Richard, I have the same problem, but I figured out the Tune password (after much trying). Not sure if I should make this public, so I'll email you offlist. However, what to do after that is still a bit of a mystery. There are options to set a temp and calibrate (a sensor), and a "start" button, which fires up the conveyor/fans (but the oven does not heat up) and has a flashing "tune" button, but does nothing. Perhaps you can figure it out. --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/ContentPage.aspx?Pageid=E-mail-Forums for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
