2)

Set

the

output

at

98

MHz

accurately

by

using

the

frequency

counter,

and

connect

the

terminals

through

the

[HF

in

normal

FM

reception,

and

tune

it

to

98

MHz

of

generator

output

by

observing

the

4)

Re-insert

in

the

opposite

1),

so

that

the

is

connected

to

5)

Adjust

1)

Set

the

3)

Insert

JOO9

socket,

so

that

the

22

k-ohm

resistor

of

JQ09

is

connected

to

JQ03

side.

4)

Short-circuit

the

22

k-ohm

resistor

for

a

few

second

by

using

the

5)

Adjust

so

that

the
