DSI Pro TEC Cooler Modifications

Modifications to the DSI Pro camera require opening the camera

and drilling holes through the back of the case for two 6-32 screws

(for added stability, 4 screws could be used) to hold the TEC/Heat

Sink and Fan assembly against the back of the DSI case. Note:

This will void the camera warranty. Use a 2.5 mm Allen wrench

and carefully open the camera from the front by removing the hex-

head screws in the corners. Be careful not to tear or stretch the

rubber gasket (see Figure A-6).
