17  LAST  FUNCTION  MEMORY 
l  This  unit  is  equipped  with  a last  function  memory  which  stores  the  input  and  output  setting  conditions  as  they  were  immediately  before  the 
power  is switched  off. 
This  function  eliminates  the  need  to  perform  complicated  resettrngs  when  the  power  is switched  on. 
l  The  unit  is  also  equipped  with  a  back-up  memory.  This  function  provides  approximately  one  week  of  memory  storage  when  the  main  unit’s 
power  switch  is off  and  with  the  power  cord  disconnected.
