OFF Factors

The OFF factors refer to various causes that make the system enter the OFF state (suspend state), as

follows:

OFF factor	Description	Suspend
Power switch	System operation can be suspended by holding down the	Normal
	Power switch for more than a second. (see note)
Auto Power OFF	System operation automatically shifts to the suspend state	Normal
(APO)	if key or touch panel operation is not performed for a
	specified period of time.
	The duration until Auto Power OFF occurs can be set and
	modified through the System Menu or system library.
Power OFF by	The system can be made to enter the suspend state by	Normal
Software	calling the system library from the application program.
Power OFF due to	The system will issue an alarm (buzzer) if the remaining	Normal
time-out of low	battery voltage falls below the low main battery voltage
battery voltage	alarm level. If this occurs, recharge the battery or replace
(LB1) alarm	it within ten minutes. If the battery is not charged or
	replaced the system automatically shifts to the suspend
	state to protect the data.
If main battery	If the terminal is used while the LB1 alarm, mentioned	Critical
voltage falls to an	above, is sounding, the main battery voltage may reach
inoperable level	the LB0 level. If this occurs the system will execute the
(LB0)	critical suspend process and forcibly turn off the power.
	Therefore, if the LB1 alarm sounds, recharge or replace
	the battery as soon as possible.

	running at present then turn off the system power with the
	power switch before hand.

For more information about LB0 and LB1, refer to Chapter 2.2.4, "Battery Voltage Monitoring Process".

For information about the system library refer to Chapter 8.6.2. “System Library”. For information about the System Menu refer to Chapter 3 “System Menu”.

For information about the method used by each application to acquire a power ON/OFF event, refer to Chapter 9.5 “Remaining Battery Voltage Display Utility”.

Note:

Hold down the Power switch for more than one second until the power is off. This is done to prevent the power from accidentally being turned off by the user. In addition, key input will not be enabled for approximately one second after the Power switch has been pressed.

This occurs because the monitoring timer starts operating the moment the Power switch is pressed and does not allow key input for about one second until this timer expires.

After this interval, key input becomes possible.
