Battery power indicator

The watch is charged sufficiently. For details about charging, see “Charging the Watch”.

Go to step 2.

2. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To conﬁ gure Home City settings” to conﬁ gure your Home City and daylight saving time settings.

Important!

World Time Mode and Sunrise/Sunset Mode data depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you conﬁ gure these settings correctly.

3. Set the current time.

See “Conﬁ guring Current Time and Date Settings”.

The watch is now ready for use.

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.

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

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

Power Levels

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

• 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.

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 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 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.

• 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” 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. There are three different calibration methods available: magnetic declination correction, bidirectional calibration, and northerly calibration.

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°.

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.

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.

To perform bidirectional calibration

• - - - is shown on th e display while c alibration is b eing perfo rmed. Whe n calibration i s successf ul,

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.

In the Digital Compass Mode, hold down E until the current magnetic declination settings start to ﬂ ash on the display. This is the setting screen.

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.

• Finding the bearing to an objective

• Determining the direction angle to an objective on a map and heading in that direction

To set a map and ﬁ nd your current location

1. With the watch on your wrist, position it so the face is horizontal.

2. While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

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”.

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.

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.

Altimeter

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.

• 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.

Specifying a Reference Altitude Value

The altitude readings produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude value whenever one is available during your climb. After you specify a reference altitude value, the watch adjusts its air-pressure-to-altitude conversion calculation accordingly.

To specify a reference altitude value

Types of Altitude Data

The watch can maintain two types of altitude data in its memory: manual measurement records, and auto save values (minimum, maximum, vertical ascent, vertical descent).

• Use the Data Recall Mode to view data stored in memory. See “Viewing Altitude Records” for details.

Manual Measurement Records

Any time you perform the procedure below in the Altimeter Mode, the watch will create and store a record with the currently displayed altitude reading, along with the date and time the reading was taken. There is enough memory to store up to 25 manual measurement records, which are numbered from

REC25

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

• For details about clearing altitude data, see “To clear the contents of a speciﬁ c memory area”.

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.

• Note that the following conditions will prevent you from obtaining accurate readings:

When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact

There are two standard methods of expressing altitude: Absolute altitude and relative altitude. Absolute altitude expresses an absolute height above sea level. Relative altitude expresses the difference between the height of two different places.

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 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.

Viewing Altitude Records

Use the Data Recall Mode to view manually saved altitude readings and automatically saved high altitude, low altitude, total ascent, and total descent values. Altitude data records are created and saved in the Altimeter Mode.

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.

Note

• This watch features a “Full Auto EL Light”, so the auto light switch operates only when available light is

below a certain level. It does not illuminate the display under bright light.

• The auto light switch is always disabled, regardless of its on/off setting, when any one of the following

conditions exists.

Illumination Precautions

• Frequent display illumination can run down the battery quickly and require charging.

The following guidelines give an idea of the charging time required to recover from a single illumination operation.

Approximately ﬁ ve minutes exposure to bright sunlight coming in through a window Approximately 50 minutes exposure to indoor ﬂ uorescent lighting

• 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 turns off after the preset illumination duration, 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.

Try performing calibration again, taking care to ensure that the watch is not moved. If this does not solve the problem, the problem may be due to some nearby source of terrestrial magnetism. 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.

• 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.

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.
