Quick Reference
Introduction
The LS 4000P Series hand-held laser scanner offers the best
performance for low volume, price sensitive PDF417 scanning in
retail, office and light industrial applications. It uses a 650nm laser
diode for improved scan-line visibility, and has a scan rate of
approximately 200 scans/second. These factors make the LS 4000P
Series scanner appropriate for PDF scanning while retaining all
capabilities for 1-D scanning.
This Quick Reference Guide provides basic instruction on the
following topics:
•Setting Up the Scanner on page 2
•Scanning on page 4
•What Does The Beep Mean? on page 7
•What If... on page 8

Setting Up the Scanner
Installing the Cable
1. Switch off all devices connected to the LS 4000P.
2. Pull the boot up over the cable until just the connector is pro-
truding.
3. Plug the modular connector on the cable into the receptacle in
the bottom of the LS 4000P handle. Listen for a click.
4. Gently tug the cable to ensure the connector is properly se-
cured.
3
Quick Reference
5. Slide the boot up while observing its orientation until it is se-
curely in place.
6. Make certain the semi-circular key on the boot slides inside
the handle assembly, and that the boot snaps into place.
7. Gently pull the boot to be sure it is properly seated.
Switching Cables
Different cables are required for different hosts. To change the
scanner cable:
1. Slide the boot down over the cable.
2. Unplug the modular connector by depressing the connector
clip (through the access hole), and remove the existing cable.
3. Follow the steps for Installing the Cable on page 2.

Scanning
Scanning 1-D Bar Codes
To scan a 1-D bar code:
1. Make sure all connections are secure, and the symbol you
want to scan is within the scanning range.
2. Aim the scanner at the symbol and press the trigger. The scan-
ning beam remains on for approximately 3.0 seconds (default)
or until a successful decode.
The scanner has read the symbol when:
• You hear a short, high tone beep (if the beeper is enabled).
• The yellow LED on the rear of the scanner turns green.
The green LED stays lit for two seconds or until the next trigger
pull.
Scanning PDF417 (2-D) Bar Codes
The PDF417 bar code type is enabled by default; to disable it, scan
this bar code:
DISABLE PDF417
To enable PDF scanning, scan the bar code below. (These bar codes
can also be found in the LS 4000P Product Reference Guide, p/n
70-37631-xx.
ENABLE PDF417
5
Quick Reference
To scan a PDF417 bar code:
1. Aim the scanner at the PDF bar code and press the trigger.
2. Hold the trigger down and keep the scan line parallel to the
rows of the symbol.
3. Manually raster the scan line by slowly moving the scanner up
and down so it scans the entire bar code at a rate of one inch
per second.
When PDF Decode Feedback is enabled, a clicking noise lets you
know the bar code is being decoded. If this parameter is enabled but
there’s no clicking noise when you’re scanning the bar code, it’s not
being scanned properly.
To improve PDF decoding:
• Check that PDF417 scanning is enabled.
• Make sure the scan line extends at least 1/2” past the left and
right edges of the bar code.
• Hold the scanner closer for denser symbols, farther away for
larger symbols.
• Make sure you scan the top and bottom rows of the symbol.
• Be patient - it may take a few swipes to decode the symbol.
The bar code has been completely decoded when you hear a tone,
followed by a short, high tone beep. The yellow LED on the rear of
the scanner turns green. The green LED stays lit for two seconds or
until the next trigger pull.

Aiming
Scan the Entire Symbol
• Cross every bar and space of the symbol with the scan beam.
• Hold the scanner further away for larger bar codes.
• Hold the scanner closer for symbols with bars that are close
together.
Right Wrong
Hold 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.”
7
Quick Reference
You can tilt the scanner up to 65° forward or back and still achieve
a successful decode. Simple practice quickly shows what tolerances
to work within
What Does The Beep Mean?
When you hear a short, high tone beep, it means data has been
decoded successfully. If any other beeps are heard, contact the
technical person in charge of scanning.

What If...
Nothing happens when you follow the operating
instructions?
You Should
• Check the system power. Is there a battery in the battery box?
• Be sure the scanner is programmed for the terminal in use.
• Make sure the scanner is programmed to read the type of bar
code you are scanning.
• Check for loose cable connections.
• Check the symbol to make sure it is not defaced.
• Try scanning test symbols of the same code type.
