This terminal has the Auto Power ON function which automatically starts the system. This Auto
Power ON function can operate in one of the following three ways:

Auto Power ON function (only affects the resume process) activated by alarm
The system power can be turned on (resumed) at the specified time by means of an alarm.
However, this will not function if the next start-up method is set to the boot process in the system
library.

Auto Power ON function activated by the RING signal
This function can be used if a modem is connected to the 14-pin expansion interface. In this case
the system power can be turned on by the detection of the RING signal from the modem.
Remember that Power ON by means of the RING signal is prohibited by default. Execute this
function using the system library to enable the Power ON function to be activated by the RING
signal. System operation after the power is turned on follows the sequence described in "
Relationship between OFF Factors and ON Processes" on this page.

Auto Power ON activated by mounting on the I/O Box
The system power can be automatically turned on as soon as this terminal is mounted on the I/O
Box. However, this function is effective only if power is supplied to the I/O Box. This function is
enabled by default, however, it can be disabled using the system library. System operation after
the power is turned on proceeds according to the sequence described in "Relationship between
OFF Factors and ON Processes".
Relationship between OFF Factors and ON Processes
As described in the above overviews, the ON process (the Boot process or Resume process) will run
differently depending on the last OFF factor (what caused the OFF) and the conditions that existed
when the power was turned OFF. The following table shows the relationship between the OFF
factors and the ON processes that take place the next time the power is turned on.
