SAFETY NOTICE
WARNING: Only competent service personnel may carry out work involving the testing or
         repair of this equipment.

This receiver must operate under AC 100-240 volts, 50/60Hz.
Never connect to a DC supply of any other voltage or frequency.

Potential high voltages are present when this receiver is operating.
Operation of the receiver outside the cabinet or with the back cover removed involves a
shock hazard from the receiver.
Servicing should not be attempted by anyone who is not thoroughly familiar with the
precautions necessary when working on high voltage equipment.

Keep wires away from high voltage or high temperature component.

When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the
resistor body 10mm away from the circuit board.

Many electrical and mechanical parts in this equipment have special safety-related
characteristics.
Replacement parts which have such features are identified by designated symbol on the
parts list.
Before replacing any of these components, read the parts list carefully.
If the fuse is blown, replace it with the fuse specified in the Parts List.




                                                                                                2
