5. Domo Device Controller Operation
5.1 Introduction
To get the most from your radio system you must customise the programming for your operations and area.
The SOLO7 Transmitter uses the Domo Device Controller software running on your PC which enables you to
perform many configuration tasks quickly and easily. These next topics tell you how to connect your PC to
the Nano Transmitter and then use your Domo Device Controller to configure the unit.
If the Device Controller menu shows a ‘lock’ symbol next to a feature, this means that it is not
available for your device variant or that it is missing a license.
5.2 Unit Status Panel
