RADIO Function
Is the key
operations ok?
Check the operations of
- to
-pin and the voltage for key
operation. (Table 5)
Is the LCD display correct if
bands are switched each
other?
Can each sound of
bands switched and
output?
IC301 is in normal
operation. Check other
circuits for RADIO parts.
Cause of malfunction
Are the voltages for
PG302 -
and -pin
followed on the table 6
when CN302
is disconnected?
Check the
circuits G
and H of
S201.
Check IC301.
Is the voltage for Q219 collector followed
on the next table when its frequency is up
and down (High end/Low end frequency)?
Can the indication
of "LOCKED" light?
Check the audio
circuits of IC205,
IC206, IC207 and
IC210.
Check IC202 and
Q201 to Q203.
Input port operations of IC301
- and
-pin
Voltages for IC301
-,
- and
-pin at
key operations
Is the voltage for
IC203 -pin
15 V?
Check IC203 or
L214.
Does the local
oscillator work at
IC301 -pin
of
Q301 connector
in FM mode, and
at IC202
-pin
and IC301
-pin
in AM mode?
FM : IC201
Q301,
CN301,
D204
AM : IC202
D206,
Check above.
Check the line of
IC301 -pin
or
the circuits of
Q218 and Q219.
