Ryobi IR thermometer instructions

A post for posterity, in case I loose the instruction manual for my Ryobi IR Thermometer Model SW-638E, a Christmas present from Sally.


It can measure temperatures of -20 to +315 degrees Celsius However, for the lower temperatures it can take 10-15minutes to adjust. For best accuracy the objects have to be under 2 feet away.
