ELECTRONIC DEVICES
RF energy from your portable radio may affect
some electronic equipment. Most modern electronic
equipment in cars, hospitals, homes, etc. are shielded
from RF energy. However, in areas that instruct you to
turn off two-way radio equipment, always observe the
rules. If in doubt, turn it off.
AIRCRAFT
Always turn off your portable radio before boarding
any aircraft.
•
Use it on the ground only with crew permission
•
Do not use it in the air
BLASTING AREAS
To avoid interfering with blasting operations, turn
your radio OFF when in a "blasting area" or in areas
posted "turn off two-way radio". Remote control RF
devices are used by some construction crews to set off
explosives.
