I have a question regarding to formal phrase "in manner hereinafter mentioned".
I need to make a remark in the end of the sentence that the detailed information regarding that question is elsewhere in the document. Though I cannot point the precise clause of the document because it has no determination.
So I want to use a phrase that say to a document reader that there is the detailed information herein but the reader need to look for it by themselves.
Is the phrase "in manner hereinafter mentioned" good for the official document context?
For example here is the sentence:
When your work with the system is done, make sure to disconnect the cables and turn off the system (in manner hereinafter mentioned).
I will be grateful for any assistance!
