History Graph and Barometric PressureHistory graph

Barometric pressure

• It can take up to four or five seconds for the barometric pressure reading to

appear after you enter the Barometer/Thermometer Mode.

• Barometric pressure is displayed in units of 1hPa.

• The displayed barometric pressure value changes toxxxx hPa if a

measured barometric pressure falls outside the range of 260 hPa to 1100 hPa. The barometric pressure value will be displayed again as soon as the measured barometric pressure is within the allowable range.

• Temperature is displayed in units of 0.1

• The displayed temperature value changes to xx. x

temperature falls outside the range of –10.0 value will be displayed again as soon as the measured temperature is within the allowable range.

• Some countries refer to the barometric pressure unit hecto-pascal (hPa) as

millibars (mb). It really makes no difference, because 1hPa = 1mb.

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

Barometric Pressure History Graph

Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. The barometric pressure history graph contains points that show you the changes in barometric pressure readings taken by the watch for up to the last 18 hours. The time line along the bottom of the graph runs from left to right, which means that the rightmost point on the graph is the latest reading. The relative positions of the points on the graph indicate whether barometric pressure is rising, falling, or holding relatively steady.

Relatively steady (within ±

• No point is plotted on the graph whenever a measurement operation fails

due to sensor malfunction, low battery power, or any other reason.

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 off 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

A built-in altimeter uses a pressure sensor to detect the current air pressure, which is then used to estimate the current altitude. The watch is preprogrammed with ISA (International Standard Atmosphere) preset values, which are used to convert air pressure readings to altitude values. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value. Memory is also provided for the storage of altimeter data.

Important!

• This watch estimates altitude based on air pressure. This means that

altitude readings for the same location may vary if air pressure changes.

• This watch employs a semiconductor pressure sensor, which is affected by

temperature changes. Make sure that the watch is not being exposed to temperature changes while you are taking altitude measurements.

• To avoid the effect of sudden temperature changes on measurement, wear

the watch so it is in direct contact with your wrist during measurement.

• Do not rely upon this watch for altitude measurements or perform button

operations while engaging in sports where there are sudden altitude changes, while sky diving, hang gliding, or paragliding, or while riding a gyrocopter, glider, or any other aircraft.

• 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 flight crew.

How the Altimeter Works

With the Preset Values (No Reference Altitude)

• The watch measures the air pressure at your current location and uses the

built-in ISA values to convert it to the equivalent altitude.

With a Reference Altitude

• If you set a reference altitude, the watch

uses that value when calculating altitude based on air pressure.

• To determine the height of a tall building,

set the reference altitude to 0 on the ground floor. Note, however , that you may not be able to get a good reading if the building is pressurized or air-conditioned.

• When mountain climbing, you can set the

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

To take an altitude reading

• It can take up to four or five seconds for the

altitude reading to appear after you enter the Altimeter Mode.

• The Altimeter Mode screen also displays the

current temperature. See “Barometer/ Thermometer” for more information.

• During the first three minutes after entering the

reference altitude value set or because of certain atmospheric conditions.

• The displayed altitude value changes to

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

Setting a Reference Altitude

After you set a reference altitude, the watch adjusts its air-pressure-to-altitude 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.

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on for about two seconds, whenever you position your wrist as described below in any mode. Note that 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 turn on the backlight under bright light.

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

•

Wear the watch on the outside of your left wrist.

The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. The watch’s auto light switch automatically turns on the backlight when you angle the watch towards your face.

•

The auto light switch must be turned on

(indicated by the auto light switch on indicator) for it to operate.

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. The following describes what you should do to give priority to either altitude or temperature.

• 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 momentarily affect pressure sensor readings.

Question: How does the barometer work?

Answer: Barometric pressure indicates changes in the atmosphere, and by

monitoring these changes you can predict the weather with reasonable accuracy. Rising atmospheric pressure indicates good weather, while falling pressure indicates deteriorating weather conditions. The barometric pressures that you see in the newspaper and on the TV weather report are measurements corrected to values measured at 0 m sea level.

• 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 rechargeable battery power to run down. Be sure that the watch is normally exposed to bright light whenever possible.

• This watch employs a solar cell that converts light into electricity, which

charges a built-in rechargeable battery. Normally, the rechargeable battery should not need replacement, but after very long use over a number of years, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the rechargeable battery to a full charge, contact your dealer or CASIO distributor about having the rechargeable battery replaced.

• The rechargeable battery should be replaced with a CASIO-specified

CTL1616 battery only. Other rechargeable batteries can cause damage to the watch.

• 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 4 and when you have the battery replaced.

• 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 keep the rechargeable battery from going dead.

Battery Power Indicator

The battery power indicator on the display shows you the current status of the rechargeable battery’s power.

Battery power indicator

This watch is equipped with a solar cell and a rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown nearby shows how you should position the watch for charging.

Example: Orient the watch so its face is pointing

at a light source.

• Note that charging efficiency

drops when any part of the solar cell is blocked by clothing, etc.

• The illustration shows how to

position a watch with a resin band.

• The flashing CHARGE indicator at Level 3 tells you that battery power is

very low, and that exposure to bright light for charging is required as soon as possible.

• At Level 4, all functions are disabled and settings return to their initial

factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 2 (indicated by the M indicator) from Level 4. Y ou will not be able to set any of the other settings until the battery reaches Level 1 (indicated by the H indicator) after dropping to Level 4.

• Display indicators reappear as soon as the battery is charged from Level 4

to Level 3.

• Leaving the watch in direct sunlight or some other very strong light source

can cause the battery power indicator to temporarily show a reading that is higher than the actual battery level. The correct battery power indicator should appear after a few minutes.

• Even if battery power is at Level 1 or Level 2, the Digital Compass Mode,

Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently . This condition is indicated on the display as shown in the table below. Sensor operation should resume when battery voltage returns to normal levels.

• The last measured data may still remain on the display if you enter one of

the sensor modes while RECOV is on the display.

• If RECOV appears frequently , it probably means that remaining battery

power is low. Leave the watch in bright light to allow it to charge.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that 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.

Warning! Leaving the watch in bright light to charge its rechargeable battery 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

Backlight Precautions

• The electro-luminescent panel that provides illumination loses power after

very long use.

• The illumination provided by the backlight may be hard to see when viewed

under direct sunlight.

• The backlight automatically turns off 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 the backlight 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.

More than 15 degrees too high

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

auto light switch. If the backlight does not light, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you 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, the backlight may not light until about one second

after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

• Y ou 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.

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. Y o u 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 ferro-

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

• Movement of the analog hands during digital compass operation in an area

where terrestrial magnetism is weak can cause the pointer position and angle value to be slightly off.

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

Whenever you suspect that direction readings produced by the watch are wrong, you should calibrate it. Y ou can use either one of two calibration procedures: 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). You could use this calibration procedure, for example, to set the watch to indicate true north instead of magnetic north.

Important!

• If you want to perform both bidirectional and northerly calibration, be sure

• The more correctly you perform bidirectional calibration, the better the

Precautions about bidirectional calibration

Calibrating the Temperature Sensor

The temperature sensor of this watch is calibrated at the factory before shipment, and further adjustment is normally not required. If you notice serious errors in the temperature readings 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 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
