Introduction
Thank you for choosing the TOPK 2-IN-1 Car Phone Holder. This manual provides essential information for the safe and effective use of your new car phone holder. This versatile holder is designed to provide secure mounting for your smartphone on both your car's dashboard and air vent, featuring gravity expansion for ease of use and multi-angle adjustability. It is compatible with most smartphones ranging from 4 to 7 inches.

Setup Instructions
Your TOPK 2-IN-1 Car Phone Holder offers two primary mounting methods: a suction cup for dashboard use and a clip for air vent installation.
1. Dashboard Suction Cup Mount
- Choose a Location: Select a flat, clean, and smooth area on your car's dashboard. Ensure the chosen spot does not obstruct your view of the road or interfere with airbags.
- Clean the Surface: Thoroughly clean the dashboard surface where the suction cup will be placed. Dust and oils can reduce adhesion.
- Attach the Suction Cup: Press the suction cup firmly onto the cleaned dashboard surface.
- Engage the Lock: Push down the mechanical pressure valve (lever) on the suction cup base to create a strong vacuum seal.
- Adjust the Arm: Loosen the adjustment knob on the arm to position the phone holder at your desired height and angle. Tighten the knob once adjusted.
Important Safety Note: The suction cup mount is designed exclusively for dashboard use. It is NOT suitable for windshield mounting, as this may obstruct your view and is not as stable.

2. Air Vent Mount (if applicable to your model)
If your package includes an air vent clip attachment:
- Attach the Clip: Securely attach the air vent clip to the back of the phone holder unit.
- Insert into Air Vent: Carefully slide the air vent clip onto one of your car's air vent blades. Ensure it is firmly seated.
- Adjust Angle: Use the ball joint on the back of the holder to adjust the viewing angle.
Operating Instructions
Inserting and Removing Your Phone
- To Insert: Gently place your phone into the holder. The gravity expansion mechanism will automatically clamp the phone securely. If your phone is large, adjust the retractable bottom foot of the holder before inserting to ensure a snug fit.
- To Remove: With one hand, simply lift your phone upwards. The side clamps will automatically release, allowing for quick and easy removal.

Adjusting Viewing Angle
The TOPK Car Phone Holder offers extensive adjustability for optimal viewing:
- Arm Rotation: The main arm can be rotated up to 260 degrees, allowing you to position the holder closer or further away from you.
- Ball Joint Rotation: The phone cradle is attached via a 360-degree rotatable ball joint, enabling seamless switching between portrait and landscape orientations.
- Total Free Rotation: Combined, these features provide a total of 540 degrees of free rotation, ensuring you can achieve the best viewing angle for navigation or calls.


Maintenance
To ensure the longevity and optimal performance of your TOPK Car Phone Holder, follow these simple maintenance tips:
- Cleaning the Suction Cup: If the suction cup's stickiness diminishes over time, simply rinse it with warm water and let it air dry. The nano-silica material will regain its strong adhesive properties.
- General Cleaning: Wipe the holder with a soft, damp cloth to remove dust and grime. Avoid using harsh chemicals or abrasive cleaners, as these can damage the carbon fiber texture and silicone pads.
- Check Connections: Periodically check that all adjustable joints and the suction cup lever are securely tightened to prevent wobbling during driving.
Troubleshooting
- Holder is not sticking to the dashboard:
- Ensure the dashboard surface is clean, dry, and free of dust or oils.
- Rinse the suction cup with water and let it air dry to restore stickiness.
- Verify that the mechanical pressure valve is fully engaged after pressing the suction cup onto the surface.
- Ensure the surface is flat and smooth; textured or curved surfaces may not provide adequate adhesion.
- Phone is not held securely or falls out:
- Check that your phone's screen diagonal (4-7 inches) and physical width (2.55-4.2 inches) are within the holder's compatibility range.
- Adjust the retractable bottom foot of the holder to properly support larger or heavier phones.
- Ensure the gravity expansion clamps are fully engaged around your phone.
- Holder wobbles or shifts during driving:
- Re-secure the suction cup to the dashboard, ensuring a strong seal.
- Tighten all adjustment knobs and ball joint connections firmly.
- For air vent mounts, ensure the clip is securely attached to a stable vent blade.
