4.1 The symbols shall be such that, when viewed by the rider, from their normal seated position or normal operated position, they are recognizable as shown In AnnexcsA to 0.
4.2 The symbol shall be pLaced on, or adjacent to, the control or tell-tale to be identified, Where this is not possible, the symbol and the control or tell-tale shall be joined by a continuous line as short as possible
4.3 The symbols and signs shall be as given in Annexes A to L and Annex N. Additional symbols are given in Annexes M and 0. Minor deviations to the symbols and signs are permitted, provided they are necessary to reproduce an accurate representation to the rider’s line or sight.
NOTE Additional annexes can be Included In future editions of this document If necessary.
4.4 In developing the symbols and signs shown in Annexes A to Q, legibility factors such as line thickness, gaps between lines, symbol and arrow shapes, etc. were carefully considered. Modifications that improve legibility are permitted in the circumstances specified in 4.4d. 4A2 and 4AJ. When modifying symbol elements, the graphic designer should consult I EC 80416-1, ISO 80416-2, IEC 80416-3, and ISO 80416-4.
4.4.1 Limitations inherent in some reproduction and display technologies can require increased line thickness or other minor modifications of symbols. Such modifications are acceptable provided the symbol remains unchanged in its basic graphical elements and is easily discernible by the operator.
4.4.2 Additionally, to improve the appearance and perceptibility of a graphical symbol or to coordinate with the design of the equipment to which it is applied, it can he necessary to change the line thickness or to round off the corners of the symbol. The graphic designer Is normally free to make such changes provided that the essential perceptible characteristics of the symbol are maintained.
4.4.3 The graphic designer may render a symbol in either outline or solid form unless this is otherwise prohibited by the symbol description.
4.5 The vehicle shapes shown in this document are not intended to he restrictive. Modifications to
vehicle shape may be introduced by designers in order to better represent the true exterior shape of a
given vehicle. Except for vehicle shape, no other symbol element shall be changed, except as provided in
4.4 or in the specifIc symbol’s description.
4.6 If, in a .symbol, a vehicle or parts ofa vehicle are shown in a side view, a vehicle driving from right to left shall be used.
4.7 For actual use, all symbols shall be reproduced large enough to be easily discernible by the operator. See IEC 80416-3 for guidelines on the proper sizing of symbols. Symbols shall be used in the orientations shown in this document unless otherwise noted for individual symbols.
4.8 For most controls, a light symbol on a dark background is preferred. Displays may use either a light symbol on a dark background or a dark symbol on a light background, depending on which alternative provides the best visual perception. When a symbol image is reversed (for example black to white and vice versa), it shall be done for the entire symbol.
4.9 Each symbol used for the identification of a tell-tale, control or indicator shall stand out clearly against the background.
410 Letters and numerals may be used as symbols, but are not registered by ISO/TC 145, Graphical symbols, or published in Iso 7000. For example, the letters ft. N, I), listed as symbols
4.11 Failure or malfunction may be conveyed in two ways:
a) Base symbol combined with a colour code according to
b) Base symbol combined with failure symbol
