Cautions! 

The receiver provides DC power (refer to Chapter 3, Operating the Equipment 
Locally) via the active L-band input connector to drive an LNB (Low Noise Block 
Down-Converter). Do not connect equipment other than an LNB to this connector. 
Failure to do this may result in damage to the external equipment. 

The F-type Connector is not suitable for repeated connection and disconnection. 
When intended for use in this way, fit a sacrificial connector and connect to it. 

Connect the IF Monitor input to a suitable IF frequency source e.g. a 
satellite modulator. The input can be activated using Input Status 
Menu (Menu 2). 

This monitor input is designed to give error-free demodulation in the 
presence of a wanted carrier only, for example when being fed 
directly from a satellite modulator. 

The specification for this connector is given in Annex B, Technical Specification.
