MP3 player devices cannot be controlled through the
USB connector. Some player devices save music files in
MP4 format, which cannot be played in this radio. Some
copy protected music (e.g., downloads from the internet)
cannot be played on this radio.
NOTE: Some MP3 Players do not allow songs to be
copied into other devices.
How to Open the Cover
1. Place finger under the pull arrow and pull forward.
NOTE: The flap is attached and should not be removed!
Do not use a tool (e.g. screw driver, nail file, etc.) to open
the flap, as this could cause damage to the face of the
radio.
