substitute replacement parts which do not have the same safety characteristics as specified in the parts list may
create shock, fire ,or other hazards.
3. SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
2. When replacing a high wattage resistor(more than 1W of metal oxide film resistor) in circuit board, keep
the resistor about 5mm away from circuit board.
3. Keep wires away from high voltage, high temperature components and sharp edges.
4. Keep wires in their original position so as to reduce interference.
5. Please refer to the user's manual for operating instructions.
