Removal and re-fitting the Expansion Board 

If the recorder already has an expansion board fitted,  loosen the screws that hold all the I/O boards into the case. Pull 
each of these cards towards the rear of the recorder so that their connectors disengage from the Expansion Board. (The 
Expansion  board  stands  vertically  inside  the  recorder).  The  boards  do  not  need  to  be  completely  removed  to  allow 
access to the Expansion Board. 
Disconnect the power supply cable from the power supply module. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
Once all cards have been disengaged the Expansion Board can be pulled upwards to unplug from the processor board. 
The Expansion Board can now be removed.
