Operating Instructions
- Placing Your Phone: Gently slide your phone downwards into the holder. The gravity-activated arms will automatically clamp onto your phone, securing it in place.
- Removing Your Phone: Lift your phone upwards. The gravity arms will release, allowing you to easily remove your device.
- Adjusting Viewing Angle: Loosen the knob on the ball joint to adjust the phone's angle (vertical or horizontal) and rotation (360 degrees). Tighten the knob to secure the desired position.
Maintenance
- Regularly check that the vent hook is securely tightened to prevent wobbling.
- Clean the silicone pads with a soft, damp cloth to maintain optimal grip and prevent scratches.
- Avoid exposing the mount to extreme temperatures for prolonged periods.
Troubleshooting
- Mount feels loose: Ensure the vent hook knob is fully tightened. Verify that your car's vent type is compatible (not circular).
- Phone is not clamping securely: Check that your phone's thickness (with case) does not exceed 0.55 inches. Ensure the phone is placed correctly to activate the gravity arms.
- Phone holder blocks airflow: The design is intended to minimize airflow blockage. Adjust the mount's position on the vent or the vent's direction if necessary.
