              6.2.2.3.4.3. System latency

              A CMS shall have a sufficient short latency to render the scenery nearly at the same time. The latency shall be lower than 200 ms at room temperature 22 °C ± 5 °C.

              6.2.2.3.5. Quality and further ergonomic requirements

              6.2.2.3.5.1. Glare due to high luminance of the monitor

              In order to avoid glare from a high luminance of the monitor, the luminance shall be dimmable in the night condition either manually or automatically.

              6.2.3. Other devices for indirect vision

               It has to be proved that the device meets the following requirements:

              6.2.3.1. The device shall perceive the visual spectrum and shall always render this image without the need for interpretation into the visual spectrum.

              6.2.3.2. The functionality shall be guaranteed under the circumstances of use in which the system shall be put into service. Depending on the technology used in obtaining images and presenting them paragraph 6.2.2.2. above shall be entirely or partly applicable. In other cases this can be achieved by establishing and demonstrating by means of system sensitivity analogous to paragraph 6.2.2.2. above that a function is ensured that is comparable to or better than what is required for and by demonstrating that a functionality is guaranteed that is equivalent or better than that required for mirror- or camera-monitor type devices for indirect vision.

              6.3. Test

              The requirements of paragraph 6.3. shall be considered to be satisfied in the case of monitors of a vehicle fulfilling the provisions of Regulation No. 21.

              6.3.1. Devices for indirect vision in Classes I to VI and Class VII mirrors (having fitments identical to Class III) shall be subjected to the tests described in paragraphs 6.3.2.1. and 6.3.2.2. below. Class VII mirrors with a stem, shall be subjected to the tests described in paragraph 6.3.2.3. below.

              6.3.1.1. The test provided for in paragraph 6.3.2. below shall not be required in the case of any Class II to IV exterior device for indirect vision of which no part is less than 2 m from the ground, regardless of the adjustment position, when the vehicle is under a load corresponding to its maximum technically permissible mass.

              This derogation also applies to the attachments of devices for indirect vision (attachment plates, arms, swivel joints, etc.) which are situated less than 2 m from the ground and which do not project beyond the overall width of the vehicle, measured in the transverse plane passing through the lowest mirror attachments or any other point forward of this plane if this configuration produces a greater overall width.

              In such cases, a description specifying that the device for indirect vision shall be mounted so as to conform
