Electronics & Innovation Ltd., (hereafter E&I) warrants for the period of one year from the 
date of original delivery, each unit to be free of defects in materials and workmanship. For 
the period of 12 months E&I will, at its option, repair or replace defective parts so as to 
render  the  unit  fully  operational  such  that  it  performs  according  to  the  original 
specifications; free of charge to the original purchaser.  
 
Should warranty service be required, the unit must be returned to E&I, freight cost to be
