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.
Note
∙The electro-luminescent panel loses illuminating power after very long use.
∙The illumination provided by the backlight may be hard to see when viewed under direct sunlight.
∙The watch will emit an audible sound whenever the display is illuminated. This is caused by a transformer that vibrates when the EL panel lights up. It does not indicate malfunction of the watch.
∙The backlight automatically turns off whenever an alarm sounds.
To manually turn on the backlight
In any mode, press L to illuminate the display for about two seconds.
∙The above operation turns on the backlight regardless of the current auto light switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on whenever you position your wrist as described below.
∙Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life.

To turn the auto light switch on and off
In the Timekeeping Mode, hold down D for one second to turn the auto light switch on (A-LIGHT ) and off (A-LIGHT).
∙In order to protect against running down the battery, the auto light switch is automatically turned off approximately two or three hours after you turn it on. Repeat the above procedure to turn the auto light switch back on if you want.
∙The mark next to A-LIGHT is on the display in all modes while the auto light switch is turned on.
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 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 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 traffic accident and serious personal injury.
CHANGING THE MEASUREMENT UNITS
You can change the measured values displayed by the watch between the following units.
Altitude: meters (m) ↔ feet (ft) Temperatures: Celsius (°C) ↔ Fahrenheit (°F)
*↔ inchesHg (inHg)
*Some countries call this unit hecto-pascal (hPa), while other countries call it millibars (mb). It really makes no difference, because 1 hPa = 1 mb. In this manual, we will refer to hPa/mb or hPa (mb).Barometric Pressure: hecto-pascals/millibars (hPa/mb)
Important!
∙Certain measurement functions are automatically terminated when you change the measurement units. Be sure that you perform this operation before starting actual measurements.
∙Changing the altitude unit of measurement automatically switches the altitude alarm off.
∙Changing the barometric pressure unit of measurement automatically restarts the barometric pressure graph from a new value.
∙Changing any of the units of measurement immediately starts to display newly measured data in the unit you specify. It also affects the unit of measurement for any data already stored in memory.

BAROMETER FUNCTIONS
This watch uses a pressure sensor to measure air pressure. This sensor can be calibrated.
Important!
The barometer that is 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.
Example barometer applications
∙Before going mountain climbing, you can take readings to find out the probable upcoming weather.
∙You can predict the weather for golf or other outdoor activities.
About barometric measurements
The barometer automatically takes measurements every two hours (starting from midnight), regardless of what mode you are in. Barometric pressure measurements are also taken every five seconds for three minutes after you display the Timekeeping Mode’s Barometric pressure/Temperature screen. The last measurement result, along with the current temperature is displayed in the Barometric pressure/Temperature screen.
Understanding the barometer screen
1.Use C to enter the Timekeeping Mode.
2.Press D to display the Barometric Pressure/Temperature screen.
∙If you do not press any button for 10 or 11 hours, the watch automatically returns to the Timekeeping screen.

(Barometric Pressure/Temperature)
*1 The barometric pressure graph shows the barometric readings for the past 26 hours. The flashing point on the right of the display is the point for the last measurement.
*2 The display shows “– – – – hPa/mb” (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 within the allowable range.
Using the barometric pressure graph
Changes in barometric pressure are caused by changes in the 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.
Note that if there are sudden |
|
changes in weather or tem- |
|
perature, the graph line of past |
|
measurements may run off the top |
|
or bottom of the display. The entire |
|
graph will become visible once |
Not visible on display |
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 (460 hPa/mb to 1100 hPa/mb or 13.55 inHg to 32.45 inHg)
∙Sensor malfunction
∙Dead battery
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.

∙Pressing B and D at the same time returns to the OFF display.
5.After calibrating the barometric pressure, press A to return to the Barometric Pressure/Temperature screen.
∙If you do not operate any button for a few minutes while the barometric pressure digits are flashing, the flashing stops and the watch goes back to the Barometric Pressure/Temperature screen.
THERMOMETER FUNCTIONS
A built-in temperature sensor measures temperature and shows the measured value on the display. The thermometer can be calibrated.
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 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.
About temperature measurements
Temperature measurements are taken automatically every five minutes, regardless of what mode the watch is in. Measured temperature values can be viewed in the Timekeeping or Altimeter Mode. Temperature measurements are taken every five seconds for the first three minutes after you display the Timekeeping Mode’s Barometric Pressure/Temperature screen, or after you enter the Altimeter Mode. After that, temperature measurements are taken every five minutes.
∙Temperature measurement data can be recalled along with altitude measurement data.
A falling graph generally means deteriorating weather.
