Automatic Power
Depending on the application, other events, discussed below, may turn a terminal on or off.
Power On
•
The system powers on when a key other than <PWR> is pressed.
•
The system powers on when a scanner trigger is pressed.
•
The program powers on the system at a preset time to perform unattended
operations, such as an overnight communications session.
•
The program powers on the system in response to a modem ring or an RS-232
device connected to the RJ connector.
Power Off
If not used for a period of time determined by the application, the system powers off
automatically to conserve power.
Forcing Power Off
If a terminal freezes in the middle of operation, pressing <PWR> does not power it off. You
can force the system to power off, which reduces the drain on the batteries until you can
download any collected data to the host system.
To force the system to power off, press and hold <PWR> for 15 seconds.
Since the terminal is still frozen at this time, turning the power back on does not solve the
problem. To recover the data held in memory, perform a warm boot (refer to
Terminal
on page 4-5).
Restarting After a Forced Power Off
If you must power down a terminal because of defective software, the System Administrator
should restart the system using the warm or cold boot procedures in the following section.
Note: Do not use the power key to restart if the terminal was forced off due
to defective system or application program software in NVM.
Pressing <PWR> only causes the program to resume where it left
off, trying to perform the same unsuccessful operation.
