Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
3 s6 W9 j* w/ D2 X/ |' W; \“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.) i, |! A" d C# f6 T
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.4 p/ z" e( O2 G0 z; C& }
That cannot be a solution because many products are too small!”+ L* C9 N' x, j4 ^. 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):2 r5 K: W' c+ t% ?: Q
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.8 V5 O: c2 w. ~, x# W& t2 a7 a
It 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 1.7.2.1 x3 s3 c3 c& h$ I0 q# p% k4 b
Decision: This decision replaces 01/8 with the amended text in red:' N7 V# _- [8 ~& y( w- D' I
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"9 [8 M B% j% H3 W. H2 Q/ T$ }! x

"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).
