NOTES
MCD301
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. Unlessotherwisespecied:
a. Resistor values are in ohms.
b. Capacitor values are microfarads (uF).
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-
edintheOwnersManualmayresult
in Hazardous Radiation Exposure.
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 recom-
mended by the manufacturer.
6. Use McIntosh Remote Control Model HR056 with the
MCD301.
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).

REPACKING INSTRUCTIONS
MCD301
In the event it is necessary to repack the equipment for
shipment, the equipment must be packed exactly as shown
below. It is very important that the four plastic feet are attached to the bottom of the equipment. This will ensure the
proper equipment location on the bottom pad. Failure to do
this will result in shipping damage.
Use the original shipping carton and interior parts only if
they are all in good serviceable condition. If a shipping
carton or any of the interior part(s) are needed, please
call or write Customer Service Department of McIntosh
Laboratory. Refer to page 4. Please see the Part List for the
correct part numbers.
