### **Q 2:** What application/software do Gremsy gimbals use?

* Gremsy developed gTune app & software to configure gimbals.

### **Q 3:** What are general good practices while using the gTune?

* Before running gTune mobile app, make sure to connect with the gimbal’s Bluetooth. Otherwise, the app can’t connect to the gimbal properly.
* Firmware upgrading procedure with gTune Desktop software: Before upgrading, please temporarily unplug the receiver (if available). Otherwise, you will be stuck on erasing step and can not get it completed. Of course, the software will remind you but it’s better to do it yourself first.

### **Q 4:** How can I save profiles?
