Changing the Auto Sleep Time Value
Auto Sleep Time is a function that automatically puts the machine into the sleep mode if it remains idle for a
specied length of time. We recommend using the factory default settings ( <Timer/Energy
Settings>(P. 301) ) to reduce power usage. If you want to change the amount of time that elapses before the
machine enters the auto sleep mode, perform the procedure below.
<Menu> <Preferences> <Timer/Energy Settings> <Auto Sleep Time> Set the amount of
time that elapses before the machine automatically enters sleep mode
<Apply>( )
Changing the Sleep Mode Setting to the Specied Time
You can congure a setting so that the machine is placed into the sleep mode at the specied time. You can also
congure a setting so that the sleep mode is released at the specied time.
