VAROITUS!
Laitteen kayttaminen muulla kuin tassa kayttoohjeessa mainitulla tavalla saattaa altistaa kayttajan turvallisuusluokan 1 ylittavalle nakymattomalle lasersateiiylle.
VARNING! Om apparaten anvands pa annat

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).
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.
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.
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).
