105. Squelch CircuitThe detected output which is outputted from the pin 11 of IC108 is inputted topin 13 of IC108 after it was been amplified by IC10

119) PLL Synthesizer Circuit (DR-435)1. PLLThe dividing ratio is obtained by sending data from the CPU (IC1) to pin 2 andsending clock pulses to pin

122. Dimmer CircuitThe dimmer circuit makes the output of pin 13 of CPU (IC1) into "H" level at setmode, so that Q9 and Q3 will turn ON to

1311) Power Supply CircuitWhen power supply is ON, there is a "L" signal being inputted to pin 39 (PSW) of CPU which enablesthe CPU to work
