Using Usb And Bluetooth At The Same Time - Handy Tech Basic Braille User Manual

Basic Braille
Installation
Please connect the micro USB plug to the micro USB port on the right side of your Basic
Braille. The flat plug is then plugged into the PC's USB port.
If the Basic Braille is to be used as a medical device, the PC must conform to all Medical
Device Standards, or else it must have a ground connection or be connected to an
isolating transformer. Even if you are not using the Basic Braille as a medical device, we
recommend connecting it only to a grounded PC. Otherwise you might feel the voltage on
the housing, which is harmless and permitted for non-medical devices but unpleasant.
When the PC is turned on, the Basic Braille will automatically be recognized by USB-
enabled operating systems. If recognized by the PC, the USB connection becomes
primary. If the Bluetooth interface is active, it might be the primary channel. In this case
please press dot [2] and [5] together for approx. one second, to switch to the USB channel.
The power for the Basic Braille is supplied via the USB interface. The Basic Braille without
Bluetooth interface will turn on automatically as soon as the USB cable is connected and
the PC is turned on.
You can turn on the Basic Braille by a short press on [4] and turn it off by pressing [4] for 5
seconds. The Basic Braille with Bluetooth can be switched off by pressing [4] for 2
seconds, if no connection to any device is established.
Note: If using the Basic Braille with Windows 8, 8.1 or 10, a screen reader must be active.
If there is no screen reader running, Windows will disconnect the Basic Braille when
pressing any Braille key. In order to use the Basic Braille again, you must switch it off and
on.

Using USB and Bluetooth at the same time

From firmware version 3, you can use an USB and Bluetooth connection at the same time.
If you have connected the Basic Braille for example via USB to your PC or laptop, you can
hook on parallel a smart phone or a second PC via Bluetooth.
To switch between these two connections, press dot [2] and [5] together for 1 second.
Please note, that the Bluetooth setting in Config Mode must be "ON" or "AUTO".
If you choose "AUTO", the Bluetooth channel will be active for 15 minutes after switching
on the Basic Braille. If no connection will be established in this time, the Bluetooth
interface will be deactivated in order to save battery live.
After switching the interface channel, the Basic Braille shows the following messages:
 Disconnected: no connection, switching not possible
 Bluetooth only / USB Only: only one connection, switching not possible
 USB Bluetooth: the USB connection becomes primary
 Bluetooth USB: the Bluetooth connection becomes primary
Note: While switching between USB and Bluetooth it might happen, that the screen reader
is sending data to the Basic Braille and you cannot see this message because it appears
very shortly.
