Compact disc player operating tips
Use only compact discs labeled as shown, having no dirt,
damage or warp. Lexus does not recommend using 8 cm
(3.2 in.) discs.
The player is intended for use with 12 cm (4.7 in.) discs only.
Using 8 cm (3.2 in.) discs requires the use of an adaptor, which
could cause tracking errors or interfere with disc ejection.Never attempt to disassemble or oil any part of the player
unit. Do not insert any object other than a disc into the
slot.
Remember there are no user-serviceable parts inside.
A new disc may have rough edges on its inner and outer
perimeter. Remove the rough edges by pressing the side
of a ball-point pen or pencil against the inner and outer
perimeter of the disc as shown.
If you continue to play a disc with rough edges, flakes will fall
on to the signal side of the disc and cause sound skipping or
other problems.
