MULTIFUNCTION/SPEECH INSTALLATION GUIDE
Removal/Replacement of EPROM Chip if Required
1. Remove the SS-2 card (Memory module) from its slot in the card cage. Place the
memory module on a flat surface (preferably on an ESD mat). Position the card
so that the front of the module is facing towards you (Figure 1).
Remove this chip
2. Remove the EPROM chip that is immediately to the left of the circular battery
(see Figure 1). The use of an IC chip puller to perform this step is recom-
mended; however, a small flat-blade screwdriver can be used. Place the tip of
the screwdriver between the chip and its socket, and twist the tip slightly to
begin lifting the chip from the socket. Move the tip of the screwdriver to the
opposite end of the chip and repeat. By alternating sides and lifting the chip
a small amount each time, you will eventually release the chip from its socket.
At this point, carefully remove the chip from the memory card.
3. Take the new EPROM (SD04.01) and place it lightly on the chip socket, en-
suring that the half-circle notch on the chip is positioned to the
left (see
Figure 2). Align the pins of the chip with the insertion holes of the socket.
