These recommendations are consistent with the independent research by, and
recommendations of, Wireless Technology Research. Persons with pacemakers should:
 ALWAYS keep the smartphone more than 6 inches (15 cm) from their pacemaker when
the smartphone is turned on

Not carry the smartphone in a breast pocket
 Use the ear opposite the pacemaker to minimize the potential for interference
 Turn the smartphone off immediately if you have any reason to suspect that interference
is taking place
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.
Use While Driving
Campus installations and warehouse facilities that use vehicles such as forklifts or golf carts
should abide by these guidelines when using Smartphones:

Give full attention to driving and to the road, aisle, or path
 Use hands-free operation, if available
 Pull off the road, aisle, or path and park before making or answering a call
For Vehicles Equipped with an Airbag
Do not place a portable device in the area over the airbag or in the airbag deployment area. An
airbag inflates with great force. If you place the smartphone in the airbag deployment area, and
the airbag inflates, the airbag may propel the smartphone at high speed and cause serious
injury to occupants of the vehicle.
