SOLUTION
•
Exchange the card for a known working
one.
•
Take the telephone and plug it into the
same extension port using a short tele-
phone cord. If the telephone works,
then the connection between the PBX
and the telephone must be repaired.
•
Use a 2-wire cord.
•
Set the A-A1 relay switch of the tele-
phone to the "OUT" or "OFF" position.
•
Take the telephone and plug it into an-
other extension port that is working. If
the telephone does not work, replace
the telephone.
•
Connect an additional AC adaptor.
•
Press the Reset Button (refer
to "4.1.4 Using the Reset Button").
•
Turn off the power switch, and then turn
it back on.
•
Turn off the power switch, and then un-
plug the PBX. After 5 minutes, plug the
PBX back in, and turn the power switch
back on.
•
Use a shielded cable as the connection
wire between the PBX and amplifier. A
short shielded cable is recommended.
•
Decrease the output level of the exter-
nal music source by using the volume
control on the music source.
•
Switch the calling mode to ring-calling.
•
Set the LCS mode to "Private".
