Note 2. For improved pilot sensitivity and overload characteristics, replace the .039µF capacitor between Pin7
and Pin8 with a Series L–C Network (L = 4.7mH, C = 0.015µF). Under these conditions, Indicator
Lamp Sensitivity: “ON” = 3.3mV, “OFF” = 2.0mV.
Note 3. For stereo operation, test conditions require a composite stereo input signal (modulated at 1kHz) in-
cluding a 19kHz (18mV) pilot–tone signal.
