Data Entry
Modes
Before you can enter data in the form of ASCII characters, the V
x
810 must be in a
mode that accepts keyed data entry. There are two operating modes:
•
Normal mode: This is the operating mode where an application is present
and currently running.
•
System mode: This is a special, password-controlled operating mode for
performing a variety of test and configuration procedures that cannot be
performed when an application is running.
Entering Normal
Mode
If you turn on a V
x
810 with an application stored in system memory, the
application executes and the device automatically enters normal mode. The
application controls how the keys process transactions and when you can use
specific keys to type characters or respond to prompts.
Entering System
Mode With No
Application Loaded
If you turn on a V
x
810 that does not have an application stored in system memory,
the system prompt

appears. You can enter system mode by
simultaneously pressing F2 and F4 , and entering the password. Once in system
mode, you can configure the device as required or perform downloads.
To know more about system mode operations, see System Mode .
Entering System
Mode While in
Normal Mode
If you enter system mode while in normal mode, the active application is
preempted and system mode takes control of the display and keypad.
Re-entering Normal
Mode From System
Mode
The only way to re-enter normal mode from system mode is to restart the device.
For this reason, once you enter system mode, you cannot return to the previously
active application in the same session.
NOTE
Alternatively, a second method for entering system mode is available – by
simultaneously pressing the
7 and ENTER keys and then entering the password.
But for simplification in this manual, only the first method, simultaneously
pressing
F2 and F4 and entering the password, is mentioned from this point on.
Some application downloads can automatically reset the system mode
password. If your system mode password no longer works, check if an
application download has changed your password.
