Quick Guide

1. Plan Profile

Bluetooth is a short distance wireless communication technology which enable mobile phone, notebook, PDA, digital camera, fax

machine, printing machine and all kinds of household electrical appliance to communicate and share the information through wireless internet.

Bluetooth technology caused the wireless wave to take the place of the traditional equipment and the connecting of the network. Bluetooth will provide an environment without wire limitation and could proceed voice and data communication freely.

2. Bluetooth block

Bluetooth block is the major sensor of the plan, it charges to control other side components and communicate with them, such as mouse button, scroll wheel and optical sensor, as well as to handle Bluetooth agreement, communicate with HID Host equipment and below mentioned Bluetooth optical receiver.

Optical Sensor

The sensor of the plan is ADNS-2030, this optical sensor is produced

with low power damage, which combines the optical sensor and control sensor. To analyze and compare the photo, which taken by the optical sensor, then to calculate the movement speed of the mouse.

Scroll Wheel

To judge the scrolling of the scroll wheel through the tube of the red ray, Bluetooth block will operate with the shining tube of the red ray, and to test the power of the relative LED at the same time, then get the scroll status of the scroll wheel after calculating.

Button

Including left, middle, right button and connecting button; Bluetooth will control the four buttons automatically, and do the relative response. When clicking the connecting button, the Bluetooth will source the neighbor Bluetooth, it could be use after monitoring and connecting. Bluetooth will set up connecting automatically once open the machine after firstly connecting.

Power

The working voltage for Bluetooth block could be 2.7-3.3V, could use battery to supply the power. There is a power monitor at the inside of the Bluetooth block, the block can't work, if the working power is out of the efficient range. So please change the battery when the mouse work abnormally or unworkable. This plan with low power damage, 2AA could work 3-6 month.

3. Bluetooth optical mouse receiver (receiver not included)

The receiver has tow working methods : HID Dongle and USB Dongle, they can be exchanged by clicking the button.

HID Dongle is the specialized receiver for Bluetooth optical mouse and Bluetooth keyboard, they don't need fix extra driver, plug then use it, and could support the mouse and keyboard at the same time.

USB Dongle need to fix the relative soft component on the computer, which could realize various Bluetooth functions, such as photo transit, wireless net working, listen the MP3, printing and so on, it also could support the Bluetooth mouse and keyboard at the same time if we apply the newest soft components.

The selection of receiver method of the Bluetooth optical mouse is through one of his switch.

4.Profile Supported Bluetooth Profile

- HID Profile

Supported Bluetooth existing equipments (such as the keyboard, mouse, DJ, game pole and monitor with Bluetooth functions) to send the message to Bluetooth receiver, in order to control the equipment of the Bluetooth receiver (such as PC machine).

Communication

Before the connecting between Bluetooth optical mouse and the receiver, to control the mouse for checking, matching, and connecting the receiver by clicking the button.

After the connecting between Bluetooth optical mouse and the receiver, Bluetooth optical mouse will send the instruction to the receiver by checking the status of optical sensor, scroll wheel and button.

Energy Saving

Because of Bluetooth optical mouse use battery to provide the power, Bluetooth applies one kind of high efficiency energy saving model (with four degree energy saving model). After connecting with the Bluetooth receiver, if data need to be transited between Bluetooth optical mouse and the receiver, Bluetooth optical mouse is in the first degree of energy saving model, if no data need to be transited between Bluetooth optical mouse and the receiver, 20 seconds later, will go into the second degree of energy saving model, 40 seconds later, will go into the third degree of energy saving model, 80 second later, the Bluetooth optical mouse will break the connecting. If Bluetooth optical mouse is not in the first degree of energy saving model, and data is under transiting, the Bluetooth optical mouse will enter first degree of energy saving model automatically.

5. Electrical characteristics:

1.Power Grade Class 2(10M)

Transmit power Range is Class 2(10M) and CLASS1 (100M) Due to the place and other reasons the efficient operating range is 5-6 meter
