Siemens OPENSTAGE 60 ユーザーズマニュアル

Bluetooth is an open standard for high-performance 
technology and allows wireless communication be-
tween PCs, PDAs, and mobile telephones. 

In contrast to infrared connections, Bluetooth does not 
require a visual contact for communication purposes 
and can be used over distances of up to 10 meters.

To exchange data between Bluetooth-enabled devices, 
the devices need to undergo a once-off discovery pro-
cedure.

When first enabling a connection to a Bluetooth device, 
this function must be switched on 

The OpenStage is discoverable for other Bluetooth de-
vices by default.

To prevent unauthorized access, we recommend deac-
tivating discoverability once you have enabled the con-
nection to a new Bluetooth device.

Pairing is the process used by two Bluetooth-enabled 
devices to "see" one another and to "recognize" that they 
can exchange data. It is therefore used for checking the 
access authorization of a Bluetooth device in a Blue-
tooth network. To do this, a 128 Bit pairing key is creat-
ed for subsequent identification.

A connection is established for devices that are 
already connected even if the "Discoverable" 
function is deactivated.

Pairing is only performed the first time contact is 
established between a Bluetooth device and 
your OpenStage. If the Bluetooth device is suc-
cessfully paired, no further access authorization 
checks are necessary. Instead, each subsequent 
check uses the previously created connection 
key.
