NOTES

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

. Unless otherwise noted. all voltages indicated on the

schematics are measured under the following conditions:

3. AC input at 120 volts. 50/60Hz.
b. All voltages are +/-10% with respect to ground. A
high impedance (10 megaohrn) voltmeter must be used.

, 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 ]

WARNING

Parts marked with the symbol have critical
characteristics, Use only replacement parts recom-
mended by the manufacturer.

Use McIntosh Remote Control Model HRLO42 with the
CR 1 6.
