1 Disconnect the main power/system cable from the rear of the attendant
console, and remove the handset jack plug from the side.
2 Move the adjustable display to the down position to protect it from
damage while removing the BLF/CGM. Also move the volume slider
switch to the far left (see Figure 2 on page 36).
3 Place the attendant console facedown on a properly prepared work
surface, taking care to avoid scratching or damaging the top cover or
display. Remove the adjustable stand, if required.
The stand is secured with four screws. Remove the stand as a
complete assembly, and set it aside.
4 Remove the 12 fastening screws in the base of the attendant console that
secure the top cover to the console base. See Figure 3 on page 37.
Remove the two screws securing the BLF/CGM to the base of the
attendant console.
5 Holding the console base and cover firmly, turn it back over so that the top
cover is on, facing up.
6 Raise and hold the top cover to remove the single cable connector only.
The alerter cable does not need to be removed (see Figure 4 on page 38).
7 Unplug the BLF/CGM ribbon cable from the attendant console.
8 Remove the top cover and place it upside down to the left of the attendant
console.
9 Pull back the snap-fits on the BLF/CGM to disengage the BLF/CGM from
the attendant console.
10 Place the top cover on the console. Slide it back and down into place (see
Figure 7 on page 41). Reconnect all cables in the correct positions, and
make sure that none are trapped.
