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 car kit
phone.
Pacemakers
Pacemaker manufacturers recommend that a minimum
separation distance of 20 cm be maintained between the
vehicle antenna 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.
If you have any reason to suspect that interference is taking
place, switch your car kit phone over to off mode immediately.
