CAUTION

After removing the protective covers, ensure that no foreign

material or moisture enters the antenna waveguide or TRF.

2. Install the appropriate o-ring on the LNB or TRF, as follows:

a. If only one of the mating flanges is grooved, the thin o-ring should be

installed.

b. If both of the mating flanges are grooved, the thick o-ring should be installed.

3. Position the LNB (with o-ring) in place on the antenna OMT and install with

provided M4x12 socket screws and No. 8 SAE washers (split and flat).
