The Vuzix M400 is a powerful and smart wearable that combines the convenience of a digital assistant with the power of an augmented reality device. With its slim design, the Vuzix M400 fits comfortably and securely on your head, enabling you to access digital features, hands-free.
One of its key features is the dual HD display that superimposes transparent digital information onto a physical space. This information can be from your calendar, emails, or notifications, and can be presented in 3D augmented reality for a more immersive experience. Additionally, the Vuzix M400 is equipped with a camera and microphone that allow you to take photos and record audio, making it a truly powerful and enhanced device.
Your M400 Smart Glasses System is an ergonomically designed, wearable Android-based computer with Wi-Fi connectivity, voice-command functionality and HD camera — right out of the box, including:
• M400 viewer with an adjustable display screen
• USB-A Battery
• USB-A to USB-C power cable
• USB-A to Micro USB cable (for charging the USB-A Battery)
• M-Series Lens-less frames
• Soft case for storage
CHARGING FOR FIRST-TIME USE
Charge the battery before use with a wall charger, and wait until all three LEDs are solid. Can take up to two hours if the battery is fully empty
ASSEMBLING YOUR M400 SMART GLASSES SYSTEM
1. The viewer will be worn on the dominant eye. Before attaching the viewer to either side of the Smart Glasses frames, determine your dominant eye for optimum use of M400 capabilities.
2. Attach the viewer to the side of the frame by sliding the mounting rail onto the temple mount on the frames. Once properly fitted, the unit will be adjustable by sliding forward and backward.
3. Using the same mounting process, attach the USB-A battery to the other side of the frames.
4. Plug the USB-C end of the connector cable into the viewer and the USB-A connector to the USB-A battery. Press the power button on the battery for 2 seconds to turn on the system. The LED on the battery will illuminate when the system is powered on.
5. When ready to wear your M400 Smart Glasses, lift the power cable over your head to rest on your shoulders as you place the Smart Glasses as you would a pair of glasses.
6. Ear hooks and alternate nose pads are available for proper fit.
How to determine your dominant eye: Extend your hands, placing them together to make a small triangle between your thumbs and knuckle. Keeping both eyes open, center a nearby object inside the triangle. Close each eye one at a time. Notice how the object moves out of view when one eye is closed? When the object remains in view, the open eye is your dominant eye.
WEARING THE M400
1. Make sure the Smart Glasses frames are resting comfortably on your head. Frames can be worn over the top of a majority of regular prescription eyewear. The nosepiece of the frames can be adjusted to fit comfortably and securely.
2. After mounting the viewer, adjust the viewer as shown until it is a comfortable distance and preferred position from your dominant eye.
3. Adjust the eyepiece as shown until you can see the full image.
4. Additional mounting options, including frames with prescription lenses, safety frames, hard hat, headband mounts, and more, can be found online at Vuzix.com under Products > M400 Smart Glasses > Accessories
FOCUSING NEAR-FIELD: First time users may find some challenges focusing their near-field
vision on the M400 display. Make sure to keep both eyes open, some users may need up to 20 minutes to adjust.

DEVELOPING FOR M400
Developer documentation is available at vuzix.com/developers. In order to power the unit during development, please note:
• The included battery does not support data pass-through.
• The viewer should be plugged into the developer’s machine with a USB C-to-C cable for the best experience.
• If a USB A-to-C cable must be used, then using a CDP-capable port will provide enough power. If the USB-A port is not providing sufficient power, functions of the device may become impaired without notice, and the viewer may shut down completely.
