    DOC. MIE12093 Rev. 1 Page 4 of 52 SHORT FOREWORD Dear T/1000 user, I often wondered why the user’s manual is not very much used, even if it includes valuable information. As me too I am a user of such manuals, the answer I have given myself is that valuable information are concealed somewhere in the thick thing, and I do not have time to waste to find it.
