Notes on safety when using the DUALSHOCK ® 4 Wireless
Controller*
• Do not handle damaged or leaking lithium-ion batteries. If
the internal battery fluid leaks, stop using the product
immediately and contact technical support for assistance. If
the fluid gets on to your clothes, skin or into your eyes,
immediately rinse the affected area with clean water and
consult your physician. The battery fluid can cause
blindness.
• Stop using the system immediately if you begin to feel tired
or if you experience discomfort or pain in your hands or
arms while operating the wireless controller. If the
condition persists, consult a doctor.
• The vibration function of the wireless controller can
aggravate injuries. Do not use the vibration function if you
have any ailment or injury to the bones, joints or muscles of
your hands or arms. If you have an ailment or an injury, do
not use the wireless controller to play software titles that
contain the vibration function unless you first disable this
function.
• Avoid prolonged use of the wireless controller. Take a break
at about 30-minute intervals.
• Note that some software titles enable the vibration function
by default. To disable the vibration function, Select
(Settings) [Devices]
remove the checkmark from [Enable Vibration].
• When using the motion sensor function of the wireless
controller, be cautious of the following points. If the
controller hits a person or object, this may cause accidental
injury or damage.
– Before using, check that there is plenty of space around
you.
– When using the controller, grip it firmly to make sure it
cannot slip out of your hand.
– If using a controller that is connected to the PS4™ system
with a USB cable, make sure there is enough space for the
cable so that the cable will not hit a person or object. Also,
take care to avoid pulling the cable out of the PS4™
system while using the controller.
– Some PlayStation ® , PlayStation ® 2 and PlayStation ® 3
system peripherals such as the analog controller
(DUALSHOCK ® ), the analog controller (DUALSHOCK ® 2)
and the DUALSHOCK ® 3 Wireless Controller are not
compatible with the PS4™ system.
• Do not stare at the light bar on the controller when it is
blinking. If you experience discomfort or pain anywhere in
or on your body from light stimulation, discontinue use
immediately.
• Charge in an environment where the temperature range is
between 10 °C - 30 °C. Charging may not be as effective
when performed in other environments.
• The battery has a limited lifespan. Battery duration will
gradually decrease with repeated usage and age. Battery
life also varies depending on the storage method, usage
state, environment and other factors.
• When the wireless controller is not used for an extended
period of time, it is recommended that you fully charge it at
least once a year in order to maintain battery functionality.
* These notes may also apply to other controllers.
