(22) WARNING
Do not operate radio in hazard environments. Explosion or fire may result. Do not
operate radio near unshielded electrical blasting caps. Under certain conditions,
radio can interfere with blasting operations and may cause an explosion. Turn your
radio OFF to prevent accidental transmission when in a “blasting area” or in areas
posted “Turn your radio off”. Construction crews often use remote control RF
devices to set off explosives.
