Inserting or removing a "Memory
Stick"
To play with AIBO, insert an optional "Memory Stick" into AIBO. For details,
refer to the "User's Guide" supplied with the respective AIBO-ware "Memory
Stick." When you start up AIBO without inserting an AIBO-ware "Memory
Stick," it enters clinic mode in which AIBO's sensors and other parts are
checked (page 51).
Inserting a "Memory Stick"
Be sure to insert the "Memory Stick" only after pausing AIBO. When AIBO is
in pause mode, the back light turns off.
