Static electricity or magnetic force can interfere with proper operation of the auto backlight function. If the auto backlight does not illuminate, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards 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 or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

Warning!

Never try to read your watch when mountain climbing or hiking in areas that are dark or in areas with poor footing. Doing so is dangerous and can result in serious personal injury.

Never try to read your watch when running where there is the danger of accidents, especially in locations where there might be vehicular or pedestrian traffic. Doing so is dangerous and can result in serious personal injury.

Never try to read your watch when riding on a bicycle or when operating a motorcycle or any other motor vehicle. Doing so is dangerous and can result in a traffic accident and serious personal injury.

When you are wearing the watch, make sure that its auto backlight function is turned off before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto backlight can create a distraction, which can result in a traffic accident and serious personal injury.

BAROMETER MODE

This watch uses a pressure sensor to measure barometric pressure. It can be adjusted to correct for measurement error.

Important !

The barometer that is built into this watch measures changes in barometric 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.

Example barometer applications

Before going mountain climbing, you can take readings to predict upcoming weather.

You can predict the weather for golf or other outdoor activities.

About barometric pressure measurements

The watch takes barometric pressure measurements every five seconds for the first two minutes after you enter the Barometer Mode. The Barometer Mode indicator 1 flashes on the display during these two minutes.

After the first two minutes, the Barometer Mode indicator 1 stops flashing, and the watch automatically takes measurements every two hours (starting from midnight).

The watch continues to take barometric pressure readings every two hours, even if you change to another mode. Measurement data can be viewed on the Timekeeping Mode screen on the barometric pressure graph.

Barometric pressure graph *1

*1 The barometric pressure graph shows the barometric pressure readings for the past 18 hours. The flashing point on the right of the display is the point of the last measurement.

*2 The displays show “– – – – hPa” (or inHg) if a measured value falls outside the range of 460 hPa/mb to 1100 hPa/mb (13.55 inHg to 32.45 inHg). The normal display will return as soon as the pressure returns with the allowable range.

2307/2335/2355/2357-3

Using the barometric pressure graph

Barometric pressure is affected by changes in weather and temperature. The following shows how to interpret the data that appears on the barometric pressure graph.

A rising graph generally means better weather.

A falling graph generally means deteriorating weather.

Note that if there are sudden changes in weather 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 pressure 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.

Calibrating the barometric pressure measurement

The sensor of this watch is calibrated at the factory before shipment, and further adjustment is normally not required. If noticeable error is found in the barometric pressure readings produced by the watch, you can adjust it to correct the error.

Important!

Incorrectly calibrating the barometric pressure measurement of this watch can result in incorrect readings. Compare the readings produced by the watch with those of another reliable, accurate barometer.

Calibrating the barometric pressure

1.Use Cto enter the Barometer Mode.

2.Hold down A until “OFF” or the current barometric pressure calibration value flashes on the display.

“OFF” appears when the factory setting is currently set as the current barometric pressure calibration value.

3.Each press of Dincreases the displayed barometric pressure by 1 hPa/mb, while pressing B decreases it. Holding down either button changes the value at high speed.

If inHg is currently selected as the unit of measurement, the above operations change the reading by 0.05 inHg.

Pressing Band Dat the same time returns to the “OFF” setting.

4.After calibrating the barometric pressure, press A to return to the Barometer Mode screen.

ALTIMETER MODE

A built-inaltimeter uses a pressure sensor to detect the current barometric pressure, which is then used to estimate the current altitude in accordance with ISA (International Standard Atmosphere) values for altitude and barometric pressure. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value.

Important !

This watch estimates altitude based on barometric pressure. This means that altitude readings for the same location may vary if barometric pressure changes.

Sudden changes in the weather make it impossible to produce accurate altitude readings.

This watch employs a semiconductor pressure sensor, which is affected by temperature changes. When taking altitude measurements, be sure to do so while ensuring that the watch is not exposed to temperature changes.

Do not use this watch while participating in sports where there are sudden altitude changes. Also, do not use this watch for applications that demand professional or industrial level precision. This watch should not be used while engaging in the following activities: skydiving, hang gliding, paragliding, gyrocopter riding, glider riding, etc.

Applications

When no reference altitude is preset:

The watch produces approximate altitude readings.

When a reference altitude is preset:

Before beginning the climb, set the reference altitude to 0 meter at the foot of the mountain. This makes it possible to determine the difference in altitude between the reference point and your destination.

To determine the height of a tall building, set the reference altitude to 0

meter on the ground floor. Note that you may not be able to get a good reading if the building is pressurized or airconditioned.

To determine the difference in altitude between your house and another location, set the reference altitude to 0 meter at your house, and then check the reading when you arrive at the other location.

When mountain climbing, you can input the altitude from a marker as your reference altitude, which will then let you know your altitude as your climb

proceeds. The following conditions will

400

prevent you from obtaining accurate readings:

When barometric pressure changes because of changes in the weather Extreme temperature changes

When the watch itself is subjected to strong impact

About altitude measurements

The watch measures altitude every five seconds for the first two minutes after you enter the Altimeter Mode. The Altimeter Mode indicator 1 flashes on the display during these two minutes.

After the first two minutes, the Altimeter Mode indicator 1 stops flashing, and the watch automatically takes measurements every two minutes (on even numbered minutes).

The display unit for Altimeter Mode measurements is 5 meters (20 feet), and the display range is 0 to 6,000 meters (0 to 19,680 feet).

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

Setting a reference altitude

After you set a reference altitude, the watch automatically calculates the difference between the current altitude and your preset value. The altitude measurements produced by this watch are subject to error caused by changes in barometric pressure. Because of this, we recommend that you set the reference altitude during your climb whenever one is available.

1.Use Cto enter the Altimeter Mode.

2.Hold down A until “OFF” or the current reference altitude value flashes on

the display.

“OFF” appears when the factory setting is currently set as the reference altitude value.

3.Each press of D increases the displayed altitude by 5 m, while pressing B decreases it. Holding down either button changes the value at high speed.

If you have selected feet as your unit of measurement, the above operations change the reading by 20 feet.

You can set the reference altitude within the range of –6,000meters to 6,000 meters(–19,680feet to 19,680 feet).

Pressing Band Dat the same time returns to the “OFF” setting.

4.After setting the reference altitude you want, press A to return to the Altimeter Mode screen.

THERMOMETER MODE

A built-intemperature sensor measures temperature and shows the measured value on the display. The thermometer can be calibrated to correct for errors.

Important!

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-ventilatedlocation 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 temperature of the surrounding air.

About temperature measurements

The watch takes temperature measurements every five seconds for the first two minutes after you enter the Thermometer Mode. The Thermometer Mode indicator 1 flashes on the display during these two minutes.

After the first two minutes, the Thermometer Mode indicator 1 stops flashing, and the watch automatically takes measurements every five minutes.

Understanding the temperature display

The display shows “– – .°C” (or°F) if a measured value falls outside the range of–10.0°Cto 60.0°C (14.0°F to 140.0°F). The normal display will return as soon as the temperature returns within the allowable range.

Err Display – Sensor Malfunction Warning

This message indicates malfunction of the watch’s pressure sensor circuitry. When sensor malfunction initially occurs, the watch stops taking measurements, the “Err” message appears, and a buzzer sounds for about three seconds.

If the sensor is malfunctioning when it comes time for a barometric pressure measurement to be taken, the barometric pressure value and altitude value appears as “– – – –”on the display and the corresponding point on the barometric pressure graph is left blank.

Whenever there is a sensor malfunction, be sure to take the watch to an authorized CASIO distributor or Service Center as soon as possible.

Alteration of and Graph – Temporary Low Power

Warning

Temporary low power is indicated on the display when the battery level temporarily drops below a certain level.

Sensors are disabled while the temporary low power warning is being indicated, but the light and tones are operational.

Very low temperature can cause the low power warning to appear even though battery power is not low. The low power warning should disappear when the watch is restored to normal temperature.

If the low power warning appears under normal temperature, replace the battery as soon as possible.

Alteration of and– Battery Usage Warning

The watch automatically monitors your use of certain high battery drain functions. The battery usage warning display appears whenever the watch determines that your use of these functions is putting a heavy load on the battery.

Sensors, the light, and tones are disabled while the battery usage warning is on the display.

The following are the trigger values for the functions that are monitored for battery usage.

Light: 100

Sensor Operations: 1,000

Alarm: 100

Mode Change: 1,000

The battery usage warning appears whenever any single function is performed the number of times noted above, or for any proportional number of operations of multiple functions (such as 50 light operations and 50 alarm operations, 50 light operations and 500 mode change operations, etc.).

The monitor counter continues to be incremented as long as the duration between two high power drain operations is less than 15 minutes. The counter is reset to 0 whenever 15 minutes pass between operations.

Display – Low Power Warning

The low power warning appears to let you know that battery power is low.

Sensors, the light, and tones are disabled while the low power warning is on the display.

The low power warning may appear under very low temperatures, although battery power is not low. Correct operation should resume when the watch returns to normal temperature.

If the low power warning appears under normal temperatures, have the watch’s battery replaced as soon as possible.

Be sure to read “BATTERY REPLACEMENT” before trying to replace the battery.

ABOUT ALTITUDE AND BAROMETRIC PRESSURE MEASUREMENTS

Altimeter

Generally, barometric 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), which define relationships between altitude, barometric pressure, and temperature.

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.

Barometer

Barometric pressure indicates changes in the atmosphere, and by monitoring these changes you can predict the weather with reasonable accuracy. Rising barometric 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.
