Setup Guide
1. Charging the Gimbal
Before first use, fully charge the gimbal. Connect the USB charging cable to the gimbal's charging port and a suitable USB power adapter (not included). The indicator lights will show charging status and turn solid when fully charged. A full charge takes approximately 2.5 hours.
2. Unfolding and Mounting Your Smartphone
- Gently unfold the gimbal from its compact, folded state. Ensure all axes are unlocked and can move freely.
- Mount your smartphone securely into the phone clamp. Ensure the phone is centered and balanced. For optimal performance, remove bulky phone cases if they interfere with balancing or exceed the thickness/weight limits.
- Adjust the phone's position in the clamp to achieve a balanced state. The gimbal should remain level even before powering on.
