"Disconnect" or "Comm Fail" message in console LCD display
Affects M4217B, M4118, M4018. Check the following:
• Check the rear of panel's CCE LIVE LED and CIC cards CONS LIVE LED. If one
or both are not illuminated it's likely a data wiring problem.
• DATA wiring of CI and IC pairs. Check both the CCE position punch-block end
and the DATA port of the RJ-11 duplex wall jack.
• The data is RS-422 protocol and is polarity sensitive. Verify correct pins and
polarity.
No audio out of either speaker on console
Check the following:
• Check if affecting specific channel or any channel. If single channel, try another
channel to isolate if channel card or console issue.
• VU meter deflection (SEL only). If there is meter movement on receive, it means
audio is present at the console itself.
• Verify no jackbox/TRHI with headset/handset in jack. Check that HEADSET
button isn't active (red LED illuminated if active).
