his projection keyboard will work via Bluetooth HID. connection to main devices,

like Tablet PC, Smartphone, Desktop PC and Video game .
As a new input device, using the built-in infrared laser transmitter to project the standard keyboard on the working surface ,
you can locate the click position and input the information by the method of optical identification.
Without physical keyboard, small size, easy to carry, this projection keyboard can adapt to most of the working environment.
The project has microphone at the backside of the keyboard,so cool!!!!!

How This Product Works:
This product emits infrared light from the lower end of the product to detect objects such as fingers. When an object passes through the are illuminated by the infrared light source, any infrared light reflecting off an object is detected by the sensor.
Information on the position and movement of the object is then analyzed to perform the product's role as a keyboard.

Conditions to Avoid:
1. Avoid direct sunlight.
2. Avoid low color temperature light source, such as tungsten, halogen, or incandescent lamp.
3. Avoid uneven or irregular surfaces. Place the product on flat surfaces.
4. Avoid a table or surface that is as transparent or reflective as glass or mirror.
5. Avoid placing any objects within the space between the main unit and the laser projected keyboard layout.

Note:
Because this product uses infrared rays, strong infrared radiation from direct or reflected sunlight or from tungsten
(halogen or incandescent) lighting may cause operating error

Caution:
Although this equipment is classified as Class 2 laser product, for your safety, do not directly expose your eyes to pattern projection beams orinfrared rays.
1. For safety reasons, be sure to use only the microUSB to USB cable specified for this product.
2. Make sure to fully charge the battery before using the product for the first time.
3. Battery charging times may vary slightly depending on the ambient temperature.

5. Using or storing the battery in high temperature, humidity and pressure environments may cause the battery to explode.
6. Since the battery is a consumable item, its storage capacity decreases gradually as time passes.

Connecting via Bluetooth:
Connection via Bluetooth HID does not require installation of separate driver as long as the host device has HID compatibility.
Bluetooth 2.1 or higher required for connecting to some devices
Note:Projection Keyboard will automatically attempt to re-connect to the recently connected devices. If no previous device is found then it will listen for a new connection with any available HID compatible device.
