INSTALLATION

Placing of 75 Ω charges
Check that the unused F-connector inputs and outputs are charged with an RS-275 (code 9120011) charge
of 75 Ω.

Installation of external LNB units

It is extremely important to point the satellite dish correctly, since the quality of digital signals is greatly dimi-
nished when the dish is incorrectly pointed (although analogical signals may be acceptable).
Adjust the skew of the external LNB unit to obtain the minimum cross-polarisation possible. Correct adjus-
tment is crucial for good quality digital signal reception.
