BLUETOOTH Technology

What should I do if other BLUETOOTH devices cannot find my computer?

❑Make sure both devices have the BLUETOOTH function enabled.

❑Make sure the WIRELESS indicator light is lit on your computer.

❑Your computer and the device may be too far apart. Wireless BLUETOOTH technology works best when the devices are

within 10 meters of each other.

What should I do if I cannot find the BLUETOOTH device I want to communicate with?

❑Check that the BLUETOOTH function of the device you want to communicate with is on. See the other device's manual

for more information.

❑If the device you want to communicate with is already communicating with another BLUETOOTH device, it may not be

found or it may not be able to communicate with your computer.

❑To allow other BLUETOOTH devices to communicate with your computer, follow these steps:

1Click Start and Devices and Printers.

2Right-click the BLUETOOTH device icon and click Bluetooth settings.

3Click the Options tab and select the Allow Bluetooth devices to find this computer check box.
