Basic Troubleshooting - Talk-a-Phone ETP-120 Series Installation & Operation Manual

9. Basic Troubleshooting

Problem
My unit does not
function at all. I cannot
call it or call out on it.
I can hear the remote
side, but they cannot
hear me.
The unit does not hang
up.
When the remote side
answers the phone, they
hear a series of tones
before being able to
speak.
The unit gets dial tone,
dials and then hangs up.
My external device is
connected to the
Auxiliary Input, but it
does not activate the
ETP-120 unit.
My phone will not
successfully dial the
second phone number if
the first one is busy or
not answered.
In order for up to six (6) ETP-120 Series Call Stations to share one analog phone line,
Model EC-6 is required.

Possible Causes
1. The phone line is not properly connected.
2. The unit has been struck by lightning or another very high voltage
source. Contact Talkaphone's Service Department.
3. There isn't enough power on the line (see Technical Requirements,
Section 1.3, p.3).
The unit is programmed to play a voice message upon answering, but
background noise or silence has been recorded. The answering point
(remote side) will hear this voice message before the unit establishes two-
way communication.
1. The unit is not programmed properly (see Software Programming,
Section 6, p.10).
2. The unit is on a phone line that does not provide (A) a hang up pulse
and (B) produces a re-order tone or howler. Consult the phone system
administrator for further assistance.
The unit is transmitting its unique Talk-A-Lert ID number. If you are using
Talk-A-Lert to identify the location of incoming calls, these tones are
required. If not, use this programming code to disable transmission of the
Talk-A-Lert ID when the call is answered: * 6
The phone line is not providing sufficient power (see Technical
Requirements, Section 1.3, p.3).
Check that the external device is providing a dry contact closure. The
Auxiliary Input on the ETP-120 unit only supports a dry contact closure.
Make sure you have programmed a secondary number in the #01 memory
slot. Reprogram #01 for good measure.
