Handling Batteries
Whenever removing the button type battery that powers the

swallowed accidentally. Special care is required where young
children are present.
Keep batteries out of the reach of small children. Should a battery
ever be swallowed accidentally, contact a physician immediately.
Caution!
Skin Irritation
Should you ever experience any skin irritation or any other
abnormality while wearing the chest strap, immediately take it off.
Since the watch and the chest strap come into direct contact with
the skin, the following conditions may cause irritation of the skin.
• When a wearer is allergic to metal or leather
• When the watch or chest strap is rusty dirty, sweaty, etc.
• When the wearer is in poor physical condition
• Tightening the chest strap too tightly can cause you to sweat,
and can make it hard for air to pass under the strap, which can
lead to skin irritation. Do not over-tighten the chest strap.
• Should you ever notice any abnormality, immediately stop
using the product and consult a physician.
Caring for This Product
To clean the product, wipe it with a soft, dry cloth, or with a cloth
that has been moistened in weak solution of water and a mild
neutral detergent. Wring out all excess liquid from the cloth
before wiping. Never use thinner, benzene, alcohol, or any other
volatile agent to clean the product.
Use of the Product
When putting on or taking off the chest strap, make sure you do
not twist, bend, or stretch it excessively.
Take care not to drop the product or otherwise subject it to strong
impact.
To avoid unexpected accidents, always check around you to
ensure you are in a safe place before looking at the display of the
watch. Looking at the watch while marathoning or jogging on the
open road, while riding a bicycle, or operating a motor vehicle
can lead to accidents.

Should the watch stop running, have the battery replaced as
soon as possible.
Take care to avoid breaking your fingernails when fastening and
unfastening the band. Particular care is required by people with
long fingernails.
To avoid skin irritation due to unexpected injury or allergy, do not
wear the watch while sleeping.
When picking up or otherwise coming into contact with a child,
remove the watch from your wrist to avoid injury to the child or
causing irritation of the child’s skin.
Never try to take the watch apart!
Never try to take the watch apart. Doing so creates the risk of
personal injury and malfunction of the watch.
Battery Replacement
When the watch’s battery is replaced, foreign matter adhering to
contact surfaces can cause a loss of water resistance. In order to
ensure water resistance is maintained and the watch performs at
the level for which it is designed, make sure you always request
battery replacement from your dealer or CASIO distributor.
Keep backup copies of data!
Make sure you always keep separate written copies of important
data to protect against its loss. Malfunction, repair, and battery
replacement can cause memory contents to be deleted.
