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.

•

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.

Warning !

E-1

Important!

• Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure

measurement by its pressure sensor. For more information, see page E-36 and E-48.

• Immediately before embarking or otherwise taking altitude readings, be sure to specify a reference

altitude. If you don’t the readings produced by the watch probably will not be very accurate. For more information, see “To specify a reference altitude value” (page E-44).

Charging the Watch

The face of the watch is a solar panel 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

E-10

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-14) if its face is blocked by your sleeve even only partially.

E-100 Speciﬁ cations

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-14) 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.

Important!

• If low battery power is indicated, expose the face of the watch to direct light to charge. At Level 5, the

battery is dead, which causes watch functions to stop, all data in watch memory to be deleted, and all watch settings to return to their initial factory defaults.

• The above exposure times all are for reference only. Actual exposure times depend on lighting

conditions.

• For details about the operating time and daily operating conditions, see the “Power Supply” section of

the Speciﬁ cations (page E-103).

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-93).

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

• 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.

• Power Saving is enabled only when the watch is in the Timekeeping Mode with the Day of the Week

screen displayed (page E-29) or in the World Time Mode (page E-75).

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-89).

All functions are disabled, but timekeeping is maintained.

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

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.

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-33) 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)

below for details.

• Manual rec eive: Perfor m the operat ion under “ To perform ma nual receive” o n page E-19.

Auto Receive

• With auto receive, the watch performs the receive operation each day automatically up to six times (up

to ﬁ ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.

• When a calibration time is reached, the watch will perform the receive operation only if it is in the

Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is reached while you are conﬁ guring settings.

• 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.

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-11) – While the watch is in the power recovery mode (page E-13) – 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-14) – While the barometric pressure change indicator is displayed – While a countdown timer operation is in progress (page E-79)

• 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-31) .

During manual receive, the signal level indicator displays the signal level as shown below.

Weak (Unstable) Strong (Stable)

The level indication will change in accordance with reception conditions while reception is being performed. As you watch the indicator, keep the watch in a location that best maintains stable reception.

• Even under optimum reception conditions, it can take about 10

seconds for reception to stabilize.

• Note that weather, the time of day, surroundings, and other factors all

can affect reception.

Using Reference Altitude Values

To minimize the chance of reading error, you should update the reference altitude value before setting off on a trek or any other activity where you plan to take altitude readings. During a trek, keep checking the readings produced by the watch against altitude information provided by markers and other information, and update the reference altitude value as required.

• Reading error can be caused by changes in barometric pressure, atmospheric conditions, and

elevation.

• Before performing the procedure below, look up the altitude of your current location on a map, the

Internet, etc.

Auto Save Values

The watch automatically keeps track of the four types of values below, and updates them as required along with the time and date of the reading. High Altitude (MAX) Low Altitude (MIN) Cumulative Ascent (ASC) Cumulative Descent (DSC)

• For detailed information about each value, see page E-47.

• For information about viewing these values, see “Viewing Memory Records” (page E-70).

• These values are checked and updated automatically by the watch as altitude auto measurements are

taken. You can change the auto save interval, if you want (page E-37).

• Auto save is performed only while the watch is in the Altimeter Mode.

Types of Altitude Data

Your watch stores two types of altitude data: altitude records and historical altitude values.

Manually Saved Records

Each altitude reading you take manually is stored along with the date and time of the reading as an “altitude record”. You can later recall an altitude record to view it.

Important!

• The watch has memory for storage of up to 40 records of various types. If you perform an operation

that creates a new record while there are already 40 records in memory, the oldest record is deleted automatically to make room for the new one (page E-70). Note that altitude differential graph and altitude tendency graph information is not stored as part of an altitude record.

Operation Guide 3410

How does the altimeter work?

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

E-48

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-44).

• 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.

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.

• Do not rely upon this watch for altitude reading 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.

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.

E-49

Precautions Concerning Simultaneous Altitude and Temperature Readings

For the more accurate altitude readings, leaving the watch on your wrist is recommended in order to maintain the watch at a constant temperature.

• When taking temperature readings, keep the watch at as stable a temperature as possible. Changes in

temperature can affect temperature readings. See product speciﬁ cations (page E-100) for sensor accuracy information.

E-50

Taking Direction Readings

You can use the watch to take direction readings to determine a direction (north, south, east, west) or to ﬁ nd out your bearing to a destination.

• For information about what you can do to ensure direction readings are accurate, see “Magnetic

Declination Correction” (page E-58) and “Digital Compass Precautions” (page E-59).

Correcting Direction Reading Error (2-point Calibration)

Use 2-point calibration to correct for measurement error due to local magnetism or other causes.

Important!

• Keep the watch level during the calibration process.

• Keep the watch away from electrical household appliances and ofﬁ ce equipment, cellphones, and

other sources of strong magnetism during calibration. Such items can make proper calibration impossible.

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°.

Using Bearing Records

You can use the procedure in this section to create a bearing record of your current bearing reading, along with the date and time of the reading. You can later recall a record to view it.

Important!

• The watch has memory for storage of up to 40 records of various types. If you perform an operation

that creates a new record while there are already 40 records in memory, the oldest record is deleted automatically to make room for the new one (page E-70).

Digital Compass Precautions Magnetic North and True North

True north

Magnetic north

Earth

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.

The northerly direction can be expressed either as magnetic north or true north, which are different from each other. Also, it is important to keep in mind that magnetic north moves over time.

• Magnetic north is the north that is indicated by the needle of a compass.

• True north, which is the location of the North Pole of the Earth’s axis, is the

north that is normally indicated on maps.

• The difference between magnetic north and true north is called the

“declination”. The closer you get to the North Pole, the greater the declination angle.

E-59

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 2-point calibration” (page E-52).

Reading Barometric Pressure Differential Pointer

Pressure differential is indicated in the range of ±10 hPa, in 1-hPa units.

• The nearby illustration, for example, shows

what the pointer would indicate when the calculated pressure differential is approximately – 5 hPa (approximately – 0.15 inHg).

• Barometric pressure is calculated and

displayed using hPa as the standard. The barometric pressure differential also can be read in inHg units as shown in the illustration

(1 hPa

0.03 inHg).

E-64

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.

Enabling or Disabling Display of the Barometric Pressure Change Indicator

You can enable or disable display of the barometric pressure change indicator as desired. When display of the indicator is enabled, the watch will take a barometric pressure reading every two minutes, regardless of the mode it is in.

Barometric Pressure Change Indications

Your watch analyzes past barometric pressure readings and uses a barometric pressure change indicator to inform you about changes in pressure.The watch will beep to let you know when a signiﬁ cant change in barometric pressure is detected. This means you could start taking barometric pressure readings after reaching a lodge or camp area, and then check the watch the next morning for changes in pressure, and plan you day’s activities accordingly. Note that you can enable or disable display of the barometric pressure change indicator as desired.

Reading the Barometric Pressure Change Indicator

Indicator Meaning

Sudden fall in pressure.

Sudden rise in pressure.

Sustained rise in pressure, changing to a fall.

Using Barometric Pressure and Temperature Records

You can use the procedure in this section to create a barometric pressure and temperature record of your current readings, along with the date and time of the reading. You can later recall a record to view it.

Important!

• The watch has memory for storage of up to 40 records of various types. If you perform an operation

that creates a new record while there are already 40 records in memory, the oldest record is deleted automatically to make room for the new one (page E-70).

1. While barometric pressure and temperature readings are in progress, hold down C for at least two

seconds.

• REC and Hold will appear on th e display ﬁ rst, a nd then Hold will disa ppear. Releas e C after

Hold disappears.

• The watch will cre ate a record of the c urrent barom etric pressu re and temperat ure, along wit h

the date and tim e, and then retu rn automatic ally to the baro metric pres sure/temp erature readin g screen.

2. To view a record, enter the Data Recall Mode (page E-26) and use the A and C buttons to scroll. See “Viewing Memory Records” (page E-70) for more information.

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.

E-67

• 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.

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.

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. Because of this, there may be

some error in the readings produced by the watch.

• Temperature reading are affected by your body temperature, direct sunlight, and moisture. To achieve

a more accurate temperature reading, 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 surrounding temperature.

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 LED 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-88), 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.

If you are using the watch in an area where time calibration signal reception is possible, see “To conﬁ gure Home City and summer time settings” (page E-31). If you are using in the watch in an area where time calibration signal reception is not possible, you may need to change your Home City’s standard time/daylight saving time (DST) setting manually. Use the procedure under “To change the current time and date settings manually” (page E-33) to change the standard time/daylight saving time (DST) setting.

Correct altitude readings are not possible.

■

Relative altitude is calculated based on changes in barometric pressure readings by the pressure sensor. To minimize the chance of reading error due to changes in barometric pressure, you should update the reference altitude value before setting off on a trek or any other activity where you plan to take altitude readings. For more information, see “To specify a reference altitude value” (page E-44).

What causes incorrect direction readings?

■

• Incorrect 2-point calibration. Perform 2-point calibration (page E-52).

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

beam, overhead wires, etc., or an attempt to take direction readings 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.

as the Home City. You need to adjust the current time manually when any other city is selected as the Home City.

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

■

Possible Cause Remedy Page

• You are wearing or moving the

watch, or performing a button operation during the signal receive operation.

• The watch is in an area with

poor reception conditions.

You are in an area where signal reception is not possible for some reason.

The calibration signal is not being transmitted for some reason.

The current time setting changes after I set it manually.

■

You may have the watch conﬁ gured for auto receive of the time calibration signal (page E-18), which will cause the time to be adjusted automatically according to your currently selected Home City. If this results in the wrong time setting, check your Home City setting and correct it, if necessary (page E-31).

E-98

Keep the watch in an area where reception conditions are good while the signal receive operation is performed.

See “Approximate Reception Ranges”. E-16

• Check the website of the organization that maintains the time

calibration signal in your area for information about its down times.

• Try again later.

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.

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.

The barometric pressure differential pointer does not appear on the display when I enter the

■

Barometer/Thermometer Mode.

• This could indicate sensor error. Try pressing B again.

• The barometric pressure differential pointer is not displayed when the displayed current barometric

value is outside of the allowable measurement range (260 to 1,100 hPa).

World Time Mode

The time for my World Time City is off in the World Time Mode.

■

This could be due to incorrect switching between standard time and daylight saving time. See “To specify standard time or daylight saving time (DST) for a city” (page E-76) for more information.

Charging

The watch does not resume operation after I expose it to light.

■

This can happen after the power level drops to Level 5 (page E-11). Continue exposing the watch to light until the battery power indicator shows H or M.

E-97

The current time setting is off by one hour.

■

Possible Cause Remedy Page

Signal reception on a day for switching between standard time/daylight saving time (DST) may have failed for some reason.

Auto receive is not performed or you cannot perform manual receive.

■

Possible Cause Remedy Page

The watch is not in the Timekeeping Mode or World Time Mode.

Your Home City setting is wrong. Check your Home City setting and correct it, if necessary. E-31

There is not enough power for signal reception.

Signal reception is being performed successfully, but the time and/or day is wrong.

■

Possible Cause Remedy Page

Your Home City setting is wrong. Check your Home City setting and correct it, if necessary. E-31

The DST setting may be incorrect.

Perform the operation under “To get ready for a receive operation”. The time setting will be adjusted automatically as soon as signal reception is successful.

If you are unable to receive the time calibration signal, change the standard time/daylight saving time (DST) setting manually.

Auto receive is performed only while the watch is in the Timekeeping Mode or World Time Mode. Switch to either of these two modes.

Expose the watch to light to charge it. E-10
