10  For your safety
Interference with electronic devices
Some electronic devices may be prone to malfunction 
due to the lack of protection from RF energy that is 
present when your radio is
 transmitting.
Examples of electronic devices that may be affected by 
RF energy
 are:
■ aircraft electronic systems
■ vehicular electronic systems such as fuel injection, 
anti-skid brakes, and cruise control
■ medical devices such as hearing aids 
and pacemakers
■ medical equipment in hospitals or health 
care facilities.
Switch off the radio before boarding an aircraft. Using 
your radio while in the air is not
 permitted.
Consult the manufacturer (or its representative) of any 
such electronic devices to determine whether electronic 
circuits in those devices will perform normally when the 
radio is
 transmitting.
If you have a pacemaker, immediately turn off the radio 
if you suspect it is interfering with the pacemaker.
If there is interference between your hearing aid and the 
radio, please discuss an alternative solution with the 
hearing aid manufacturer.
Potentially explosive atmospheres and 
blasting areas
Warning: Turn off the radio before approaching blast-
ing caps, a blasting area, or any area where you are 
instructed to turn off a two-way radio. Obey all signs 
and instructions. Interference with blasting operations 
could cause serious injury or death.
