WSS 1000 Product Reference Guide
Automatic Power
A number of other events may turn a wrist computer on or off, depending on the application.
Some of these are:
Power On Via System Control
•
The system powers on when a key other than the Power button is pressed.
•
The system powers on when a scanner trigger is pressed.
•
The application powers the system on at a preset time to perform unattended
operations such as an overnight communications session.
•
The application powers the system on when the wrist computer is placed in the
cradle.
Power Off
The system powers off automatically to conserve power if it is not used for a specific period
of time, as determined by the application program.
Forcing Power Off
If the WWC 1000 freezes in the middle of an operation, pressing the power switch 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 the Power button for 15 seconds.
Since the WWC 1000 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
Booting the
WWC 1000 on page 6-3 ).
Restarting After Forced Power Off
If an operator is forced to power down the WWC 1000 because of defective software, 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 WWC 1000 was forced off
due to defective system or application program software in NVM.
Pressing the Power button only causes the program to resume where
it left off, trying to perform the same unsuccessful operation.
