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.
4. The battery may not be charged to 100 percent of its rated cell capacity even when the charging indicate LED goes out.
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.

Identifying Parts and Their Functions:
1. Projector: Uses a red laser to project the image of a keyboard onto a flat surface in front of the typist.
2. Sensor: Picks up the infrared light reflected off the typist’s fingers and triangulates the location of the reflected light to determine which key was pressed. This sensor provides a keyboard function.
3. IR Light: Uses an infrared laser to emit an invisible plane of light a few millimeters above the projection surface so that the infrared light can be reflected off of the typist’s fingers to the sensor.

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.
