Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):( B M5 J8 t! l* L2 u' D
“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.
1 w1 R" l1 U" BWe 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 n3 F2 q7 [9 d$ sThat cannot be a solution because many products are too small!”
* p5 y& b# C: e# gOSM/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):
