ACO-2200 User Guide (v5.0)
Preventive Maintenance
Preventive Maintenance mainly consists of periodic cleaning. Periodic cleaning reduces instrument breakdown and
increases reliability. Clean the instrument whenever needed (using the guidelines outlined above), based on the
operating environment. Dirty conditions may require more frequent cleaning than a conventional clean room
environment.
Servicing
The ACO-2200 should require little or no in-service maintenance to the installed electronics. Provided the measures
outlined in the section “
” on page 38 are adhered to, the product should perform for
several years without any major user intervention.
Maintenance of components within the product is not usually required, except under exceptional circumstances. If a
fault occurs, please follow the instructions listed in the section “
attempting to service the product. The servicing of any of the internal components requires the unit to be extracted
from the bay and the top cover removed. If your problem cannot be resolved, contact Ross Video for further advice.
If you ordered a Service Option, then removing the unit from the bay and returning it to Ross Video for updating
will provide the user with the opportunity to inspect the unit for any problems relating to the operating
conditions/environment.
Service Safety Overview
Only qualified personnel should perform service procedures. Read this section before performing any service
procedures.

cord from the mains power.
•
Use Care When Servicing With Power On
. Dangerous voltages or currents may exist in this product.
Disconnect power, remove battery (if applicable), and disconnect test leads before removing protective panels,
soldering, or replacing components.
•
Observe Static Precautions
. Servicing of this product should be performed only in a static-safe environment,

Workstation mat while servicing the product.
• To avoid electric shock, do not touch exposed connections.
Important Information Regarding the use of Switch Cleaners
Switch Cleaner products usually contain a lubricating additive (along with the alcohol- based propellant), intended
to remain after spraying into relevant components.
Some equipment produced by Ross Video contains components that should not be cleaned using these types of
cleaners, due to the compact nature of the components, their operating characteristics, or their inaccessibility. This
is because push-buttons, for example, rely on clean, dry, conductive contact surfaces to operate correctly. Applying
Switch Cleaner lubricant only serves to attract dust, or worse still could wash-in grease and dust, which could
severely reduce the conductivity of the component parts.
Therefore, Ross Video does not recommend the use of these Switch Cleaner products on their equipment, and will
not be held liable for any fault caused by inadvertent or unqualified use or application of such products.
