ADAT XT Reference Manual 83
2. Turn off the POWER switch. Hold REWIND and FAST FORWARD while turning
the power back on again. The display will read "CALIbrAt".
3. Insert the tape into the transport.
4. At this time the unit will adjust the brake tension automatically. The transport will
shuttle back and forth for about 5 minutes. During the operation, the tape will
half-eject twice. This is normal.
5. The display should briefly read "PaSS" before ejecting the tape fully and
returning to the "ADAT-XT" start-up screen. The brakes have now been
recalibrated.
If the "CAL brAc" message appears again shortly after a brake calibration has been
performed, there may be something wrong with the tape being used. Check
operation with another tape. If the message persists, the unit must be professionally
serviced.
Note: If these errors occur only with a certain tape, or display once in a while, it’s
probably not cause for concern. Errors 1 through 3 and 9 can indicate conditions that
may damage a tape; the other errors won’t damage the tape or the machine. Backup
the data from that tape to another machine, if possible, and continue working from the
backup copy.
STEPS TO TAKE BEFORE CALLING FOR HELP
If an error message is displayed or if an ADAT starts behaving strangely, then please
follow the suggested steps below:
1 Stop the tape playing (or recording). Does the error go away?
2 Rewind the tape a minute or two. Press [PLAY]. Does the error recur?
3 Eject the tape. Place it back in the XT and press [PLAY]. Does the error recur?
4 Turn down the volume of any mixer or amplifier you have connected to the
outputs of the XT. Turn the power of the XT off, wait a minute and then re-power
the XT. Repeat steps 1 to 3. Does the error come back?
5 If it does, then try a different tape. Repeat steps 1 to 3. Does the problem recur?
6 Try the tape in a different XT or ADAT. (If you are using a single ADAT system,
see if you can visit your dealer.) It does not make sense to send your XT in for
service when there may be only a problem with, for example, some tapes that
you are using. If the same problems occur in another XT or ADAT, then either the
tape is faulty or it was formatted on an out of alignment XT or ADAT. At this point,
you should call Alesis Product Support. If the problem does not occur, and the
tape works fine, then we need to look at your XT. You need to call Alesis Product
Support.
Whatever happens, the answers to all these questions are useful information for our
Product Support representatives. The more we know, the faster we can discover the
cause of your problems. You will help us isolate whether the problem lies in the XT,
the tape or somewhere else.
