Easy Braille
Installation
Page 7
If the Easy 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.
When both the Easy Braille and the PC are turned on, the Easy Braille will
automatically be recognized by USB-enabled operating systems.
The power for the Easy Braille is supplied via the USB interface. You can turn on the
Easy Braille with its power switch as soon as the USB cable is connected and the PC
is turned on.
2.4 Connecting the External Power Supply Unit
If your Easy Braille is equipped with the wireless Bluetooth option, you can charge
the batteries from the mains supply with the aid of the enclosed external power
supply unit. You can continue using your Easy Braille while the batteries are being
charged.
To connect the external power supply unit, insert the round plug on the end of the
cable into the socket in front of the USB socket on the left side of the device. The
plug snaps into place. Then plug the power supply unit into any available mains
outlet socket.
WARNING:
If you are using dry batteries instead of rechargeable batteries in your Easy Braille,
these must always be removed before connecting the external power supply unit,
since the integrated charging controller cannot detect that dry batteries are installed
and would attempt to charge them. This could cause the dry batteries to explode,
causing damage to your Easy Braille and possibly endangering your health.
2.5 Installing the Bluetooth Connection
If your Easy Braille is equipped with a Bluetooth interface, you can establish a
wireless connection between it and a computer or a mobile telephone which also has
a Bluetooth interface. The Bluetooth interface of your Easy Braille is activated
automatically if the device is not connected to an active computer via a USB cable.
The maximum range of such a wireless connection is about 10 metres.
If your PC does not have a Bluetooth interface, you must plug the enclosed Bluetooth
adapter into one of its USB ports.
2.5.1 Bluetooth Connection to a PC
If Windows XP with Service Pack 2 is installed on your PC, proceed as follows:
1. Make sure that your Easy Braille is switched on and that no USB cable is
connected to it.
2. Plug the enclosed Bluetooth adapter into a free USB port on your PC. The
Bluetooth software is now installed automatically. This may take a few
minutes.
