• Adjustment location :
L951 (1/3) ....................................................1000kHz
Method : Set to MW 999kHz and adjust L951 (1/3) so that the
test point becomes maximum.
8. MW IF Adjustment
Settings : • Test point : TP8 (Lch), TP9 (Rch)
• Adjustment location :
L802 .................................................... 450kHz
9. DC Balance / Mono Distortion Adjustment
Settings : • Test point : TP3, TP4 (DC)
TP8 (Lch), TP9 (Rch)
(Distortion)
• Adjustment location : L801
• Input level : 60dBµV
Method : Set to FM 98.0MHz and adjust L801 so that the
voltage between TP3 and TP4 becomes 0V ±300mV
with distortion less than 1.2%.
10. Output Level Check
<MW>
Settings : • Test point : TP8 (Lch), TP9 (Rch)
• Input level : 74dBµV
Method : Set to MW 999kHz and check that the test point is
40mV ±3dB.
<FM>
Settings : • Test point : TP8 (Lch), TP9 (Rch)
• Input level : 60dBµV
Method : Set to FM 98.0MHz and check that the test point is
140mV ±3dB.
11. FM Separation Check
Settings : • Test point : TP8 (Lch), TP9 (Rch)
• Input level : 60dBµV
Method : Set to FM 98.0MHz and check that the test point is
more than 12dB.
< FRONT SECTION >
12. MICON OSC Adjustment
Settings : • Test point : TP10 (KEY-SCAN)
TP11 (D-GND)
• Adjustment location : L101
Method : Insert AC plug while pressing of "POWER" key and
"TUNER" function key.
Connect a frequency counter across TP10 and TP11.
Then adjust L101 so that the test point becomes
171.46Hz ±0.17Hz.
[ Manual Reset ]
Make up for RESET after adjustment.
* Reset is to press "POWER" key while pressing of
"CLEAR (STOP)" key.

ADJUSTMENT – 2 <DECK>
< DECK SECTION >
1. Tape Speed Adjustment (DECK 1)
Settings : • Test tape : TTA–100
• Test point : TP8 (Lch), TP9 (Rch)
• Adjustment location : SFR701
Method : Play back the test tape and adjust SFR701 so that the
test point becomes 3000Hz ±5Hz (FWD) and FWD
SPEED ±45Hz (REV) with respect to forward speed.
2. Head Azimuth Adjustment (DECK 1, DECK 2)
Settings : • Test tape : TTA–330
• Test point : TP8 (Lch), TP9 (Rch)
• Adjustment location : Head azimuth
adjustment screw
Method : Play back (FWD) the 8kHz signal of the test tape and
adjust screw so that the output becomes maximum.
Next, perform on REV PLAY mode.
3. PB Frequency Response Check (DECK 1, DECK 2)
Settings : • Test tape : TTA–330
• Test point : TP8 (Lch), TP9 (Rch)
Method : Play back the 315Hz and 8kHz signals of the test
tape and check that the output ratio of the 8kHz
signal with respect to that of the 315Hz signal is
0dB ±5dB.
4. PB Sensitivity Check (DECK 1, DECK 2)
Settings : • Test tape : TTA–200
• Test point : TP8 (Lch), TP9 (Rch)
Method : Play back the test tape and check that the output level
of the test point is 140mV ±3dB.
