Note

•You also need to enter the Timekeeping Mode in order to configure the following settings.

Power saving on/off (“To turn Power Saving on and off”) Temperature, barometric pressure, and altitude units (“To select the temperature, barometric pressure, and altitude units”)

•The year can be set in the range of 2000 to 2099. The day of the week is calculated automatically in accordance with the date you set.

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 temperature sensor and the pressure sensor if you suspect that readings are incorrect.

•The displayed barometric pressure value changes to xxxx hPa (or inHg) if a measured barometric pressure falls outside the range of 260 hPa to

1,100 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 xx.x °C (or °F) if a 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 30 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.

A rising graph generally means improving 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 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 to 1,100 hPa 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.

About Barometric and Temperature Measurements

•Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, they are taken at five-second intervals.

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

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. You can configure an altimeter alarm that sounds whenever the measured altitude reaches a value you preset. 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.
