9. EL INTERNAL ILLUMINATION FUNCTION
What is EL?
EL is the abbreviation for electroluminescence. It refers
to the phenomenom in which light is emitted when a
voltage is applied to a certain type of material. This
watch incorporates an EL substance in its panel and
uses that substance to emit light.
Illumination Method
Press button C or D to turn on the EL illumination.
* When the watch is returned to the stopwatch
mode after switching to a different mode while
the stopwatch is measuring time, the watch will
return to measurement as it was prior to switching
to the other mode. However, exceptions to this
are as follows;
When the stopwatch is measuring split time,
the watch will return to stop watch
measurement.
When the stopwatch is in split mode, the
watch will enter the stop mode.
* The watch automatically returns to the normal
display (on state) when none of the watch
buttons are pressed for 1 minute or more or
when in the alarm correction mode.
* In addition, the watch automatically returns to
the normal display time when none of the watch
buttons are pressed for 1 minute or more when
in the normal alarm display.
* When the time is displayed using a 12-hour
clock, since the alarm time also uses a 12-hour
clock, pay attention to the AM and PM when
setting the alarm time.

11. PRECAUTIONS
CAUTION: Water-resistance Performance
There are several types of water resistant watches, as
shown in the following table. For correct use within the
design limits of the watch, confirm the level of water
resistance of your watch, as indicated on the dial and
case, and consult the table.
Water-resistance for daily use (to 3 atmospheres):
This type of watch is water-resistant to minor exposure
to water. For example, you may wear the watch while
washing your face, however it is not designed for use
underwater.
Upgraded water-resistance for daily use (to 5
atmospheres): This type of watch is water-resistant to
moderate exposure to water. You may wear the watch
while swimming, however it is not designed for skin
diving.
Upgraded water-resistance for daily use (to 10/20
atmospheres): This type of watch may be used for
skin diving; however, it is not designed for scuba or
saturated diving using helium gas.
CAUTION
• Do not operate the buttons with wet fingers or when
the watch is wet. Water may enter the watch and
compromise the watches water-resistance.
• If the watch is used in seawater, rinse with fresh
water afterward and wipe dry with a cloth.
• If moisture has entered the watch, or the inside of the
crystal is fogged up and does not become clear
within a day, immediately take the watch to your
dealer or Citizen Service Centre for repair. Leaving
the watch in such a state will allow corrosion to form
inside.
• If seawater enters the watch, place the watch in a box
or a plastic bag and immediately take it in for repair.
Otherwise, pressure inside the watch will increase,
and parts (crystal, buttons, etc.) may come off.
CAUTION: Keep your watch clean.
• Dust and dirt tend to be deposited in gaps in the back
of the case and band.
Deposited dust and dirt may cause corrosion and soil
your clothing. Clean the watch occasionally.

Cleaning the Watch
• Use a soft cloth to wipe off dirt, perspiration and
water from the case and crystal.
• Use a soft, dry cloth to wipe off perspiration and dirt
from the leather band.
• To clean a metal, plastic or rubber watchband, wash
away dirt with mild soap and water. Use a soft brush
to remove dust and dirt jammed in the gaps in the
metal band. If your watch is not water resistant, take
it to your dealer.
NOTE: Avoid using solvents (thinner, benzine, etc.) as
they mar the finish.
WARNING: Handling of the battery
• Keep out of reach of small children. If a child swallows
the battery contact a physician immediately.
CAUTION: Replacing the battery
• For replacement of the battery, take your watch to
your Citizen Service Centre.
• Replace the battery as soon as possible if the service
life of the battery has expired. Leaving a depleted
battery in the watch may result in leakage, which can
damage the watch severely.
CAUTION: Operating environment
• Use the watch within the operating-temperature
range specified in the instruction manual.
Using the watch where temperatures are outside the
specified range, may result in deterioration of the
functions or even stoppage of the watch.
• Do not use the watch in places where it is exposed to
high temperature, such as in a sauna. Doing so may
result in skin burn.
• Do not leave the watch in a place where it is exposed
to high temperature, such as a glove compartment or
dash-board of a car.
Doing so may result in deterioration of the watch,
such as deformation of plastic parts.
• Do not place the watch close to a magnet.
Timekeeping will become innacurate if you place the
watch close to magnetic health equipment such as a
magnetic necklace or the magnetic latch of a
refrigerator door or handbag clasp or the earphone of
a mobile phone. If this has occured, move the watch
away from the magnet and reset the time.
• Do NOT place the watch close to household
appliances that generate static electricity.
Timekeeping may become innaccurate if the watch is
exposed to strong static electricity, such as emitted
from a TV screen.
• Do NOT subject the watch to strong shocks such as
dropping it onto a hard floor.
• Avoid using the watch in an environment where it
may be exposed to chemicals or corrosive gases.
If solvents. such as thinner and benzine, or
substances containing such solvents come in contact
with the watch, discolouration, melting, cracking, etc.
may result.
If the watch comes into contact with mercury used in
thermometers, the case, band or other parts may
become discoloured.
