You will also need a #2 Phillips head screwdriver and an anti-
static wriststrap.
Performing the ROM upgrade is an easy process, but to
avoid problems, please follow these instructions carefully.
Pay particular attention to the precautions listed in the safety
summary and those which appear throughout these instruc-
tions. Any damage caused during installation is not covered
under warranty.
CAUTION
TURN OFF AND DISCONNECT ALL POWER
TO THE MPX R1 PRIOR TO INSTALLING
SOFTWARE.
Open the MPX R1
Before opening the MPX R1, put on your anti-static
wriststrap.
Remove the six (6) screws which attach the bottom plate to
the unit.
Remove the bottom plate and put it aside.
Install the IC
Referring to the illustration to the right, locate the ROM (U9).
Using the IC Extractor Tool, remove the ROM.
CAUTION
Check the ROM provided with your upgrade kit. Because the
manufacturing process leaves the pins angled out slightly
from the body of the ROM, the pins must be straightened
before insertion with the following procedure:
1. Place the ROM on its side on a static free surface.
2. Hold the body of the ROM and, exerting gentle pressure
downward, roll it slightly to force the pins into position
parallel to your work surface.
Rear
When inserting the new ROM, be careful to align it correctly,
Note that the new ROM is smaller than the socket. Align the
UN-NOTCHED edge of the ROM with the bottom edge of the
socket.
Avoid bending any pins. When the ROM is inserted, carefully
inspect each pin to be sure that it has not been bent.

CAUTION
ICs inserted backwards will be destroyed.
Incorrect insertion of ICs is also likely to
cause damage to the board.
