Remove the first line cord of the old module and
A)
connect it to the first line jack on the new
module.
B) Repeat for the other lines and extensions, one at
a time. (We suggest the "one-at-a-time"
approach because it's too easy to lose track
of the wires if you unplug several at once.)

A)
Connect the AC power cord to the 206 module
on a system with one module, or to the
module connector on a system with two
modules. Press firmly until it clicks into place.
(If you also unplugged the cord from the wall
outlet, plug it back in now.)
On a PARTNER 220V system, move the on/off
switch to the "on" position ("l").
B) After replacing the modules and connecting
power, check the green LEDs on the fronts of
the module(s). If the lights are lit, the system
is operational. If not, see "All Phones Dead:
No Dial Tone or Lights" in Chapter 6,
"Troubleshooting."
