How this exact system works
Remove RF, lower the pair, compare and inspect both legs, label the band clearly, roll the coax, and keep each matched pair together.
The boundary that prevents mistakes
Never mix legs from different pairs or call WARC-D LINK-D. Current privileges, band plans, propagation, and site rules remain operator responsibilities.
Use this field sequence
Quarantine damaged parts, label settings and matched components, update the kit inventory and field record, and do not return the system to service until the exact fault is corrected.
