Important!
•Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure
measurement by its pressure sensor. For more information, see pages E-51 and E-65.
•Immediately before embarking or otherwise taking altitude readings, be sure to specify a reference
altitude. If you don’t the readings produced by the watch probably will not be very accurate. For more
information, see “To specify a reference altitude value” (page E-58).
•To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before
using it. The watch may produce incorrect direction readings if you do not perform bidirectional
calibration. For more information, see “To perform bidirectional calibration” (page E-30).

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.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
•The watch may enter a sleep state
(page E-13) if its face is blocked
by your sleeve even only partially.
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 following conditions for long periods.
•On the dashboard of a car parked in direct sunlight
•Too close to an incandescent lamp
•Under direct sunlight
E-10
Important!
•Allowing the watch to become very hot can cause its liquid crystal display to black out. The
appearance of the LCD should become normal again when the watch returns to a lower temperature.
•Turn on the watch’s Power Saving function (page E-13) 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.
E-11
Power Levels
You can get an idea of the watch’s power level by observing the battery power indicator on the display.
Level Battery Power Indicator Function Status
1
(H) All functions enabled.
2
(M) All functions enabled.
3
(L)
Illumination, beeper, and sensor operation
disabled.
4
(CHG)
Except for the current time and the CHG
(charge) indicator, all functions and display
indicators disabled.
5 – – – All functions disabled.
•The flashing LOW indicator at Level 3 (L) tells you that battery power is very low, and that exposure to
bright light for charging is required as soon as possible.
•At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery
reaches Level 2 (M) after falling to Level 5, reconfigure the current time, date, and other settings.

E-12
•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
•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.
Power Recovery Mode
•Performing multiple sensor, illumination, or beeper operations during a short period may cause all of
the battery power indicators (H,M, and L) to start flashing on the display. This indicates that the watch
is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and
sensor operations will be disabled until battery power recovers.
•Battery power will recover in about 15 minutes. At this time, the battery power indicators (H,M,L) will
stop flashing. This indicates that the functions listed above are enabled again.
•If all of the battery power indicators (H,M,L) are flashing and the CHG (charge) indicator also is
flashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.
•Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available
to power it sufficiently. This is indicated when all of the battery power indicators (H,M,L) are flashing.
•Frequent flashing of all of the battery power indicators (H,M,L) probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.

Taking Direction Readings
The Digital Compass Mode uses a built-in direction sensor to take direction readings and display the
results. North is indicated by three graphic segments ( ). The watch also displays literal indications of
direction that its 12 o’clock position is currently pointed.
•For information about what you can do to improve digital compass reading accuracy, see “Calibrating
the Bearing Sensor” (page E-28) and “Digital Compass Precautions” (page E-38).
E-26
To take a direction reading
1. Make sure the watch is in the Timekeeping Mode or any one of the
sensor modes.
•The sensor modes are: Digital Compass Mode, Barometer/
Thermometer Mode, and Altimeter Mode.
2. Place the watch on a flat surface. If you are wearing the watch, make
sure that your wrist is horizontal (in relation to the horizon).
3. Point the 12 o’clock position of the watch in the direction whose
reading you want to take.
4. Press Cto start.
•COMP will appear in the upper display to indicate that a digital
compass operation is in progress.
•About one second after you press C, pointers (three graphic
segments for north, one graphic segment each for south, east, and
west) will appear on the display to indicate north, south, east, and
west. Direction will also be indicated by literal direction indicators
and by a direction angle.

information. If this happens, press Eto delete the current bearing memory contents. For more
information, see “Using Bearing Memory” (page E-32).
•To return to the Timekeeping Mode, press D.
Pressing Dwill return to the Timekeeping Mode even is a reading operation is in progress.
Digital Compass Readings
•When you press Cto start digital compass reading operation, COMP will initially appear on the
display to indicate that a digital compass operation is in progress.
•After the first reading is obtained, the watch will continue to take digital compass readings automatically
each second for up to 60 seconds. After that, the reading operation will stop automatically.
•The direction indicator and angle value will show - - - to indicate that digital compass readings are
complete.
•The auto light switch is disabled during the 60 seconds that digital compass readings are being taken.
•The following table shows the meanings of each of the direction abbreviations that appear on the
display.

northeast NE Northeast ENE East- northeast
EEast ESE East-
southeast SE Southeast SSE South- southeast
SSouth SSW South-
southwest SW Southwest WSW West- southwest
WWest WNW West-
northwest NW Northwest NNW North- northwest
•The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
•Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can
result in large direction reading error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
•Any ongoing direction reading operation is paused temporarily while the watch is performing an alert
operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by
pressing L). The direction reading operation resumes for its remaining duration after the operation
that caused it to pause is finished.
•See “Digital Compass Precautions” (page E-38) for important information about taking direction readings.
Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off. You can use any one of two different bearing sensor calibration methods: bidirectional
calibration or magnetic declination correction.
E-29
•Bidirectional Calibration
Bidirectional calibration calibrates the bearing sensor in relation to magnetic north. Use bidirectional
calibration when you want to take readings within an area exposed to magnetic force. This type of
calibration should be used if the watch becomes magnetized for any reason.
Important!
•To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before
using it. The watch may produce incorrect direction readings if you do not perform bidirectional
calibration.
•Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle (difference between
magnetic north and true north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are using. Note that you can
input the declination angle in whole degree units only, so you may need to round off the value specified
on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6°
input 8°, for 7.5° you can input 7° or 8°.
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 bearing sensor readings.
•Do not move the watch while calibration of either direction is in progress.
•You should perform bidirectional calibration in an environment that is the same as that where you plan
to be taking direction readings. If you plan to take direction readings in an open field, for example,
calibrate in an open field.
E-30
To perform bidirectional calibration
1. In the Digital Compass Mode, hold down Efor at least two seconds.
First, SET Hold will flash on the display. After that, CALIBRATION will
scroll across the upper display. Keep Edepressed until
CALIBRATION starts scrolling.
•At this time, the north pointer flashes at the 12 o’clock position
and the display will show -1- to indicate that the watch is ready to
calibrate the first direction.
2. Place the watch on a level surface facing any direction you want, and
press Cto calibrate the first direction.
•- - - is shown on the display while calibration is being performed.
When calibration is successful, Turn 180° will appear on the
display and three graphic segments ( ) will flash at 6 o’clock.
After about one second, CALIBRATION -2- will scroll across the
upper display.
•If ERR-1 appears on the display, press Cagain to restart the
direction reading operation.
3. Rotate the watch 180 degrees.
4. Press Cagain to calibrate the second direction.
•- - - is shown on the display while calibration is being performed.
When calibration is successful, the display will show OK and then
change to the Digital Compass Mode screen.
E-31
To perform magnetic declination correction
1. In the Digital Compass Mode, hold down Efor at least two seconds.
First, SET Hold will flash on the display. After that, CALIBRATION will
scroll across the upper display. Keep Edepressed until
CALIBRATION starts scrolling.
2. Press D.
•DEC 0° will appear on the display and then the current magnetic
declination angle setting will flash on the display.
3. Use A(East) and C(West) to change the settings.
• The following explains magnetic declination angle direction
settings.
OFF: No magnetic declination correction performed. The magnetic
declination angle with this setting is 0°.
E: When magnetic north is to the east (east declination)
W: When magnetic north is to the west (west declination)
•You can select a value within the range of W 90° to E 90° with
these settings.
•You can turn off (OFF) magnetic declination correction by pressing
Aand Cat the same time.
•The illustration, for example, shows the value you should input
and the direction setting you should select when the map shows a
magnetic declination of 1° West.

Using Bearing Memory
Bearing Memory lets you temporarily store and display a direction
reading so you can use it as a reference as you take subsequent digital
compass readings. The Bearing Memory screen displays the direction
angle for the stored reading, along with a pointer that indicates the stored
reading.
When you take digital compass readings while the Bearing Memory
screen is displayed, the direction angle of the current digital compass
reading (as read from the 12 o’clock position of the watch) and the stored
Bearing Memory direction reading will both be shown.
To store a direction angle reading in Bearing Memory
1. Press Cto start a digital compass reading operation (page E-26).
•This will take an initial reading and then take readings every
second for 60 seconds.
•If a bearing memory direction angle value is already displayed, it

E
to store the current
reading in Bearing Memory.
•The Bearing Memory direction angle flashes for about one second as it is stored in Bearing
Memory. After that, the Bearing Memory screen (which shows the bearing memory direction angle
and pointer) will appear, and a new 60-second direction reading operation will start.
•You can press Cat any time while the Bearing Memory screen is displayed, to start a new
60-second direction reading operation. Doing so will display the direction angle for the direction
that the 12 o’clock position of the watch is pointed. The direction angle of the current reading will
disappear from the display after the 60-second direction reading operation is complete.
•During the first 60 seconds after you display the Bearing Memory screen or during a 60-second
direction reading operation you triggered by pressing Cwhile the Bearing Memory screen is on
the display, the direction stored in memory is indicated by a Bearing Memory pointer.
•Pressing Ewhile the Bearing Memory screen is displayed will clear the reading currently in
Bearing Memory and start a new 60-second direction reading operation.
Using the Digital Compass While Mountain Climbing or Hiking
This section provides three practical applications for using the watch’s built-in digital compass.
•Setting a map and finding your current location
Having an idea of your current location is important when mountain climbing or hiking. To do this, you
need to “set the map”, which means to align the map so the directions indicated on it are aligned with
the actual directions of your location. Basically what you are doing is aligning north on the map with
north as indicated by the watch.
•Finding the bearing to an objective
•Determining the direction angle to an objective on a map and heading in that direction
E-34
To set a map and find your current location
1. With the watch on your wrist, position it so the face is horizontal.
2. While in the Timekeeping Mode or in any of the sensor modes, press Cto take a compass reading.
•The reading will appear on the display after about one second.
3. Rotate the map without moving the watch so the northerly direction
indicated on the map matches north as indicated by the watch.
•If the watch is configured to indicate magnetic north, align the
map’s magnetic north with the watch indication. If the watch has
been configured with a declination to correct to true north, align
the map’s true north with the watch indication. For details, see
“Calibrating the Bearing Sensor” (page E-28).
•This will position the map in accordance with your current location.
4. Determine your location as you check the geographic contours around
you.

To find the bearing to an objective
1. With the watch on your wrist, position it so the face is horizontal.
2. Set the map so its northerly indication is aligned with north as indicated
by the watch, and determine your current location.
•See “To set a map and find your current location” on page E-34 for
information about how to perform the above step.
3. Next, set the map so the direction you want to travel on the map is
pointed straight in front of you.
4. While in the Timekeeping Mode or in any of the sensor modes, press
Cto take a compass reading.
•The reading will appear on the display after about one second.
5. Still holding the map in front of you, turn your body until north as
indicated by the watch and the northerly direction on the map are
aligned.
•This will position the map in accordance with your current location,
so the bearing to your objective is straight ahead of you.

To determine the direction angle to an objective on a map and head in that direction (Bearing Memory)
1. Set the map so its northerly indication is aligned with north as indicated
by the watch, and determine your current location.
•See “To set a map and find your current location” on page E-34 for
information about how to perform the above step.
2. As shown in the illustration to the left, change your position so you (and
the 12 o’clock position of the watch) are pointed in the direction of
objective, while keeping the northerly direction indicated on the map
aligned with north as indicated by the watch.
•If you find it difficult to perform the above step while keeping
everything aligned, first move into the correct position (12 o’clock
position of the watch pointed at the objective) without worrying
about the orientation of the map. Next, perform step 1 again to set
the map.

3. While in the Timekeeping Mode or in any of the sensor modes, press
Cto take a compass reading.
4. While direction angle readings are in progress, press Eto record the
currently displayed direction in Bearing Memory.
•The direction angle value and pointer stored in Bearing Memory
will remain on the display for about 60 seconds.
•To re-display the Bearing Memory direction angle value and
Bearing Memory pointer, press C.
•See “Using Bearing Memory” (page E-32) for more information.
5. Now you can advance while monitoring the Bearing Memory pointer to
ensure that it remains in the 12 o’clock position.
•Pressing Ewhile the Bearing Memory direction angle value and
Bearing Memory pointer are on the display will clear the Bearing
Memory data you saved in step 3 and save the current direction
reading in Bearing Memory.
Note
•When mountain climbing or hiking, conditions or geographic
contours may make it impossible for you to advance in a straight
line. If this happens, return to step 1 and save a new direction to
the objective.

Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as magnetic north or true
north, which are different from each other. Also, it is important to keep in mind
that magnetic north moves over time.
•Magnetic north is the north that is indicated by the needle of a compass.
•True north, which is the location of the North Pole of the Earth’s axis, is the
north that is normally indicated on maps.
•The difference between magnetic north and true north is called the
“declination”. The closer you get to the North Pole, the greater the
declination angle.
Location
•Taking a direction reading when you are near a source of strong magnetism can cause large errors in
readings. Because of this, you should avoid taking direction readings 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 readings are impossible while in a train, boat, air plane, etc.
•Accurate readings 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 bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should 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 the procedure under “To
perform bidirectional calibration” (page E-30).
