Appendix 149
When Using Your Device Near Other Electronic Devices
Your wireless handheld portable device is a low power radio transmitter and receiver. When it is ON, it receives
and also sends out radio frequency (RF) signals.
Most modern electronic equipment is shielded from RF energy. However, certain electronic equipment
may not be shielded against the RF signals from your wireless device; therefore, use of your device must be
restricted in certain situations.
In addition, the computer portion of your device produces low levels of RF energy due to the generation of
digital timing pulses by its clock oscillator circuits. Your device has been equipped with internal shielding
to minimize stray emissions of RF energy. However, use of the computer functions of your device must be
restricted in certain situations.
PACEMAKERS
The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches be
maintained between a handheld 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.
Never come closer than six (6) inches to a person with a heart pacemaker implant when using your device.
Doing so could result in interference with the function of the pacemaker.
Persons with pacemakers:
Should ALWAYS keep the phone more than six inches from their pacemaker when the phone is
turned ON.
Should not carry the phone in a breast pocket.
Should use the ear opposite the pacemaker to minimize the potential for interference.
Note This is not necessary if the device is not held to the ear.
If you have any reason to suspect that interference is taking place, turn the phone OFF 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, or call the customer service line to discuss alternatives.
For more regulatory information about hearing devices, see “FCC Hearing-Aid Compatibility (HAC)
Regulations for Wireless Devices”.
OTHER MEDICAL DEVICES
If you use any other personal medical device, consult the manufacturer of your device to determine if it
is adequately shielded from external RF energy. Your physician may be able to assist you in obtaining this
information.
HOSPITALS AND HEALTH CARE FACILITIES
Turn your device OFF 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.
ELECTRONIC DEVICES IN VEHICLES
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles.
Check with the manufacturer or its representative regarding your vehicle. You should also consult the
manufacturer of any equipment that has been added to your vehicle.
POSTED FACILITIES
Turn your device OFF where posted notices so require.
