System changeover
a. SIF system SW
The SIF system can be changed over by setting A (pin 7) and B (pin 9) to GND and OPEN respectively.

b. IF system SW
The IF frequency becomes 38.9MHz when pin 10 is open.
The IF frequency becomes 38.0MHz when pin 10 is set to GND.
The IF frequency becomes 39.5MHz when pin 10 is set to VCC.
c. Split/inter carrier SW
Inter-carrier is selected by setting the 1st SIF input (pin 13) to GND.
d. Reference frequency changeover SW
The reference frequency becomes 4.43MHz when pin 11 is OPEN.
The reference frequency becomes 4.0MHz when 270k
Ω is connected between pin 11 and GND.
e. AFT mute level, trap point shift SW
By changing the pin 15 voltage, the potential and TRAP point at which AFT is muted can be set to either just or shift
(about +220kHz).

f. FM detector function not used
To stop FM detection VCO without using the SIF circuit, short-circuit pin 1 – GND with resistance of 1k
Ω or less.
