Troubleshooting
PROBABLE CAUSE
The HANDSET/HEADSET
selector on the KX-T7130
is set to the "HEADSET"
position.
The Ringer Volume
Selector is set to "OFF".
A proprietary telephone is
connected to the port.
The corresponding line key
does not exist on the
proprietary telephone.
There may be something
wrong with a DTMF
receiver.
POSSIBLE SOLUTION
Set the HANDSET/HEADSET selector
to the "HANDSET" position.
Set to "HIGH" or "LOW".
Disconnect the proprietary telephone
and connect a single line telephone.
Program the line key. See the Flexible
Button Assignment.
