Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

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 be sure to use a second compass to confirm 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.

Keep the watch exposed to bright light

Warning!

The electricity generated by the solar cell of the watch is stored by a built-in battery. Leaving or using the watch where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

• When you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.

• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will result in some watch functions being disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light. Battery discharges in the dark.

Operation Guide 3135 3206

• 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 finished.

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

Meaning

• See “Digital Compass Precautions” for other important information about taking direction readings.

Digital Compass Precautions

This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that nor th 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 also should 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 also are 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 be sure to 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 one of the calibration procedures under “Calibrating the Bearing Sensor”.

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 degree units only, so you may need to round off the value specified 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 direction 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!

• If you want to perform both bidirectional and northerly calibration, be sure to perform bidirectional calibration first, and then perform northerly calibration. This is necessary because bidirectional calibration cancels any existing northerly calibration setting.

• 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.

1. In the Digital Compass Mode, hold down E

Magnetic declination angle direction

Magnetic declination angle value

E: When magnetic north is to the east (east declination) W: When magnetic north is to the west (west declination)

• You can turn off (OFF) magnetic declination correction (which effectively

makes the magnetic declination angle: 0°) by pressing A and C at the same time.

• The illustration above, for example, shows the value you should input and the direction setting you should select when the map shows a magnetic declination of 1° West.

3. When the setting is the way you want, press E to exit the setting screen.

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.

• Make sure that you 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 field, for example, calibrate in an open field.

Using the Digital Compass While Mountain Climbing or Hiking

This section describes three real-life situations where you could use the watch’s built-in digital compass.

• To set a map and find 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.

• To find the bearing to an objective

• To determine the direction angle to an objective on a map and head in that

direction

• If you find it difficult to perform the above step while keeping everything aligned, first move into the correct position (12 o’clock position of the watch pointed at the objective) without worrying about the orientation of the map. Next, perform step 1 again to set the map.

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

2. In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading.

• The reading will appear on the display after

about two seconds.

3. Rotate the map without moving the watch so the northerly direction indicated on the map matches north as indicated by the watch.

• If the watch is configured to indicate

magnetic north, align the map’s magnetic north with the watch indication. If the watch has been configured with a declination to correct to true north, align the map’s true north with the watch indication.

• This will position the map in accordance

with your current location.

4. Determine your location as you check the geographic contours around you.

1. Take a compass reading and then 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 and find your current

location” for information about how to perform the above step.

2. Set the map so the direction you want to travel on the map is pointed straight in front of you.

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

4. In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading.

• The reading will appear on the display after

about two seconds.

5. Still holding the map in front of you, turn your body until north as indicated by the watch and the northerly direction on the map are aligned.

Note

• The following procedure is possible only with a

watch that has a rotary bezel.

1. Take a compass reading and then 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 and find your current

location” for information about how to perform the 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 map aligned with the readings being produced by the watch.

12 o’clock position

Direction angle of current reading

4. Rotate the bezel so the “N” (North) indicator on the bezel is aligned with the north indicator produced by the reading in step 3.

5. To advance to your objective proceed in the direction that 12 o’clock is pointing.

Note

• When mountain climbing or hiking, conditions or geographic contours may

make it impossible for you to advance in a straight line. If this happens, return to step 1 and save a new direction to the objective.

3. In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading.

• The compass reading information (angle

value, direction indicator, and four pointers based on the 12 o’clock position of the watch) will appear on the display after about two seconds.

North pointer

• The compass reading information will

remain on the display for only about 20 seconds after you press C. After that it will disappear. If you want to re-display the compass reading information, press C again to take another reading.

Barometer/Thermometer

This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.

• You can calibrate the pressure sensor and the temperature sensor if you suspect that readings are incorrect.

To take barometric pressure and temperature readings

Barometric pressure graph

Temperature

• The displayed barometric pressure value changes to a measured barometric pressure falls outside the range of 260 hPa to 1100 hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will reappear as soon as the measured barometric pressure is within the allowable range.

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

• The displayed temperature value changes to

measured temperature falls outside the 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.

• In some areas, barometric pressure is expressed in millibars (mb) instead of hectopascals (hPa). It really makes no difference, because 1hPa = 1mb.

• You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “To select the temperature, barometric pressure, and altitude units”.

• See “Barometer and Thermometer Precautions” for important precautions.

Barometric Pressure Graph

Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. This watch takes barometric pressure measurements automatically every two hours (at the top of each even-numbered hour), regardless of its current mode. Measurement results are used to produce barometric pressure graph and barometric pressure differential pointer readings. The barometric pressure graph shows readings of previous measurements for up to 20 hours. The horizontal axis of the graph represents time, with each dot standing for two hours. The rightmost dot represents the most recent reading. The vertical axis of the graph represents barometric pressure, with each dot standing for the relative difference between its reading and that of the dots next to it. Each dot represents 1hPa. The following shows how to interpret the data that appears on the barometric pressure graph.

Pressure differential pointer

A rising graph generally means improving weather.

A falling graph generally means deteriorating weather.

Pressing B in the Timekeeping Mode or in any of other sensor modes enters the Barometer/ Thermometer Mode and starts barometric pressure and temperature measurements automatically .

• It can take up to four or five seconds for the barometric pressure reading to appear after you enter the Barometer/Thermometer Mode.

Note that if there are sudden changes in barometric pressure or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize. The following conditions cause the barometric pressure measurement to be skipped, with the corresponding point on the barometric pressure graph being left blank.

• Barometric reading that is out of range (260 hPa/mb to 1,100 hPa/mb or

7.65 inHg to 32.45 inHg)

• Sensor malfunction

Barometric Pressure Differential Pointer

This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph, and the current barometric pressure value displayed in the Barometer/ Thermometer Mode.

• Pressure differential is indicated in the range of ±5 hPa, in 1-hPa units.

• 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).

• 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.

Pressure differential examples in the illustration are indicated in 3 hPa/0.1 inHg steps.

About Barometric and Temperature Measurements

• Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, barometric pressure and temperature measurements are taken every five seconds.

• You also can perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer/Thermometer Mode.

Not visible on the display.

Altimeter

The watch’s altimeter uses a pressure sensor to detect current air pressure, which is then used to estimate the current altitude based on ISA (International Standard Atmosphere) preset values. You also can specify a reference altitude, which the watch will use to calculate your current altitude based on the value you specify. Altimeter functions also include storage of measurement data in memory.

Important!

• 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 also is affected by temperature. When taking altitude measurements, make sure the watch is not subjected to temperature changes.

• To avoid the effect of sudden temperature changes during measurement, keep the watch on your wrist in direct contact with your skin.

• 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 flight crew.

How the Altimeter Measures Altitude

The altimeter can measure altitude based on its own preset values, or a reference altitude specified by you.

When you measure altitude based on preset values

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

When you measure altitude using a reference altitude specified by you

After you specify a reference altitude, the watch uses that value to convert the current measured barometric pressure value to altitude.

• When mountain climbing, you can set the reference 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.

Displaying Your Current Altitude

You can use the procedure described in this section to display your current altitude. If you leave the watch in the Altimeter Mode, it will update the displayed altitude value regularly, and indicate reading-to-reading changes in the altitude graph at the top of the display.

Important!

• The procedure in this section simply displays values indicating your current altitude, without storing them in watch memory. For information about recording altitude readings in watch memory, see “Saving Altitude Data”.

Current time

• Readings are taken at five-second intervals for the first three minutes after you enter the Altimeter Mode. After that, readings are taken at twominute intervals.

• If you want to restart the altitude measurement operation at any point, press A.

3. To stop the altitude measurement operation, press D to exit the Altimeter

Mode.

Notes

• Normally, displayed altitude values are based on the watch’s preset conversion values. You also can specify a reference altitude, if you want. See “Specifying a Reference Altitude”.

• Altitude is displayed in units of 5 meters (20 feet).

• The measurement range for altitude is –700 to 10,000 meters (–2,300 to

32,800 feet).

• The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions.

• The displayed altitude value changes to measured altitude falls outside the measurement range. The altitude value will be displayed again as soon as the measured altitude is within the allowable range.

• You can change the measurement unit for displayed altitude values to either meters (m) or feet (ft). See “To select the temperature, barometric pressure, and altitude units”.

Saving Altitude Data

The watch automatically keeps track of the high altitude achieved to date. You also can save altitude readings with the touch of a button.

• You can recall and view altitude data using the Data Recall Mode. For details, see “Recalling Altitude Data”.

Automatic High Altitude Record

Whenever an altitude measurement in the Altimeter Mode is greater than the currently stored high altitude value, the watch will replace the old value with the new measurement automatically, along with the reading date and time. This feature is always enabled and cannot be turned off.

• If the current reading is the same as the existing high altitude value, the older value will be retained.

Saving an Altitude Reading

Perform the following procedure whenever you want to save an altitude reading.

1. Press A in the Timekeeping Mode or in any

of the other sensor modes to enter the Altimeter Mode.

• The watch will start altitude measurement automatically, and display the result.

Specifying a Reference Altitude

After you specify a reference altitude, the watch adjusts its air-pressure-toaltitude conversion calculation accordingly. The altitude measurements 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 whenever one is available during your climb.

To set a reference altitude

• Pressing A and C at the same time returns to OFF (no reference

altitude), so the watch performs air pressure to altitude conversions based on preset data only.

3. Press E to exit the setting screen.

Configuring Countdown Timer Settings

The following are the settings you should configure before actually using the countdown timer.

Countdown start time and reset time Progress beeper (on/off)

• See “To configure countdown timer settings” for information about setting up the timer.

• For details about the progress beeper, see “Progress Beeper”.

Reset Time

You can set a “reset time”, which is a kind of alternate countdown start time you can recall with the press of a button any time a countdown operation is in progress.

Countdown Timer Beeper Operations

The watch beeps at various times during a countdown so you can keep informed about the countdown status without looking at the display. The following describes the types of beeper operations the watch performs during a countdown.

Current time

The countdown timer can be set within a range of one minute to 60 minutes. An alarm sounds when the timer reaches zero. The press of a button will start the countdown timer from the currently set start time, and a progress beeper sounds to keep you informed of the current status of the countdown. These features make it possible to use the watch for yacht racing.

• All of the operations in this section are performed in the Countdown Timer Mode, which you enter by pressing D.

Countdown End Beeper

The watch beeps each second of the final 10 seconds before a countdown reaches zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal when the countdown reaches zero.

Progress Beeper

The progress beeper actually includes two beepers: a reset time beeper and a reset period beeper.

• Note that the reset time beeper and reset period beeper operate only while the progress beeper is turned on. For more infor mation, see “To turn the progress beeper on and off”.

Reset Time Beeper

The reset time beeper is similar to the countdown end beeper. The watch beeps each second of the final 10 seconds before the countdown reaches the reset time.

Reset Period Beeper

The reset period is in the portion of the countdown between the reset time and zero. While timing is the reset period, the watch will beep four times at the top of each minute and 10 seconds before the end of the countdown.

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.

Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.

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.

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 specified by you.

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” to change the indicator.

Tide Graph

The Tide Graph graphically represents the current tide condition using one of three patterns that represent spring tide, intermediate tide, and neap tide, as shown below.

Tide Name Graph Description

Spring Tide

Intermediate Tide

Neap Tide

•

The Tide Graph flashes as shown below to indicate the tide range.

•

The segments on either end of the Tide Graph flash during high tide.

Lunitidal Interval

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”.

Auto Return Features

• The watch returns to the Timekeeping Mode automatically if you do not perform any button operation for two or three minutes in the Tide/Moon Data, Alarm, Data Recall, Digital Compass, or Barometer/Thermometer Mode.

• If you do not perform any button operation while in the Altimeter Mode, the watch returns to the Timekeeping Mode automatically after nine or 10 hours.

• If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.

Initial Screens

When you enter the World Time or Alarm Mode, the data you were viewing when you last exited the mode appears first.

Scrolling

The A and C buttons are used on the setting screen to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.

Sensor Malfunction Indicator

(Function Sleep)

• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.

• The watch will not enter the sleep state while the digital time is between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when the digital time reaches 6:00 AM, however, it will remain in the sleep state.

• The watch will not enter the sleep state while it is in the Digital Compass, Barometer/Thermometer, Altimeter, Countdown Timer, or Stopwatch Mode. When the watch is left in any mode besides the Countdown Timer and Stopwatch Mode, it will return to the Timekeeping Mode automatically after a specific amount of time. Then if left in the dark for the elapsed time indicated in the table above, the watch will enter the sleep state.

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.

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

• The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

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.

• The watch may emit an audible sound whenever the display is illuminated.

This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.

• Frequent use of illumination runs down the battery.

Auto light switch precautions

• The auto light switch is turned off automatically whenever battery power is at Level 4.

• 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.

More than 15 degrees too high

• 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.

• Under certain conditions, illumination does not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction.

• 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.

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 official 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.

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.

• 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 in about one second, even if you keep the watch pointed towards your face.

To calibrate the pressure sensor and the temperature sensor
