Self-service terminal

A self-service terminal comprising a plurality of devices is described. The devices comprise: a racking handle for moving that device from an operational position to a maintenance position; a primary visual identifier (such as a bright colour)associated with the racking handle, where the primary visual identifier is common for all of the racking handles and is not used for any part of the device except a racking handle; and a secondary visual identifier associated with any other parts of the device that may be safely touched, where the secondary visual identifier is visually distinct (for example, by using a different colour) from the primary visual identifier.
