Interference with electronic equipment
Most modern electronic equipment is shielded from radio frequency signals. However, certain electronic equipment might not be shielded against the radio frequency signals from your BlackBerry device.
Pacemakers: Consult a physician or the manufacturer of your pacemaker if you have any questions regarding the effect of radio frequency signals on your pacemaker. Verify that you are using your BlackBerry device in accordance with the safety requirements associated with your particular pacemaker, which might include the following requirements:
•Always keep your BlackBerry device more than 7.88 inches (20 cm) from the pacemaker when your BlackBerry device is turned on.
•Do not carry your BlackBerry device in your breast pocket.
•When using the phone on your BlackBerry device, use the ear opposite the pacemaker for making and receiving calls to minimize the potential interference.
