Radio waves
Radio waves may affect electronic equipment or medical
devices (for example, pacemakers), which may cause
malfunctions and possible injuries.
ˎ If you use a pacemaker or other medical device, consult your
physician or the manufacturer of your medical device before
using the wireless networking feature (Bluetooth ® and
wireless LAN).
ˎ Do not use the wireless networking feature in the following
locations:
– Areas where wireless network use is prohibited, such as in
hospitals. Abide by medical institution regulations when
using the system on their premises.
– Areas near fire alarms, automatic doors and other types of
automated equipment.
3D images
Some people may experience discomfort (such as eye strain, eye
fatigue, or nausea) while watching 3D video images or playing
stereoscopic 3D games on 3D televisions. If you experience such
discomfort, you should immediately discontinue use of your
television until the discomfort subsides.
Generally we recommend that you avoid prolonged use of your
PlayStation ® 4 system and take 15 minutes breaks during each
hour of play. However, when playing stereoscopic 3D games or
watching 3D video images, the length and frequency of
necessary breaks may vary from person to person – please take
breaks that are long enough to allow any feelings of discomfort
to subside. If symptoms persist, consult your doctor.
The vision of young children (especially those under 6 years old)
is still under development. Consult with your child's doctor or
optometrist before allowing young children to watch 3D video
images or play stereoscopic 3D games. Adults should supervise
young children to ensure they follow the recommendations
listed above.
