Operation Guide 5578

Congratulations upon your selection of this CASIO watch.

To ensure that this watch provides you with the years of service for which it is designed, carefully read and follow the instructions in this manual, especially the information under “Operating Precautions” and “User Maintenance”.

Keep all user documentation handy for future reference.

Applications

The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude. Measured values are then shown on the display. Such features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

Warning !

•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.

•When engaging in mountain climbing or other activities in which losing your way can create a dangerous or life-threatening situation, always use a second compass to conﬁrm direction readings.

•Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you or any third party arising through the use of your watch or its malfunction.

ENGLISH

Important Altimeter and Compass Information!

•The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure readings produced by its pressure sensor. This means that readings taken at different times at the same location may produce different altitude values due to changes in barometric pressure. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

•When using the watch’s altimeter while mountain climbing, be sure to perform regular calibration in accordance with the local altitude (elevation) indications. For more information, see “To specify a reference altitude value” (page E-56).

•Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other activities, be sure always to take along another compass to conﬁrm readings. If the readings produced by the digital compass of this watch are different from those of the other compass, perform bidirectional calibration of the digital compass to ensure more accurate readings.

•Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or electrical household appliances (TV, computer, cellphone, etc.)

Important!

•Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or totally white, depending on the watch model). The appearance of the LCD should become normal again when the watch returns to a lower temperature.

•Turn on the watch’s Power Saving function (page E-18) and keep it in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.

•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 power to run down. Expose the watch to bright light whenever possible.

Power Levels

Hold down B for at least two seconds to enter the Timekeeping Mode.

You can get an idea of the watch’s power level by observing the battery power indicator on the display.

•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.

•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 battery replaced.

A dark environment while battery power is at Level 4 will cause the level to drop to Level 5. Expose the watch to bright light whenever possible.

Low battery alert

Jumps at two-second

intervals When battery power reaches Level 3, the second hand of the watch will jump at 2-second intervals in the Timekeeping Mode to let you know that

Power Recovery Mode

•Performing multiple sensor, illumination, or beeper operations during a short period may cause the recovery indicator (RECOVER) to start ﬂashing on the display. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.

•Battery power will recover in about 15 minutes. At this time, the recovery indicator (RECOVER) will stop ﬂashing. This indicates that the functions listed above are enabled again.

•Frequent ﬂashing of the recovery indicator (RECOVER) indicates that battery power is low. Expose the watch to bright light as soon as possible.

•Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer Mode, Thermometer Mode or Altimeter Mode sensor may be disabled if there is not enough power available to power it sufﬁciently. This is indicated when the recovery indicator (RECOVER) are ﬂashing.

•Frequent ﬂashing of the recovery indicator (RECOVER) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

•The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

•The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

•The watch will not enter a sleep state while barometric pressure change indicator is enabled (page E-73).

To recover from the sleep state

Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page E-96).

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Conﬁ guring Current Time and Date Settings Manually” (page E-36) for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

Radio-controlled Atomic Timekeeping Precautions

•Strong electrostatic charge can result in the wrong time setting.

•Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.

•The watch is designed to update the date and day of the week automatically for the period January 1, 2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.

•If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Speciﬁcations”.

E-26	E-27

•The receive operation is disabled under any of the following conditions.

–While power is at Level 3 (L) or lower (page E-14)

–While the watch is in the power recovery mode (page E-16)

–While a direction, barometric pressure, temperature, or altitude reading operation is in progress

–When the watch is in the function sleep state (“Power Saving”, page E-18)

–While barometric pressure change indicator is being measured

–While a countdown timer operation is in progress (page E-86)

•A receive operation is cancelled if an alarm sounds while it is being performed.

•The Home City setting reverts to the initial default of TYO (Tokyo) 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 (page E-34).
