PROBLEM
PROBABLE CAUSE
SOLUTION
Extension telephone does 
not function.
Faulty connection 
between the PBX and 
telephone.
Plug the telephone into the same 
extension port using a short telephone 
cord.
 
 If the telephone functions, then the 
connection between the PBX and the 
telephone must be repaired.
Faulty telephone.
Plug the telephone into a known 
functioning extension port. If the telephone 
does not function, replace the telephone.
A telephone with an A-A1 
relay is connected.
Use a 2-wire cord.
 
Set the A-A1 relay switch of the telephone 
to the "OUT" or "OFF" position.
Faulty extension card.
Exchange the card for a known functioning 
one.
Proprietary telephones 
(PTs) connected to 
extension jacks do not 
operate, but single line 
telephones (SLTs) do.
The H and L pins of 
extension jacks may have 
shorted.
Turn the Power Switch to the "OFF" 
position. Fix the shorted part, then turn the 
Power Switch to the "ON" position.

external pager 
(loudspeaker).
If using an amplifier, noise 
may be being introduced 
through the cable 
connecting the PBX and 
the amplifier or 
loudspeaker.
Use a shielded cable to connect the PBX 
and the amplifier or loudspeaker. A shorter 
cable will introduce less noise.

Background Music) is 
distorted.
Audio level from the output 
of the audio source is too 
high.

Improper operation other 
than the above.
Turn the Power Switch to the "OFF" 
position, and then back to the "ON" 
position.
