1. Dashboard and Windshield Mounting (Suction Cup)
- Clean the Surface: Ensure the dashboard or windshield surface is clean and dry.
- Attach Suction Cup: Place the suction cup mount firmly onto the desired flat surface.
- Press and Lock: Press down on the suction cup and then push the locking lever down to create a strong vacuum seal.
- Secure Adhesion (Dashboard): For dashboard mounting, it is recommended to allow the suction cup to adhere for at least 24 hours before attaching the phone holder and using it, especially in varying temperatures, to ensure maximum stability.

2. Air Vent Mounting
- Attach Vent Clip: Connect the air vent clip attachment to the back of the phone holder unit.
- Hook onto Vent: Insert the metal hook of the vent clip into a suitable air vent blade.
- Secure the Clip: Push the clip firmly to ensure it clamps tightly onto the vent blade. Tighten any adjustment nuts on the clip to prevent movement.

Maintenance
- Regularly clean the suction cup and mounting surface to ensure strong adhesion. Use warm water to rinse the gel pad if it loses stickiness, then air dry.
- Wipe the phone holder unit with a soft, damp cloth to remove dust and grime. Avoid harsh chemicals.
- Ensure all adjustable parts are free of debris to maintain smooth operation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Suction cup keeps falling off. | Surface not clean, suction cup dirty, extreme temperatures, insufficient curing time. | Clean surface and suction cup thoroughly. Rinse gel pad with water and air dry. For dashboard, allow 24 hours for adhesion to cure. In hot weather, consider using the air vent mount. |
| Phone holder is too bouncy when extended. | Arm fully extended without support. | Adjust the arm so the holder slightly rests on the dashboard for added stability. |
| Cannot rotate the phone holder. | Adjustment nut behind the holder is too tight. | Loosen the adjustment nut slightly to allow rotation, then re-tighten to secure. |
| Phone is difficult to remove. | Release button not pressed correctly or located inconveniently. | Ensure the release button on the bottom-back of the holder is fully pressed to open the arms. |
