Service Information
If you have a problem with your equipment, contact the Symbol Support Center. Before
calling, have the model number, serial number, and several of your bar code symbols at hand.
Call the Support Center from a phone near the scanning equipment so that the service person
can try to talk you through your problem. If the equipment is found to be working properly
and the problem is symbol readability, the Support Center will request samples of your bar
codes for analysis at our plant.

Setting Up the LS 2106
Introduction
The LS 2106 hand-held laser scanner offers excellent performance in retail and light
industrial applications. Advanced ergonomic design ensures comfortable use for extended
periods of time.
The LS 2100 Series hand-held scanner is based on the SE 1200 Series scan engine, mylar
®
scan element and the Visible Laser Diode (VLD). This state of the art technology gives the
scannera wider decodezone,greater depth offield,and a visiblescan beam. Thismodelreads
color bar codes and symbols printed on all substrates. See the LS 2106 Decode Zone on page
2-4.
Figure 1-1. LS 2106 Scanner
Here’s what each member of the LS 2100 family offers you:
t
LS 2100 - The aggressiveness of this discrete scanner is typical of the
LS 2100 family’s performance. It connects easily to, and is programmed by, the

interface controllers.
t
LS 2104 - With a simple cable change, this scanner is compatible with:
s RS 232C asynchronous terminals
s Synapse

“Smart Cables”, which allow you to connect to:
s Wand Emulation terminals
s IBM 4683/4, 4693/4 series of terminals
All leading OCIA terminals, including NCR, Nixdorf, and ICL terminals.
s Dual RS-232 Hosts
s Popular OCR terminals, such as Fujitsu and ICL.
t
LS2106-TheLS2106scannerisakeyboard“wedge”interfacewhich adds efficient,
reliable bar code reading to your PS/2 or AT/XT terminal. Since entered scan data is
transmitted as keystrokes, no software changes to the host system are necessary. The
scanner contains on-board discrete keyboard wedge communications for connecting
to asynchronous terminals and host systems. It can also accommodate any of the
Synapse™ “Smart Cables” which allows you to connect to a wide variety of host
systems. Some installations require one cable; others require additional adapters
between the keyboard, the PC, and the y-cable.
All of the LS 2100 series scan automatically at the rate of 36 scans per second. For decode
capability, see Technical Specifications on page 3-3.
Audience
The intended audience for this manual is personnel performing installation/setup and
programming of LS 2106 scanners.
Unpacking
Remove the LS 2106 from its packing and inspect it for damage. If the scanner was damaged
in transit, call the Symbol Support Center at one of the telephone numbers listed on page x.
KEEP THE PACKING . It is the approved shipping container and should be used if you ever
need to return your equipment for servicing.

Installing the Cable
Insert the cable into the receptable on the bottom of the scanner, as shown below:
Figure 1-2. Installing the Cable
Switching Cables
Different cables are required for different hosts. To change the scanner cable:
1. Press the tab on the cable with a small screwdriver.
2. Pull the cable out of the receptacle on the bottom of the scanner.
3. Insert a new cable in the receptacle. Press the cable into the receptacle until you hear
a click.

Chapter 2
Scanning with the LS 2106
Introduction
This chapter covers the proper techniques for scanning bar codes and the decode zone for the
LS 2106 scanner.
Scanning with the LS 2106
Before you can use the scanner, it should have already been installed and programmed. If not,
refer to Chapter 4, Parameter Menus for instructions on programming your scanner. If you
need assistance, contact your local supplier or Symbol Techologies.
1. Before you use the scanner, make sure all cable connections are secure.
2. Make sure the bar code is in the correct scanning range. Aim and press the trigger;
the scan beam lights and an orange light illuminates at the rear of the scanner. The
scanner has read the symbol when:
s You hear a beep.
s The orange light turns green.
s The laser turns off.

2-2
LS 2106 Product Reference Guide
Figure 2-1. Holding the Scanner
Aiming the Scanner
Hold the scanner at an angle. Do not hold the scanner directly over the bar code. Laser light
reflecting directly back into the scanner from the bar code is known as specular reflection.
This strong light can “blind” the scanner and make decoding difficult. The area where
specular reflection occurs is known as a “dead zone”.
You can tilt the scanner up to 55°forward or back and achieve a successful decode. Simple
practice quickly shows what tolerances to work within.

2-3
Scanning with the LS 2106
tScan the Entire Symbol
sThe scan beam must cross every bar and space on the symbol (as in the left bar
code below).
sThe larger the symbol, the farther away you should hold the scanner.
sHold the scanner closer for symbols with bars that are close together.
Right Wrong
What DoesThe Beep Mean?
When you hear 1 beep (short high tone) it means data has been decoded successfully. If any
other beeps are heard, contact the technical person in charge of scanning.
When the symbol has been successfully decoded, you will hear a short, high-tone beep, and
the green decode LED will light.
For more specific information on the meanings of the various beeper sounds, refer to Beeper
Indications on page 3-7.

Maintenance and Specifications
Introduction
This chapter covers the appropriate methods for maintaining and the technical specifications
for the scanner.
Maintenance
Cleaning the exit window is the only maintenance required. A dirty window may affect
scanning accuracy.
tDo not allow any abrasive material to touch the window.
tRemove any dirt particles with a damp cloth.
tWipe the window using a tissue moistened with ammonia/water.
tDo not spray water or other cleaning liquids directly into the window.
tDo not remove the nose of the scanner.
Troubleshooting
If, after following the operating instructions, the scanner does not work:
tCheck the system power.
tMake sure the controller is programmed to decode bar codes of the symbology you
are scanning.
tCheck for loose cable connections.

3-2
LS 2106 Product Reference Guide
tMake sure the symbol is not defaced.
tTry scanning test symbols of the same code type.
