The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturers instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the pro- vided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10.

Windows 7 Installation: To use the Bryston BDA2 as a USB sound device, the Windows operating system requires additional USB drivers to be installed. These drivers can be found on the Bryston USB key that is included in the box. Connect the Bryston BDA2 to your computer. Plug the Bryston USB key into a USB port on your computer. In windows explorer, navigate to the Bryston USB key (BRYSTON_USB). Now run the file called “setup.exe”. The following window will open: Click the “Next ” button. Install the Bryston USB Audio drivers in the default folder, or change the installation folder if required. Click the “Install” button. CONTINUED ON NEXT PAGE USB AUDIO CLASS 2 DRIVER INSTALLATION A Windows security warning will pop up twice. The USB drivers are safe to use, so select: “Install this driver software anyway” The setup wizard will copy all the necessary files and preinstall the drivers. After successful installation, the following window will open. Click the “Next ” button. The setup wizard is finished and Windows will now install the Bryston USB audio drivers. The Bryston BDA2 D/A is now ready to use as a sound device in Windows. 300032_buc1_20131218
