The pump owner's manuals are not written by the same folks who write the instruction manuals for your VCR and computer! Believe it or not, there is some useful information in the manual. They are designed to be easily understood by the "average" pumper.
When you first start pump therapy, it really is a good idea to carry the manual with you in your book bag, purse, lunchbox, etc. If you need to refer to it, it's there. If you need it and don't have it, then you're just plain stuck.
Brush up on the information in the manual from time to time. Eventually, when you reach "pump veteran status" you will find that you don't need to refer to it often (but don't forget where you put it, just in case)
