Exchange standard of a regular change parts
In this radar there are parts that recommend a regular exchange. Before the parts are increasingly consumed and
don't work, the exchange is recommended.
A standard exchange interval of each part is as follows.
Remark ) 1. The life of parts changes by the using system environment.
2. The following standard exchange interval is not guaranteed value.
