A telephone with an A-A1
relay is connected.
Something is wrong with
the extension.

Wrong programming.
An extension (H, L) port 01
through 08, 09 through 16,
or 17 through 24 may have
been shorted.
Exchange the printed circuit board
with another printed circuit board.
Take the extension and plug it into
the same extension port using a
short telephone cord. If the
telephone works correctly, the
connection between the system and
the extension must be repaired.
Use a 2 wire cord.
Set the A-A1 relay switch on the

Take the extension and plug it into
another extension port that is
working. If the telephone does not
work, replace the phone.
Turn the Power Switch “OFF” and
then “ON”.
Use a shielded cable as the
connection 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 an exchange line access
number (9 or 0, 81 through 86) in
programming.
Turn the Power Switch “OFF”.
