3.14 RF Output Interfaces
Opening RF lines during operation may cause electric arcs that can
cause burns and eye injuries. RF output ports 1 and 2 must be
terminated into a broadcast antenna or test load.
The DRU-2KW includes two (2) RF output ports, which are located on the OFN cabinet top
panel.
During the installation procedure, these outputs must be terminated into a broadcast
antenna or test load.
