Operating the Reader (continued)
Problem
You cannot tell if the numeric keypad is
enabled or disabled.
You scan a reader command, such as
Backlight On, and nothing happens.
When you run an application, the reader
scrolls at line 25 and uses Automatic
Viewport Movement mode regardless of
the way you configured these
parameters.
The reader decodes a bar code label in a
symbology other than the label's actual
symbology.
You cannot scan bar code labels.
You see this message, "Configuration
Manager TSR is not loaded."
You see this message, "Configuration
Manager TSR already loaded."

Solution
You can check if the numeric keypad is enabled or disabled by
pressing and a number. For example, press
what appears on the reader's display:
Display Indicates This State
% The number pad is disabled.
5 The number pad is enabled with Num Lock on.
blank The number pad is enabled with Num Lock off.
The reader commands are disabled. Scan the Enable Override
command shown below to temporarily enable all of the reader
commands. You can also enable or disable reader commands
with IC.EXE. For help, see "Command Processing" in
Chapter 12.

If you want the reader to scroll at another line or use Manual
Viewport Movement mode while running an application, you
must explicitly set those parameters in the application. You can
use, for example, PSK functions.
Try scanning the bar code label again. Make sure you scan the
entire label.
To ensure that the reader can operate quickly and efficiently,
you should enable only the bar code symbologies that you are
going to scan. If you enable multiple symbologies, the reader
may on rare occasions decode a bar code according to the
wrong symbology and produce erroneous results.
See "Scanning Bar Code Labels" later in this chapter.
You typed cfgmgr -d to unload the Configuration Manager
TSR from memory, but it has already been unloaded. No action
