3.12.2 Loopback Test Signal Selection
The Lynx radio allows loopback operation using an internally generated test signal or using an
externally generated test signal. A single DIP switch segment allows the operator to select the use
of either the internal or an external test signal. The factory setting for loopback mode is internal. On
1xE1, 2xE1, and 4xE1 models, SW1 position 3 and on the 8xE1 model, SW-3 position 1 will select
the loopback test source.
