Recall Mode °C hPa mb P AUTO P RECALL C D °C m A ▼ ▲ Stopwatch Mode Alarm Mode ▼ A BACKLIGHT This watch features an electroluminescent (EL) backlight that helps you easily read the face, even in total darkness. Its Auto Backlight function automatically lights the watch face whenever you turn your wrist towards your face. Important! Avoid wearing the watch on the inside of your wrist. Doing so causes the Auto Backlight to operate when it is not needed, which shortens battery life. 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 illuminate. Note • The backlight of the watch employs an electroluminescent (EL) light, which loses illuminating power after very long use. • Frequent use of the backlight shortens the battery life. • 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 transistor 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 or when you press the C or D button. To manually turn on the backlight A B P C D In the Timekeeping Mode or the Altimeter Mode, press B to illuminate the display for about two seconds. • The backlight remains lit for about two seconds from the point you press B, even if it is already lit when you press B. If you keep B depressed for one or two minutes, the backlight will automatically turn off. Parallel to ground More than 40° • The backlight may not illuminate if the face of the watch is more than 15 degrees off parallel as shown below. Make sure that the back of your hand is parallel to the ground. Parallel to ground More than 15 degrees too high More than 15 degrees too low To switch the auto backlight function on and off In the Timekeeping Mode, hold down D for one or two seconds to turn the auto backlight function on and off. Auto backlight indicator AUTO AUTO P AUTO P ON OFF • The auto backlight indicator is shown on the display in all modes while the auto backlight function is on. • In order to protect against running down the battery, the auto backlight function is automatically turned off approximately two or three hours after you turn it on. Repeat the above procedure to turn the auto backlight function back on if you want. • Pressing B in the Timekeeping Mode or Altimeter Mode illuminates the display for about two seconds, regardless of the auto backlight function on/ off setting. About the Auto Backlight function While the Auto Backlight function is turned on, the backlight automatically lights for about two seconds in any mode whenever you position your wrist as described below. • 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 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 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. 1675-2 CHANGING THE MEASUREMENT UNITS BAROMETER FUNCTIONS You can change the measured values displayed by the watch between the following units. Altitude: meters (m) ↔ feet (ft) Temperatures: Celsius (°C) ↔ Fahrenheit (°F) Barometric Pressure: hecto-pascals/millibars (hPa/mb) ↔ 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). This watch uses a pressure sensor to measure air pressure. This sensor can be calibrated. 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. Example barometer applications * * To change the measurement units A 1. In the Timekeeping Mode, press D until the Barometric Pressure/Temperature Display appears. 2. Hold down A until “OFF” (or the temperature value) appears flashing in the display. The data on the display is flashing because it is selected. 3. Press C to change the selection in the following sequence. B °C hPa mb C D 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. • 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 display. The last measurement result, along with the current temperature is displayed in the Barometric pressure/Temperature display. Understanding the barometer display 1.

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 conditions stabilize. Not visible on display 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. 1675-3 To calibrate the barometric pressure A °C hPa mb C To calibrate the temperature 1.

ALTIMETER FUNCTIONS 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 Modes. Temperature measurements are taken every five seconds for the first three minutes after you display the Timekeeping Mode’s Barometric Pressure/Temperature display, 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. For details, see About memory data. A built-in altimeter uses a pressure sensor to detect the current air pressure, which is then used to estimate the current altitude in accordance with ISA (International Standard Atmosphere) values for altitude and air pressure. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value. Altimeter functions also include data storage memory and an altitude alarm. Important! • This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air 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: sky diving, 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: Understanding the temperature display 1. Use C to enter the Timekeeping Mode. 2. Press D to display the Barometric Pressure/Temperature Display. A B °C Temperature hPa mb P C D ( Barometric Pressure/Temperature Display ) • The display shows “– –.– °C” (or °F) if a measured value falls outside the range of –20.0°C to 60.0°C (–4.0°F to 140.0°F). The normal display will return as soon as the temperature returns within the allowable range. • For details on viewing the temperature in the Altimeter Mode, see Understanding the altimeter display. Calibrating the temperature measurement The temperature 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 temperature readings produced by the watch, you can adjust it to correct the error. Important! Incorrectly calibrating the temperature measurement of this watch can result in incorrect readings. Carefully read the following before doing anything. • Compare the readings produced by the watch with those of another reliable, 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. • Before beginning the climb, set the reference altitude to 0 m 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 m on the ground floor. Note, however, that if the building is pressurized or air conditioned, you may not be able to get a good reading. • To determine the difference in altitude between your house and another location, set the reference altitude to 0 m 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 prevent you from obtaining accurate readings: 400 When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact About altitude measurements There are two types of altitude measurements: those for displayed data (Altimeter Mode measurement) and those for memory data (memory measurements; See Memory measurements). 1675-4 Altimeter Mode measurement A B AUTO This type of measurement is performed only when the watch is in the Altimeter Mode. As soon as you enter the Altimeter Mode, measurements are taken every five seconds for the first three minutes. After that, measurements are taken every two minutes. The display unit for Altimeter Mode measurements is 5 m (20 feet), and the display range is 0 to 6000 m (0 to 19680 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. ALTI m C Press C. Understanding the altimeter display Use C to enter the Altimeter Mode. Note that once you enter the Altimeter Mode, if you do not press any button for 10 or 11 hours, the watch automatically returns to the Timekeeping Mode.

Using Auto Memory Measurement Current temperature Current altitude Current time “ALTI” flashes while a measurement is being taken every five seconds. It does not flash during the measurements taken every two minutes. “AUTO” flashes on the display while a memory measurement is in progress. The indicator stops flashing while no measurement is being performed. Auto memory measurement indicator A B AUTO ALTI °C m P C Memory measurements Memory measurements are taken independently of Altimeter Mode measurements and stored directly into memory (along with temperature measurements) for later recall. There are two types of memory measurements: “Auto Memory Measurements” and “Manual Memory Measurements”. Auto Memory Measurements With auto memory measurement, the watch continuously performs measurements whenever the minutes in the Timekeeping Mode reach 00, 15, 30, or 45, until you switch auto measurements off. The watch continues to take measurements regardless of whether or not you change modes, so you can keep a running log of temperature and altitude changes automatically. Manual Memory Measurements You can use the manual procedure to take a reading anytime you want to store your current altitude data into memory for later recall. Manual memory measurements can be performed only while the watch is in the Altimeter Mode. D • The “AUTO” indicator flashes on the display when you start auto memory measurements. The “AUTO” indicator continues to flash (indicating that measurements continue) even if you change modes. • Auto memory measurement cuts off automatically whenever there are 49 sets of data stored in memory. The 50th set of data measured when you stop the measurement operation in step 3 below is also stored in memory. 3. To stop measurements at any point, hold down D again until the watch emits a short beep. • A final measurement is taken when you switch auto memory measurement off, and that data is also stored into memory. Such data is indicated by “FIN” during the recall operation. Using Manual Memory Measurement Manual memory measurement indicator A B MANUAL About the memory... ALTI Each memory item (auto or manual) stored by the watch consists of the current altitude, plus the month, date, time, and temperature. Data is stored in the same sequence that it is input. Memory can hold a total of 50 sets of data, which is enough to store 12 hours and 15 minutes of auto memory data (if you do not take any manual readings during that time). See About memory data of this manual for details on how to recall memory data. Important! Further auto or manual memory measurements become impossible whenever memory is full. The message “FULL” on the display indicates that memory is full. Always check the amount of memory remaining before starting memory measurements, and delete data if necessary. AUTO ALTI Selecting Auto or Manual Memory Measurement Use the following procedure to switch between auto or manual memory measurement. Note that you cannot perform this operation while a preset auto memory measurement is already in progress. 1. In the Altimeter Mode, hold down A until the display clears. After 4 or 5 seconds, either “OFF” or the current reference altitude value (if set) will start to flash. The data flashes because it is selected. 2. Press C to change the selection in the following sequence. 1. Confirm that the “AUTO” indicator is shown on the display. If it is not, use the procedures under Selecting Auto or Manual Memory Measurement to select auto memory measurement. 2. Hold down D until the watch emits a short beep, indicating the start of the measurement. • The data measured when you first start auto memory measurement is also stored into memory. °C m P C D 1.

Absolute altitude expresses an absolute height above sea level. Relative altitude expresses the difference between the height of two different places. Height of building 130 m (Relative altitude) Rooftop at an altitude of 230 m above sea level (Altitude above sea level) Sea 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.
