• Use hands-free operation, if available;
• Pull off the road and park, before making or answering a call, if driving
conditions demand so.
Electronic Devices
Most modern electronic equipment is shielded from RF signals.
However, certain electronic equipment may not be shielded against the RF
signals from your wireless phone.
Pacemaker
The Medical Industry Manufacturers Association recommends a minimum
distance of fifteen (15) centimeters, or six (6) inches, between a handheld
wireless phone and a pacemaker, in order to avoid potential interference
between them.
These advices are consistent with independent researches, and with
recommendations based on wireless technology research.
People with pacemakers should:
• ALWAYS keep the phone at least fifteen centimeters (six inches) from
their pacemaker, whenever the phone is turned on;
• Not carry the phone in a shirt pocket;
• Use the ear opposite to the pacemaker, to minimize the potential
interference;
• If you have any reason to suspect that interference is taking place, switch
off your phone immediately.
