NOTES

MVP861

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 HR052 with the

MVP861.

SAFETY INFORMATION

CAUTION: Invisible Laser Radiation when open.

DO NOT stare into the beam or view
directly with optical instruments. Use of
controls or adjustments or performance
of procedures other than those speci
fied in the Owners Manual may result in
Hazardous Radiation Exposure.

This product incorporates an embedded
Class 3R Laser (IEC60825-1).
