Replacing System Modules

1A) To power down the system, unplug the power cord.
On a PARTNER system with an on/off switch,
move the switch to the “off” position (“O”).
B) If you have a 1-module system, simply replace
the module. Go to Step 4B.
If you have a 2-module system, remove the
screws from the module connector. Pull the
module connector off the modules. Remove
the long screw at the bottom of the modules.
2Slide off the module furthest from the wall—without
detaching the line and phone cords. If you are
replacing the module furthest from the wall, go to
Step 4; if you are replacing the one closest to the wall,
go to Step 3.
3A) Remove the screw holding the top of the module
to the wall.
B) Remount the new module as described in Step 2
on page C-8.

Reinstall the second module and module
