2.6 Switching Between Connected Bluetooth Devices

Switching between connected devices on VarioUltra is achieved in
Braille Display Mode. Press and hold S2, tap and release the
appropriate braille key, and then release S2.
To switch between USB and the four channels of Bluetooth (BT), do the
following:
_ USB: S2 + B1
_ BT1: S2 + B4
_ BT2: S2 + B5
_ BT3: S2 + B6
_ BT4: S2 + B8
When switching to the USB channel, the braille display will show USB.
When switching to one of the Bluetooth channels, the braille display will
show something like, "BT1 My iPhone", or whatever name your device is
recognized as. If you see brackets either side of the device name, it
means the device is paired, but not in range.
If Bluetooth was off before attempting to connect with a previously paired
device, selecting the device will force Bluetooth to switch on
automatically. When this happens a message on the braille display will
ask you to wait while Bluetooth is switched on, and then it will display the
Bluetooth channel and device name information. It only takes a second
or two.
