These can be:

• The opening of the [Tune] display seems to take forever
• The ``quasioptics'' do not seem to move
• There is a problem with ANTLIA (e.g. the telescope will not track a planet or comet after a pointing, or it will not move at all).

In all these cases try the steps in softreboot first and only if this fails you should try the steps in section hardreboot.

If the antenna, subreflector, quasi or any other part in the system misbehaves in some way that is not described here try the solution in section velalogout. There is also a description of some problems and their solutions in section Q&A of SEST Staff Instructions.
