Key in "B4". Then the write error count (write retry count) is
indicated in hexadecimal notation to the display of SOB.
(g) Check if the write error count is less than SO in hexadecimal
notation (12S in decimal notation).
Remark
The write error count changes greatly depending upon the
status of the work tape used. Therefore, the above-
mentioned value is a reference value.
(h) Key in "A4". The tape is rewound up to BOT and the indicator RDY
on SOB lights up.
(i) Key in "BO". The MTU starts a read error test.
(j) After the completion of the read error test, the transfer block
count is indicated in hexadecimal notation to the display of SOB.
Therefore, check if it agrees with the transfer block count
obtained in the write error test.
(k) Key in "B2", and "B3". Then, EXCEPTION STATUS is indicated to the
display of SOB. Check if the display is "SEAO".
Key in "B4". Then, the read error count (read retry count) is
indicated in hexadecimal notation to the display of SOB.
(1) Check if the read error count is less than 1.
Remark The read error count changes greatly depending upon the
status of the work tape used. Therefore, the
above-mentioned value is only a reference value.
