If your Lexus is equipped with an automatic changer, it can
play selected discs or continuously play all the discs set in the
magazine.
When you set discs into the magazine, make sure they face the
correct way. If not, the player will display "Err" and the disc
number.
NOTICE
Never try to disassemble or oil any part of the compact
disc player. Do not insert anything except a compact disc
into the magazine.
The player is intended for use with 12 cm (4.7 in.) discs only.
