The system normally operates without any operator intervention or maintenance.
Should the system malfunction, the condition of the antenna systems as well as the continuity of the
cabling should be checked before replacing any of the OMU units.
In the unlikely event of a unit failure, the field replaceable components (antenna unit, cables, etc.)
should be checked and replaced if faulty and the system restored.
A failed unit can be removed and replaced with a spare while the rest of the system (other OMUs) is
still in operation.
This product is equipped with Class 3B lasers, as per definition in EN 60825-1.
Caution!!!
Un-terminated optical receptacles may emit laser radiation.
Do not stare into beam or view with optical instruments.
Note! The power supply of the failed OMU should be isolated from AC mains and DC power before
any module is replaced.
