3 Applications
The CD / MP3 player CD-112 / BT with Bluetooth

tions (e . g . in theatres, pubs or waiting rooms)
and offers special features, e . g . continuous

titles in MP3 format . However, problems may
occur when replaying rewriteable CDs (CD-RW)
depending on the type of CD, the CD burner

dling may result in electric shock!

vated when the jumper is in the position AUTO
PLAY . To deactivate the function, re arrange the
jumper to the position MANUAL PLAY .
