TIMEKEEPING FUNCTION

While in the Timekeeping Mode, press

D to switch be-

tween the 12-hour and 24-hour formats.

• When 12-hour format is selected, the indicator P ap-

pears on the display to indicate “p.m.” times. There is

no indicator for “a.m.” times. Selecting the 24-hour for-

mat causes the 24 to appear on the display.

To set the time and date

1. Hold down

A while in the Timekeeping Mode until the

seconds digits start to flash on the display. The sec-

onds flash because they are

selected

2. Press

C to change the selection in the following se-

quence.

3. While the seconds digits are selected (flashing), press

D to reset the seconds to

“00”. If you press

D while the seconds count is in the range of 30 to 59, the sec-

onds are reset to “00” and 1 is added to the minutes. If the seconds count is in the

range of 00 to 29, the minutes count is unchanged.

4. While any other digits

(

besides seconds

)

are selected (flashing), press

D to in-

crease the number or

B to decrease it. Holding down either button changes the

current selection at high speed.

5. After you make your settings, press

A to return to the Timekeeping Mode.

• The day of the week is automatically set in accordance with the date.

• The date can be set within the range of January 1, 2000 to December 31, 2039.

• If you do not operate any button for a few minutes while a selection is flashing, the

flashing stops and the watch goes back to the Timekeeping Mode automatically.

ABOUT THE BACKLIGHT

About the Auto Light Switch Function

When the auto light switch function is turned on, the backlight automatically turns on

for two seconds under the conditions described below. Avoid wearing the watch on

the inside of your wrist. Doing so causes the auto light switch to operate when not

needed, which shortens battery life.

Moving the watch to a position that is parallel to the ground and then tilting it

towards you approximately 40 degrees causes the backlight to illuminate.

• The backlight may not illuminate if the face of the watch is more than 15 degrees off

parallel to the left or right. Make sure that the back of your hand is parallel to the

ground.

Parallel to ground More than 15 degrees More than 15 degrees

too high too low

• 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.

ON OFF

• The auto light switch indicator is shown on the display in all modes while the auto

light switch function is on.

• In order to protect against running down the battery, the auto light switch function is

automatically turned off approximately six hours after you turn it on. Repeat the

above procedure to turn the auto light switch function back on if you want.

• While in the Timekeeping Mode, Barometer Mode and Alarm Mode, press

B to

illuminate the display for about 1.5 seconds, regardless of the auto light switch’s

on/off setting.

Caution

• The backlight of this watch employs an electro-luminescent (EL) light, which loses

its illuminating power after very long term use.

• Frequent use of the backlight shortens the battery life.

• The watch emits an audible sound whenever the display is illuminated. This is be-

cause the EL light vibrates slightly when lit. It does not indicate malfunction of the

watch.

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 on a roadside or in any other

location where there might be vehicular or pedestrian traffic. Doing so is dan-

gerous 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 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 light switch can create a dis-

traction, which can result in a traffic accident and serious personal injury.

BAROMETER FUNCTIONS

This watch uses a pressure sensor to measure barometric pressure. The readout

from the pressure sensor can also be switched between hPa(mb) and inHg. The

barometer can be calibrated to correct for measurement error.

Important!

The barometer that is built into this watch measures changes in barometric 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.

How to interpret barometric readings

• Barometric pressure indicates changes in barometric conditions, and you can pre-

dict weather with reasonable accuracy by monitoring these changes. Rising baro-

metric pressure indicates good weather, while falling pressure indicates deteriorat-

ing weather conditions.

• The barometric pressure you see in the newspaper and on TV weather reports are

measurements that are corrected to 0 m sea level values.

Example barometer applications

• Measurement of barometric changes while hiking to predict coming weather.

• Measurement of barometric differences at different altitudes while mountain climb-

ing.

• Prediction of weather for golf or other outdoor activities.

Switching between hPa(mb) and inHga

1. Use

C to enter the Barometer Mode.

2. Hold down

A for about two seconds. In about 6 sec-

onds, the barometric pressure value should start flash-

ing on the display.

3. Press

C to select either “hPa(mb)” and “inHg”.

4. After you select “hPa(mb)” or “inHg”, press

A to return

to the Barometer Mode.

147-2 Barometric Pressure Monitor Function The Barometric Pressure Monitor Function automatically takes barometric readings every three hours (starting from midnight). The measured values are shown on a barometric pressure graph that shows changes in pressure at a glance. • The barometric pressure graph is shown on the display in any mode.

2147-3 Altitude change display ALARM FUNCTIONS When you start measurement (step 2 in the procedure below), the first altitude measurement is used as a base. Then, each subsequent measurement is compared with the base, and the difference is shown on the display. Measurements are taken every 2 seconds for the first five minutes. After that, measurement are taken every minute. To use the altitude change display Altitude change 1. Use C to enter the Altimeter Mode. 2.

2147-4 THINGS TO KNOW ABOUT ALTITUDES Relationships between altitude, barometric pressure, and temperature Generally, barometric pressure and temperature decrease as altitude increases. This watch bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO), which define relationships between altitude, barometric pressure, and temperature.
