Replacing PROMs
Read “Propaq Encore Software” on page 47.
The PROMs require a special removal tool to replace them. ( “Required Tools” on
page 48.) To prevent damage to the PROM sockets, do not use any other tools.
Do not remove the PROMs from the Analog and Digital board. The following instructions
describe how to replace all other PROMs:
• To remove the PROMs, insert the fingers of the PROM removal tool into the slots
at two corners of the PROM and pull out the PROM, while squeezing the legs
against the PROM.
• To load the new PROM, align the beveled corner of the PROM with beveled
OUTSIDE corner of the socket. Carefully press the new PROM into place.
Caution The PROMs can be damaged by static discharge. Work only at a static-
protected work station.
