the vehicle is not driving straight, the field of view may change following the vehicle trajectory.
         16.1.2. Operating readiness (System availability)
         Non-operation of the system shall be recognizable to the driver (e.g. RVCS 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.
         16.1.2.1. Response time
         The rear-view image meeting the requirements described in 15.2. shall be provided within a maximum of 2.0 seconds after start of the backing event, when tested according to paragraphs 2. of Annex 9.
         16.1.3. Monitor inside the vehicle
         16.1.3.1. The monitor defined size shall be visible without any obstruction from the ocular reference point. A virtual testing is acceptable.
         16.1.4. Obstruction of the driver's direct view caused by the installation of a device for indirect vision shall be restricted to a minimum.
         16.2. Vehicles may be equipped with additional devices for indirect vision.
         16.3 Notwithstanding the provisions above, any other design concept shall be demonstrated to the satisfaction of the Technical Service within the safety concept that is provided in the provisions above.
         16.4 The effectiveness of the RVCS 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.
         17. Requirements for detection systems
         17.1. System activation
         The system shall be activated when the backing event starts. If proper functioning cannot be effected, either the system shall automatically shut off or the driver shall be able to deactivate the system manually.
         The detection system shall remain active as long as either the vehicle direction selector is in the reverse position or the backing event is not ended.
         In case the vehicle can detect coupling with a coupling device, the system may be switched off.
         17.2. Driver interface and information presentation strategy
         17.2.1. The system shall have at least two kinds of information signal selected from audible, optical, and haptics.
         17.2.1.1. As long as one information signal remains active, the driver may de-activate the other information signals.
         17.2.2. Audible information
         When an object is detected in the rear horizontal area as described in paragraph 1.3. of Annex 10. while the reverse gear is selected/engaged, audible information in accordance with ISO 15006:2011 shall be given.
         In presenting audible information, the distance to the target may be identified by two or more acoustic signals. 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
