Troubleshooting (continued)
USB connections with a computer
Computer does not recognize this unit.
e See page 22 for information about supported operating
systems. Operation with unsupported operating systems is not
guaranteed.
There is noise.
e Starting other applications during playback of an audio file
may interrupt playback or cause noise. Do not start other appli-
cations 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 audio playback software and audio 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 audio 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
Settings are retained even if the power plug is disconnected.
Follow these procedures to restore the factory default settings and
erase all changes in memory.
1

If the unit is on, press the POWER button to turn it off and wait
for more than 30 seconds.

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.
