The CMS400 uses sophisticated microprocessors and digitized human voice to read your customized checklist.  Each item is professionally recorded and spoken clearly and quickly in a challenge-and-response format.  Simply select a category and proceed through that checklist.  You can repeat an item, or skip that item for later consideration.  You also have the ability to move past checklist categories -or- move instantly to a pre-determined category -or- reset a checklist category and start again.  The CMS400 speaks only when you want it to speak.  For added operational flexibility, have a remotely mounted “Advance” button installed to help take you through the entire checklist, from start to finish!
