Remove the grille from the enclosure.
Reverse the above steps when placing the grille back to the
enclosure. The grille should be placed back in the same orientation
before it was removed.
HF waveguide/HF driver unit installed in XY-81 and XY-101 are the
same, so almost the same procedures should be taken to replace
them.

Lift the waveguide up and remove the cables from the HF drive unit.

Spanner.
