CAUTION: Keep your watch clean.
• Dust and dirt tend to be deposited in gaps in the
back of the case or 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 perspiration and dirt
from 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 may mar the finish.
WARNING: Handling of the battery
• Keep the battery out of the 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 dealer or 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
functions or even stoppage of the watch.
• Do NOT use the watch in a place where it is
exposed to high temperature, such as a sauna.
Doing so may result in a skin burn.
• Do NOT leave the watch in a place where it is
exposed to high temperature, such as the 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 inaccurate if you place
the watch close to magnetic health equipment
such as a magnetic necklace or a magnetic latch
of a refrigerator door or handbag clasp or the
earphone of a mobile phone. If this has occurred,
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 inaccurate 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 in
contact with mercury used in thermometers, the
case, band or other parts may become
discoloured.
