Memory Upgrade
Operation
You must replace the mini-touch panel's 128KB integrated circuit (IC) with a 512KB
IC to increase the storage capacity (memory) for control pages and symbols. You will
need a Phillips screwdriver and a non-conducting flat-blade tool to slip under the IC
and pry it out of its socket.
AXT-MCA (/PB) and AXT-MCV (/PB)
Figure 249 shows the location of the IC on the AXT-MCA (/PB) and AXT-MCV (/PB)
circuit cards.

Discharge the static electricity from your body by touching a grounded object.
2.
Remove the mini-XLR AXlink connector from the rear side of the mini-touch
panel.

panels that have only 128 KB.
