Important!

• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure

readings produced by its pressure sensor. This means that readings taken at different times at the same location may produce different altitude values due to changes in barometric pressure. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

• When using the watch’s altimeter while mountain climbing, be sure to perform regular calibration in

accordance with the local altitude (elevation) indications. For more information, see “To specify a reference altitude value” (page E-70).

• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other

activities, be sure always to take along another compass to conﬁ by the digital compass of this watch are different from those of the other compass, perform ﬁ gure 8 calibration or 3-point calibration of the digital compass to ensure more accurate readings.

Important!

• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or

totally white, depending on the watch model). The appearance of the LCD should become normal again when the watch returns to a lower temperature.

• Enable the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright

light when storing it for long periods. This helps to ensure that power does not run down.

• Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is

blocked from exposure to light can cause power to run down. Expose the watch to bright light whenever possible.

Power Levels

Hold down B for at least two seconds to enter the Timekeeping Mode. 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 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 conditions below for long periods.

• 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.

A dark environment while battery power is at Level 4 will cause the level to drop to Level 5. Expose the

watch to bright light whenever possible.

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-36) for more information. This section explains how the watch updates its time settings automatically 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)

HKG, BJS Shangqiu City (China)

TPE, SEL, TYO Fukushima (Japan), Fukuoka/Saga (Japan)

• 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.

Barometric Pressure Change Indications

Your watch analyzes past barometric pressure readings and uses a barometric pressure change indication to inform you about changes in pressure. If the watch detects a signiﬁ cant change in barometric pressure, it will beep, a ﬂ ashing arrow that indicates the direction of the pressure change will be displayed, and the small hand will point to the arrow mark. 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. You will then be able to plan your day’s activities accordingly. Note that you can enable or disable display of the barometric pressure change indicator as desired. Barometric pressure change is indicated in the Barometer Mode, while the Barometric Pressure Graph is displayed in the Timekeeping Mode (page E-33).

• If the digital display contents start to ﬂ ash after you perform a reading operation, it means that

abnormal magnetism has been detected. Move away from any potential source of strong magnetism and try taking a reading again. If the problem occurs when you try again, continue to keep away from the source of strong magnetism, perform ﬁ reading again. For more information, refer to “To perform ﬁ gure 8 calibration” (page E-58), “To perform 3-point calibration” (page E-60) and “Location” (page E-65).

Digital Compass Readings

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

each second for up to 60 seconds. After that, the reading operation will stop automatically.

• 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.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off.

Figure 8 Calibration, 3-point Calibration

•

You should perform calibration whenever direction readings produced by the watch do not match those of another reliable compass, and before setting off on a trek or climb. Leave the watch on your wrist when performing ﬁ wrist. Both calibration methods calibrate the bearing sensor. You can use either method for calibration.

Important!

• If the readings produced by the digital compass of this watch are different from those of the other

compass, perform ﬁ accurate readings. Accurate measurements and/or calibration will not be possible in an area exposed to strong magnetic force and indoors (especially inside reinforced concrete structure). In this case, moving outdoors, away from the source of magnetism for measurement and calibration is recommended.

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 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°.

• The watch has memory that is shared for storage of up to 40 records, including bearing data. Note that

recording new data when there are 40 data records in memory causes the oldest record to be deleted automatically to make room for the new record. See “Viewing Recorded Data” (page E-87).

To record the bearing to an objective

While taking a direction reading, hold down A for at least two seconds.

• This records t he bearing along wit h the current date and time.

• The watch will return to the Bearing Mode screen automatically after recording is complete.

Digital Compass Precautions Magnetic North and True North

True north

Magnetic north

Earth

E-64

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.

Using the Altimeter Mode

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor.

• The displayed altitude reading is a relative altitude that is calculated based on measurement of

changes in barometric pressure by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at different times at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you perform regular calibration in accordance with the local altitude (elevation) indications.

Important!

• See “To specify a reference altitude value” (page E-70) and “Altimeter Precautions” (page E-76) for information

about how to minimize differences between readings produced by the watch and values provided by local altitude (elevation) indications.

Getting Ready

Before actually taking an altitude reading you need to select an altitude reading interval.

Selecting the Altitude Reading Interval

You can select either of the two altitude measurement intervals below.

0'05

: Readings at one-second intervals for the ﬁ rst three minutes, and then every ﬁ ve seconds for

approximately the next hour

2'00

: Readings at one-second intervals for the ﬁ rst three minutes, and then every two minutes for

approximately the next 12 hours

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

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

• Accurate direction readings are impossible while in a train, boat, air plane, 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.), concentrations of metal (metal doors, lockers, 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

gure 8 calibration” (page E-58) or “To perform 3-point calibration” (page E-60).

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.

To record altitude

In the Altimeter Mode, hold A for at least two seconds.

• This records the altitude along with the current date and time.

• The watch will return to the Altimeter Mode screen automatically after the save operation is complete.

Advanced Altimeter Mode Operations

Use the information in this section to obtain more accurate altimeter readings, especially while mountain climbing or trekking.

Note

• To toggle between the altitude differential and current time seconds count, press C.

Using an Altitude Differential Value

Altitude differential

If you specify a reference altitude, the second hand of the watch will indicate the difference between the current altitude and the reference altitude. The displayed altitude differential value is updated each time the watch obtains a new altitude reading value.

• Depending on the currently selected display range, the allowable

range for the altitude differential value is 100 meters to –100 meters (100 meters = 328 feet), or 1,000 meters to –1,000 meters (1,000 meters = 3,280 feet).

How does the altimeter work?

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

• Note that the conditions below 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, which expresses an absolute height above sea level, and relative altitude, which expresses the difference between the altitudes of two different places. This watch expresses altitudes as relative altitude.

4. While comparing the altitude differential you calculated using your map with the altitude differential indicated by the watch’s second hand, advance towards your destination.

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 use 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

E-76

ight crew.

Taking Temperature Readings

This watch uses a temperature sensor to measure temperature.

Temperature

• Temperature is displayed in units of 0.1°C (or 0.2°F).

• The displayed temperature value changes to

range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the measured temperature is within the allowable range.

Display Units

You can select Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “To specify altitude, depth, barometric pressure, and temperature units” (page E-43).

E-78

To take temperature readings

While in the Timekeeping Mode or a sensor mode, use A to cycle through the sensor modes until “Selecting a Mode” (page E-30).

• This enters the Temperature Mode and displays a temperature reading

after about one second.

• After a temperature reading operation is started, the watch will take

readings every ﬁ two minutes after that.

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

can affect readings.

E-77

Temperature Sensor Calibration

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

Important!

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

Carefully read the information below 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 temperature sensor

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

2. While in the Timekeeping Mode or a sensor mode, use A to cycle through the sensor modes until

3. Pull out the crown. This will cause the current temperature reading value to ﬂ ash on the digital display.

About the Auto Light Switch

Enabling 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 disabled 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.

E-112

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, disable 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 enabled can cause

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

E-114

• 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-111), 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.

More than 40°

Wear the watch on the outside of your wrist

Note

• This watch features a “Full Auto 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.

Relative altitude is calculated based on changes in barometric pressure measurement by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at different times at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, you need to be sure to perform regular calibration in accordance with the local altitude (elevation) indications.
