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.

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

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.

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.

OFFON

• 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.

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.

• 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 Example barometer 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.

After calibrating the temperature, press A to return to the Barometric Pressure/Temperature Display. • If you do not operate any button for a few minutes while the temperature digits are flashing, the flashing stops and the watch goes back to the Barometric Pressure/Temperature Display. 3. Press C to show the barometric pressure calibration display. At this time, “OFF” or the barometric pressure value should be flashing on the display.

ABOUT ALTITUDE AND AIR PRESSURE MEASUREMENTS Altimeter Generally, air 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, air pressure, and temperature. ALTITUDE AIR PRESSURE 472 hPa/mb 6000 m TEMPERATURE About 6.7 hPa/mb per 100 m 5500 m 5000 m 4500 m 4000 m 3500 m 3000 m –17.
