damage.  If  damage  is  found  or  suspected,  please  notify  the  carrier  at  once  and  then  contact  your 
dealer.  The DaySequerra M4FM-HD is shipped in one carton, which contains: the M4FM-HD unit, and 
an AC power cable. 
 

We  strongly  encourage  you  to  save  the  shipping  carton  and  shipping  materials  supplied  with 
your M4FM-HD.

 They are specially designed to properly protect your M4FM-HD, and in the event that 

you need to return it for service, only these OEM shipping materials can ensure its safe return to our 
factory.

M4FM-HD’s  IEC320  power  entry  module  to  an  AC  mains  outlet  with  a  functional  earth  ground 
connection.    The  M4FM-HD  has  been  set  at  the  factory  to  operate  at  120VAC  unless  otherwise 
specified  on  the  shipping  carton.  The  M4FM-HD  export  version  is  configured  for  240VAC  operation.
