When using the TYTO-01 with radios that have a really high pre-out voltage or a
really low pre-out voltage, some adjustments may be needed.
To do these follow these steps:

2. With the radio at a moderate volume, use a small screwdriver and turn the
potentiometer clockwise to raise the input signal or counterclockwise to lower
the input signal.
