If ''Crash Detection'' is enabled, it monitors acceleration on each axis which helps detecting an accident. ''Threshold'' and ''Duration'' values are set depending on the impact that is required to be detected. {{{model|FMB640}}} can detect events ranging between a slight tapping on the device (Threshold = 100 mG, Duration = 1 ms) and a severe accident (Threshold = 4000 mG, Duration = 5 ms). | If ''Crash Detection'' is enabled, it monitors acceleration on each axis which helps detecting an accident.
