Replacing the EPROM
fig. 41: Control circuit board
The EPROM B 11 contains the operating software (firmware) of the SCPC System. It needs to be
replaced to perform an update. Observe the following instructions when replacing the EPROM:
◗ Always use suitable removal and insertion tools so as not to bend the contacts.
◗ Avoid static charging (and hence damaging the electronic components) by suitable earthing
measures.
◗ When inserting the new EPROM, ensure the correct alignment (notch pointing towards centre of
board).
