MAINTAINING YOUR SEGA CD
The Sega CD's Location
• Set up the Sega CD in a well-ventilated area. Position it on a stable,
flat surface that is not prone to vibration.
• Keep your Sega CD out of direct sunlight and away from extreme hot
or cold temperatures, such as near a heater or in an uninsulated garage.
• Don't let the Sega CD get wet. Avoid using it in humid areas.
If condensation forms on the console, wipe it dry, and let the
system rest for at least an hour before using it.
The Console
• Insert only 8cm or 12cm discs into the disc tray. Do not use discs
designed for other game units.
• Always use the Open button to open and close the CD door.
Attempting to operate the CD door manually may cause it to
malfunction.
• Do not open the CD door when a Sega CD game is playing.
• Always remove a disc before moving the console.
• Do not take the console apart or alter it in any way. Never touch the
connectors, or insert foreign objects into the connector terminal.

or pull the cables forcefully. Doing so may damage their connections.
• Don't spill liquids onto the console or into the disc tray.
• Clean the console with a soft, slightly damp cloth. Never use strong
cleaning solutions or abrasives that could damage the components.
