Maintaining the Performance of the R450 System
The first major activity is to be sure that you have properly installed
all the R450 MIUs so that the R450 System can reliably receive their
transmissions.
The troubleshooting section of this guide includes recommendations
on how to verify that the R450 DC and antenna system are performing
up to specification.
Storm activity can degrade the performance of the R450 DCs. If this
happens, the lightning arrestors should be checked and replaced if
defective. Inspect the small ceramic disk located inside the arrestor
under the 9/16 inch cap. A new disk is white with silver ends. If there
are black traces or the disk is totally black, it should be replaced. If
the disk shows severe damage, the entire arrestor should be replaced.
Running the surveys again using the radio receiver can identify new
sources of interference. Problems related to specific time windows
should have the surveys performed during those time periods.
