Radio waves
Radio waves may affect electronic equipment or medical
devices (for example, pacemakers), which may cause
malfunctions and possible injuries.
• 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).
• 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, 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.
