Pioneer dvd-u05s Operating Instructions Manual page 13

Do not attempt to insert more than two discs at one time, nor insert discs
during play.
Do not insert the disc with excessive force so that it bends nor attempt
to insert it by force. While the unit is pulling in or ejecting discs, do not
attempt to do the opposite using force as this may cause damage to the
disc or malfunction of the unit.
DISC REMOVAL METHOD
¶ Confirm that the BUSY indicator of the drive is not lit, and then press the Eject
button (0).
¶ Remove the disc after it has been ejected.
Do not place anything within 12 cm (4.72 in.) in front of the unit as this
may obstruct the disc ejection operation of the unit.
