Calibrating altitude indication
About altitude indication
This watch measures atmospheric pressure with a specialized sensor and calculates
altitude by applying the standard atmosphere model (set by ICAO, International
Civil Aviation Organization) used for altitude measurement of civil aircrafts.
The standard atmosphere model sets a theoretical atmosphere and how pressure,
temperature, density and viscosity vary accompanying with change of altitude in it.
Therefore, expected altitude may significantly differ from actual one when the
weather changes drastically such as in climbing.
You can calibrate altitude indication by entering altitude already known.
•You can calibrate the value in the range of ±1 000 m of currently measured
altitude.

About compass indication
This watch measures earth magnetism directly with the built-in magnetic sensor
for compass indication.
Earth magnetism measurement is apt to be easily affected by environmental
conditions near a magnet or thing emitting strong electromagnetic waves.
In addition, generally, the north which a compass points to (magnetic north)
is different from that on a map (true north). You can determine the true north
through the compass function by calibration and adjustment of the watch.
You can use 2 methods to calibrate the compass of this watch: 2 point correction
(page 34) and declination correction (page 40).
Take care not to try to find compass direction around things generating strong
magnetic fields same as using an ordinary compass.
Avoid such an environment also while calibrating the compass.
32
Calibrating compass indication
About 2 point correction
2 point correction adjust the watch’s status according to the surrounding
environment.
Use it when temperature drastically changed or the watch itself may be magnetized.
2 point correction is more effective if you do it before using the compass.

About declination correction
Due to physical characteristics of the Earth as an astronomical body, the magnetic
north and true north as indicated on a map are different. The difference is called
“declination”. Declination varies by location.

Calibrating compass indication
Declination correction is a correction method to adjust the compass of the watch
to indicate true north as indicated on a map by setting the declination value of the
location where you wants to find compass direction on the watch previously.
On this watch, declination of 0° to 59° east and west can be set by 1°.
You can use the results of geomagnetism survey published by governmental or
other organizations.

Eco-Drive (solar-powered) watch handling precautions
<Replacement of Rechargeable Cell>
•This watch utilizes a special rechargeable cell that does not require periodical replacement.
However power consumption may increase after using the watch for a number of years due
to wear of internal components and deterioration of oils. This may cause stored power to be
depleted at a faster rate. For optimal performance, we recommend having your watch inspected
every 2-3 years for proper operation and condition check.
WARNING
Handling of Rechargeable Cell
•The rechargeable cell should never be removed from the watch.
If for any reason it becomes necessary to remove the rechargeable cell from the watch, keep out
of the reach of children to prevent accidental swallowing.
If the rechargeable cell is accidentally swallowed, consult a doctor immediately.
•Do not dispose of the rechargeable cell with ordinary garbage. Please follow the instructions of
your municipality regarding collection of batteries to prevent the risk of fire or environmental
contamination.

Eco-Drive (solar-powered) watch handling precautions
WARNING
Use Only the Specified Battery
•Never use a battery other than the rechargeable cell specified for use in this watch.
Although the watch structure is designed so that it will not operate when another type of
battery is installed, if a conventional watch battery or other type of battery is installed in the
watch and the watch is recharged, there is the risk of overcharging which may cause the battery
to rupture.
This can cause damage to the watch and injury to the wearer.
When replacing the rechargeable cell, always make sure to use the designated rechargeable cell.

Water resistance
•Non-water resistant models are not designed to come into contact with any moisture. Take care
not to expose a watch with this rating to any type of moisture.
•Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for
occasional accidental splashing.
•Upgraded water-resistance for daily use (to 5 atmospheres) means that the watch may be worn
while swimming, but is not to worn while skin diving.
•Upgraded water-resistance for daily use (to 10/20 atmospheres) means that the watch may be
worn while skin diving, but not while scuba or saturated diving using helium gas.
64
Precautionary items and usage limitations
CAUTION
To Avoid Injury
•Be particularly careful when wearing your watch while holding a small child, to avoid injury.
•Be particularly careful when engaged in strenuous exercise or work, to avoid injury to yourself
and others.
•Do not wear your watch while in a sauna or other location where your watch may become
excessively hot, since there is the risk of burns.
•Be careful when putting on and taking off your watch, since there is a risk of damaging your
fingernails, depending on the manner in which the band is fastened.
•Take off your watch before going to bed.
65
Precautionary items and usage limitations
CAUTION
Precautions
•Always use the watch with the crown pushed in (normal position). If the crown is of the screw
lock-type, make sure it is securely locked.
•Do not operate the crown or any push buttons when the watch is wet. Water may enter the
watch causing damage to vital components.
•If water enters the watch or the watch fogs up and does not clear up even after a long time,
consult your dealer or customer support center for inspection and/or repair.
•Even if your watch has a high level of water resistance, please be careful of the following.
•If your watch is immersed in sea water, rinse thoroughly with fresh water and wipe with a
dry cloth.
•Do not pour water from a tap directly onto your watch.
•Take off your watch before taking a bath.
•If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in
for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, push
button, etc.) may come off.
66
Precautionary items and usage limitations
CAUTION
When Wearing Your Watch
<Band>
•Leather bands and rubber (urethane) bands will deteriorate over time due to perspiration dirt.
Because of the natural materials, leather band will be worn, deformed, and discolored over
time. It is recommended to replace the band periodically.
•The durability of a leather band may be affected when wet (fading, peeling of adhesive), owing
to the properties of the material. Moreover, wet leather may cause a rash.
•Do not stain a leather band with substances containing volatile materials, bleach, alcohol
(including cosmetics). Discoloration and premature aging may be occurred. Ultraviolet light
such as direct sunlight may cause discoloration or deformation.
•It is recommended to take off the watch if it gets wet, even if the watch itself is water-resistant.
•Do not wear the band too tightly. Try to leave enough space between the band and your skin to
allow adequate ventilation.
•The rubber (urethane) band may be stained by dyes or soil present in or on clothing or other
accessories. Since these stains may not be removable, caution is required when wearing your
watch with items that tend to easily transfer color (articles of clothing, purses, etc.). In addition,
the band may be deteriorated by solvents or moisture in the air. Replace with a new one when it
has lost elasticity or become cracked.
67
Precautionary items and usage limitations
CAUTION
When Wearing Your Watch (continued)
•Please request adjustment or repair of the band in the following cases:
•You notice an abnormality with the band due to corrosion.
•The pin of the band is protruding.
•We recommend seeking the assistance of an experienced watch technician for sizing of your
watch. If adjustment is not done correctly, the bracelet may unexpectedly become detached
leading to loss of your watch or injury.
Consult your nearest authorized Citizen service center.
<Temperature>
•The watch may stop or the function of the watch may be impaired in extremely high or low
temperature. Do not use the watch in places where the temperature is outside the operating
temperature range as stated in the specifications.
<Magnetism>
•Analog quartz watches are powered by a step motor that uses a magnet. Subjecting the watch to
strong magnetism from the outside can cause the motor to operate improperly and prevent the
watch from keeping time accurately.
Do not allow the watch to come into close proximity to magnetic health devices (magnetic
necklaces, magnetic elastic bands, etc.) or the magnets used in the latches of refrigerator doors,
clasps used in handbags, the speaker of a cell phone, electromagnetic cooking devices and so on.
68
Precautionary items and usage limitations
<Strong Shock>
•Avoid dropping the watch or subjecting it to other strong impact. It may cause malfunctions
and/or performance deterioration as well as damage to the case and bracelet.
<Static Electricity>
•The integrated circuits (IC) used in quartz watches are sensitive to static electricity. Please note
the watch may operate erratically or not at all if exposed to intense static electricity.
<Chemicals, Corrosive Gasses and Mercury>
•If paint thinner, benzene or other solvents or products containing these solvents (including
gasoline, nail-polish remover, cresol, bathroom cleaners and adhesives, water repellent, etc.)
are allowed to come into contact with the watch, they may discolor, dissolve or crack the
materials. Be careful when handling these chemicals. Contact with mercury such as that used
in thermometers may also cause discoloration of the band and case.
<Protective Stickers>
•Be sure to remove any protective stickers that may be on your watch (case back, band, clasp,
etc.). Otherwise, perspiration or moisture may enter the gaps between the protective stickers
and the parts, which may result in a skin rash and/or corrosion of the metal parts.
69
Precautionary items and usage limitations
CAUTION
Always Keep Your Watch Clean
•Rotate the crown while it is pressed in fully and press the buttons periodically so they do not
become stuck due to accumulations of foreign matter.
•The case and band of the watch come into direct contact with the skin. Corrosion of the metal
or accumulated foreign matter may result in black residue coming from the bracelet when
exposed to moisture or perspiration. Be sure to keep your watch clean at all times.
•Be sure to periodically clean the bracelet and case of your watch to remove accumulated dirt
and foreign matter. In rare circumstances, accumulated dirt, foreign matter may cause irritation
with the skin. If you notice this, discontinue wearing the watch and consult your physician.
•Be sure to periodically clean foreign matter and accumulated materials from the metal band,
synthetic rubber strap (polyurethane) and/or metal case using a soft brush and mild soap. Be
careful not to allow moisture on the case if your watch is not water resistant.
•Leather bands may become discolored by perspiration or dirt. Always keep your leather band
clean by wiping with a dry cloth.
70
Precautionary items and usage limitations
Caring for Your Watch
•Wipe any dirt or moisture such as perspiration from the case and crystal with a soft cloth.
•For metallic, plastic or synthetic rubber (polyurethane) band, clean it with soap and a soft
toothbrush. Be sure to thoroughly rinse the band after cleaning to remove any soap residue.
•For a leather band, wipe off dirt using a dry cloth.
•If you will not be using your watch for an extended period of time, carefully wipe off any
perspiration, dirt or moisture and store in a proper location, avoiding locations subject to
excessively high or low temperatures and high humidity.
<When Luminous Paint is used for your watch>
The paint on the dial and hands helps you with reading the time in a dark place. The luminous
paint stores light (daylight or artificial light) and glows in a dark place.
It is free from any radioactive substance or any other material harmful to a human body or
environment.
•The light emission will appear bright at first and then diminish as time passes.
•The duration of the light (“glow”) will vary depending on the brightness, types of and
distance from a light source, exposure time, and the amount of the paint.
•The paint may not glow and/or may dissipate quickly if exposure to light was not sufficient.
