MTH TIU and Handset Upgrade Question

Hi did you check your fuses inside the tiu ? if the fuses are ok the tiu might need a minor repair to correct your problem !

I  recently had my 2 MTH DCS TIU's and handsets upgraded with the latest software. I tried to hook them up this past Saturday and found no power coming from the variable voltage outputs. I tested the transformer terminals and the ends of the cables leading from the transformer to the variable voltage inputs with my volt meter. There was full power at both locations ruling out the transformer and the cables as the problem. Is there a bug in he latest MTH upgrade? Have any of you had the same problem? The fixed voltage outputs work well.

Thanks for any information you can provide.

How are you using the variable outputs?  If they are truly set as variable you'll most likely have to select them using the TR button on the remote if you haven't tried that already.
