Connecting the Terminal to Home Phone Wall Outlet.
The TX240 can be connected to a home wall phone jack to generate a dial tone service throughout
the entire home and allow users to use phones from any other home wall phone jack. Please verify
that the home wall phone jacks do not have existing active telephone service and that they are not
powered. Before connecting the terminal to home wall jack, please test with the included “Wall Jack
Tester”.
WALL JACK TESTER (PSTN Line Tester)
The wall jack tester will verify if the wall phone jack is powered by existing or previous landline phone
service.
IMPORTANT NOTE
DO NOT CONNECT YOUR TERMINAL TO A WALL JACK IF PSTN LINE IS STILL IN SERVICE.
Connecting the terminal to the live wall jack may interfere with the existing phone service
and damage the terminal.
1. Plug the tester into the wall jack.
2. If tester’s Green colored LED illuminates (ON), your PSTN line is still active and powered. In this
case, contact your existing or previous landline phone service provider to disconnect the phone
service and power.
NOTE: Alternately, 2-line cross adapter may be used to bypass the powered first phone line. Please
.see next section, using 2-line cross adapter.
3. If Green colored LED does not illuminate, the wall phone jack is not powered and you can safely
connect your terminal to wall jack.
[LED OFF – line is safe to use]
