Casio YC-400 User Manual

Safety Precautions

• Never carry or store the battery 

together with conductive objects 
(necklaces, pencil lead, etc.)

• Never try to take the battery apart 

or modify it, never pierce it or 
subject it to strong impact (by hitting 
it with a hammer or stepping on it), 
and never apply solder to the 
battery. Never put the battery inside 
of a microwave oven, dryer, high-
pressure container, etc.

Should a battery start to leak, emit a 
strange odor, emit heat, change color, 
change shape, or exhibit any other 
abnormal behavior while it is being 
used, charged, or stored, immediately 
remove it from the camera or charger 
unit and keep it away from fire.

Never use or leave the battery in 
direct sunlight, inside of a closed 
vehicle on a hot day, or in any other 
area where it is very hot. Such 
conditions create the risk of damage 
to the battery, reduction of its 
performance, and shortening of its life.

●

Misuse of the AC adaptor creates the 
risk of fire and electric shock. Make 
sure that you always observe the 
following precautions.

• Unplug the AC adaptor before 

leaving on a trip or otherwise 
leaving it unattended for a long 
period. 

• Unplug the AC adaptor at least 

once a year and clean any dust 
built up around the prongs of the 
plug.

●

Stop charging after the stipulated 
charging time, even if the battery is 
not fully charged. Charging too long 
creates the risk of battery overheating, 
fire, and explosion.

Battery fluid getting into your eyes 
creates the risk of eye damage. 
Immediately flush your eyes with 
water and then contact your physician.

Be sure to read all of the applicable 
camera and charger unit user 
documentation before using or 
charging the battery.

Keep the battery out of the reach of 
small children. Even while using the 
battery, take steps to ensure that 
children to not remove it from the 
camera or charger unit.

Fluid leaking from the battery and 
getting onto your skin or clothing 
creates the risk of skin inflammation. 
Immediately rinse the area with water.

●

Attach only the specified bundled 
accessories to the connectors of the 
stand and camera. Connecting 
anything else creates the risk of fire 
and electric shock.

●

Never place or leave the stand and 
camera on a high shelf, or on an 
unstable or uneven surface. The stand 
and camera can fall from such a 
location, creating the risk of personal 
injury.

• Never cover the AC 

adaptor with a blanket 
while it is in use or 
locate it next to a 
heater. Such conditions 
can interfere with heat 
radiation, and cause 
heat to build up in the 
area of the AC adaptor.

• Never pull on the power 

cord when unplugging 
the AC adaptor. Grasp 
the plug unit. 

• Insert the plug into the 

power outlet as far as it 
will go.
