Test mode for
checking/Possible failures
Test mode
Function test cam mode 613
Possible causes
.
Faulty operations of the reel
brake
.
Faulty operations of the
function cam (LD) motor or
drive circuit (SV-213 board/
IC201)
.
Incorrect gear position of
the threading mechanism or
function cam
.
Cam mode sensor (SE-295
board/PH1 to PH4) or
detection circuit (SV-213
board/Q803, Q804)
problems
.
Disconnection, faulty
connection of the flexible
board (SE-295 board)
.
Disconnection of the harness
Possible causes
. Faulty operations of the reel
position (shift) motor
. Faulty operations of the reel
table movement mechanism
. Faulty detection of the reel
position sensor (SE-297
board/PH3, PH4) or faulty
detection circuit (SV-213
board/Q805)
. Disconnection or faulty
connection of the flexible
board (SE-297, MT-114)
Possible causes
. Faulty tape top sensor (CC-
68 board/Q1)/tape end
sensor (SE-295 board/Q1)
or detection circuit (SV-213
board/IC3)
. Disconnection or faulty
connection of the flexible
board (SE-295, MT-114,
CC-68)
Possible causes
. Faulty L reel position
sensor (SE-297 board/
PH3)/S reel position sensor
(SE-297 board/PH4)
. Disconnection or faulty
connection of the flexible
board
. Faulty detection circuit (SV-
213 board/Q805)
Operations when
errors occur
SHUT OFF operations are
performed, and only the
EJECT mode is accepted.
The error is displayed until
the cassette is inserted at
the next time.
When errors occur, the
STOP mode is set. Only
the PLAY, FF, and EJECT
modes are accepted.
The error is displayed until
it is corrected.
When errors occur, the
STOP mode is set. Only
the REW and EJECT
modes are accepted.
The error is displayed until
it is corrected.
The error is displayed until
it is corrected.
Error detection method
The mechanism control
MICRO COM. could not
obtain an appropriate input
signal from the cam
position sensor or detected
abnormal current of the
function cam (LD) motor.
The mechanism control
MICRO COM. could not
obtain an appropriate input
signal from the reel position
sensor or detected
abnormal current of the reel
position motor.
The detection signal
(detected tape top or tape
end after SHORT FF or
SHORT REW) was input to
the mechanism control
MICRO COM. from the tape
top sensor or tape end
sensor.
Both the detections signals
from the L reel position
sensor and S reel position
sensor were input to the
mechanism control MICRO
COM.
