Does this allow connection to Bluetooth headphones or just the headset?
Mobile Phone Connect Options
The bluetooth headset can be connected to mobile phone at the same time while connected to two-way radio. If you have a
phone call during talking on two-way radio, the headset will warn accordingly. Then you may just press the PTT/multi button to answer. After phone call, you may just press the multi button again to hang off and return to radio standby mode. Please follow below instructions to achieve this function:
1. Turn off the adapter and bluetooth headset.
2. Turn on bluetooth of your mobile phone and search for bluetooth device. Then press multi button of bluetooth headset for 3-5 seconds until LED flash red and blue in turn. Your mobile phone will display KBL-001 when the headset searched. When LED flash from red and yellow light to blue light, the headset connected.
3. Turn on the adapter, now you can use the bluetooth headset on both two-way radio and mobile phone.
Edit: To answer your question, it’s not clear based on the above, but it looks like the headset and PTT module work together.
