antenna.

The noises may be caused by fluorescent lamps, motors,
thermostats, or other electrical equipment. It is difficult to completely eliminate noise. It may be reduced by using an outdoor
AM antenna.

presets.

Problem Cause Remedy
The unit does not detect the USB device.
The USB device is not connected to the USB jack securely. Turn off the unit, reconnect your USB device, and turn the unit on again.
The file system of the USB device is not FAT16 or FAT32. Use a USB device with FAT16 or FAT32 format.
Folders and files in the USB device cannot be
viewed.
The data in the USB device is protected by the encryption. Use a USB device without an encryption function.

properly.
Enable the DHCP server function on your router and set “DHCP” in the “Setup”
menu to “On” on the unit (p.77). If you want to configure the network parameters
manually, check that you are using an IP address which is not used by other
network devices in your network (p.77).
