Troubleshooting Table A-1 Troubleshooting Solutions Symptom The image does not display correctly. The image is disturbed (drop frame, etc) Audio troubles Audio fragmentation. No audio. 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. 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. 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. • 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.
