PROBABLE CAUSE
•
Faulty connection
between the PBX and
telephone.
•
Faulty telephone.
•
A telephone with an A-A1
relay is connected.
•
Faulty extension card.
•
The H and L pins of
extension jacks may have
shorted.
•
If using an amplifier, noise
may be being introduced
through the cable
connecting the PBX and
the amplifier or
loudspeaker.
•
Audio level from the output
of the audio source is too
high.
•
Incorrect programming.
SOLUTION
•
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.
•
Plug the telephone into a known
functioning extension port. If the telephone
does not function, replace the telephone.
•
Use a 2-wire cord.
Set the A-A1 relay switch of the telephone
to the "OUT" or "OFF" position.
•
Exchange the card for a known functioning
one.
•
Turn the Power Switch to the "OFF"
position. Fix the shorted part, then turn the
Power Switch to the "ON" position.
•
Use a shielded cable to connect the PBX
and the amplifier or loudspeaker. A shorter
cable will introduce less noise.
•
Decrease the output level of the external
audio source by using the volume control
on the audio source.
•
Store the outside (CO) line access number
(for example, 9, 81 through 88) at the
beginning of the telephone number.
•
Turn the Power Switch to the "OFF"
position, and then back to the "ON"
position.
