Although the highest DC voltage in Mobile Two-Way Radio equipment is supplied by the vehicle battery, high
currents may be drawn under short circuit conditions. These currents can possibly heat objects such as tools,
rings, watchbands, etc., enough to cause burns. Be careful when working near energized circuits!
High-level RF energy in the transmitter Power Amplifier assembly can cause RF burns upon contact. Keep away
from these circuits when the transmitter is energized!
