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.

• 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 an 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.

•

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 conﬁ rm 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.

Important!

• 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.

• Turn on the watch’s Power Saving function (page E-13) 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

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

Charging the Watch

The face of the watch is a solar cell that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Whenever you are not wearing the watch, leave it in a location where it is exposed to light.

• Best charging performance is

achieved by exposing the watch to the strongest light available.

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

• The ﬂ ashing

bright light for charging is required as soon as possible.

• At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery

reaches Level 2 (M) after falling to Level 5, reconﬁ gure 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.

• 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.

Power Recovery Mode

• Performing multiple sensor, illumination, or beeper operations during a short period may cause all of

the battery power indicators (H,M, and L) to start ﬂ ashing 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 battery power indicators (H,M,L) will

stop ﬂ ashing. This indicates that the functions listed above are enabled again.

• If all of the battery power indicators (H,M,L) are ﬂ ashing and the C (charge) indicator also is ﬂ ashing,

it means the battery level is very 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/

Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufﬁ ciently. This is indicated when all of the battery power indicators (H,M,L) are ﬂ ashing.

• Frequent ﬂ ashing of all of the battery power indicators (H,M,L) probably means that remaining battery

power is low. Leave the watch in bright light to allow it to charge.

LOW

indicator at Level 3 (L) tells you that battery power is very low, and that exposure to

When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.

• The watch may enter a sleep state

(page E-13) if its face is blocked by your sleeve even only partially.

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-31) 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.

If your Home City Code setting is this:

LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainﬂ ingen (Germany)

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 and off”

(page E-102).

• There actually are two sleep state levels: “display sleep” and “function sleep”.

Elapsed Time in Dark Display Operation

60 to 70 minutes (display sleep) Blank, with PS ﬂ ashing Display is off, but all functions are enabled.

6 or 7 days (function sleep) Blank, with PS not ﬂ ashing

• 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.

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-98).

All functions are disabled, but timekeeping is maintained.

• Even when the watch is within range of a transmitter, signal reception may be impossible due to the

effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the inﬂ uence of the conditions listed above becomes even greater.

• Signal reception may not be possible at the distances noted below during certain times of the year or

day. Radio interference may also cause problems with reception. Mainﬂ ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles) Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles) Shangqiu (China) transmitter: 500 kilometers (310 miles)

• As of May 2011, China does not use Daylight Saving Time (DST). If China does go to the Daylight

Saving Time system in the future, some functions of this watch may no longer operate correctly.

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 “Speciﬁ cations”.

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

– While power is at Level 3 (L) or lower (page E-10) – While the watch is in the power recovery mode (page E-11) – While a sensor operation is being performed – When the watch is in the function sleep state (“Power Saving”, page E-13) – While a countdown timer operation is in progress (page E-91)

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

• The Home City setting reverts to the initial default of

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-28) .

Digital Compass Readings

• When you press Cto start digital compass measurement,

indicate that a digital compass operation is in progress.

• About two seconds after you start a digital compass measurement operation, letters on the display will

indicate the direction that the 12 o’clock position of the watch is pointing. Four pointers that indicate magnetic north, south, east, and west will also appear.

• After the ﬁ rst reading is obtained, the watch will continue to take digital compass readings automatically

each second for up to 20 seconds. After that, measurement will stop automatically.

• The direction indicator and angle value will show

complete.

• The auto light switch is disabled during the 20 seconds that digital compass readings are being taken.

• The following table shows the meanings of each of the direction abbreviations that appear on the

display.

• The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is

horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees.

• Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in

large measurement error.

•

You can calibrate the bearing sensor if you suspect the direction reading is incorrect.

• Any ongoing direction measurement operation is paused temporarily while the watch is performing an

alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressing L). The measurement operation resumes for its remaining duration after the operation that caused it to pause is ﬁ nished.

• See “Digital Compass Precautions” (page E-46) for important information about taking direction readings.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. You can use any one of three different bearing sensor calibration methods: bidirectional calibration, northerly calibration, or magnetic declination correction.

Bidirectional Calibration and Northerly Calibration

•

Bidirectional calibration and northerly calibration calibrate the accuracy of the bearing sensor in relation to magnetic north. 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).

Important!

The more correctly you perform bidirectional calibration, the better the accuracy of the bearing sensor readouts. You should perform bidirectional calibration whenever you change environments where you use the bearing sensor, and whenever you feel that the bearing sensor is producing incorrect readings.

direction.

To perform northerly calibration

Important!

If you want to perform both northerly and bidirectional calibration, perform bidirectional calibration ﬁ rst, and then perform northerly calibration. This is necessary because bidirectional calibration cancels any existing northerly calibration setting.

1. In the Digital Compass Mode, hold down E until

2. Press D twice to display the northerly calibration screen.

Magnetic Declination Correction

•

With magnetic declination correction, you input a magnetic declination angle (difference between magnetic north and true north), which allows the watch to indicate true north. You can perform this procedure when the magnetic declination angle is indicated on the map you are using. Note that you can input the declination angle in whole degree units only, so you may need to round off the value speciﬁ ed on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.

Precautions about bidirectional calibration

• You can use any two opposing directions for bidirectional calibration. You must, however, make sure

that they are 180 degrees opposite each other. Remember that if you perform the procedure incorrectly, you will get wrong bearing sensor readings.

• Do not move the watch while calibration of either direction is in progress.

• You should perform bidirectional calibration in an environment that is the same as that where you plan

to be taking direction readings. If you plan to take direction readings in an open ﬁ eld, for example, calibrate in an open ﬁ eld.
