from the casework. For finger marks / grease, use a soft, clean 
lint  free  cloth,  lightly  moistened  with  a  solution  of  warm  water 
and  mild  detergent.  Do  not  use  any  alcohol  or  solvent  based 
cleaning  products,  as  they  may  damage  the  finish  of  the

estimates for the lifespan of the IO Limited is within the region 
of  1000  to  3000  hours,  depending  on  and  not  limited  to  the 
factors mentioned above.
