• *: The "Operating Mode" here refers to all the modes (and status) other than the Low Power Mode
and Night/Off Mode. Actual power consumption (during the Operating Mode) depends on job
status and environmental conditions.
• **: The SRAM is alive and backs up the engine controller.
AOF
When AOF is off, the engine controller is unable to start the Night/Off Mode. The user should keep AOF
on (User Tools > System Settings > Key Operator Tools > AOF).
Timers
The engine controller references the Energy Saver Timer to start the Low Power Mode, and references the
Auto Off Timer to start the Night/Off Mode. The user can set these timers (User Tools > System Settings >
Timer Settings).
The Energy Saver Timer and the Auto Off Timer start at the same time (t0) when the machine ends all jobs
or when the user ends all manual operations. Note that the Auto Off Timer does not wait for the Energy
Saver Timer. Therefore, if the user specifies a smaller value in the Energy Saver Timer, the Auto Off Timer
expires earlier than the Energy Saver Timer. In a case like this, the Low Power Mode is not activated.
Instead, the engine controller starts the Night/Off Mode when the Auto Off Timer expires.

Any of the following operations brings the machine back to the Operating Mode:
