Guaranteed term
The guaranteed term is for one year from after the receipt of the product to the customer, but against the
magnetron refers to below.
Part name
Magnetron
Magnetron guarantee condition :
Only for the radar has sensitivity remarkable decrease, another case is without guaranteed term.
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.

The radar performance decreases though the parts can work even if the following parts pass the exchange
standard interval.
