.
Be sure to use the specified alignment tape.
If the specified cassette tape is not used, the adjust-
ment cannot be properly performed even if the
message “Auto Adjust Complete” is displayed on
completing the adjustment. Insert alignment tape
SR5-1 (for 525/60 system) or SR5-1P (for 625/50
system).
. Take care that the tape transport mode does not
change during automatic adjustment.
Any adjustment cannot be properly performed in
modes other than tape transport that was set auto-
matically. Moreover, in modes other than tape
transport, the automatic adjustment cannot be
performed any longer or “FAIL” or “NG” is dis-
played as the adjustment result. Therefore, pay
attention to the transport start position of the tape so
that the end and beginning of the tape are not
detected during adjustment. The minimum tape
amount required for normal automatic adjustment is
shown in the table on the next page. However, the
tape amount increases or decreases when abnormali-
ty occurs.
