
When the Auto standby is selected, if you do not
press any places on the screen for a specified time
while the rotor is not spinning, the backlight level
becomes darkest and then the refrigerator and fan
stop.

This can lower the electric power consumption of
the centrifuge (*1). (*1: When the backlight level
becomes darkest, the refrigerator and fan might not
stop soon. If the room is hot, the fan might start to
cool the inside of the centrifuge.)

If you press any places on the screen after the
backlight level becomes darkest, the backlight level
becomes the brightness which you adjusted (see
section2-6-3 (4)) and then the refrigerator and fan
can start.

When the Auto standby is selected, press the
button. The Auto standby timeout
setting screen appears (see fig. 2-6-3 (11)). You
can enter the desired numeric value with the
on-screen keypad. You can set to any value in the
range from 1 minute to 180 minutes in increment of
1 minute.
