WARNING : Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated
by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to this bus.)
IMPORTANT : Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.
Components having special characteristics are marked and must be replaced with parts having specifi cation equal to those
originally installed.
IMPORTANT NOTICE FOR THE UNITED KINGDOM
Connecting the Plug and Cord
IMPORTANT. The wires in this mains lead are coloured in accordance with the following code:
BLUE : NEUTRAL
BROWN : LIVE
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured makings identifying the terminals in
