Procedure 1
Removing the Busy Lamp Field/Console Graphics Module
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 17).
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 18 on
page 64.
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 19).
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 23 on page 69). Reconnect all cables in the correct
positions, and make sure that none are trapped.
11 Ensuring that the volume slider is fully engaged in the correct slider,
hold the top cover and console base firmly together. Turn the assembly
upside down (see Figure 24 page 70).
12 Reinsert the 12 screws that secure the top cover to the console base
and tighten.
13 If required, replace the adjustable stand.
