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.
