USB port
(14)
This device has been developed according to the current
level of technology in the USB sector. However, the large
variety of different USB storage media of all kinds being
offered today makes it impossible for us to guarantee full
compatibility with all USB storage media. Because of this, in
rare cases there may be problems with playback from USB
storage media. This is not a malfunction of the device.
1. Press the SOURCE button (7) until the indicator lamp (2)
lights green.
2. Connect a USB storage medium directly. Then the play-
back starts.
Refer to the section "Description of the USB / Bluetooth
Operation Buttons" for operation.
NOTE:
• Always connect a USB storage medium directly to the
USB port to prevent problems.
• This USB port cannot be used to charge external
devices.
CAUTION:
Before you remove the USB storage medium, use the
SOURCE button to switch the unit to a different mode.
