assembly and discard. See figure 3-6 for location
of existing standoffs.
6) Remove operators panel cable clamp and discard.
7) Fasten a ground wire to monitor chassis mounting
screw shown in figure 3-5. the other end will be
connected in step 12.
8) position shield as shown in figures 3-5 and 3-6 and
insert three new standoffs (these are provided)
through the shield and attach it to the monitor
chassis.

the shield so it will fit between it and the modem
printed circuit board after the board is installed.

up with the three standoffs on the shield.
d) Press the board into place by pushing it over the
three standoffs until it is in the mounting posi-

of the three standoffs (leave tie wrap off the
fourth standoff) and lock each tie wrap.
Installing the tie wraps ensures a locking action
