- A camera should ALWAYS be attached to the S1 whenever it is powered on.
- Firmware upgrade will take 60~80 seconds to be completed after pressing ‘Firmware Upgrade’ button. IF the S1 stays asleep after 80 seconds, firmware upgrade has possibly been failed. In this case, please try again after reconnecting the S1 to the PC
- As both calibration and firmware update software use virtual COM port to connect to your Gimbal, you may need to download a device driver. When you connect your gimbal to a PC via USB cable and turn it on, please check on the device manager of your Windows to see if there is CP210x USB to UART Bridge existing. If not, you need to download the driver from http://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
