Using the device
1. To charge the built-in battery, connect the micro USB port (8) to a powered-on
computer or another USB charging source using the supplied USB cable. During
charging, the LED lights red. After the end of the max. 3-hour charging process,
the LED turns off.
2. For tethered data transfer, connect the player to socket (6) on the device using

• Turn on the player and activate the Bluetooth® function there. If the device was
previously paired with another device, this device must now be turned off or out
of range.
• Have the player search for Bluetooth® devices and select ‘HD2000NC’ from the
device list for connection.
• After successful connection, the LED lights up constantly blue. A later recon-
nection of the two devices will be established automatically.
