The Bluetooth devices must recognize each other in order to be connectable for use.
In certain devices, simply turning on the power will not produce a connectable state. Moreover,
the energy-saving feature may come into effect after a certain amount of time, which will
prevent the devices from being detected. Please refer to the specific product instruction manual
for further details.
Microwave ovens, wireless LANs and other radio wave-emitting devices located nearby may
affect Bluetooth communication.
Please ensure that your devices have been accordingly situated, and that the above devices are
not in use when you are operating your Bluetooth device.
Bluetooth cannot be used if the devices have not been turned on.
Some PCs and other components have a Bluetooth communication switch that operates
independently of the main power. Bluetooth cannot function if this switch has been turned off.

an intended function can be properly utilized when you use a Bluetooth device.
Examples of Bluetooth devices include mice and keyboards (input devices), printers (output
devices) and wireless modems (communication devices). Functions that can be utilized by such
devices are called "services."
In order for these services to be used reliably, Bluetooth devices are provided with common
specifications known as "profiles."
For example, when a PC makes a connection to a Bluetooth device, it obtains the profile of the
corresponding device and thereby ascertains which functions (services) the device offers.
As an example, imagine someone who travels overseas.
The traveller is only able to converse properly with their counterpart if both speak a language
(English, Japanese, Chinese, etc.) they both understand.
