BLUETOOTH Technology
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 143) .
❑
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.
❑
High-speed communications between your computer and BLUETOOTH devices are available when they are compliant
with BLUETOOTH Core Specification Version 3.0 + HS. For the high-speed communications, enable both the wireless
LAN and BLUETOOTH functions on the computer.

Some BLUETOOTH profiles do not support high-speed communications.
