There are two series A and Series B. And I already tried to search the manual but don't find the answer. Someone, please help me to explain the difference between two series. Really appreciated. Thank you! [/INST] Welcome to the Forum ! When a product maintains the same part number and only the series changes, it reflects changes in manufacturing process and/or parts used in its assembly. These changes maintain or improve the quality and performance of the product and should not affect its performance. In order to understand which differences are between two series of a product, you can try to post specific item codes. Sometimes products of different series are directly replaceable, sometimes not. - fuzzy logic In order to enhance the reputation of the Forum's contributors, please rate the replies you got and remember to close the thread clicking Choose as Best Answer button over the solving answer.
