2 1. 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. 2. Unless otherwise specifi ed: a. Resistor values are in ohms. b. Capacitor values are microfarads (uF). c. Inductor values are in microhenries (uH) 3. On PC board drawings, Square pad indicates: a. Polarized Capacitors - Positive b. Diodes - Cathode c. Others - Pin 1 4. WARNING Parts marked with the symbol have critical characteristics. Use only replacement parts recom- mended by the manufacturer. 5. Use McIntosh Remote Control Model HR063 with the MS750. NOTES SAFETY INFORMATION PERFORMANCE SPECIFICATIONS CAUTION: Invisible Laser Radiation when open.
