Important Notes:

️· Units: The document doesn't *explicitly* state the units for the dimensions (A, B, C, etc.). However, based on the values, it's highly likely they are in millimeters.
️· Ranges: Some characteristics have a range of values. This indicates that the specific value depends on the exact model (SEF301C, SEF302C, etc.).
️· Data Source: This data is based on a scan/OCR of a document. There may be minor errors or inconsistencies due to the conversion process.
