QuoteI have had one of your Testune units for more years than I care to admit. I was certain that I would never need the instruction book as I was so familiar with its use. UNTIL TODAY. I had a very senior moment and got lost. Thank goodness for the internet but far more importantly for a company such as yours that has the decency to publish their technical instructions on line. You have my sincere thanks - Peter from @talk21.comQuote
