Re-building the recorder 
 

Rebuilding the recorder is the reverse process.  
 
Offer up the display to the front of the unit, reconnect the display lead and feed the inverter cable through the 
rectangular hole in the mounting plate. Fit the 4 screws holding the display in place. 
 
Before refitting the bezel/touch screen assembly clean any dirt or marks form the back of the touch screen or display. 
Use a lint free cloth to clean both parts, do not use any solvents. 
 
Refit the 8 screws that hold the front bezel in place. 
 
Plug the inverter lead back into the inverter. 
 
Slide the case back onto the recorder ensuring it is fitted the right way round. The cooling slots should be at the top of 
the unit. 
 
Finally fit the four M4 screws that hold the case to the chassis.
