1. Safety Precaution (This “Safety Precaution” is applied only in U.S.A.) 1. Before servicing, unplug the power cord to prevent an electric shock. 2. When replacing parts, use only manufacturer’s recommended components for safety. 3. Check the condition of the power cord. Replace if wear or damage is evident.

screwheads, antenna, control shafts, handle brackets, etc. / Equipment with antenna terminals should read between 2.7M and 3.9M to all exposed parts*. (Fig.1) / Equipment without antenna terminals should read approximately infinity to all exposed parts. (Fig.2) / *Note : Some exposed parts may be isolated from the chassis by design.

3. Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: - No sound is heard when the power is turned on. - Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.

caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). - Handling of traverse deck (optical pickup) 1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock.
Page 8
2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet. Caution : The static electricity of your clothes will not be grounded through the wrist strap.
