Use of Your Device while Operating a Vehicle
Please consult the manufacturer of any electronic equipment that has been installed in your
vehicle as RF signals may affect electronic systems in motor vehicles.
Please do not operate your device while driving a vehicle. This may cause a severe distraction,
and, in some areas, it is against the law.
Use of Your Device on an Aircraft
Using your device during flight may violate FAA regulations. Because your device may interfere
with onboard electronic equipment, always follow the instructions of the airline personnel, and
turn your device OFF when instructed to do so.
Blasting Areas
In order to avoid interfering with blasting operations, your device should be turned OFF when in
a blasting area or in an area with posted signs indicating that people in the area must turn off
two-way radios. Please obey all signs and instructions when you are in and around a blasting
area.
