Table A-1 Troubleshooting Solutions
Possible Cause
• There could be noise influences
caused by power grounding, case
grounding, or cable shield wear.
When not using groundings or
shielded cables (STP cable), noise
influences may easily occur.
• The encoder may be installed in a
place subject to high-frequency
noise. When the encoder is
installed near fluorescent lamps, a
transformer, or a CRT monitor, it
may be influenced by
high-frequency noise.
• The cables connected to the
encoder could be wired with
high-voltage power cables. When
the cables are wired within 10 cm
of high-voltage power cables, etc,
there might be noise influence.
Temporary network trouble (a broken
wire, a broken connection...) may be
the cause.
Note If this happens frequently, you
may need to change your
network connections.

• The audio device is not correctly
connected to the AUDIO OUT
connector.
• The audio input and output levels
do not match. The AUDIO OUT on
the encoder is the LINE OUT.
• The setting for "AUDIO OUTPUT"
on the AUDIO page of the encoder
is set to OFF.
• The audio received by the
recorder is muted.
If you require technical support, please contact Honeywell Technical Support (see the back
cover of this guide for contact information).
Possible Solution
• Use grounds or shielded cables.
• Install the encoder away from
devices such as fluorescent
lamps, transformers, and CRT
monitors.
• Wire the cables more than 10 cm
away from high-voltage power
cables, etc, or wire them
separately.
• Wait to see if the software recovers
automatically.
• Try reconnecting if communication
has been disconnected.

• Correctly connect the audio input
connector on the monitor or
speakers to the AUDIO OUT
connector of the decoder.
• Connect the microphone amplifier
to the LINE OUT.
• Check the settings on the AUDIO
page of the encoder.
• Release the muting.
