DAIR Problems DAIR problems may show up on the maintenance radar scope as a display of the wrong number of targets, no targets or incorrectly positioned targets. The problem could be as simple as opertor error - the wrong SW204 setting or running the wrong transport. If the problem is on one transport only, the problem is probably not with the DAIR itself, but with the tape, heads, etc on the affected deck. If the problem is on both transports, it probably is with the DAIR, and the quickest way to check it out is by using the DAIR test points.
