WARNING

To avoid risk of electrical shock that can cause death or severe personal injury, disconnect unit from power before

servicing unless tests require power. Discharge capacitors through a 10,000-ohm resistor before handling. Wires

removed during disassembly must be replaced on correct terminals to ensure proper grounding and polarization.
