Error code

Possible symptom

Description of problem

U02

Power supply cut

During operation, when PDET switches to OFF (PDET - 1.534V) due to fall of power supply voltage
fall, the power supply will be automatically switched OFF.

If REM_STBY = L, VCCDET = H the system shall be judged to have low battery and [......UO2] shall
be displayed for 10 seconds.

To check REM_STBY and VCCDET, chattering check will be read-in twice 1 sec after PCONT is set
to L.

Power supply state shall be checked using REM_STBY and VCCDET inputs. If power ON is
executed from power OFF (REM_STBY = L and VCCDET = H), error number [......UO2] will be
displayed for 5 seconds. This error number will not be memorized.

F15

CD REST_SW
abnormal

At initial setting of CD traverse position, if REST_SW ON is not detected even though the fail safe
timer time is over (10 sec), this is memorized as an error and the error number can be cleared only
at the start up of micro-p after reset.

H15

CD OPEN_SW
abnormal

During normal operation, if CD OPEN_SW ON is not detected within 4 sec, then H15 will be
memorized in memory. The error code can be cleared only at the start up of micro-p after reset.

H01

DECK operation
abnormal (reel motor,
solenoid, and
MODE_SW)
(provisional)

During normal operation, if mechanism error process is executed once by mode switch against the
same deck operation, it is judged as mechanism abnormality and this is memorized as an error.

Conditions for judging mechanism error:

−

Mode switch ON is not detected 800 ms after plunger activation for PLAY / REC process.

−

Mode switch ON is not detected 800 ms after plunger activation for FF / REW process / Mode
switch OFF is not detected 800 ms after plunger activation after detecting Mode SW ON / Mode
Switch ON is not detected 800 ms after detecting Mode switch OFF.

−

If Mode switch comes ON at STOP / PAUSE state (normal condition), this is judged as an Error:

Main purpose for this Self Diagnosis is to diagnose a partial short of the deck.

Mechanical error process caused by EJECT operation will not be counted.

This error number can be cleared only at the start up of micro-p after reset.

F26

Communication
between CD servo LSI
and microp abnormal

At the time of switching to CD function, SENSE = H will be detected using DTMS system setting
command. If the error is memorized when SENSE = L is not detected within fail safe timer time (20
sec), [F26] will be displayed simultaneously. This display will be retained if the power is ON and at
CD function. If this error occurs, CD operation afterward cannot be executed as in the case of
[NO.DISC.]. This error number can be cleared only at the start up of micro-p after reset.

14.1.5. Self-diagnosis mode Deck Mechanism

Activate the Self Diagnosis mode for the Deck and the following Self Diagnosis will be conducted.

Error Code

Description

H01:

If MODE_SW abnormal is detected during normal operation, it will be memorized. The detection and memory
shall be done for Deck.

H02:

RECINH_SW abnormal.

H03:

HALF_SW abnormal.

F01:

Reel pulse abnormal.

Operating Procedures

1. Activate the Self Diagnosis mode with the Deck unloaded.
2. The test mode will be displayed ([T] at the 1st digit shows TEST) and detection shall be executed to check RECINH_SW,

HALF_SW are in the OFF state (the tape counter display is retained).

3. Load a cassette tape (with recording preventive tab present) into the deck and close the cassette holder.
4. At this instant with the cassette loaded in, RECINH_SW, HALF_SW will be checked and confirmed at this stage by the software.

Press FF key to proceed the self-diagnosis. The FF operation will stop automatically after 3 sec. If abnormal operation is
detected, the tape will stop automatically after 1 sec. During the FF operation, the Reel Pulse will be checked by the software.

5. After the tape stops, the Error codes will be displayed by toggling the STOP

key. (For a more detailed explanation, refer to

Figure 14-2).
