Operation with other operating systems cannot be guaranteed.
There is noise.
e Starting other applications during playback of a music file may
interrupt playback or cause noise. Do not start other applications
during playback.
e When the unit is connected to a computer via a USB hub, for
example, noise might be heard. If this occurs, connect the unit
directly to the computer.
Audio files cannot be played back.
e Connect the computer with this unit and switch to "USB in"
before starting the music playback software and music file play-
back. Audio data might not play back correctly if you connect
this unit with the computer or change its input to "USB in" after
starting the music playback software.
Since this unit uses a microcontroller, external noise and other
interference can cause the unit to malfunction. In such a case,
turn the unit off and wait about one minute before restarting
operation from the beginning.

Restoring factory settings
Setting changes are retained even when the power cord is
disconnected.
Follow these procedures to restore all settings to their factory
defaults and clear the unit's memory.
1) Turn the unit off.
If the unit is on, press the POWER button to turn it off and wait for
more than 30 seconds.
2) Press the POWER button while holding down the stop (8)
button on the main unit.
Release the stop (8) button when "Setup CLR" (setup clear)
appears on the display.
Note about condensation
If this unit is brought from a cold outdoor environment into a
warm room, or the heater has just been turned on in the room
where it is located, for example, condensation might occur on
operating parts or lenses, resulting in improper operation. If this
occurs, leave the unit on and wait 1-2 hours. This should enable
normal playback.
