{% hint style="warning" %}
This sub-protocol is known to be problematic.  This is due to the emulation of the original radio's RF component.
{% endhint %}

If the model does not respond well to inputs, or is hard to bind, you can try to switch the emulation mode by using an option value (RF Freq. tuning) other than 0.

Once the value is not set to 0 it is used for frequency fine tuning.  See the [Frequency Tuning page](https://www.multi-module.org/using-the-module/frequency-tuning) for more details.
