6. Replacement of boot EPROMS
This installation step can be skipped for upgrade kit with p/n 171.0216
(DECADE II with s/n > 17100091)
Remove both EPROM's on control and sensor board as described in the
service manual in paragraph "Replacement of EPROM's". Replace the
EPROM's with the EPROM's provided to you in the upgrade kit. The EPROM
of the control board is located on the position (A) marked with the arrow in
figure 8. For the location of the EPROM on the sensor board see figure 4 (A).
Figure 8 Top view of control board. (A) control board EPROM.
Take precautions against electrostatic discharge during installation/
removal of the EPROMS at all time.
Both EPROMS can be removed from the board using an IC-puller or
alternatively a flat screwdriver. An IC-puller is the recommended tool. Clip the
IC-puller around the EPROM (on end) and lift it gently out of its socket. Make
sure that you don’t bend the legs of the EPROM. In case of a screw driver,
insert it between the EPROM and the socket and lift the EPROM gently bit-
by-bit out of the socket. NOTE: avoid scratching the circuit board with the
screwdriver.
