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 switch is on and the WIRELESS indicator light is lit on your computer.

❑ You cannot use the BLUETOOTH function while your computer is in a power saving mode. Bring the computer back to

Normal mode, then turn on the WIRELESS switch.

❑ 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:

1 Click Start and Devices and Printers.

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

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

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

❑ Check the suggestions in What should I do if I cannot find the BLUETOOTH device I want to communicate with?

(page 119)

.

❑ Make sure the other devices are authenticated.

❑ The data transfer distance can be shorter than 10 meters depending on existing obstacles between the two devices, on radio wave quality, and on the operating system or the software in use. Move your computer and BLUETOOTH devices closer to each other.

Why is my BLUETOOTH connection slow?

❑ The data transfer speed depends on the obstructions and/or the distance between the two devices, on the radio wave quality, and on the operating system or the software in use. Move your computer and BLUETOOTH devices closer to each other.

❑ The 2.4 GHz band, with which BLUETOOTH devices or wireless LAN devices work, is used by various devices. Although

BLUETOOTH devices use the technology to minimize radio interference from other devices that use the same band, such radio interference may cause slower communication speeds and shorter distances or communication failures.

❑ If a version of a BLUETOOTH standard employed on the BLUETOOTH device with which you want to communicate is not the same version as the one employed on your computer, the communication speed becomes slower.

Can I use a device with BLUETOOTH technology on airplanes?

With BLUETOOTH technology, your computer transmits a radio frequency of 2.4 GHz. Sensitive locations, such as hospitals and airplanes, may have restrictions on use of BLUETOOTH devices to avoid radio interference. Check with facility staff to see if use of the BLUETOOTH function on the computer is permitted.
