Operation Guide 5371
ENGLISH
Congratulations upon your selection of this CASIO watch.
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 this product or its malfunction.
E-1
Important!
•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 altimeter of this watch for mountain climbing or other activities, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information. For more information, see “To specify a reference altitude value” (page E-66).
•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.)

|
|
|
|
Warning!
Leaving the watch in bright light for charging 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
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-19) 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
In any mode, hold down B for at least two seconds. The battery power indicator will appear on the digital display, and then the watch will enter the Timekeeping Mode.
You can get an idea of the watch’s power level by observing the battery power indicator on the display.

•The flashing L indicator at Level 3 (L) tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
•Once the battery reaches Level 2 (M) after falling to Level 5, reconfigure the current time, date, and other settings.
•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
•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.
•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.

|
|
jump at 2-second intervals in the Timekeeping Mode to let you know that |
|
charging is required. |
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.
E-16 |
E-17 |
|
|
•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.
Power Saving
When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.
•For information about enabling and disabling power saving, see “To turn Power Saving on or off” (page E-99).
•There actually are two sleep state levels: “display sleep” and “function sleep”.

•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.
•Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.
•If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications”.
•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).

•The displayed DST setting will not change if you rotate the crown towards you.
•After you change the Home City and/or DST setting, the hour and minute hands will automatically move to the appropriate time setting. The time shown on the digital display will also change accordingly.
•The Auto DST (AUTO) setting will be available only when a city code that supports time calibration signal reception (page E-20) is selected as the Home City. While Auto DST is selected the DST setting will be changed automatically in accordance with time calibration signal data.
•Note that you cannot switch between standard time and daylight saving time (DST) while UTC is selected as your Home City.
5.After the settings are the way you want, push the crown back in.
•Daylight Saving Time is turned on when the DST indicator is on the display.
Note
•After you specify a city code, the watch will use UTC* offsets in the World Time Mode to calculate the current time for other time zones based on the current time in your Home City.
* Coordinated Universal Time, the world-wide scientific standard of timekeeping. The reference point for UTC is Greenwich, England.
•Selecting some city codes automatically makes it possible for the watch to receive the time calibration signal for the corresponding area. See page E-20 for details.

Hand Home Position Adjustment
If the watch is exposed to strong magnetism or impact, its hands can go out of alignment with the time on the digital display. This can result in incorrect time indication even though a time calibration signal is being received. Your watch has an auto hand position correction feature that normally adjusts the hands. Should you notice that the hand positions are not correct, perform the operation below to correct them manually.
To adjust home positions
Wait until all of the hands move to 12 o'clock.
Note
1.In the Timekeeping Mode, pull out the crown.
2.Hold down A for at least five seconds until HAND SET flashes and then HAND ADJ appears on the digital display.
•This will start home position adjustment, which causes all of the watch hands to move to 12 o’clock.
• After the hands stop moving, |
will appear on the digital |
display. |
|
Important!
•Before performing step 3, below, make sure that all hands have returned to the 12 o’clock position. Pushing the crown back in while any hand is not at the 12 o’clock position will not perform home position adjustment.
3.Push the crown back in.
•This will cause all of the hands (small hand, hour hand, minute hand, second hand) to return to their normal positions.
After performing home position adjustment, enter the Timekeeping Mode and check to make sure that the analog hands and the display indicate the same time. If they do not, perform home position adjustment again.
