Additional safety information

Operating environment

Remember to follow any special regulations in force in any
area and always switch off your device when its use is
prohibited or when it may cause interference or danger. Use
the device only in its normal operating positions. This device
meets RF exposure guidelines when used either in the normal
use position against the ear of when positioned at least 7/8
inch (2.2 cm) away from the body. When a carry case, belt
clip, or holder is used for body-worn operation, it should not
contain metal and should position the device at least 7/8 inch
(2.2 cm) away from your body.
In order to transmit data files or messages, this device
requires a quality connection to the network. In some cases,
transmission of data files or messages may be delayed until
such a connection is available. Ensure the above separation
distance instructions are followed until the transmission is
completed.
Medical devices
Operation of any radio transmitting equipment, including
wireless phones, may interfere with the functionality of
inadequately protected medical devices. Consult a physician
or the manufacturer of the medical device to determine if
they are adequately shielded from external RF energy or if you
have any questions. Switch off your device in health care
facilities when any regulations posted in these areas instruct

you to do so. Hospitals or health care facilities may be using
equipment that could be sensitive to external RF energy.
PACEMAKERS Pacemaker manufacturers recommend that a
minimum separation of 6 in (15.3 cm) be maintained between
a wireless phone and a pacemaker to avoid potential
interference with the pacemaker. These recommendations are
consistent with the independent research by and
recommendations of Wireless Technology Research. To
minimize the potential for interference, persons with
pacemakers should
• Always keep the device more than 6 inches (15.3 cm) from
their pacemaker when the device is switched on
• Not carry the device in a breast pocket
• Hold the device to the ear opposite the pacemaker to
minimize the potential for interference.
If you have any reason to suspect that interference is taking
place, switch off your device immediately.
HEARING AIDs Some digital wireless devices may interfere
with some hearing aids. If interference occurs, consult your
service provider.
Vehicles
RF signals may affect improperly installed or inadequately
shielded electronic systems in motor vehicles such as
electronic fuel injection systems, electronic antiskid (antilock)
braking systems, electronic speed control systems, air bag
