quote:A CAT unit should be taken once a year to a VET (Very Expensive Technician) for a system checkup.
Do not attempt to open a CAT. There are no user serviceable parts inside. If a unit emits strange smells or sounds, it should be serviced immediately by a VET.
quote:CAT units have an internal clock. These normally initialize automatic programs (CLEAN, etc.) These cannot be reset by the user. The internal alarm clock often goes off 30 minutes before the user's alarm clock.
quote:You may examine the rear of the CAT unit to determine if it has a male or female scuzzy port. CATs with a male port may emit a non-toxic aerosol. The VET can remove this component. CATs with female ports are plagued by periodic heating problems. The VET can fix this permanently by removing an internal part. Such systems run unix.
