Replace the host PC unit

Remove and replace the host PC unit — the computer mounted in the CPU BOX cabinet that controls the entire Activion16 system and performs image-processing operations such as 3D processing — on either of its two documented hardware generations, PX74-08766 Gr.4 or PX74-09549 Gr.3. The removal procedure is identical for both generations.

Avoidance: Hold the unit securely throughout the pull-out motion

NOTICE

Hazard: Replacing (discarding) the USB LAN module when replacing the host PC unit itself

Consequence: Loss of the option hardware/license key that identifies the registered user on this system
