8.2.3.2. Example of FIP
8.2.4. (VHS) Self-Diagnosis History Memory Function
8.2.4.1. (VHS) Condition for memorizing of the self-diagnosis history
1. The self-diagnosis result and the supplementary data are the condition memorized just as an Error is detected.
2. There are the histories from number 1 to number 3.
3. The latest Error is memorized on history number 1,and then the old histories are shifted to the history number 2, 3.
4. Put out data from the memory number 3 by the shift is deleted.
5. If the latest Error is same with the history number 1 (2nd-latest), it is not memorized.
(The same Error number is not memorized in succession)

There are next conditions in this
mode for enable the mechanism
operations without a cassette tape.
l The starting / finishing edges are
not detected.
l The reel lock is not detected
l The tape and the positions are not
detected.
, And so on.
Press the EJET key for over 3 sec-
onds in this mode, and then the VCR
is shifted into the special modes,
such as PG Adjustment, Model Code
Setting, and so on.
The orders for the motors are as fol-
lows.

3 Self-diagnosis his-
tory (1st)
Error number of history 1 Supplementary data 1 and 2 of his-
tory 1.
In the Self-Diagnosis Memory, next 3
BYTE is memorized for an Error.
1 BYTE: Its Error number
2 BYTE: Its supplementary data
4 Self-diagnosis his-
tory (2nd)
Error number of history 2 Supplementary data 1 and 2 of his-
tory 2.
In these modes, the supplementary
data 3 and 4 instead of the Error
number and supplementary data 1
and 2 are indicated only while press-
ing STOP key.
5 Self-diagnosis his-
tory (3rd)
Error number of history 3 Supplementary data 1 and 2 of his-
tory 3.
