Applications

The built-in sensors of this watch measure direction, barometric pressure,

temperature and altitude. Measured values are then shown on the display.

Such features make this watch useful when hiking, mountain climbing, or

when engaging in other such outdoor activities.

If the digital display of the watch is blank...

If the PS indicator is on the display (either

flashing or steady), it means that the watch's

Power Saving function has turned it off to

conserve power. Power Saving automatically

turns off the display and enters a sleep state

whenever the watch is left for a certain period

where it is dark.

· The initial factory default setting is Power Saving on.

· The watch will recover from the sleep state if you move it to a well-lit area,*

if you press any button, or if you angle the watch towards your face for

reading.

*It can take up to two seconds for the display to turn on.

· See "Power Saving" for more information.

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.

To take barometric pressure and temperature readings

Pressing E in the the Timekeeping or in any of

other sensor modes enters the Barometer/

Thermometer Mode and automatically starts

taking barometric pressure and temperature

measurements.

· It can take up to four or five seconds for the

barometric pressure reading to appear after

you enter the Barometer/Thermometer Mode.

· Barometric pressure is displayed in units of

1hPa (or 0.05 inHg).

· The displayed barometric pressure value changes to xxxx hPa (or inHg) if

a measured barometric pressure falls outside the range of 260 hPa to 1100

hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will be

displayed again 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 xxx °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 be displayed again as soon as the

measured temperature is within the allowable range.

· In some areas, barometric pressure is expressed in millibars (mb) instead

of hecto-pascals (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

change the barometric pressure and temperature units".

· See "Barometer and Thermometer Precautions" for important precautions.

Barometric Pressure Indicators

The watch's barometric pressure indicators graphically show you whether the

barometric pressure for up to the last 15 hours has been rising, holding

steady, or falling. Since changes in barometric pressure signal changes in the

atmosphere, you can predict upcoming weather with reasonable accuracy by

looking at the current tendency of barometric pressure.

The barometric pressure indicator display area of the watch has three lines:

top, middle, and bottom. The location of each indicator tells you whether

barometric pressure is rising, steady, or falling.

Within

±2hPa of previous reading

Rise greater than 3hPa from previous

reading

Fall greater than 3hPa from previous

reading

How to Interpret Barometric Pressure Indicators

· The rightmost indicator is the newest indicator, the leftmost indicator is the

oldest indicator.

Rising pressure generally means improving weather.

Falling pressure generally means deteriorating weather.

· The locations of the indicators, not their pattern, indicates barometric

pressure tendencies.

· A series of multiple indicators in the top line of the barometric pressure

indicator display area indicates a series of rising pressure readings. It does

not indicate steady pressure at a high level.

· A series of multiple indicators in the bottom line of the barometric pressure

indicator display area indicates a series of falling pressure readings. It does

not indicate steady pressure at a low level.

· A movement of indicators from the top line to the

middle line does not indicate falling pressure, and

a movement of indicators from the bottom line to

the middle line does not indicate rising pressure. A

move to the middle line indicates that the current

pressure measurement is relatively unchanged

(within

±2hPa) from the previous measurement.

Rising pressure is not indicated until an indicator

appears in the top line, and falling pressure is not

indicated until an indicator appears in the bottom line.

· Steady pressure is indicated by a series of indicators in the middle line.

Notes

· Though you can configure the watch to display barometric pressure in units

of hPa or inHg, the barometric pressure indicator positions are always

determined based on

±3 hPa changes in barometric pressure.

· No indicator is plotted if a measurement operation cannot be performed

due to sensor malfunction, low battery power, because of the watch is in

the function sleep state, or any other reason.

Operation Guide 2872

About Barometric and Temperature Measurements

· Barometric pressure and temperature measurement operations are

performed as soon as you enter the Barometer/Thermometer Mode. After

that, barometric pressure and temperature measurements are taken every

five seconds.

· The barometer automatically takes measurements every three hours

(starting from midnight), regardless of what mode you are in. The results of

these measurements are used for positioning indicators in the barometric

pressure indicator display area.

· You can also perform a barometric pressure and temperature measurement

at any time by pressing E in the Barometer/Thermometer Mode.

Barometer and Thermometer Precautions

· The pressure sensor 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.

· Sudden temperature changes can affect pressure sensor readings.

· 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 all

moisture from the case. It takes approximately 20 to 30 minutes for the

case of the watch to reach the actual surrounding temperature.

Altimeter

A built-in altimeter uses a pressure sensor to detect the current air pressure,

which is then used to estimate the current altitude. The watch is pre-

programmed with ISA (International Standard Atmosphere) preset values,

which are used to convert air pressure readings to altitude values. If you

preset a reference altitude, the watch will also calculate the current relative

altitude based on your preset value. Memory is also provided for the storage

of altimeter data.

Important!

· This watch estimates altitude based on air pressure. This means that

altitude readings for the same location may vary if air pressure changes.

· This watch employs a semiconductor pressure sensor, which is affected by

temperature changes. Make sure that the watch is not being exposed to

temperature changes while you are taking altitude measurements.

· To avoid the effect of sudden temperature changes on measurement, wear

the watch so it is in direct contact with your wrist during measurement.

· Do not rely upon this watch for altitude measurements or perform button

operations while engaging in sports where there are sudden altitude

changes, while sky diving, hang gliding, or paragliding, or while riding a

gyrocopter, glider, or any other aircraft.

· 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 by the flight crew.

How the Altimeter Works

With the Preset Values (No Reference Altitude)

· The watch measures the air pressure at your current location and uses the

built-in ISA values to convert it to the equivalent altitude.

With a Reference Altitude

· If you set a reference altitude, the watch

uses that value when calculating altitude

based on air pressure.

· To determine the height of a tall building,

set the reference altitude to 0 on the

ground floor. Note, however, that you may

not be able to get a good reading if the

building is pressurized or air-conditioned.

· When mountain climbing, you can set the

reference value in accordance with a

marker along the way or altitude

information from a map. After you do this,

the altitude readings produced by the

watch will be more accurate than they

would be without a reference altitude.

400

To take an altitude reading

Pressing D in the Timekeeping Mode or in any

of the other sensor modes enters the Altimeter

Mode and automatically starts altitude

measurement.

· It can take up to four or five seconds for the

altitude reading to appear after you enter the

Altimeter Mode.

· The Altimeter Mode screen also displays the

current temperature. See "Barometer/

Thermometer" for more information.

· During the first three minutes after entering the

Altimeter Mode, the

indicator flashes on the

display and measurements are taken every five

seconds. After that, the

indicator disappears

as measurements are taken every two minutes.

· Pressing D causes the measurement operation to restart from the

beginning of the cycle described above.

· Altitude is displayed in units of 5 meters (20 feet).

· The measurement range for altitude is 700 to 10,000 meters (2,300 to

32,800 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.

· The displayed altitude value changes to xxxxx meters (or feet) if a

measured altitude falls outside the measurement range. The altitude value

will be displayed again as soon as the measured altitude is within the

allowable range.

· You can change the unit of measurement for the displayed altitude values

between meters (m) and feet (ft). See "To change the altitude unit".

Altitude Indicator

In the Altimeter Mode, the altitude indicator shows the current altitude reading

in meters (m). As shown in the illustration below, the altitude indicator is

divided into two zones: one for 0 to 999 meters, and one for 1000 to 10,000

meters.

Though you can specify either meters or feet for the watch's altitude

measurements, the altitude indicator always shows altitude in meters.

The above altitude indicator indicates an altitude of approximately 4,340 meters.

· The 0-999 meter zone starts from the 12 o'clock position (0 meters), and

indicates altitudes in 20-meter units.

· The 1000+ meter zone indicates altitudes in 1000-meter units.

1000+ meter zone

0-999 meter zone

Setting a Reference Altitude

After you set a reference altitude, the watch adjusts its air-pressure-to-altitude

conversion calculation accordingly. The altitude measurements produced by

this watch are subject to error caused by changes in air pressure. Because of

this, we recommend that you update the reference altitude whenever one is

available during your climb.

To set a reference altitude

1. In the Altimeter Mode, hold down A until

OFF (flashing) appears or until the display

goes blank. This is the setting screen.

· If the display goes blank, it means there is a

reference altitude value. Release A and

wait for four or five seconds until the value

appears.

2. Press D (+) or B () to change the current

reference altitude value by 5 meters (or 20

feet).

l l l l l

· You can set the reference altitude within the range of 10,000 to 10,000

meters (32,800 to 32,800 feet).

· Pressing D and B at the same time returns to OFF(no reference

altitude), so the watch performs air pressure to altitude conversions

based on preset data only.

3. Press A to exit the setting screen.

Operation Guide 2872

Altitude Records

Storing altitude data in memory creates an altitude record. If a reading is

greater than all of the other altitude readings currently stored in memory, it is

stored in the maximum altitude record. The following describes the contents

of each type of record.

Recording date (month, day), time (hour, minutes), altitude, and altitude

indicator: Up to 41 records

Maximum altitude (including recording date and time) and altitude indicator:

1 record

· The maximum altitude record shows information about the altitude record

that has the greatest altitude value. The maximum altitude record is

updated any time a reading produces an altitude that is greater than that of

the current maximum altitude record.

To store an altitude record in memory

In the Altimeter Mode, hold down D for about

one second until the watch beeps twice. This

indicates that a record of the altitude reading has

been stored in memory.

· You can recall data in memory using the Data

Recall Mode.

· Note that there is enough memory to store a

total of 41 records. If there are already 41

records in memory, storing another one

automatically deletes the oldest record to make

room for the new one.

To view altitude record data

1. Use C to enter the Data Recall Mode.

2. Press D to cycle through the altitude record screens in the sequence

shown below.

· The maximum altitude record appears first. After that, each press of D

scrolls through records in sequence, starting from the oldest record.

· If an error occurs while altitude data is being stored in memory or if there is

no altitude data in memory, xxxxx is shown for the measured altitude

value on the corresponding altitude record screen.

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 in any mode.

Note that this watch features a "Full Auto EL Light", so the auto light switch

operates only when available light is below a certain level. It does not turn on

the backlight under bright light.

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 turn on.

· Wear the watch on the outside of your wrist.

Warning!

· Always make sure you are in a safe place whenever you are reading

the display of the watch using the auto light switch. Be especially

careful when running or engaged in any other activity that can result

in accident or injury. Also take care that sudden illumination by the

auto light switch does not surprise or distract others around you.

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
