Do not use the terminal in an environment where strong radiation or magnetic fields may exist. Note that
the terminal is for indoor use only.
Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF) signals. However, certain electronic
equipment may not be shielded against the RF signals from your terminal.
Pacemakers Pacemaker manufacturers recommend that a minimum separation of 20 cm (6 inches) 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. Persons with pacemakers:
• Should always keep the terminal more than 20 cm (6 inches) from their pacemaker when the terminal is
switched on.
• If you have any reason to suspect that interference is taking place, stop using your terminal immediately.
Hearing aids Some digital wireless phones may interfere with some hearing aids. In the event of such
interference, you may want to consult your service provider.
Other medical devices Operation of any radio transmitting equipment, including cellular 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. Do not use your terminal 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.
Posted facilities Do not use your terminal in any facility where posted notices so require.
