STEREOTEST BOOKLET CARE INSTRUCTIONS:
Please bring your stereotest booklet to room temperature before it is used. Immediate use right out of the box when outside temperatures are cold may cause the vinyl material to crack. Also please do not bend the booklet in half so as to avoid breakage. When you take extreme care of your booklet, it should last you many years.
