Panel clearance required in frontof mounting panel is 3/4 inch (1.9cm).Note: When the DVD/CD tray is opened, the panel clearance required infront of mounting panel is 6-3/4 inches (17.2cm).1. The heavy notes on the schematic denote the primarysignal path.2. Unless otherwise noted, all voltages indicated on theschematics are measured under the following conditions:a. AC input at 120 volts, 50/60Hz.b. All voltages are +/-10% with respect to ground. Ahigh 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 - Positiveb. Diodes - Cathodec. Others - Pin 15.WARNINGParts marked with the symbol have criticalcharacteristics. Use only replacement parts recom-mended by the manufacturer.SAFETY INFORMATIONNOTESCAUTION: The use of optical instruments with thisproduct will increase eye hazard.Invisible laser radiation is emitted from the opticalpickup 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 pickuplens.3. Do not adjust the preset variable resistor on theoptical pickup.4. Do not disassemble the optical pickup unit.5. Use of controls or adjustment or performance ofprocedures other than those specified herein mayresult in hazardous radiation exposure.6. Replace optical pickup only with manufacturersspecified type.LUOKAN 1 LASERLAITEKLASS 1 LASER APPARATVAROITUS!
