Troubleshooting
PROBABLE CAUSE
The HANDSET/HEADSET
selector on the KX-T7030,
KX-T7130, KX-T7330 or
KX-T7033 is set to the
"HEADSET" position.
The Ringer Volume
Selector is set to "OFF".
A proprietary telephone is
connected to the jack.
The corresponding CO
button does not exist on the
proprietary telephone.
There may be something
wrong with a DTMF
receiver.
POSSIBLE SOLUTION
When the headset is not used, 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 CO button. See the
Flexible Button Assignment.
