Powering the 3300 On and Off

Since the Series 3300 is a battery powered system, it is important to save as much
power as possible. The period of time that the 3300 can be used before its batteries
must be recharged or replaced can be increased by turning it off when data is not
being entered.
When powered off, the 3300 saves power by not performing any processing or
display functions. However, any programs or data in the system's memory are
retained. When the 3300 is powered up again, the display is restored and
processing continues at the point where it was when the terminal was powered
down.
Powering the 3300 on does not reset the system or its program. When you turn
the system back on, it's program will normally resume in the same place where it
was when it was powered off. The data stored in memory also remains intact.
Before the 3300 powers up, it checks the batteries for enough power to ensure
reliable operation and data storage.

Normal Power On/Off

To turn the 3300 on or off, press On/Off.

Automatic Power-On/Off

A number of other events may turn the 3300 on or off, depending on the applica-
tion program. Some of these are:
• The system may power on when a key other than On/Off is pressed.
• The system may power on when the scanner trigger is pressed.
• The program may power on the system at a preset time to perform unattended
operations such as an overnight communications session.
• The program may power on the system to respond to a modem ring or an RS-
232 device connecting to the DB-25 connector.
• The system may power off automatically if it is not used for some period of
time, as determined by the program.
