NOTES
1. Unless otherwise noted, all voltages indicated on the
schematics are measured under the following conditions:
a. AC input at rated voltage marked on rear panel.
b. All voltages are +/-10% with respect to ground. A
high impedance (10 megaohm) voltmeter must be used.
c. Impedance switch set to “8”.
2. Unless otherwise speci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. Remote control HR085.
