Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):0 S- Z4 w- H7 \8 i
“OSM decision 01/8 requires markings on the product (e.g. "Use only power supplies listed in the user manual / user instruction." or “For applicable power supplies see user instruction”). Furthermore such sentences shall be in the languages acceptable to the country where the product will be used.% Z* V0 m: ^1 x" J2 Z. g" p. n
We cannot assume that all people speak or understand English and therefore it is necessary to put nearly all languages of such relevant safety instructions on the product.
! z2 n1 X. D! O+ e2 p0 IThat cannot be a solution because many products are too small!”2 r {: J; }3 K, Z6 F9 n4 b
OSM/EE-2007 agreed to use instead of such instructions (sentences) on the product, international accepted symbols like these both marks (ISO 7000-0434 and ISO 7000-1641):" D( V h( F+ U* }0 d$ }
Later it was confirmed by TC108/MT2 that the book only can be used as an alternative. See explanatory notes below. Based on this it is proposed to revise decision 01/8 as amended with red text under the decision below.
# m! U1 i; C# z2 u( }; J: F* TIt may be considered that the Decision 99/2, requiring marking of manufacturer and model of the power supply on the product, is too stringent in light of sub clause 1.7.2.

A Class III equipment with an enclosure made of HB material and using a non-special connector for the a.c./d.c. input has to have a marking stating the following: "Use only power supplies listed in the user instructions"

"For applicable power supplies see user instructions". This statement shall also be in the user-instructions.

As an alternative to the text on the product, it is acceptable to use both the symbols ISO 7000-0434 and ISO 7000-1641. The book alone is also sufficient (ISO 7000-1641).
