CAUTION: This product contains invisible laser
radiation. Avoid staring into the beam or viewing directly with
optical instruments. Use only as specified in the Owner’s Manual to
prevent hazardous radiation exposure. Laser mechanism servicing
should be done at the authorized service facility.

Performance Specifications

1. The heavy notes on the schematic denote the primary signal
path.

2. Voltage measurements are based on AC input at 120 volts,
50/60Hz, with all voltages +/-10% relative to ground using a high
impedance voltmeter.

3. Standard units for components: a. Resistors – ohms; b.
Capacitors – microfarads (uF); c. Inductors – microhenries
(uH).

4. Notations on PC board drawings: Square pad indicates: a.
Polarized Capacitors – Positive; b. Diodes – Cathode; c. Others –
Pin 1.

5. Critical parts are marked with a warning symbol. Use only
manufacturer-recommended replacement parts.

NOTES

MCD201

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 HR056 with the MCD201.

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).
