Removal and re-fitting the Mother Board
Once the case is removed, loosen the screws that hold all the I/O boards and power supply into the case. Pull each of
these cards towards the rear of the recorder so that their connectors disengage from the Mother Board. (The mother
board stands vertically inside the recorder). The boards do not need to be completely removed to allow access to the
Mother Board.
Disconnect the speaker cable from the mother Board.
Once all cards have been disengaged the Mother Board can be pulled upwards to unplug from the processor board.
The Mother Board can now be removed.
