These acoustic signals, differentiating distances and detection widths, may be indicated by changing the frequency of the intermittent sound. A faster intermittent sound or continuous sound shall be used as the distance becomes closer.
         17.2.3. Duration of signalling
         Signalling for an object shall last as long as the object is detected and shall end when the object is no longer detected or when the system is deactivated.
         To reduce the driver's discomfort, the audible signal can be automatically suspended temporarily after a certain time set by the manufacturer has elapsed, provided that the system remains activated. If, while the audible signal is automatically suspended temporarily, the distance to the object becomes shorter, the audible signal shall be automatically resumed. If the distance to the object becomes longer, the audible signal may remain suspended.
         17.2.4. Optical information
         In the case optical information is placed on a monitor used for other information such as meter cluster display or other displays, overlay is allowed and shall comply with the overlay requirements of the RVCS in 16.1.1.2. of this Regulation.
         17.2.5. Operating readiness (System availability)
         Non-operation of the system shall be recognizable to the driver (e.g. Detection system failure by, i.e. warning indication, display information, black screen, absence of status indicator). The information for the driver shall be explained in the operator's manual.
         17.3. Performance of object detection
         17.3.1. Response time
         At least one of the audible or haptic information signals that meets the requirements as described in 17.2., shall be given to the driver within a maximum of 0.6 seconds after the start of the backing event, when tested according to paragraph 2. of Annex 10.
         17.4 The effectiveness of the detection system shall not be adversely affected by magnetic or electrical fields. This shall be demonstrated by compliance with the technical requirements and transitional provisions of UN Regulation No. 10, 05 series of amendments or any later series of amendments.
         18. Modifications of the vehicle type and extension of approval
         18.1. Every modification of the vehicle type shall be notified to the Type Approval Authority which approved the vehicle type. Type Approval Authority shall then either:
              (a)                    Decide, in consultation with the manufacturer, that a new type approval is to be granted; or
              (b)                   Apply the procedure contained in paragraph 18.1.1. (Revision) and, if applicable, the procedure contained in paragraph 18.1.2. (Extension).
         18.1.1. Revision
         When particulars recorded in the information folder have changed and the Type Approval Authority considers that the modifications made are unlikely to have an appreciable adverse effect, and that in any case the vehicle still complies with the requirements, the modification shall be designated a "revision".
         In such a case, the Type Approval Authority shall issue the revised
