We have the VVX 400 and are trying to hook up the color expansion module with it.  The VVX 400 is version 4.1.4.7430.  When we first plug in the expansion module, all the green and red lights light up after that the screen goes dark and does nothing.  Has anyone else had similar issues with the expansion module with this VVX400 phone?
