*:
In case of adjustment as a single unit, enter the signal at 13P(RECL) and 15P(RECR) of CN2601(MAIN UNIT). At this time, connect an output buffer amplifier to the oscillator, and then connect a series resistor (180 �) after the impedance has become sufficiently low. (For MPX filter impedance matching)
