repaired.
Use a 2-wire cord.
Set the A-A1 relay switch of the
telephone to the "OUT" or "OFF"
position.
Take the telephone and plug it into
another extension port that is working.
If the telephone does not work, replace
the telephone.
Press the Reset Button (refer to "4.1.4

Turn off the power switch, and then turn
it back on.
Turn off the power switch, and then
unplug the Hybrid IP-PBX. After 5
minutes, plug the Hybrid IP-PBX back
in, and turn the power switch back on.
Use a shielded cable as the connection
wire between the Hybrid IP-PBX 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.
Switch the calling mode to ring-calling.
Set the LCS mode to "Private".
