Precautions for handling the MiniDisc (MD)
The MD is housed in a cartridge, so you can handle it without worrying about dust and fingerprints.
Even so, a dirty or warped cartridge may cause malfunction. Remember the following precautions so
you can enjoy high-quality sound for a long time.
Do not touch the disc in the cartridge directly with your fingers.
Do not open the shutter by hand. Doing so may damage the disc.
Storage location
Avoid storing MDs in a place subject to direct sunlight, high temperature, or high humidity.
Regular care
Wipe off dust and dirt accumulated on the cartridge surface with a dry cloth.
Removing a partially inserted MD
If the “self-lock function” is activated and the MD cannot be removed, push the MD further into the
MD recorder and then press the EJECT button to remove the MD.
