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.
