Checking USB input 1) Use a USB cable to connect the USB port on the back of this unit to the computer. 2) First, start the computer, and launch TEAC HR Audio Player. 3) Press the units standby/on () button to turn it on. Press the SOURCE button on the front of the unit repeatedly until the USB input indicator LED lights. 4) Use TEAC HR Audio Player to open (Fig-1-1) the DSD (Fig-1- 2) file saved on the computer. 5) Select the file shown in TEAC HR Audio Player and press the PLAY button (Fig-1-3). 6) Gradually turn the VOLUME knob on the front of the unit clockwise and confirm that sound is coming from the speakers, including the subwoofer. After confirming this, return the VOLUME to its “MIN” (mini- mum) position. 7) Quit TEAC HR Audio Player on the computer and end the USB connection between this unit and the computer. Confirm that the USB input indicator blinks when you do this. 3. Checking Bluetooth input 1) Press the SOURCE button on the front of the unit repeatedly until the Bluetooth input indicator LED lights. 2) Use the other Bluetooth device to pair or connect with this unit. To ready this unit for pairing, after putting it into Bluetooth mode, press and hold the SOURCE button for at least 3 sec- onds. When the unit is ready for pairing, its Bluetooth input indicator will begin flashing rapidly. If the other Bluetooth de- vice requires the input of a passcode on its setting screen, input “0000” (four zeros). 3) When the unit confirms connection with the other Bluetooth device, its Bluetooth input indicator will stop flashing, but stay lit. Start playback of an audio file on the other Bluetooth device, gradually turn the VOLUME knob on the front of the unit clockwise and confirm that sound is coming from the speakers, including the subwoofer. After confirming this, return the VOL- UME to its “MIN” (minimum) position. 4) End the connection with the other Bluetooth device, and con- firm that the Bluetooth input indicator starts blinking. 2.
