PROBABLE CAUSE
Bad extension card.
Bad connection between the
Hybrid IP-PBX and
telephone.
A telephone with an A-A1
relay is connected.
Bad telephone.
The number of terminal
equipment exceeds the
capacity of the Hybrid IP-
PBX with the supplied AC
adaptor only.
Induced noise on the wire
between the Hybrid IP-PBX
and the amplifier.
Excessive input level from
external music source.
SOLUTION
• Exchange the card for a known working
one.
• Take the telephone and plug it into the
same extension port using a short
telephone cord. If the telephone works,
then the connection between the Hybrid
IP-PBX and the telephone 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 telephone and plug it into
another 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
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.
