Tape Path Alignment Procedures
The tape transporting system is precisely aligned at the factory and under the normal circumstances will not require adjust-
ment. However, if noise appears in the playback picture, it can be considered that the tape damage has occurred or the
tape path has changed, readjustment of the tape path is necessary.
