3.2.2  Mounting a GFC-2020 Accessory Lateral Output Deflection Mirror 
The  GFC-2020  accessory  is  a  Lateral  Output  deflection  mirror  which  helps  to  position  the 
scanner body in a different orientation with respect to the code, for limited space applications. 
CAUTION 
Subzero  model  scanners  must  not  be  opened  in  an  uncontrolled 
environment. 
The installation of the deflection mirror is very easy. 
1.  Make sure the device is not powered. 
2.  Remove the original 0° scanning window 
from the scanner by unscrewing the two 
cover screws.

other optical components; otherwise the  performance of the reader will be 
reduced. 
3.  Clean  the  mirror surface and  reading  window  with  a clean  soft  cloth  and  alcohol  before 
closing the scanner. 
4.  Mount the  GFC-2020 accessory so  that  the opening  face is at 90°  with  respect  to the 
scanner body. Tighten the two cover screws.
