NOTES
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

WARNING Parts marked with the symbol have critical characteristics. Use only replacement parts recommended by the manufacturer.
SAFETY INFORMATION
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. Laser output: Wavelength: 0.65mW 665nm This product utilizes an embedded class 2 laser (IEC825).
