available through a public wireless LAN or hotspot service.
Moisture condensation
If the system or disc is brought directly from a cold location to a
warm one, moisture may condense on the lens inside the
system or on the disc. Should this occur, the system may not
operate properly. In this case, remove the disc and turn off and
unplug the system. Do not put the disc back in until the
moisture evaporates (this may take several hours). If the system
still does not operate properly, contact the appropriate
PlayStation® customer service helpline which can be found
within the guarantee booklet.
