Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):$ l) G) ?! X9 c
“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.6 I; v2 f2 `2 _8 e/ ^ m ?8 d- R
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.) G) P, {8 m& n
That cannot be a solution because many products are too small!”1 H8 S2 O: H* B% }( V) j
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):
% l/ d) y# {% }6 ]% QLater 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.

Decision: This decision replaces 01/8 with the amended text in red:

The user instructions must then have a listing of manufacturers and models of the relevant power supplies.
