5 Maintenance
5.1 General
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.
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.
5.2 Preventive Maintenance
The OMU does not require any preventative maintenance apart from changing the battery every three years.
Caution
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to local laws and instructions.
5.3 Product Disposal
Disposal of this product must be handled according to all national laws and regulations.
