1. The heavy notes on the schematic denote the primary

signal path.

2. Unless otherwise noted, all voltages indicated on the

schematics are measured under the following conditions:

a. AC input at 120 volts, 50/60Hz.

b. All voltages are +/-10% with respect to ground. A

high impedance (10 megaohm) voltmeter must be used.

3. Unless otherwise specified:

a. Resistor values are in ohms.

b. Capacitor values are microfarads (uF).

c. Inductor values are in microhenries (uH).

4. On PC board drawings, Square pad indicates:

a. Polarized Capacitors - Positive

b. Diodes - Cathode

c. Others - Pin 1

5. WARNING

Parts marked with the symbol have critical

characteristics. Use only replacement parts recom-

mended by the manufacturer.

SAFETY INFORMATION

NOTES

CAUTION: The use of optical instruments with this

product will increase eye hazard.

This product utilizes a class 1 laser. Invisible laser

radiation is emitted from the optical pickup lens when the

unit is turned on.

1. Do not look directly into the pickup lens.

2. Do not use optical instruments to look at the pickup

lens.

3. Do not adjust the preset variable resistor on the

optical pickup.

4. Do not disassemble the optical pickup unit.

5. Use of controls or adjustment or performance of

procedures other than those specified herein may

result in hazardous radiation exposure.

6. Replace optical pickup only with manufacturers

specified type.
