Not carry the radio in the breast pocket.
Use the ear opposite the pacemaker to minimize the potential for interference.
Turn the radio OFF immediately if there is any reason to suspect that interference is taking place.
Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such interference,
you may want to consult your hearing aid manufacturer to discuss alternatives.
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 RF energy. Your physician may be able to assist you in obtaining this
information.
Use of communication devices while driving
Always check the laws and regulations on the use of radios in the areas where you drive.
Give full attention to driving and to the road.
Use hands-free operation, if available.
Pull off the road and park before making or answering a call, if driving conditions or regulations
so require.
Operational Warnings
For vehicle with air bags
Refer to vehicle manufacturer's manual prior to installation of electronic equipment to avoid
interference with air bag wiring.
Do not place a portable radio in the area over an air bag or in the air bag deployment area.
Air bags inflate with great force. If a portable radio is placed in the air bag deployment area
and the air bag inflates, the radio may be propelled with great force and cause serious injury
to occupants of the vehicle.
Potentially Explosive Atmospheres
(Explosive atmospheres refers to hazard classified locations that may contain hazardous
gas, vapors, or dusts.)
Turn off your radio prior to entering any area with a potentially explosive atmosphere unless
it is a portable radio type especially qualified for use in such areas as Intrinsically Safe (for
example, Factory Mutual, CSA, UL, or CENELEC).
Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive
atmosphere can cause an explosion or fire resulting in bodily injury or even death.
The areas with potentially explosive atmospheres referred to above include fueling areas
such as below decks on boats, fuel or chemical transfer or storage facilities, and areas
where the air contains chemicals or particles such as grain, dust or metal powders. Areas
with potentially explosive atmospheres are often, but not always, posted.
Blasting Caps And Blasting Areas
To avoid possible interference with blasting operations, turn off your radio when you are
near electrical blasting caps, in a blasting area, or in areas posted: "Turn off two-way radio."
Obey all signs and instructions.
