• Tap the stylus on the + sign next to Options to display these parameters.
Dot Time (msec)
The value selected for "Dot Time (msec)" determines (in milliseconds) how long
the targeting dot remains on before the scanner switches to a normal scan sweep.
When you double-tap on this parameter, a dialog box is displayed in which you can
enter a value from 0 to 3000. A value of (zero) disables the target dot.
0
Short Code
When enabled, this parameter allows scanning of short I 2 of 5 bar codes (2
characters). When disabled, these short bar codes are rejected.
Enabling "Short Code" may reduce the robustness of the decoding since the
hand-held must decode more potential bar codes; it is therefore not recommended
for general-purpose bar codes with 4 or more characters.
Verify
The value entered for this parameter determines the number of correct additional
decodes required after the initial decode, prior to a bar code being accepted. Higher
values significantly increase the time it takes to decode a bar code but also improve
the reliability of the decoded bar code.
Security
This parameter controls the tolerance for decoding edge-to-edge bar codes
(Code 93, Code 128, UPC/EAN). Lower values have a lower tolerance for
misreads, but they also increase the time it takes to decode the bar code. The default
value of is generally a good compromise setting.

5.10.2.2 Code 39

Enabled
Set this parameter to on to enable "Code 39" or off to disable it.
Full Ascii
If this parameter is enabled, the characters +, %, and / are used as escape
characters. The combination of an escape character and the next character
is converted to an equivalent ASCII character.
