求翻译：1. 独创灵敏度自动调整系统：灵敏度在检测到标签信号后自动提升（提升幅度共4级，可通过跳线选择）持续10秒（或30秒）后， 如没有再检测到标签信号则自动降低到基准灵敏度，可以很大程度减少干扰信号导致系统误报的情况，并可提高系统的灵敏度。是什么意思？

1. the original sensitivity automatic adjustment system: sensitivity label signal automatically after the upgrade has been detected (raising a total of 4 levels, can be selected by jumpers) for 10 seconds (or 30 seconds), if no label is detected signal down to a baseline sensitivity, can greatly reduce interference signals cause the system to cases of false positives and improves system sensitivity.
