How to connect the cables for X-band radar (TR-DOWN)
Some parts or wiring have been omitted from the illustrations for clarity. Also, in the
procedure, mainly figures of magnetron radar are shown.
1. Loosen four bolts from the rear cover to remove the rear cover. If the de-icer is
already installed, loosen two bolts inside the antenna to remove the front cover.
Note 1:
The cable for the performance monitor is connected between the rear
cover and the RF-TB Board in the Antenna Unit. Open the cover slowly to prevent
damage to the cable and connector.
Note 2:
If the de-icer is to be installed, remove four M5 screws and spread open
the right and left heater elements on the cover, then remove the front cover, being
careful not to hit the elements on the radiator or chassis.
2. Disconnect the performance monitor connector (J807) from the RF-TB Board.
