*Note :
03-4 in the FRONT END OSC ASSEMBLY and 03-1 to
D3-3 in the TUNER ASSEMBLY are used the even
characteristic varactor.
Therefore, when the FRONT END OSC ASSEMBLY is
replaced, replace 03 —1 to 03-3 in the TUNER
ASSEMBLY together.
Use D3-1 to 03-3 so that D3-1 to 03-3 as
even characteristic as 03 —4 are installed in
the FRONT END OSC ASSEMBLY.
