Notes.
1. To disconnect the display flex-circuit, it may be necessary to remove the I/O module board in Slot D (if fitted).
2. SM2000 main boards manufactured before March 2005 have a 4-pin tochscreen flexi-circuit and a 4-pin connector block. Main boards
manufactured from March 2005 onwards are fitted with a 6-pin connector block. When reconnecting the touchscreen flex-circuit to a
main board equipped with a 6-pin connector block, ensure it is connected to the
4 pins nearest the front of the recorder.
Caution. When fitting a main board, ensure it
locates correctly in the lugs on the chassis
base.
