Operation Guide 5611
E-64
Low Battery Power
x Low battery power is indicated by large timekeeping error, by dim display contents,
or by a blank display.
x Operation while battery power is low can result in malfunction. Replace the
batteries as soon as possible.
E-63
Battery Replacement
x Leave battery replacement up to your original retailer or authorized CASIO service
center.
x Have the batteries replaced only with the type specified in the User’s Guide. Use of
a different battery type can cause malfunction.
x When replacing the batteries, also request a check for proper water resistance.
x Ornamental resin components may become worn, cracked, or bent over
time when subjected to normal daily use. Note that if cracking or any other
abnormality indicating possible damage is noticed in a watch submitted for battery
replacement, your watch will be returned with an explanation of the abnormality,
without the requested servicing being performed.
Initial Batteries
x The batteries that come loaded in your watch when you purchase it are used for
function and performance testing at the factory.
x Test batteries may go dead quicker than the normally rated battery life as noted in
the User’s Guide. Note that you will be charged for replacement of these batteries,
even if replacement is required within your watch’s warranty period.
E-62
x Rust can cause sharp areas on metal components and can cause band pins to fly
out of position or to fall out. If you ever notice any abnormality immediately stop
using your watch and take it to your original retailer or to an authorized CASIO
service center.
x Even if the surface of the metal appears clean, sweat and rust in crevasses can
soil the sleeves of clothing, cause skin irritation, and even interfere with watch
performance.
Premature Wear
x Leaving sweat or water on a resin band or bezel, or storing your watch an area
subject to high moisture can lead to premature wear, cuts, and breaks.
Skin Irritation
x Individuals with sensitive skin or in poor physical condition may experience skin
irritation when wearing a watch. Such individuals should keep their leather band
or resin band particularly clean. Should you ever experience a rash or other skin
irritation, immediately remove your watch and contact a skin care professional.
E-61
x For a resin band, wash with water and then wipe dry with a soft cloth. Note that
sometimes a smudge like pattern may appear on the surface of a resin band. This
will not have any effect on your skin or clothing. Wipe with a cloth to remove the
smudge pattern.
x Clean water and sweat from a leather band by wiping with a soft cloth.
x Not operating a watch crown, buttons, or rotary bezel could lead to later problems
with their operation. Periodically rotate the crown and rotary bezel, and press
buttons to maintain proper operation.
Dangers of Poor Watch Care
Rust
x Though the metal steel used for your watch is highly rust-resistant, rust can form if
your watch is not cleaned after it becomes dirty.
– Dirt on your watch can make it impossible for oxygen to come into contact with
the metal, which can lead to breakdown of the oxidization layer on the metal
surface and the formation of rust.

User Maintenance
Caring for Your Watch
Remember that you wear your watch next to your skin, just like a piece of clothing.
To ensure your watch performs at the level for which it is designed, keep it clean by
frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat,
water and other foreign matter.
x Whenever your watch is exposed to sea water or mud, rinse it off with clean fresh
water.
x For a metal band or a resin band with metal parts, use a soft toothbrush or similar
tool to scrub the band with a weak solution of water and a mild neutral detergent,
or with soapy water. Next, rinse with water to remove all remaining detergent and
then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch
case with kitchen plastic wrap so it does not come into contact with the detergent
or soap.
