Figure 11: CPU and Connector PCBs
The latch at either end, shown by arrows in fig. 11, can be released and the
flat ribbon cable removed, this will then free the Connector PCB.
3.4.9 CPU PCB removal
To remove the CPU PCB [fig. 13, 008] one Torx screw [014] must be removed and
the three connections from the battery compartment must be unsoldered very
carefully.
Once the screw [014] is removed the connections can be unsoldered (3 connections
as shown in fig. 12) and the CPU PCB removed, this must be done with care to en-
sure no damage occurs to the PCB or the battery connecting wires.
