Connecting the RF OUT Ports

Follow these steps to connect the RF OUT ports.
CAUTION:
Turning on the MQAM with default RF output level may cause RF
interference with the services of other units connected to the network.
Therefore, set the RF output frequency and RF output level before you
connect any RF OUT ports to the network.
Important! We strongly recommend that you configure and adjust
frequencies from the Set Up GQAM window on the DNCS. See
Provisioning the MQAM on the DNCS (on page 38) for detailed
instructions.
