Greg: Use the power (toggle) switch on the back to turn it off for a few seconds (6 or so) then switch back on. You may need to restart the computer after you restart the MS. --Alison -------------------------------------------------------------------------------- Alison Pye .

A recent power failure has left our finnigan 252 not wanting to communicate with the computer. ISODAT is loaded and trying to communicate but we get a "wait micro processor reset" message in the upper right hand box of the ISDAT screen and a "error 502" "Module 7" non fatal error box. Is there some sort of reset button in the MS that kicks off during power surges? Any ideas?
