*These specifications are intended primarily for the use of the serviceman. Refer to the appropriate Specification Sheet for
the complete specifications.
Although the highest DC voltage supplied to the transmitter is + 24VDC, high currents may be drawn under short circuit
conditions. These currents can heat metal objects such as tools, rings, watchbands, etc., enough to cause burns. Be careful
when working near energized 24 Volt 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!
