.. In case you have misplaced your owner's manual ... "
I detect a hint of sarcasm here, but I want to second the motion.
Recently I made a post observing that posters have increasingly ceased to use the extensive "search" systems available in the RR website.
In a similar vein, just this morning, I was contemplating a similar post concerning user manuals. It seems that every month, the number of questions asked on the Forums that "should" be answered in the manuals are noticeably increasing.
I know I am an unusual "nut-case", but in the case of reasonably valuable products, I will read the manual/s (cover to cover) THREE TIMES before installing batteries or plugging into a wall socket. In the case of large extensive manuals, this can result in multiple days delay in my first use of the product.
Actually, many posts here resemble those I would expect from someone who found the device on the street, or stole the item, and has no clue what the device is, or what it is used for.
