For best performance and compatibility, Sea-Bird recommends that customers set their computer to English language format and the use of a period (.) for the decimal symbol. Some customers have found corrupted data when using the software's binary upload capability while set to other languages. To update your computer's language and decimal symbol (instructions are for a Windows 7 operating system): In the computer Control Panel window, select Region and Language. In the Region and Language window, on the Formats tab, select English in the Format pull down box. In the Region and Language window, click the Additional settings . . . button. In the Customize Format window, select the period (.) in the Decimal symbol pull down box, and click OK. In the Region and Language window, click OK.
