perform a reset operation, the oldest record currently in memory is deleted automatically to make room for the new record.

• The interval is displayed on the screen of the newest dive record, only while an interval timing operation is in progress.

Tide/Moon Data

In the Tide/Moon Data Mode, you can see the current tide and the current date’s moon phase for your Home City. You can specify a date and view tide and moon data for that date.

• See “Moon Phase Indicator” (page E-60) for information about the moon phase indicator and “Tide Graph” (page E-63) for information about the tide graph.

• All of the operations in this section are performed in the Tide/Moon Data Mode (page E-11).

Note

• It takes about two seconds to calculate tide graph data. You will not be able to display a setting screen while data calculation is in progress.

• Moon age is calculated to an accuracy of ±1 day.

To delete dive records

In the Log memory Recall Mode, hold down A for about three seconds.

• Keep A depressed for the full three seconds. During this time, message CLR will

flash on the display and then “-:--” will appear. Records will not be deleted if you release A before “-:--” appears. “-:--” indicates that all records have been deleted.

Note

• This procedure deletes all dive records. Dive records cannot be deleted individually.

• Note that you cannot delete records while a dive time measurement operation is in

progress.

Tide Data

The tide graph that appears first when you enter the Tide/Moon Data Mode shows the data at 6:00 a.m. for your currently selected Home City on the current date, according to the Timekeeping Mode. From there you can specify another date or time.

• If the tide data is not correct, check your Timekeeping Mode settings and correct them if necessary.

• The tide graph is displayed in the Timekeeping Mode, the Tide/Moon Data Mode, and the Diving Mode.

• If the watch is in the Diving Mode when there is a transition from one date to the next, the tide graph contents will not change to reflect the data for the new date. If you want to update the tide graph, exit and then re-enter the Diving Mode.

• If you feel that the information shown by the tide graph is different from actual tide conditions, you need to adjust the high tide time. See “Adjusting the High Tide Time” (page E-32) for more information.

Hold down A for about three seconds.
