To remove the acquisition board
The following illustrates how to remove the Acquisition and
Dual inverter printed circuit boards.
1 Using a TORK T6 driver locate and remove the 4 screws
on the front of the instrument (4 Channel version).
2 Disconnect Inverter, keyboard and display cables. Note
locations for re-connection. It should be noted that cables
can be removed from cable clamps at this time as well.
The cable restraining pads that affix the display cable to
the front deck are adhesive and great care should be
taken when removing them so as not to damage the cable.
