Air Bags
An air bag inflates with incredible force. Do not place
objects, including installed and portable wireless equip-
ment, in the area of the air bag or in deployment area of the
air bag. If in-vehicle wireless equipment is improperly
installed and the air bag inflates, serious injury could result.
Electronic Devices
Most modern electronic equipment is shielded from RF
energy; however, RF energy from cellular telephones may
affect some inadequately shielded electronic equipment. RF
energy may affect improperly installed or inadequately
shielded electronic operating and entertainment systems in
motor vehicles. Check with manufacturers or manufacturers
representatives to determine if systems are adequately
shielded from external RF energy. Consult the manufacturer
of any personal medical devices (for example, pacemakers
and hearing aids) to determine if the devices are adequately
shielded from external RF energy. Turn off the phone in
health care facilities when any regulations posted in the
area forbid use of electronic devices. Hospitals or health
care facilities may be using equipment sensitive to external
RF energy.
Pacemakers
Research sponsored by Wireless Technology Research
(WTR) indicates that some wireless telephones cause inter-
ference with pacemakers. NEC America, Inc., endorses the
following recommendations:
•
Wireless phones should be kept at a safe distance from
a pacemaker. Existing data indicate that the greater
the distance between a pacemaker and a wireless
phone, the less the risk of interference. The data fur-
ther indicates that six inches is the proper separation
distance for minimal risk.
•
Practical steps to achieve the recommended separa-
tion distance include not placing a wireless telephone
in the area over the pacemaker, such as a shirt pocket,
when the phone is powered on. (The unit is consid-
ered on when power is being supplied to the phone by
the battery.) Another practical step is to listen into the
phone using the ear opposite the location of the pace-
maker.
•
Note that no comprehensive data indicates that
bystanders with pacemakers are at risk of interference
from another person operating a cellular phone.
