Remedy
Check that power is on and cables are plugged
in.
See "Changing voltage and frequency settings"
on page 18.
Connect controller.
Install a phase-reversing cable between the
controller and the first fixture on the link.
Inspect connections and cables. Correct poor
connections. Repair or replace damaged
cables.
Insert termination plug in output jack of the last
fixture on the link.
Check fixture address and protocol settings.
Bypass one fixture at a time until normal oper-
ation is regained. Do this by unplugging the
XLR in and out connectors and connecting
them directly together. Have the fixture ser-
viced by a qualified technician.
Install a phase-reversing cable between the fix-
tures or swap pins 2 and 3 in the fixture that
behaves erratically.
Disable effects feedback (page 10). Contact
Martin technician for assistance.
Disconnect fixture. Check ballast and trans-
former settings and correct if necessary.
Disconnect fixture and replace lamp.
Disconnect fixture and install lamp.
Allow fixture to cool.
Reduce ambient room temperature.
