Decode UPC/EAN Supplemen-
tal Redundancy
With Autodiscriminate UPC/EAN Supple-
mentals selected, this option adjusts the num-
ber of times a symbol without supplementals
is decoded before transmission. The range is
from two to twenty times. Five or above is rec-
ommended when decoding a mix of UPC/
EAN symbols with and without supplemen-
tals, and the autodiscriminate option is select-
ed.
Scan the bar code below to select a decode re-
dundancy value. Next, scan two numeric bar
codes from the
Product Reference Guide (page
8-12)
. Single digit numbers must have a lead-
ing zero. If you make an error, or wish to
change your selection, scan
CANCEL
in the
Product Reference Guide
(page 8-12).

Linear CodeType Security
Level
(Does not apply to Code 128)
The LS 4800 offers four levels of decode secu-
rity for linear code types (e.g. Code 39, Inter-
leaved 2 of 5). Higher security levels are
selected for decreasing levels of bar code
quality. As security levels increase, the scan-
ner’s aggressiveness decreases.
Select the security level appropriate for your
bar code quality.
Linear Security Level 1
The following code types must be successful-
ly read twice before being decoded:

Bi-directional Redundancy
This parameter is only valid when a
Linear

has been enabled.
When this parameter is enabled, a bar code
must be successfully scanned in both direc-
tions (forward and reverse) before being de-
coded.

UPC/EAN Security Level
The LS 4800 offers four levels of decode secu-
rity for UPC/EAN bar codes. Increasing lev-
els of security are provided for decreasing
levels of bar code quality. There is an inverse
relationship between security and scanner ag-
gressiveness, so be sure to choose only that
level of security necessary for any given ap-
plication.
UPC/EAN Security Level 0
This is the default setting which allows the
scannertooperateinitsmostaggressivestate,
while providing sufficient security in decod-
ing “in-spec” UPC/EAN bar codes.
UPC/EAN SECURITY LEVEL 0
UPC/EAN Security Level 1
As bar code quality levels diminish, certain
characters become prone to mis-decodes be-
fore others (i.e., 1, 2, 7, 8). If you are experienc-
ing mis-decodes of poorly printed bar codes,
and the mis-decodes are limited to these char-
acters, select this security level.
UPC/EAN SECURITY LEVEL 1

Revision A: July 1997
10-36
UPC/EAN Security Level 2
Ifyou areexperiencing mis-decodesof poorly
printed bar codes, and the mis-decodes are
not limited to characters 1, 2, 7, and 8, select
this security level.
UPC/EAN SECURITY LEVEL 2
UPC/EAN Security Level 3
If you have tried Security Level 2, and are still
experiencing misdecodes, select this security
level. Be advised, selecting this option is an
extreme measure against mis-decoding se-
verely out of spec bar codes. Selection of this
level of security significantly impairs the de-
coding ability of the scanner. If this level of se-
curity is necessary, you should try to improve
the quality of your bar codes.
