Replacing system modules is similar to how you originally installed modules into the control unit.
The procedure varies slightly between the stand-alone/2-slot carrier configuration and the 5-slot
carrier configuration.

CAUTION:
Before starting, verify that you have batteries installed in the processor module by viewing
the display of the telephone at extension 10.
To replace a module or modules in a stand-alone or 2-slot carrier configuration:
1. Remove the power cord from the wall outlet.
2. Check the slack in the wires. If there is not enough slack to remove the module without pulling
the line and extension cords free, label and disconnect the wires before continuing.
3. Do one of the following:
■
For a stand-alone configuration, remove the screws at the top and bottom of the processor
module, and remove the module from the wall. Go to Step 8.
■
For a 2-slot carrier configuration, remove the long screw at the bottom of the modules
(see
Figure 10-6 ).
