GENERAL GUIDE
BACKLIGHT
The backlight uses an EL (electro-luminescent)
panel that causes the entire display to glow for
easy reading in the dark. The watch’s auto light
switchautomatically turns on the backlightwhen
you angle the watch towards your face.

REFERENCE
This section contains more detailed and technical information about watch
operation.It also containsimportant precautions andnotesabout the various
features and functions of this watch.
Warning Indicators
Warningindicatorsappearwhenever any of the conditions described below
occur. Appearance of a warning indicator causes any measurement
operation that is currently underway to stop. Warning indicators appear in
the upper display, and this causes --- to replace any direction or
temperature values on the display.
•There may be cause where the ERR or BAT message is cleared
once you change modes. In this case, you can continue using the watch
normally unless the error warning message reappears.
•Whenever there is a sensor malfunction, be sure to take the watch to an
authorized CASIO distributor or service center as soon as possible.
Abnormal Magnetic Field Indicator
This indicator appears whenever the watch has a problem
obtaining a correct direction reading. This condition could
indicate that the watch is within a very high magnetic field,
and so you should try moving to another location. Also,
see “Digital Compass Precautions” for further information
on conditions that cause errors.
Low Battery Indicator
This message indicates that batteries power is too low to
perform the measurement. It appears whenever batteries
power drops below a certain level, or when you try to use
thiswatch under very cold conditions (below about –10°C).
If the BAT message appears because of use under cold conditions, it
shouldclear (and normal operation should return) after thewatchisbrought
back to normal temperature.
If batteries power is low (indicated BAT appears under normal
temperatures),you should have the batteries replaced as soon as possible.
Note that replacement of the batteries causes all memory contents to be
cleared.
Sensor Malfunction Indicator
This message indicates malfunction of sensor circuitry.
Whenever a sensor malfunction initially occurs, the ERR
messages flashes on the display. Note that calibrating the
DigitalCompass may cause theERR messagetoappear.
In this case, the message does not indicate sensor
malfunction, and should be corrected if you re-calibrate
the Digital Compass.
Auto Return Operations
•After you perform an operation in any mode, pressing Dreturns to the
Timekeeping Mode.
•If you leave a screen with flashing digits on the display for two or three
minuteswithoutperforming any operation, the watch automatically saves
anything you have input up to that point and exits the setting screen.
Data and Setting Scrolling
The Band Cbuttons are used in various modes and screens to scroll
through data on the display. In most cases, holding down these buttons
during a scroll operation scrolls through the data at high speed.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is also applied in the Navigation, World Time, andAlarm Modes.
Backlight Precautions
•The electro-luminescent panel loses illuminating power after very long
use.
•The illumination provided by the backlight may be hard to see when
viewed under direct sunlight.
•Thewatchwillemit an audible sound whenever the display is illuminated.
This is caused by a transformer 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.
Auto light switch precautions
•Avoid wearing the watch on the inside of your wrist. Doing so causes the
auto light switch to operate when it is not needed, which shortens battery
life.
•The backlight turns off in about two seconds, even if you keep the watch
pointed towards your face.
•Thebacklight may notlightif the faceofthe watch ismorethan 15 degrees
off the parallel as shown below. Make sure that the back of your hand is
parallel to the ground.
•Static electricity or magnetic force can interfere with proper operation of
the auto light switch. If the backlight does not light, 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.
•Undercertain conditions thebacklightmay not lightuntilabout one second
or less after turn the face of the watch towards you. This does not
necessarily indicate malfunction of the backlight.

World Time Mode
•The seconds count of the World Time is synchronized with the seconds
sound of the Timekeeping Mode.
•GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC) data.
•Average monthly temperature values displayed by this watch are based
on the “WORLD CLIMATE TABLE” published by the Japanese
government’s Meteorological Agency.
Temperature and Direction Reading Precautions
•The direction and temperature reading operation is automatically
interrupted whenever an alarm or Hourly Time Signal sounds. If this
happens, start the reading operation again from the beginning.
•Taking a direction reading while the watch is not horizontal (in relation to
the horizon) can result in large error.
•Ifthe Navigation Mode memory area you select tostoreareading already
contains data, the data of the new reading replaces the existing data.
Digital Compass Precautions
Thiswatch features abuilt-inmagnetic bearing sensorthatdetects terrestrial
magnetism.This meansthatnorth indicated by this watchismagneticnorth,
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
closerto either of the magnetic poles.Youshouldalso remember that some
maps indicate true north (instead of magnetic north), and so you should
make allowances when using such maps with this watch.
Direction Values The direction values displayed by this watch
represent the clockwise angle formed between
magnetic north (which is 0 degrees) and the
directionthat the 12 o’clock positionofthewatch
is pointing.

Location
•Taking a direction reading when you are near a source of strong
magnetismcan causelargeerrors in readings.Because of this,youshould
avoid taking direction readings while in the vicinity of the following types
ofobjects: permanent magnets(magneticnecklaces, etc.), concentrations
of metal (metal doors, lockers, etc.), high tension wires, aerial wires,
household appliances (TVs, personal computers, washing machines,
freezers, etc.).
•Accuratedirection readings are impossible while in a train, boat, airplane,
etc.
•Accurate readings are also impossible indoors, especially inside ferro-
concrete structures. This is because the metal framework of such
structures picks up magnetism from appliances, etc.
Storage
•Theprecision of the bearing sensor may deteriorateifthe watch becomes
magnetized.Becauseofthis, you should be sure to store the watch away
from magnets or any other sources of strong magnetism, including:
permanentmagnets (magnetic necklaces,etc.) and householdappliances
(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 Bearing
Sensor” below.
Calibrating the Bearing Sensor
Whenever you suspect that direction readings produced by the watch are
wrong, you should calibrate it. You can use either one of two calibration
procedures: bidirectional calibration or northerly calibration .
Usebidirectionalcalibrationwhenyou want to take readings 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
coulduse this calibrationprocedure,for example, to setthewatch 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.
•The more correctly you perform bidirectional calibration, the better the
accuracyof the bearing sensor readouts.Youshould perform bidirectional
calibrationwhenever youchangeenvironments whereyouuse thebearing
sensor, and whenever you feel that the bearing sensor is producing
incorrect readings.
To perform bidirectional calibration
1. While in the Navigation Mode, hold down
Auntil the upper display changes to show
-1-.
•At this time, the magnetic north pointer
flashesat the 12 o’clock position to indicate
that the watch is ready to calibrate the first
direction.
2. Placethewatch on a level surface facing any
direction you want, and press Cto calibrate
the first direction.
•Whenthe calibration procedureiscomplete, the messageOK appears
in the upper display. This soon changes to -2- and the magnetic
northpointerflashesatthe6o’clockpositiontoindicatethatthewatch
is ready for the second direction.
3. Rotate the watch 180 degrees.
4. Press Cagain to calibrate the second direction.
•Whenthe calibration procedureiscomplete, the messageOK appears
inthe upper display.Aftera short while, the watch automaticallyreturns
to the Navigation Mode’s initial screen.
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 during the one or two seconds (from the point
you press Cup 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, which means you have to 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 taking direction readings. 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 Navigation Mode, hold down
Auntil the upper display changes to show
-1-.
2. Press Dto start the northerly calibration
procedure.
•At this time, the indicator 0°appears in
the upper display.
3. Place the watch on a level surface, and
positionit so that its 12 o’clock positionpoints
north (as measured with another compass).

to the Navigation Mode’s initial screen.
Questions & Answers About Direction Readings
Question: What causes incorrect direction readings?
Answer:
•Incorrect bidirectional calibration. Perform bidirectional calibration.
Remember that bidirectional calibration is required whenever batteries
are replaced.
•Nearby source of strong magnetism, such as a household appliance, a
large steel bridge, a steel beam, overhead wires, etc., or an attempt to
perform direction measurement on a train, boat, etc. Move away from
large metal objects and try again. Note that digital compass operation
cannot be performed inside a train, boat, etc.
Question:What causes different direction readings to produce
different results at the same location?
Answer: Magnetism generated by nearby high-tension wires are
interfering with detection of terrestrial magnetism. Move away
from the high-tension wires and try again.
Question:What does it mean when --- appears in place of a
direction value?
Answer: Thisis the abnormalmagneticfield indicator. It meansthatstrong
magnetism is being generated nearby. Move away from the
source of strong magnetism and try again.
Question:Whyam I having problems takingdirection readingsindoors?
Answer: A TV, personal computer, speakers, or some other object is
interferingwithterrestrialmagnetism readings. Move away from
the object causing the interference or take the direction reading
outdoors.Indoor taking direction readingsareparticularly difficult
inside ferro-concrete structures. Remember that you will not be
able to take direction readings inside of trains, airplanes, etc.

1869-6
Question:What do the numbers on the watch mean?
Answer: The face of this watch is marked with
values that increase in a counterclockwise
direction. These values represent degrees.
When you take a direction reading, you can
usethese values tofindout how manydegrees
the12 o’clock positionofthis watch differsfrom
magnetic north.
Forexample, when the Magnetic North pointer
ispointing at “90” on thewatch’sface, it means
that the 12 o’clock position is 90 degrees from
magnetic north (which means that 12 o’clock
is pointing due east).
