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

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.

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.

Using the Digital Compass While Mountain Climbing or Hiking

This section provides three practical applications for using the watch’s built-in digital compass.

• Setting a map and ﬁ nding your current location

Having an idea of your current location is important when mountain climbing or hiking. To do this, you need to “set the map”, which means to align the map so the directions indicated on it are aligned with the actual directions of your location. Basically what you are doing is aligning north on the map with north as indicated by the watch.

Digital Compass Precautions

This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia. Note that the difference between magnetic north and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles. You should also remember that some maps indicate true north (instead of magnetic north), and so you should make allowances when using such maps with this watch.

Location

• Taking a direction reading when you are near a source of strong magnetism can cause large errors in

readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.).

• Accurate direction readings are impossible while in a train, boat, air plane, etc.

• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is

because the metal framework of such structures picks up magnetism from appliances, etc.

Storage

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of

this, you should store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal computers, washing machines, freezers, etc.).

• Whenever you suspect that the watch may have become magnetized, perform the procedure under “To

perform bidirectional calibration” (page E-37).

E-46

1. Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location.

• See “To set a map an d ﬁ nd your curren t location” o n page E-4 2 for

informati on about ho w to perform t he above step.

2. As shown in the illustration to the left, change your position so you (and the 12 o’clock position of the watch) are pointed in the direction of objective, while keeping the northerly direction indicated on the map aligned with north as indicated by the watch.

• If you ﬁ nd it dif ﬁ cult to per form the ab ove step while ke eping

E-51

Important!

• To ensure proper results, take barometric readings under conditions where the altitude remains

constant.

Example

– In a lodge or campground – On the ocean

• A change in altitude causes a change in barometric pressure. Because of this, correct readings are

impossible. Do not take readings while ascending or descending a mountain, etc.

• The barometric pressure change indicator may appear at any time while the watch is in the Barometer/

Thermometer Mode. Keep in mind, however, that its indication will not be correct unless the watch has been in an location where there was no change in altitude over the past several hours.

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no further adjustment. If you notice serious errors in the pressure readings and temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

Important!

• Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before

performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer.

• Incorrectly calibrating the temperature sensor can result in incorrect readings.

Carefully read the following before doing anything. –

Compare the readings produced by the watch with those of another reliable and accurate thermometer.

– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the

temperature of the watch time to stabilize.

E-52

Barometer and Thermometer Precautions

• The pressure sensor built into this watch measures changes in air pressure, which you can then apply

to your own weather predictions. It is not intended for use as a precision instrument in ofﬁ cial weather prediction or reporting applications.

• Sudden temperature changes can affect pressure sensor readings.

• 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.

To calibrate the pressure sensor and the temperature sensor

1. Take a reading with another measurement device to determine the exact current barometric pressure or temperature.

2. With the watch in the Timekeeping Mode or in any of the sensor modes, press B to enter the Barometer/Thermometer Mode.

3. Hold down E until current settings start to ﬂ ash.

4. Press D to move the ﬂ ashing between the temperature value and barometric pressure value, to select the one you want to calibrate.

Taking Altitude Readings

The watch displays altitude values based on air pressure readings taken by a built-in pressure sensor.

How the Altimeter Measures Altitude

The altimeter can measure altitude based on its own preset values (initial default method) or using a reference altitude speciﬁ ed by you.

When you measure altitude based on preset values

Data produced by the watch’s barometric pressure sensor is converted to approximate altitude based on ISA (International Standard Atmosphere) conversion values stored in watch memory.

When you measure altitude using a reference altitude speciﬁ ed by you

After you specify a reference altitude, the watch uses that value to convert barometric pressure readings to altitude (page E-61).

• When mountain climbing, you can specify a reference altitude value in

accordance with a marker along the way or altitude information from a map. After that, the altitude readings produced by the watch will be more accurate than they would without a reference altitude value.

Note

• The high altitude, low altitude, total ascent, and total descent values are retained in memory when you

exit the Altimeter Mode. To clear values, perform the procedure under “To clear the contents of a speciﬁ c memory area” (page E-76).

Using Auto Save Values

The watch maintains two independent sets of auto save values as shown below.

The values in Set 1 and Set 2 can be cleared independently of each other. This means you can use them to keep track of daily and cumulative data as described in the example below.

Example:

Keeping track of data on a three-day climb

Day 1

Clear both Set 1 and Set 2, and start your Day 1 climb. At the end of the day, both sets of auto save values contain the same data (

MIN-2

, etc.).

How does the altimeter work?

Generally, air pressure and temperature decrease as altitude increases. This watch bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO). These values deﬁ ne relationships between altitude, air pressure, and temperature.

Altimeter Precautions

• This watch estimates altitude based on air pressure. This means that altitude readings for the same

location may vary if air pressure changes.

• The semiconductor pressure sensor used by the watch for altitude measurements is also affected by

temperature. When taking altitude measurements, do not subject the watch to temperature changes.

• Do not rely upon this watch for altitude measurements or perform button operations while sky diving,

hang gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other activity where there is the chance of sudden altitude changes.

• Do not use this watch for measuring altitude in applications that demand professional or industrial level

precision.

• Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings

produced by this watch will not match the altitude readings announced or indicated by the ﬂ ight crew.

Precautions Concerning Simultaneous Measurement of Altitude and Temperature

Though you can perform altitude and temperature measurements at the same time, you should remember that each of these measurements requires different conditions for best results. With temperature measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat. In the case of altitude measurement, on the other hand, it is better to leave the watch on your wrist, because doing so keeps the watch at a constant temperature, which contributes to more accurate altitude measurements.

• To give altitude measurement priority, leave the watch on your wrist or in any other location where the

temperature of the watch is kept constant.

• To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely

from your bag or in another location where it is not exposed to direct sunlight. Note that removing the watch from your wrist can affect pressure sensor readings momentarily.

Moon Phases and Moon Age

The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon appears to wax and wane as the relative positioning of the Earth, Moon, and Sun changes. The greater the angular distance between the Moon and the Sun,* the more we see illuminated.

* The angle to the Moon in relation to the direction at which the Sun is visible from the Earth.

This watch performs a rough calculation of the current Moon age starting from day 0 of the moon age cycle. Since this watch performs calculations using integer values only (no fractions), the margin for error of the displayed Moon age is ± 1 day.

Moon Phase Indicator

Moon phase indicator

Moon age

day is adjusted au tomatica lly based on t he ﬁ rst high ti de time.

The Moon phase indicator of this watch indicates the current phase of the Moon as shown below. It is based on the view of the left side of the moon at meridian transit from the northern hemisphere of the Earth. If the appearance of the Moon phase indicator is reversed from the actual Moon as viewed from your location, you can use the procedure under “To reverse the displayed Moon phase” (page E-81) to change the indicator.

Reversing the Displayed Moon Phase

The left-right (east-west) appearance of the Moon depends on whether the Moon is north of you (northerly view) or south of you (southerly view) as you view it. You can use the procedure below to reverse the displayed Moon phase so it matches the actual appearance of the Moon where you are located.

• To determine the viewing direction of the Moon, use a compass to take a direction reading of the Moon

at its meridian passage.

Tidal Movements

Tides are the periodic rise and fall of the water of oceans, seas, bays, and other bodies of water caused mainly by the gravitational interactions between the Earth, Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal interval. The Tide Graph calculates and graphically represents current tide conditions in your Home City or a port city in the vicinity of the Home City based on longitudes, lunar day length, and lunitidal interval preset in watch memory, and on high tide times speciﬁ ed by you.

Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about six hours later. Actual high tide occurs somewhat later, due to factors such as viscosity, friction, and underwater topography. Both the time differential between the Moon’s transit over the meridian until high tide and the time differential between the Moon’s transit over the meridian until low tide are known as the “lunitidal interval”.

About the Auto Light Switch

Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch

•

using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding

•

on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a trafﬁ c accident and serious personal injury.

Illumination Precautions

• The electro-luminescent panel that provides illumination loses power after very long use.

• Illumination may be hard to see when viewed under direct sunlight.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the battery.

Auto light switch precautions

• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can

cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display.

• Note that wearing the watch under your sleeve while the auto light switch is turned on can cause

frequent illumination of the display and can run down the battery.

• Illumination may not turn on if the face of the watch is more than 15 degrees above

or below parallel. Make sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination duration (page E-97), even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with proper operation of the auto

light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.

Why am I having problems taking direction readings indoors?

■

A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism readings. Move away from the object causing the interference or take the direction reading outdoors. Indoor direction readings are particularly difﬁ cult inside ferro-concrete structures. Remember that you will not be able to take direction readings inside of trains, airplanes, etc.

Try performing the calibration procedure again from the beginning.

Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized CASIO distributor as soon as possible.

What causes incorrect direction readings?

■

• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-37).

• Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel

beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move away from large metal objects and try again. Note that digital compass operation cannot be performed inside a train, boat, etc.

What causes different direction readings to produce different results at the same location?

■

Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism. Move away from the high-tension wires and try again.

The display shows the ERR indicator when I check the result of the latest receive operation.
