Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):% @/ \5 Q$ n, R
“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.( J( _* w; E, Z# g' i
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.* I% S1 y: T, }1 F& S
That cannot be a solution because many products are too small!”5 [& v! y2 X G
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):
; E' H6 Z, ^( |8 P/ c( fLater 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.
* i b3 N c q) s5 q4 HIt 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.( q0 d4 ~: B7 |6 ]0 ~" c( s
Decision: This decision replaces 01/8 with the amended text in red:8 N9 b: e- L; {3 |9 U
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"3 G; u+ Z1 L$ K# Y

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).
