NOTES
1. The heavy notes on the schematic denote the primary 4. On PC board drawings, Square pad indicates:
signal path. a. Polarized Capacitors - Positive
b. Diodes - Cathode
2. Unless otherwise noted, all voltages indicated on the c. Others - Pin 1
schematics are measured under the following conditions:
a. AC input at 120 volts, 50/60Hz. 5. WARNING
b. All voltages are +/-10% with respect to ground. A Parts marked with the symbol have critical
high impedance (10 megaohm) voltmeter must be used. characteristics. Use only replacement parts recom-
mended by the manufacturer.
3. Unless otherwise specified:
a. Resistor values are in ohms. 6. Use McIntosh Remote Control Model HR056 with the
b. Capacitor values are microfarads (uF). MCD201.
c. Inductor values are in microhenries (uH).
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.
Servicing of laser mechanism is to be
performed at the service facility at
McIntosh Laboratory Inc.
This product incorporates an embedded
Class 3R Laser (IEC60825-1).
