Important!

• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure

readings produced by its pressure sensor. This means that readings taken at different times at the same location may produce different altitude values due to changes in barometric pressure. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

• When using the watch’s altimeter while mountain climbing, be sure to perform regular calibration in

accordance with the local altitude (elevation) indications. For more information, see “To specify a reference altitude value” (page E-70).

• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other

activities, be sure always to take along another compass to conﬁ by the digital compass of this watch are different from those of the other compass, perform ﬁ gure 8 calibration or 3-point calibration of the digital compass to ensure more accurate readings.

Important!

• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or

totally white, depending on the watch model). The appearance of the LCD should become normal again when the watch returns to a lower temperature.

• Enable the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright

light when storing it for long periods. This helps to ensure that power does not run down.

• 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 power to run down. Expose the watch to bright light whenever possible.

Power Levels

Hold down B for at least two seconds to enter the Timekeeping Mode. You can get an idea of the watch’s power level by observing the battery power indicator on the display.

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Whenever you are not wearing the watch, leave it in a location where it is exposed to light.

• Best charging performance is

achieved by exposing the watch to the strongest light available.

Warning! Leaving the watch in bright light for charging 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 conditions below for long periods.

• Leaving the watch exposed to direct sunlight or some other very strong light source can cause the

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

• 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 5 and when you have the battery replaced.

A dark environment while battery power is at Level 4 will cause the level to drop to Level 5. Expose the

watch to bright light whenever possible.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Conﬁ guring Current Time and Date Settings Manually” (page E-36) for more information. This section explains how the watch updates its time settings automatically when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

If your Home City Code setting is this:

LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainﬂ ingen (Germany)

HKG, BJS Shangqiu City (China)

• Even when the watch is within range of a transmitter, signal reception may be impossible due to the

effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the inﬂ

uence of the conditions listed above becomes even greater.

Hand Home Position Adjustment

If the watch is exposed to strong magnetism or impact, its hands can go out of alignment with the time on the digital display. This can result in incorrect time indication even though a time calibration signal is being received. The watch periodically corrects hand positions automatically. You can also use the procedure below to trigger hand position adjustment manually when required.

To trigger hand home position adjustment manually

Wait until all of the hands move to 12 o’clock.

Note

After performing the above steps, enter the Timekeeping Mode and check to make sure that the analog hands and the display indicate the same time. If they do not, trigger home position adjustment again.

Taking Barometric Pressure Readings

This watch uses a pressure sensor to measure air pressure (barometric pressure).

Barometric Pressure Graph

How to interpret the data that appears on the Barometric Pressure Graph is shown below.

Note

• If there are sudden changes in weather or temperature, the graph line of past

readings may run off the top or bottom of the display.

• The conditions below cause the barometric pressure reading 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

• The Barometric Pressure Graph is not displayed while the barometric pressure change indicator is

displayed.

Specifying the Barometric Pressure Auto Measurement Interval

You can select either of two barometric pressure auto measurement interval times for drawing the Barometric Pressure Graph. 0:30: 30-minute measurement interval 2:00: 2-hour measurement interval

E-46

To take barometric pressure readings

While in the Timekeeping Mode or a sensor mode, use A to cycle through the sensor modes until “Selecting a Mode” (page E-30).

• This enters the Barometer Mode and displays a barometric pressure

reading after about one second.

• After a barometric pressure reading operation is started, the watch will

take readings every ﬁ every two minutes after that.

• The watch will return to the Timekeeping Mode automatically if you do

not perform any operation for about one hour after entering the Barometer Mode.

Rising barometric pressure indicates that upcoming weather will improve.

Falling barometric pressure indicates that upcoming weather will deteriorate.

Barometric Pressure

• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).

• The displayed barometric pressure value changes to

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.

Display Units

You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure. See “To specify altitude, depth, barometric pressure, and temperature units” (page E-43).

Barometric Pressure Differential Pointer

Barometric pressure differential pointer

Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. Your watch can be conﬁ gured to take barometric pressure readings automatically every two hours or every 30 minutes. Readings are used to produce Barometric Pressure Graph and to determine the barometric pressure differential pointer position.

• The horizontal axis of the graph represents time, with each dot

standing for either two hours or 30 minutes (depending on the watch settings). 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 value and that of the dots next to it. Each dot represents 1 hPa.

1. In the Barometer Mode, pull out the crown.

• This will cau se the current barometri c pressure reading value to
