If possible, install the device in a high location or protect it with appropriate frames or enclosures.

Product Overview
The IWP BT-3400 is a 3D Hologram Fan designed for advertising and display purposes. It utilizes 224 professional HD LED beads to project vivid, borderless 3D images and videos, creating a compelling visual effect of content floating in the air.


Setup Instructions
1. Unpacking and Inspection
Carefully unpack all components and ensure the following items are present:
- Device Host
- Fan Blades (2 for old version, pre-assembled for upgrade version)
- Small Screws (for old version assembly)
- Screwdriver
- TF Card Reader
- Power Adapter (US Plug)
- EU Plug Conversion Adapter
Inspect all components for any signs of damage. If any parts are missing or damaged, please contact customer support.
2. Assembly (Old Version Only)
If you have the 'Old Version' of the 3D Hologram Fan, follow these steps to assemble the fan blades:
- Locate the Device Host and the two Fan Blades.
- Align each fan blade with the slots on the Device Host. Ensure the side with the LED beads is facing upwards.
- Securely fix each blade to the Device Host using the provided small screws and screwdriver. Ensure the screws are tightened firmly to prevent vibration during operation.
