10 Troubleshooting

EC-Phone keypad is not responding.

Touch <WAKE> and confirm that the green wake LED is on (upper right of keypad).
EC-Phone is not responding. No response when PHONE button is pressed.

Confirm that the green power LED is on (lower left of circuit board).

Confirm the red alarm LED is not illuminated.

If power is on, try touching the <EXIT> key on the keypad.

Touch <WAKE> then <LINE TEST> then dial a test number.

If still no response, check the speaker, phone line and call button connections.

If connections are okay, connect a handset to the telephone line. If still no dial tone, the
problem is likely with the phone line or PBX. Check wiring continuity to the telephone
room or contact the telephone service provider.
Dial tone is present but the EC-Phone does not dial.

Check the primary phone number is programmed (Command #1 - replay).

Touch <WAKE> then <LINE TEST> then dial a test number.
Dial tone is present. The unit briefly dials but gets a busy signal.

The phone is possibly connected to a switchboard which may require an 8 or a 9
followed by a pause to access an outside line, followed by the phone number, or the
switchboard may not allow outside calls. Try the Line Test feature or contact the
switchboard vendor.
Phone does not hang up when the external party ends the call.

The phone is probably not receiving a "wink" or "CPC" signal which may need to be set
in the PBX by the switchboard vendor.

If the problem cannot be solved, lower the "Talk Time" value (Command #15) to
compensate (minimum time to comply with Code is 3 minutes).

The monitoring station also has the option to hang-up the call manually by pressing
<*><#> at the end of the conversation.
Cannot call into an EC-Phone.

Check the phone is on-hook

Check the individual cab ID (Station Number) is programmed (Command #5 - replay)
and that one of the phones is set to Station Number 1.

If the EC-Phone is connected through a Consolidator, ensure that the phone has
automatically set Function #40 to "1", "2" or "3" (Command #40 - replay).
Audio related issues.

Adjust the speaker volume or the microphone sensitivity. If the increased microphone
sensitivity creates "chopping", increase the Voice Detection Threshold (Command #34)

Make sure the EC-Phone microphone hole is aligned with the panel hole (using the
template provided), that it is not blocked, that the microphone gasket is in place and the
phone is not spaced away from the panel (any gap will cause feedback).

Check the EC-Phone speaker is aligned with the panel speaker perforations.
