connected to the station's grounding system for safe operation. The amplifier is designed to meet
international safety standards and complies with CE safety and electromagnetic compatibility requirements,
as well as FCC regulations. This operating manual contains an assortment of precautions and warnings
that MUST BE FOLLOWED BY THE USER to ensure safe operation of the amplifier.

The amplifier works with voltages up to 3000 V dc, which are potentially LETHAL! You must unplug the
amplifier from the line (mains) wall outlet and WAIT AT LEAST 30 minutes before removing the cover of the
amplifier. Do not touch any part inside while the amplifier is open because dangerous voltages may remain
present.
