within which the system is able to maintain functionality.

              2.3.  Documentation

              2.3.1.  The vehicle manufacturer shall provide the following documentation:

                  (a)  A description of the camera monitor system which gives an explanation of the main function of the system, incl. drawings, pictures, block diagrams, etc.

                  (b)  A description of the location of the camera and the monitor in the vehicle (system overview).

                  (c)  Name of manufacturer of camera, monitor and electronic control units.

                  (d)  Type of camera and monitor. Each unit shall be clearly and unambiguously identifiable (e.g. by marking for hardware and marking or software output for software content) to provide corresponding hardware and documentation association.

                  (e)  Explanation of the warning strategy and the safety concept, as defined by the manufacturer, covering at least the list of failures of paragraph 2.4.

              2.3.2.  For periodic technical inspections, the documentation shall describe how the current operational status of "The System" can be verified.

              2.3.3.  The limits for the boundary of functional operation (e.g. environmental parameters) shall be stated where appropriate to the system performance.

              2.3.4.  Safety concept of the manufacturer

              The manufacturer shall provide a statement which affirms that the strategy chosen allows a safe operation of "The System".

              In the case of a failure, the driver shall be informed for example by a clear and visible warning signal or message display. When the system is activated, the warning shall be present as long as the fault condition persists.

              The fault conditions shall be established and maintained by the manufacturer and shall be made open for inspection by the Technical Service at the time of the type approval.

              2.3.5.  The chosen analytical approach(es) shall be established and maintained by the manufacturer and shall be made open for inspection by the Technical Service at the time of the type approval.

              2.4.  List of failures

              2.4.1.  Camera

               (a) Failure of the camera;

              (b) Electronic noise, reduced detail resolution;

              (c) Defocus of the optics, reduced detail resolution.

              2.4.2.  Monitor

              (a) Failure of monitor display, no image content is displayed;

              (b) Freeze of displayed monitor content, image content is not refreshed;

              (c) Enlarged image formation time, changing image content is blurred.

              2.4.3.  Control unit

               (a) Failure of the control unit;

               (b) Failure in the communication between camera and control unit;

               (c) Failure in the communication between control unit and monitor.

              2.5.  Verification

              2.5.1.  Verification of the performance of the camera monitor system under no-fault and fault conditions shall be conducted against the manufacturer's specification.

              2.5.2.  The verification of the safety concept of the reaction of the camera monitor system shall, at the discretion of the Type Approval Authority, be verified according to the influence of failures in paragraph 2.4. The verification results shall correspond with
