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 recommended by the manufacturer.
6 . Use McIntosh Remote Control Model HR040 with the
MVP851.
SAFETY INFORMATION
CAUTION: The use of optical instruments with this
product will increase eye hazard.
This product utilizes a Class I 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: CLASS IIa / CLASS I
Wavelength: 658nm / 790nm
This product utilizes an embedded Class IIa laser (IEC825).
