Heat Related Concerns
Your device may become very warm during
normal use. It complies with the user-accessible
surface temperature limits defined by the Inter-
national Standards for Safety. Still, sustained
contact with warm surfaces for long periods of
time may cause discomfort or injury. To reduce
potential heat-related concerns, follow these
guidelines:
•
Keep your device and its AC adapter in a well-
ventilated area when in use or charging. Allow
for adequate air circulation under and around
the device.
•
Use common sense to avoid situations where
your skin is in contact with your device or its
AC adapter when it's operating or connected
to a power source. For example, don't sleep
with your device or its AC adapter, or place it
under a blanket or pillow, and avoid contact
between your body and your device when the
AC adapter is connected to a power source.
Take special care if you have a physical con-
dition that affects your ability to detect heat
against the body.
•
If your device is used for long periods, its sur-
face can become very warm. While the tempe-
rature may not feel hot to the touch, if you
maintain physical contact with the device for
a long time, for example if you rest the device
on your lap, your skin might suffer a low-heat
injury.
