To change the CPU clock speed, remove the CCM and place the module on a flat
surface with the front panel towards you. The 7249 or 7835 main processor board is
the large sub-board on the right or bottom of the module. Jumpers J1 to J5 are
located below U1 (the 80C152JA-processor chip). Use the links provided to set the
clock speed.
To use motor faders or SAM/Séance, Fast Copper is required.

When the console is first powered up, programmable modules may be set to power
up in ISOLATE mode or in NOT ISOLATE mode. This option is user selectable by
setting links on the motherboard. The factory setting is NOT ISOLATE.

Place the CCM module on a flat surface so that the front panel is facing you and the
mother board is laying on the surface. Locate the three way male molex connector
CN26. This can be found on the mother board near the EVENT LEDs LD12 and
LD16, close to the front panel. CN26 is surrounded by a white rectangle and is
clearly labelled “POWER-UP STATE” (see fig 2-4 for details).
