You can trigger the instrument by gently bumping the instrument so that it triggers. The tiny yellow LED labeled “event” will light for ~1-2 minutes indicating that data are being recorded. Then, the blue LED labeled “link” will light briefly indicating that communications have been established with one of the servers and the data are being uploaded. In a few minutes an image of the accelerograms from your instrument will appear at this website. If the instrument is malfunctioning, the USGS will notify you about replacing it.
