D. EL (ELECTROLUMINESCENCE)
ILLUMINATION
EL refers to the emission of light by a phosphorescent
substance under the influence of an applied voltage.
The panel of this watch provides illumination by
electroluminescence.
Illumination method
The El panel will be illuminated under the following
conditions.
1. When pressing 
Rbutton in time mode, or
calendar mode.
2. When displaying stop or split time state in
chronograph mode.
Characteristics and replacement of the EL
(electroluminescence) panel
The EL (electroluminescence) panel has the
following properties.
• When the battery voltage drops, the brightness
(intensity) also drops.
• It is adversely affected by humidity.
If any water enters inside the watch by accident,
promptly request repair.
• The EL panel has a finite life span.
The brightness (intensity) gradually drops in
proportion to the total number of hours of use
(light emission).
If the display appears dark or is hard to see when
the EL panel is lit, ask either the store where you
purchased the product or your nearest CITIZEN
Service Centre to replace the EL panel. This repair
will be done for a fee.

H. USING THE REGISTER-RING
• The register-ring gives you a convenient way to

<Calculating the elapsed time>
• Align the minute hand with the register-ring zero
mark ( ). The elapsed minutes since the ring was
set can now be easily calculated by comparing the
positions of the zero mark and the minute hand.
Example:
1. Current time is 10:10.
Align the zero mark ( ) to
the 25 minute mark on the
dial.
2. The watch is next checked at
10:40. To determine the
2. elapsed time, read the number of the register-ring
at the minute hand position. The elapsed time is
30 minutes (fig. 1).
<Calculating the remaining time>
• Align the register ring zero mark ( ) with the
target time and use the ring’s calibrations to
calculate the remaining time.
Example:
1. The target time is 10:25.
Set the register-ring zero
mark ( ) to the 25 minute
mark on dial.
2. If the current time is 10:10,
the remaining time is
2. 15 minutes (60 minus 45) as calculated from the
register-ring (fig. 2).

I. PRECAUTIONS
Water Resistance
• To prevent water coming into contact with the
internal mechanism of the watch, the crown should
under no circumstances be pulled out while the
watch is wet.
• If watches designed for sports or working in the
water are exposed to salt water or significant
amounts of sweat, they should be rinsed in fresh
water and dried thoroughly.
• Exposure to water may affect the durability of
some types of leather bands.
• Because the internal watch parts may hold some
moisture, if the external temperature is lower than
that inside the watch, the glass covering the watch
face may fog up.
If this fogging up is only temporary it poses no
problem, however, if it persists over a long period
of time you should discuss the matter with a
salesperson at the shop where you purchased the
watch or at a Citizen Service Centre.
Temperature
Avoid exposing the watch to direct sunlight or
leaving it in extremely hot or cold locations for a
long period of time.
• This will cause malfunctioning and shorten the life
of the battery.
• This may cause your watch to gain or lose time
and affect its other functions.
Shock
• This watch will withstand the bumps and jars
normally incurred in daily use and while playing
such non-contact sports as golf and catchball.
• Dropping the watch on the floor or otherwise
imparting severe shock to it may cause
malfunctioning or damage.
Static Electricity
• The integrated circuits used in the watch are
sensitive to static electricity. If exposed to intense
static electricity, the watch’s display may lose its
accuracy.
Chemicals and Gases
Avoid wearing the watch in the presence of strong
chemicals or gases. If the watch comes in contact
with such solvents as thinner and benzine or
products containing materials such as gasoline, nail
polish, detergent or adhesive, its components may
discolour,,dissolve or crack. Be especially careful to
avoid chemicals. The watchcase or band may
discolour if they come in contact with mercury from
a broken thermometer or the equipment.
KeepYour Watch Clean
Wipe off soil and moisture from the glass with a
soft, absorbent cloth. If you wear the watch when
the back side of the case and watchband is soiled
they may cause a skin rash as they come in direct
contact with your skin. Keep your watch clean also
to avoid staining your cuffs.
Battery
• The battery is a monitor battery that has been
factory-installed. For this reason it may wear out
after purchase before the specified battery life
(about 3 years) has elapsed.
• Be sure to keep the battery out of the reach of
infants and small children. Should accidental
ingestion occur, consult a doctor immediately.
