Setup and Installation
Surface Preparation
Before installing the suction cup mount, ensure the chosen surface (dashboard or windshield) is clean and dry. Dust and stains can affect adhesion.
- Use the provided wet wipe to clean the desired flat surface.
- Follow with the dry wipe to remove any moisture and ensure the surface is completely dry.
Dashboard/Windshield Mount Installation
Follow these steps for secure attachment of the suction cup mount:
- Clean the central control panel or windshield thoroughly.
- Press the suction cup firmly onto the cleaned surface for 10 seconds.
- While maintaining pressure, rotate the bottom of the suction cup clockwise from the "UNLOCK" icon to the "LOCK" icon. Ensure it is fully rotated to the "LOCK" position for optimal performance.
- Allow the suction cup to adhere for 15 minutes before attaching your phone for higher adhesion.

Air Vent Mount Installation (Optional)
If using the air vent mount, attach the phone holder to the air vent clip mount. The clip is designed to securely fasten to most horizontal or vertical air vent fins.
- Unscrew the nut from the back of the phone holder.
- Place the nut onto the ball joint of the air vent clip mount.
- Push the ball joint into the socket on the back of the phone holder.
- Tighten the nut to secure the phone holder to the air vent clip mount.
- Attach the air vent clip to a suitable air vent fin in your vehicle.
Attaching the Phone Holder to the Mount
Once your chosen mount (suction cup or air vent) is securely installed, attach the phone holder unit:
- Ensure the large screw nut is placed over the ball joint of the mount arm.
- Push the ball joint firmly into the circular socket on the back of the phone holder until it clicks into place.
- Tighten the large screw nut clockwise to secure the phone holder at the desired angle.
Operating Instructions
Securing Your Phone
The phone holder features adjustable clamps to accommodate various phone sizes:
- Press the release button (usually on the side or back) to open the side clamps.
- Place your smartphone into the holder, ensuring it rests on the bottom support.
- Gently squeeze the side clamps inward until they firmly grip your phone. The holder is suitable for phones between 4.0"-7.0".
Adjusting Viewing Angle
The mount offers flexibility for optimal viewing:
- The 360° ball joint allows you to rotate your phone to portrait or landscape orientation.
- The mechanical arm can be adjusted up to 270° and extended from 5" to 7.2" to bring your phone closer or further away.
- Loosen the adjustment knobs on the arm to change its position, then tighten them to lock the desired angle.
Maintenance
Cleaning the Suction Cup
To restore the stickiness of the suction cup after prolonged use or if it gets smudged, follow these steps:
- Rinse the bottom of the suction cup with warm water.
- Allow the pad to air dry completely. Do not wipe with a cloth.
- Once dry, the stickiness should be restored.

Troubleshooting
- Suction Cup Not Sticking: Ensure the surface is clean, dry, and flat. Leather dashboards are not suitable for all suction cups; use on the windshield instead. Make sure the rotate-lock mechanism is fully engaged to the "LOCK" position. Clean the suction cup as per maintenance instructions.
- Phone Holder Feels Loose: Verify that all nuts and adjustment points are tightened securely. Ensure the ball joint is fully inserted into its socket.
- Phone Not Fitting: Adjust the side clamps by pressing the release button and manually expanding them to fit your phone. The holder supports phones from 4.0" to 7.0".
