Schematics are at http://www.eecis.udel.edu/~mills/database/8170/. You 
can find the DIPswitch, eyeball the component ID and go find it on the 
board. Send it T to wake it up. The * means it's not synchronized. I 
hope you got the antenna/preamp; it doesn't work without it. Also be 
aware the heavier UPSes produce so much RFI that we have had to stand 
down both of our 8170s.
