Command Keys
The following are the command keys of the V
x
810:
CANCEL Key
Pressing the CANCEL key in normal mode – when an application is loaded and
running – terminates the current function or operation.
In system mode, use CANCEL to perform a variety of functions. The most
common use of CANCEL in system mode is to exit a system mode submenu and
return to the main system mode menu. The specific effect of pressing the
CANCEL key depends on the currently active system mode menu.
CLEAR Key
In normal mode, the CLEAR key is commonly used to delete a number, letter, or
symbol on the display screen. Press the CLEAR key one time to delete the last
character typed on a line. To delete additional characters, moving from right-to-
left, press the CLEAR
key once for each character or hold down the CLEAR key to
delete all characters in a line.
In system mode, the specific effect of pressing the CLEAR key depends on the
currently active system mode menu.
ENTER Key
In normal mode, the ENTER key is used to end a procedure, confirm a value or
entry, answer “Yes” to a query, or select a displayed option.
In system mode, press the enter key to begin a selected procedure, step forward
or backward in a procedure, and confirm data entries. The specific effect of the
ENTER key depends on the currently active system mode menu.
Programmable
Function (PF) Keys
The row of four PF keys directly above the keypad from left-to-right are referred to
as PF1, PF2, PF3, and PF4. These keys can be assigned application-specific
functions. Because such functions are often unique and can vary greatly between
applications, they are not discussed in this manual.
The PF keys are also used to navigate through the system mode menus. These
keys are functioning when arrows appear in the display screen above the
associated key, indicating that the keys can be used as follows:
