Active RSM / Internal Mic If No Bluetooth Mic

Radio Wide

Bluetooth

Enables the microphone (mic) audio source to come from a Bluetooth (BT) Wireless Headset, a Remote Speaker Mic (RSM), a Vehicular Adapter (VA) connected mic, or an internal mic when attempting to key up the radio with either the Bluetooth Headset PTT button-press or pressing the PTT button on the BT Wireless Headset.

When disabled, if the radio-user initiates a Bluetooth Headset PTT button-press or presses the PTT button on the BT Wireless Headset, the radio will only key up if the BT Wireless Headset is connected, and use the Wireless Headset's mic as the active mic audio source.
