Pause mode
When you press the pause button located on the back of AIBO, the back light turns
off and power is shut down. Be sure to have AIBO in this mode before changing/
replacing the battery or replacing the "Memory Stick." To start up AIBO, press the
pause button on the back again. The back light turns on green, and AIBO starts
moving around.
Where is the name of the pause button derived from?
Unlike other conventional home electrical products, AIBO has no Power switch
since AIBO is designed as an "autonomous robot that moves and learns on its own
will while communicating with its surroundings." AIBO carries out autonomous
actions when it wants to play, while it asks you to charge it when its battery power
grows weak. When it feels sleepy, it enters Sleep mode on its own to rest. Although
you can have AIBO enter Sleep mode to sleep, it wakes up when it wants to.
Therefore, no Power switch is necessary for AIBO.
However, when you need to stop AIBO in an emergency, press the "pause button" to
temporarily stop AIBO's movement. We, therefore, call the button located on
AIBO's back the "pause button" instead of the "power button."
