12.5. (VHS) Description of Self Diagnosis Memory

In this Self-Diagnosis Function, in case error has occurred continuously, maximum of the newest 3 error data are
memorized.
And in order to analyze cause of error, the error number and the supplementary data of mode, mechanism position and
so on are memorized.
12.5.1. (VHS) Error Number and Supplementary Data
The Supplementary Data as shown below are memorized to each error number.
Error No.
01 The cylinder could not be started.
(Error of the cylinder or the cylinder driver.)
02 The CAP FG could not be detected.
03 Mechanism lock during without the unloading and the
cassette-up.
04 Mechanism lock during unloading
05 S-reel pulse cannot be detected when a cassette
tape is inserted.
(Error of the S-reel system or the Capstan system.)
06 Mechanism lock during the Cassette-up.
07 The recording circuit can not be operated in REC
mode.
08 The recording circuit is operated in except for REC
mode.
11 Cylinder clogs during the PLAY mode.
15 S-reel pulse cannot be detected when a cassette
tape is inserted.
(Error of the S-reel system or the Capstan system.)
16 Detection of the Cylinder lock during the constant
rotation
17 Detection of S-reel lock during the constant tape
running
18 Detection of T-reel lock during the constant tape
running
20 NG1 in the PG Shifter Automatic Adjustment
(The cylinder rotation is unstable during the
automatic adjustment.)
21 NG2 in the PG Shifter Automatic Adjustment
(The vertical sync signal is lacked while over 5
seconds on the alignment tape.)
22 NG3 in the PG Shifter Automatic Adjustment
(The installing position of Heads to the cylinder is our
of specification.)
23 NG4 in the PG Shifter Automatic Adjustment
(The servo is not locked to the cylinder for more than
10 sec.)
80 An exceptional ejection depends on a Error
