Select Operating Mode
The SB2025 can operate in a number of different modes. The primary alternatives are full duplex,
which is the default mode, repeater and simplex. Using MxTools, the operating mode is
programmed for each channel. When a channel is selected in operation, the SB2025 adopts the
mode programmed for that channel.

The operating mode programmed in the software can be modified by the settings of DIP Switch 2.
