2. Once you've opened your side of the NID, you'll see one or more sets of screw
terminals inside. Each will have a short piece of telephone wire coming out of it
with a phone connector on the end plugged into a corresponding jack. If there's
only one line coming into your house, you'll most likely have only one set of screw
terminals. To disconnect from the phone company, simply unplug each of the
short telephone wires from its corresponding jack.

3. Next, you need to make it obvious to others such as phone company technicians
that you've unplugged the house phone wires on purpose and that they shouldn't
undo your modifications without risking damage to your inside equipment.
Start by wrapping the end of each of the telephone wires you just unplugged
with electrical tape so it can't be plugged back in without unwrapping the tape.
Then, clearly label the inside of the box with a message that says something like:
"Do not reconnect! May cause damage to inside equipment!" Your wireless service
provider may supply you with a sticker to place inside the NID to alert the phone
company technician why you disconnected your house wiring. No matter how
you choose to label the box, be sure it is clear, written in water proof ink and easy
to read.

Step Two — Confirm the Line is Disconnected
IMPORTANT: After you've isolated your home phone wiring from the phone
company's, it's important to confirm the line is disconnected before
installing your TX240G wireless terminal.
Go back into your house and pick up a phone that's plugged into a
jack that previously worked. You should hear absolutely nothing.
If the line's not dead, go back and check your work. If your work
looks correct and the line's still not dead, it means that voltage is
somehow still being carried on the home wiring and it's not safe for
you to proceed any further. Consult a professional electrician or
telephone technician for help.
Step Three — Connect Your TX240G Wireless Terminal
If you've successfully isolated your wiring and you've confirmed the line is dead, the
hard part's over. It's time to connect to your TX240G wireless terminal.
Simply plug your TX240G wireless terminal into any telephone wall jack using a
standard telephone cord. Finally, plug regular phones into the other jacks in your
house. Telephone jacks are wired in parallel, so when you plug your phone adapter
into any working jack, it will spread the signal to the other jacks in your home.
Also the TX240G has two jacks on the back of the unit. These two jacks are bridged
together so you can connect to the wall jack and a phone next to the terminal.
