. 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. In A12 : REC CUR-
RENT menu, insert the tape that can be recorded by
Betacam SX format. In other menus, insert align-
ment tape SR5-1 (for 525/60 system) or SR5-1P (for
625/50 system).
. In A12 : REC CURRENT menu, execute this menu
under a REC INHIBIT indicator on the lower
control panel is off. If this indicator lights, the
cassette tape is automatically ejected.
This indicator lights when a REC inhibit plug on the
cassette tape is pushed or when a REC INHIBIT
switch on the subcontrol panel is set to ON.
. 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.
