DO NOT touch the filter in the waveguide output.
The filter is used for Receive band noise and spurious rejection.
If the filter is damaged or dirty, it may not reject a sufficient
value of false receive band.
Connect the IF cable to the input connector of both N and F-
type with 0.68 to 1.13 N・m torque.
Opening or removing any component (e.g. label, and screws)
or sealed area will immediately void the warranty.
