I'm trying to call Dynotech under 248- 362-2777 right now, but nobody is answering? Is today (Friday) already a public holiday, due to the fact that 4th July falls on a Saturday ? Or has the Dynotech's number changed ? I also found in my old files another phone no. 908-704 8536, but that seems to be somwhere completely else laocated? Jochen
