2.8.3 EMG content description
Note: EMG contents "E08/E09" are for the model with Dynamic Drum (DD).
FDP
E01: Loading EMG
When the mechanism mode cannot be
changed to another mode even when the
loading motor has rotatedfor more than 4 sec-
onds in the loading direction, [E:01] is identi-
fied and the power is turned off.
When the mechanism mode cannot be
E02: Unloading EMG
changed to an-other mode even when the
loading motor has rotatedfor more than 4 sec-
onds in the unloading direction, [E:02] is iden-
tified and the power is turned off.
When the take-up reel pulse has not been
E03: Take Up Reel
generated for more than 4 seconds in the cap-
Pulse EMG
stan rotating mode, [E:03] is identified, the
pinch rollers are turned off and stopped,and
the power is turned off. However, the reel
EMG isnot detected in STILL/SLOW modes.
When the drum FG pulse has not been input
E04: Drum FG
for more than 3 seconds in the drum rotating
EMG
mode, [E:04] is iden-tified, the pinch rollers are
turned off and stopped, and the power is
turned off.
When the eject operation does not complete in
E05: Cassette Eject
3 seconds after the start, [E:05] is identified,
EMG
the pinch rollers are turned off and stopped,
and the power is turned off. When the cas-
sette insertion operation does not complete in
3 seconds after the start, the cassette is eject-
ed. In addition, when the operation does not
complete within 3 seconds after the start,
[E:05] is also identified and the power is
turned off immediately.
When the capstan FG pulse has not been
E06: Capstan FG
generated for more than 1 second in the cap-
EMG
stan rotating mode, [E:06] is identified, the
pinch rollers are turned off and stopped, and
the power is turned off. However, the capstan
EMG is not detected in STILL/SLOW/FF/REW
modes.
When short-circuiting of the SW power supply
E07: SW Power
with GND has lasted for 0.5 second or more,

and the power is turned off.
When DD tilting does not complete in 4 sec-

EMG
When the DD FG pulse is not generated within
2.5 seconds, [E:09] is identified, the tilt motor
E09: DD FG EMG
is stopped and the power is turned off.
E0A: Supply Reel
When the supply reel pulse has not been gen-
Pulse EMG
erated for more than 10 seconds in the cap-
stan rotating mode, [E:0A] is identified and the
cassette is ejected (but the power is not
turned off). However, note that the reel EMG
is not detected in the SLOW/STILL mode.
EC1 or EU1:
Presupposing the presence of the control pulse output in the PLAY mode, when the value obtained by mixing the two V.FM output channels (without
Head clog warning
regard to the A.FM output) has remained below a certain threshold level for more than 10 seconds, [E:C1] or [E:U1] is identified and recorded in the
emergency history. During the period in which a head clog is detected, the FDP and OSD repeat the "3-second warning display" and "7-second noise
picture display" alternately.
EMG code : "E:C1" or "E:U1" / FDP : "U:01" / OSD : "Try cleaning tape." or "Use cleaning cassette."
The head clog warning is reset when the above-mentioned threshold has been exceeded for more than 2 seconds or the mode is changed to another
mode than PLAY.

1. The mechanism is locked in the middle of mode transition.
2. The mechanism is locked at the loading end due to the encoder position reading error during mode
transition.
3. Power is not supplied to the loading MDA.
1. The mechanism is locked in the middle of mode transition.
2. The mechanism is locked at the unloading end due to the encoder position reading error during
mode transition.
3. Power is not supplied to the loading MDA.
1. The take-up reel pulse is not generated in the FWD transport modes (PLAY/FWD SEARCH/FF,
etc.) because;
1) The idler gear is not meshed with the take-up reel gear;
2) The idler gear is meshed with the take-up reel gear, but incapable of wind-ing due to too large
mechanical load (abnormal tension);
3) The take-up reel sensor does not output the FG pulse.
2. The supply reel pulse is not generated in the REV transport modes (REVSEARCH/REW, etc.) be-
cause;
1) The idler gear is not meshed with the supply reel gear.
2) The idler gear is meshed with the supply reel gear, but incapable of wind-ing due to too large a
mechanical load (abnormal tension);
3) The supply reel sensor does not output the FG pulse.
3. Power is not supplied to the reel sensors.
1. The drum could not start or the drum rotation has stopped due to too large a load on the tape, be-
cause;
1) The tape tension is abnormally high;
2) The tape is damaged or a foreign object (grease, etc.) adheres to the tape.
2. The drum FG pulse did not reach the System controller CPU because;
1) The signal circuit is disconnected in the middle;
2) The FG pulse generator (hall device) of the drum is faulty.
3. The drum control voltage (DRUM CTL V) is not supplied to the MDA.
4. Power is not supplied to the drum MDA.
1. The cassette cannot be ejected due to a failure in the drive mechanism of the housing.
2. When the housing load increases during ejection, the loading motor is stopped because of lack of
headroom in its drive torque.
Housing load increasing factors: Temperature environment (low temperature, etc.), mechanism
wear or failure.
3. The sensor/switch for detecting the end of ejection are not functioning normally.
4. The loading motor drive voltage is lower than specified or power is not sup-plied to the motor
(MDA).
5. When the user attempted to eject a cassette, a foreign object (or perhaps the user's hand) was
caught in the opening of the housing.
1. The capstan could not start or the capstan rotation has stopped due to too large a load on the tape,
because;
1) The tape tension is abnormally high (mechanical lock);
2) The tape is damaged or a foreign object (grease, etc.) is adhered to the tape (occurrence of
tape entangling, etc.).
2. The capstan FG pulse did not reach the System controller CPU because;
1) The signal circuit is disconnected in the middle;
2) The FG pulse generator (MR device) of the capstans is faulty.
3. The capstan control voltage (CAPSTAN CTL V) is not supplied to the MDA.
4. Power is not supplied to the capstan MDA.
1. The SW 5 V power supply circuit is shorted with GND.
2. The SW 12 V power supply circuit is shorted with GND.
1. The absolute value sensor is defective. (The soldered parts have separated.)
2. The pull-up resistor at the absolute sensor output is defective. (The soldered parts have separat-
ed.)
3. Contact failure or soldering failure of the pins of the connector (board-to-board) to the absolute val-
ue sensor.
4. The absolute value sensor data is not sent to the System Controller CPU.
1. The FG sensor is defective. (The soldered parts have separated.)
2. The pull-up resistor at the FG sensor output is defective. (The soldered parts have separated.)
3. Contact failure or soldering failure of the pins of the connector (board-to-board) to the FG sensor.
4. The power to the sensor is not supplied. (Connection failure/soldering failure)
5. The FG pulse is not sent to the System Controller CPU.
6. The tilt motor is defective. (The soldered parts have separated.)
7. The drive power to the tilt motor is not supplied. (Connection failure/soldering failure)
8. The tilt motor drive MDA - IC is defective.
9. Auto-recovery of the DD tilting cannot take place due to overrun.
1. The supply reel pulse is not generated in the FWD transport mode (PLAY/FWD SEARCH/FF, etc.)
because;
1) PLAY/FWD or SEARCH/FF is started while the tape in the inserted cassette is cut in the middle;
2) A mechanical factor caused tape slack inside and outside the supply reel side of the cassette
shell. In this case, the supply reel will not rotate until the tape slack is removed by the FWD
transport, so the pulse is not generated until then;
3) The FG pulse output from the supply reel sensor is absent.
2. The take-up reel pulse is not generated in the REV transport mode (REVSEARCH/REW, etc.).
1) REV SEARCH/REW is started when the tape in the inserted cassettehas been cut in the middle;
2) A mechanical factor caused tape slack inside and outside the take-up reel side of the cassette
shell. In this case, the supply reel will not rotate until the tape slack is removed by the REV
transport, so the pulse will not be generated until that time;
3) The FG pulse output from the take-up reel sensor is absent.
3. The power to a reel sensor is not supplied.
