pcb aSSEMBLY #1540048 (sCHEMATIC 1540049) REQUIRES AN UPGRADE TO THE RESET CIRCUIT. tHE UPGRADE CONSISTS OF:

1) component changes:

r25	cHANGE tO	6.8k OHM,	1/4 w, +/-5%
r57	aDD	220 OHM,	1/4 w, +/-5%
r58	aDD	2k OHM,	1/4 w, +/-5%

2) cut CIRCUIT TRACE NEAR ua1 (sEE DIAGRAM)

3) install jumper wires:

between:	ua1 PIN 8 AND ub1 PIN 5
	ua1 PIN 9 AND cr4 aNODE
	ub1 PIN 6 AND ud3 PIN 5 ON back OF BOARD

4) cut CIRCUIT TRACE BETWEEN cr7 aNODE AND ud3 PIN 5 ON back OF BOARD.
