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.
Notes
· 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.
To manually turn on the backlight
In any mode, press E to illuminate the display for about two seconds.
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.

· In order to protect against running down the battery, the auto backlight
function is automatically turned off approximately three hours after you
turn it on. Repeat the above procedure to turn the auto backlight function
back on if you want.
· Pressing E in any 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 to the left or right. Make sure that the back of your
hand is parallel to the ground.
· The auto backlight indicator is shown on the display in all modes while
the auto backlight function is on.
· 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.
GENERAL GUIDE
· Press C to change from mode to mode. Hold down C for one or two
seconds in any mode to switch back to the Timekeeping Mode.

Digital Compass Precautions
This watch features a built-in magnetic bearing sensor that detects
terrestrial magnetism. This means that the northern direction indicated by
this watch is magnetic north, which is somewhat different from true polar
north. The magnetic north pole is located in northern Canada, while the
magnetic south pole is in southern Australia. Note that the difference
between magnetic north and true north as measured with all magnetic
compasses tends to be greater as one gets closer to either of the magnetic
poles. You should also remember that some maps indicate true north
(instead of magnetic north), and so you should make allowances when
using such maps with this watch.
Location
· Using the Digital Compass when you are near a
source of strong magnetism can cause large errors in
readings. Because of this, you should avoid using the
Digital Compass while in the vicinity of the following
types of objects: permanent magnets (magnetic
necklaces, etc.), concentrations of metal (metal doors,
lockers, etc.), high tension wires, aerial wires, household appliances (TVs,
personal computers, washing machines, freezers, etc.)
· Accurate direction measurements are impossible while in a train, boat, air
plane, etc.
· Accurate measurements are also impossible indoors, especially inside
ferroconcrete structures. This is because the metal framework of such
structures picks up magnetism from appliances, etc.
Storage
· The precision of the compass may deteriorate if the watch becomes
magnetized. Because of this, you should be sure to store the watch away
from magnets or any other sources of strong magnetism, including:
permanent magnets (magnetic necklaces, etc.) and household
appliances (TVs, personal computers, washing machines, freezers, etc.)
· Whenever you suspect that the watch may have become magnetized,
perform one of the calibration procedures under "Calibrating the Digital
Compass".
Calibrating the Digital Compass
Whenever you suspect that the readings produced by the Digital Compass
are wrong, you should calibrate it. You can use either one of two calibration
procedures:
bidirectional calibration or northerly calibration.
You should use bidirectional calibration when you want to calibrate the Digital
Compass to operate within an area exposed to magnetic force. This type of
calibration should be used if the watch become magnetized for any reason.
With northerly calibration, you "teach" the watch which way is north (which
you have to determine with another compass or some other means). You
could use this calibration procedure, for example, to set the watch to
indicate true north instead of magnetic north.
Important!
· If you want to perform both bidirectional and northerly calibration, be sure
to perform bidirectional calibration first, and then perform northerly
calibration. This is necessary because bidirectional calibration cancels
any previously set northerly calibration setting.
· If you do not perform any button operation for two or three minutes while
either calibration procedure is in progress (while the magnetic north
indicator is flashing at the 12 or 6 o'clock position), the watch
automatically returns to the Digital Compass Mode.
· The more correctly you perform bidirectional calibration, the better the
accuracy of your Digital Compass readouts. You should perform
bidirectional calibration whenever you change environments where you
use the Digital Compass, and whenever you feel that the Digital Compass
is producing incorrect readings.
To perform bidirectional calibration
1. While in the Digital Compass Mode
(Normal Display), hold down A until the
upper display changes to show "1".
· At this time, the magnetic north indicator
flashes at the 12 o'clock position to
indicate that the watch is ready to
calibrate the first direction.
2. Place the watch on a level surface, and
press B to calibrate the first direction.
· When the calibration procedure is complete,
the message "OK" appears in the upper
display. This soon changes to "2" and the
magnetic north indicator flashes at the 6
o'clock position to indicate that the watch is
ready for the second direction.

B
C
BEARING
A
S

E
3. Rotate the watch 180 degrees.
4. Press B again to calibrate the second direction.
· When the calibration procedure is complete, the message "OK" appears
in the upper display. After a short while, the watch automatically returns
to the Digital Compass Mode.
Precautions about bidirectional calibration
· You can use any two opposing directions for bidirectional calibration. You
must, however, make sure that they are 180 degrees opposite each
other. Remember that if you perform the procedure incorrectly, you will
get wrong readings from the Digital Compass.
· Do not move the watch during the one or two seconds (from the point you
press B up to the point that "OK" appears in the upper display) that the
calibration of each direction is in progress. If you do, the message "ERR"
appears in the upper display. When this happens, restart the bidirectional
calibration procedure from the beginning.
· The appearance of "ERR" during bidirectional calibration can also be
caused by local interference. If you suspect that this is the case, move to
another location and try the procedure again.
· You should perform bidirectional calibration in an environment that is the
same as that where you plan to be using the Digital Compass. If you plan
to use it in an open field, for example, calibrate in an open field.
To perform northerly calibration
1. While in the Digital Compass Mode
(Normal Display), hold down A until the
upper display changes to show "1".
2. Press C to start the northerly calibration
procedure.
· At this time, the indicator "N" appears in
the upper display.
3. Place the watch on a level surface, and
position it so that its 12 o'clock position
points north (as measured with another
compass).
4. Press B to start the calibration
operation.
· When the calibration procedure is complete, the message "OK" appears
in the upper display. After a short while, the watch automatically returns
to the Digital Compass Mode.

ALTIMETER FUNCTIONS
A built-in altimeter uses a pressure sensor to detect the current air
pressure which is then used to estimate the current altitude in accordance
with ISA (International Standard Atmosphere) values for altitude and air
pressure. If you preset a reference altitude, the watch will also calculate the
current relative altitude based on your preset value. Altimeter functions
also include data storage memory and an altitude alarm.
Important!
· This watch estimates altitude based on air pressure. This means that
altitude readings for the same location may vary if air pressure changes.
· Sudden changes in the weather make it impossible to produce accurate
altitude readings.
· This watch employs a semiconductor pressure sensor, which is affected
by temperature changes. When taking altitude measurements, be sure to
do so while ensuring that the watch is not exposed to temperature
changes.
· Do not use this watch while participating in sports where there are
sudden altitude changes. Also, do not use this watch for applications that
demand professional or industrial level precision. This watch should not
be used while engaging in the following activities: sky diving, hang
gliding, paragliding, gyrocopter riding, glider riding, etc.
-- 6 --
Applications
When no reference altitude is preset:
· The watch produces approximate altitude readings.
When a reference altitude is preset:
· Before beginning the climb, set the reference altitude to 0 m at the foot of
the mountain. This makes it possible to determine the difference in
altitude between the reference point and your destination.
· To determine the height of a tall
building, set the reference
altitude to 0 m on the ground
floor. Note, however, that if the
building is pressurized or air
conditioned, you may not be
able to get a good reading.
· To determine the difference in altitude between your house and the
another location, set the reference altitude to 0 m at your house, and then
check the reading when you arrive at the other location.
About altitude measurements
There are two types of altitude measurements: those for displayed data
(Altimeter Mode measurements) and those for memory data (see "Memory
measurements").
Altimeter mode measurement
This type of measurement is performed only when the watch is in the
Altimeter Mode. As soon as you enter the Altimeter Mode, measurements
are taken every five seconds for the first three minutes. After that,
measurements are taken every two minutes. The display unit for Altimeter
Mode measurements is 5 m, and the measurement range is 0 to 4000 m.
· The measured altitude may be a negative value in cases where there is a
reference altitude value set or because of certain atmospheric conditions.
Understanding the altimeter display
Use C to enter the Altimeter Mode. Note that once you enter the Altimeter
Mode, if you do not press any button for 10 or 11 hours, the watch
automatically returns to the Timekeeping Mode.
*1 "ALTI" flashes while a measurement is being taken every five seconds.
It does not flash during measurements taken every two minutes.
*2 "AUTO" flashes on the display while a memory measurement is in
progress. The indicator stops flashing while no measurement is being
performed.
*3" AL " appears on the display when the altitude alarm is switched on.
Memory measurements
Memory measurements are taken independently of Altimeter Mode
measurements and stored directly into memory (along with temperature
measurements) for later recall. With memory measurement, the watch
continuously performs measurements whenever the minutes in the
Timekeeping Mode reach 00, 15, 30, or 45, until you switch memory
measurements off. The watch continues to take measurements regardless
of whether or not you change modes, so you can keep a running log of
altitude and temperature changes automatically.
About the memory...
The memory item stored by the watch consists of the current altitude, plus
the month, date, time, and temperature. Data is stored in the same
sequence that it is input.
Memory can hold a total of 50 sets of data, which is enough to store 12
hours and 15 minutes of memory data. See "To recall altitude measurement
data from memory" for details on how to recall memory data.
Important!
Further memory measurements become impossible
whenever memory is full. The message "FULL" on
the display indicates that memory is full. Always
check the amount of memory remaining before
starting memory measurements, and delete data if
necessary.

the watch emits a short beep, indicating
the start of the measurement.
· The data measured when you first start
memory measurement is also stored into
memory.
· The "AUTO" indicator flashes on the
display when you start memory
measurements. The "AUTO" indicator
continues to flash (indicating that
measurements continue) even if you
change modes.
· Auto memory measurement cuts off automatically whenever there are 49
sets of data stored in memory. The 50th set of data measured when you
stop the measurement operation in step 2 below is also stored in memory.
2. To stop measurements at any point, hold down D again until the watch
emits a short beep.
· A final measurement is taken when you switch memory measurement off,
and that data is also stored into memory. Such data is indicated by "FIN"
during the recall operation.
Setting a Reference Altitude
After you set a reference altitude, the watch automatically calculates the
difference between the current altitude and your preset value. The altitude
measurements produced by this watch are subject to error caused by
changes in atmospheric pressure. Because of this, we recommend that you
set the reference altitude during your climb whenever one is available.
1. In the Altimeter Mode, hold down A until
the display clears. After 4 or 5 seconds,
either "OFF" or the current reference
altitude value (if set) will start to flash.
The data flashes because it is
selected.

BAROMETER FUNCTIONS
This watch uses a pressure sensor to measure atmospheric pressure. This
sensor can be calibrated.
Important!
The barometer that is built into this watch measures changes in
atmospheric 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.
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.
About barometric measurements
The barometer automatically takes measurements every two hours (starting
from midnight), regardless of what mode you are in. The last measurement
result, along with the current temperature is displayed in the Timekeeping Mode.
Understanding the barometer display
1. Use C to enter the Timekeeping Mode.
2. Press D to display the Barometric Pressure/Temperature Display.
*1 The barometric pressure graph shows the barometric readings for the
past 26 hours. The flashing point on the right of the display is the point
for the last measurement.
*2 Some countries call to this unit as hecto-pascal (hPa), while other
countries call it millibars (mb). It really makes no difference, because
1 hPa = 1 mb. In this manual, we will refer to hPa/mb or hPa (mb).
*3 The display shows " hPa/mb" if a measured value falls outside
the range of 610 hPa/mb to 1100 hPa/mb. The normal display will return
as soon as the pressure returns within the allowable range.
Using the barometric pressure graph
Changes in barometric pressure are caused by changes in the weather and
temperature. The following shows how to interpret the data that appears on
the barometric pressure graph.
A rising graph generally means better
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 atmospheric
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 (610 hPa/mb to 1100 hPa/mb)
· Sensor malfunction

In the Altimeter Mode, the graphic display normally indicates the counting of
the current time's seconds. When a memory measurement operation is being
performed while the altitude alarm is on, however, the watch automatically
divides the graphic display into 10 equal parts. Each part represents 1/10 of
the difference between the first altitude measured by the memory
measurement operation and the value you set as the altitude alarm. The
graphic representation gives you some idea of how much farther you must
go to reach the altitude indicated by the altitude alarm setting.
· The graphic representation described below is not shown on the display if
the altitude alarm is switched off.
Example: When the initially measured altitude is less than the altitude
alarm setting.
The graphic display would appear as
illustrated here when your current altitude is
700 meters, after you set the altitude alarm
for 1000 meters and the initial
measurement was 0 meters. Note that
seven segments of the graph are darkened
because you are 7/10 of the way to the
value set for the altitude alarm.
· Segments in the graphic display darken as you approach the altitude
alarm setting. If you descend away from the altitude alarm setting, the
darkened segments are cleared from the graphic display.
· All 10 segments are darkened when you reach or exceed the altitude set
for the altitude alarm.
· If your current altitude is lower than that registered for the initial
measurement, none of the graphic display segments are darkened.
Example: When the initially measured altitude is greater than the altitude
alarm setting.
The graphic display would appear as
illustrated here when your current altitude is
1500 meters, after you set the altitude
alarm for 1000 meters and the initial
measurement was 2000 meters. Note that
five segments of the graph are darkened
because you are 5/10 of the way to the
value set for the altitude alarm.
