Inserting a Voice Terminal Module
Make sure the power is off, the control unit is not plugged into the power source, and the covers are off. Then locate the slot between the voice terminal module and the line module already in place. Align the edges and install the voice terminal module using the same procedure you used for inserting the line module. Check to see that the module is securely in place. See Figure 12 at (a).
When two line modules and two voice terminal modules are installed in this system, the control unit is at full capacity as shown in Figure 12 at (b). As designed, empty space remains to the left of the first voice terminal and to the right of the second line module.

Once you have installed all modules, go on to the next procedure, "Connect
the Control Unit to the AC Outlet."
