=== Low EO Signal / No Signal ===
If [[NeoScan]] optical mainframe is on, yet, the EO signal is too low or there is no signal (Figure A-II.2), then
.
⢠The probe is not connected to [[NeoScan|Neoscan]] optical mainframe.
⢠<ul><li><p>The probe is not connected to [[NeoScan|Neoscan]] optical mainframe.</p></li><li><p>Or the probe is defective.</p></li><li><p>⢠Or the cables are lossy or defective.</p></li><li><p>⢠Or operating environment is too noisy. </p></li><ul>
Therefore,
1. <ol><li><p>Check the connectors.</p></li><li><p>2. Check the cables.</p></li><li><p>3. Inspect the probe. </p></li><li><p>4. If all the connectors and cables are fine, and still there is no signal, try another probe</p></li><ol>
