7-2 Troubleshooting
PROBABLE CAUSE
Bad printed circuit board
(Extension Card).
Bad connection between
the system and extension.
A telephone with an A-A1
relay is connected.
Bad extension.
Induced noise on the wire
between the system and the
amplifier.
Excessive input level from
external music source.
Bad programming.
POSSIBLE SOLUTION
Exchange printed circuit board for
another printed circuit board.
Take the extension and plug it into
the same extension port using a
short telephone cord. If the tele-
phone does not work, the connec-
tion between the system and the
extension must be repaired.
Use a 2 wire cord.
Set the A-A1 relay switch of the
telephone to the "OUT" or "OFF"
position.
Take the extension and plug it into
another extension port that is
working. If the telephone does not
work, replace the phone.
Press the Reset Button.
Use a shielded cable as the connec-
tion wire between the system and
amplifier. A short shielded cable is
recommended.
Decrease the output level of the
external music source by using the
volume control on the music
source.
Enter the CO line access number
