If the device is a new Bluetooth device, make sure that the charge before making connections or open. Especially the Bluetooth headset, must be charged before use

Device is turned on

Open the paired devices need power. For some devices, such as Bluetooth wireless headsets, the device is turned while the pairing process starts.

Open the Bluetooth function

When you receive the device, Bluetooth functionality of the device may have been turned on, it may not open. For most computer users need to turn on Bluetooth radio functions from the control panel or system preferences.

The device is set to visible

As a security measure, some devices can be set to turn off the Bluetooth function, hidden or visible. When you try to connect the device, the user should set the device to be seen, so as to have found each other. Upon completion of device pairing, if users fear the device will be discovered other devices, you can set the device to hide.

The two devices to connect mode

After two devices are fully charged, turn on the device and turn Bluetooth functionality, each device needs to initialize communication session.
Typically, when the connection between the two devices, one device as the "host" and the other device is as "visitors." The host device is a device with a user interface, since the majority of the connection settings will be. A host device can be another device, or other devices can be used as guest. For example, when the phone is paired with the headset, the phone is the host. However, when the phone is paired with a laptop computer, a laptop computer is the host.

Enter the password

Each other after the device was found, the user will be asked to enter a password in one or two devices. In some cases, such as when connected to a wireless headset, the password is fixed by the manufacturer of the headphone specified password. At this point, the user needs to enter the password for this specified in the host device. Users can find the password in the user manual. In other cases, the user can enter his / her own password. In these cases, the user will enter the password each time in both devices. Strongly recommends that users set for a pairing process 8 alphanumeric characters password.

Described above is a Bluetooth wireless keyboard and infrared wireless keyboard, 2.4G wireless keyboard and mouse now has the latest technology and what is 2.4G, it is actually a wireless transmission technology, 2.4G is to represent a data transfer rate, the market is now 2.4G wireless keyboard and mouse that has a USB receiver, a mini type, generally plug in the computer, you can directly use.

Now many manufacturers of wireless keyboard and mouse, there will always unstable performance, this is the case, mainly manufacturers in order to save costs, the use of cheap chips.

7: Precautions

1, charging: charge any brand of Bluetooth devices are three hours maximum time limit. Usually see lights on the keyboard can be discolored or close off the. For a long time to charge the product will inflicting serious injury.

2, if a long time without a wireless keyboard, it's best to be charged once a month or so to the device. So that its built-in battery can not be charged to enter a period of dormancy and used again.

3, the current case is still supported by the vast majority of computer wireless keyboard into BIOS, because the computer into the operating system before the driver is not loaded, so I can not change the BIOS settings with a wireless keyboard. Some people say that my wireless keyboard is free driver Yeah, plug can be used, or why not enter the BIOS it?
