Exnomad,
Did/has it ever occurred to you to look up what you are supposed to read back, and how to read it back, and just do that.
What you have said in your post is wrong, another example of perpetuation of error by ignorance.
There is nothing like the facts to get your facts straight.
At least, in this day and age, all such information is easily accessible, so that is no excuse.
Tootle pip!!
