Quick Reference Guide 3
Introduction
This guide is designed to assist during routine LS7808 operation. Detailed
information about unpacking, installation, performance specifications,
programming and troubleshooting can be found in the LS7808 Product
Reference Guide (p/n 72E-73952-XX).
Product Description
The Symbol LS7808 horizontal slot scanner is a high performance,
omni-directional scanner that supports high throughput applications at the point of
sale (POS). The scanner reads all retail symbologies and has multi-interface
capability to interface to all popular POS devices. The scanner is designed for
horizontal in-counter mounting and allows slide-through scanning of items
enhancing productivity and throughput. The scanner has an integrated Electronic
Article Surveillance (EAS) antenna for use with Checkpoint®EAS systems.
The LS7808-SR20007TCR features standard tin oxide glass, and the
LS7808-SR2X009SCR features scratch proof sapphire glass.

Operating the Scanner
Parts
Power
The LS7808 does not have an on/off switch. It is ready to scan when
connected to a power supply.
Indicator Lights
The scanner employs an LED with a combination of red and green lights
to indicate operation and decode status. See LED Definitions on page
10 for the different light combinations and their meanings.
If the scanner is not operating normally, contact the technical person in
charge of scanning, or call Motorola Enterprise Mobility Support (see
details on the back cover).

Sleep Mode
The scanner automatically enters Sleep mode when it has been inactive
for a specified length of time. The scanner has two levels of sleep: laser
and motor. In laser sleep mode, after ten seconds of inactivity the laser
pulses at a 50% rate, and then drops to 3% after a specified time. In
motor sleep mode, the scanner is programmed to turn off the motor and
the laser.
To wake the scanner from sleep mode, present a bar code at the scanner
window.
Beeper Volume
The scanner emits a short beep when it successfully reads a bar code.
The volume of the beep is changed electronically by a command sent by
the host, or by scanning one of the beeper volume bar codes in the
LS7808 Product Reference Guide. See Beeper Definitions on page 8.
Connections
The scanner’s ports are at the lower edge of the scanner. Remove the
connection cover to access the ports.

Routing the Cables
The scanner case has several channels to route the outgoing cables so
that they are organized and don’t hinder the scanner’s placement. After
placing the cable connectors in the appropriate scanner ports, route the
cables through the nearest channel.
For a cable with a Y-connector (containing both power and interface
connectors):
1. Connect the power and interface cables to the appropriate ports.
2. Route the cables according to the following diagram.
Installing the Scanner
The LS7808 mounts in the counter with the face of the scanner flush with
the counter top. Refer to the LS7808 Product Reference Guide for
detailed installation instructions.

Quick Reference Guide 7
Scanning Bar Codes
Install and program the scanner. Refer to the LS7808 Product Reference
Guide for programming instructions. For assistance, contact the local
supplier or Motorola Enterprise Mobility Support (see details on the
back cover).
To scan a bar code:
1. Ensure all cable connections are secure.
2. Orient the item with the bar code facing the scanner window.
3. Move the item through the active scan area (see page 8) in the
direction of the scan arrow, or place the item in front of the scanner.
4. Upon successful decode, the scanner beeps and the green LED
flashes momentarily.

Active Scan Area
The active scan area, in front of the scanner window, is optimized to scan
items as they move in the direction of the scan arrow.
The dotted areas below represent the active scan area.
Beeper Definitions
The scanner communicates with the user by emitting different beeper
sequences and patterns. See the Beeper Indications table below for
beeper sequences that occur during both normal scanning and while
programming the scanner.
Beeper Sequence Indication
Standard Use
3 high beeps Power up.
High beep A bar code symbol was decoded (if decode beeper is
enabled).
4 long low beeps A transmission error was detected in a scanned symbol.
The data is ignored. This occurs if the scanner is not
properly configured. Check option setting.
5 low beeps Conversion or format error.
High-high-high-low
beeps
RS-232 receive error on RS-232 host or RS-232 auxiliary
port.

Code 39 Buffering
High-low beep New Code 39 data was entered into the buffer.
3 long high beeps Code 39 buffer is full.
Low-high-low beeps The Code 39 buffer was erased or there was an attempt to
clear or transmit an empty buffer.
Low-high beeps A successful transmission of buffered data.
Host Specific
USB only
4 short high beeps Scanner has not completed initialization. Wait several
seconds and scan again.
Scanner gives a
power-up beep after
scanning a USB
Device Type.
Communication with the bus must be established before
the scanner can operate at the highest power level.
This power-up beep
occurs more than
once.
The USB bus may put the scanner in a state where power
to the scanner is cycled on and off more than once. This is
normal and usually happens when the PC cold boots.
RS-232 Host only
High beep A <BEL> character is received and Beep on <BEL> is
enabled.
RS-232 Auxiliary Port only
High beep A complete block of data was received and sent to the
host, either due to a carriage return or because the
two-second serial response timeout has elapsed.
4 long low beeps A data overrun condition has occurred. Abstain from
scanning data from other ports when large amounts of
data are sent to the RS-232 Auxiliary port.

LED Definitions
In addition to beeper sequences, the scanner communicates with the
user via an LED display. The Standard LED Definitions table defines LED
indications that display during scanning.
Maintenance
Cleaning the exit window is the only maintenance required. A dirty or
scratched window may affect scanning activity.
-Remove any dirt particles with a damp cloth.
-Wipe the window with a tissue moistened with ammonia or water.
To clean the exit window:
1. Insert a coin into the large screw heads on the front of the scanner
and turn counter-clockwise.
2. Lift off the window.
3. Wipe clean the underside of the upper window.
4. Wipe clean the top surface of the lower window.
5. Re-install the top cover by tightening the two large screws.
To change the exit window:
1. Remove the window as described above.
2. Replace with a new window.
3. Reinstall the top cover by tightening the two large screws.
LED Indication
Off No power is applied to the scanner.
Green The scanner is on and ready to scan.
Momentary flash A bar code was successfully decoded.
Slow continuous red flashing, green on The scanner is in programming mode.
Fast continuous red flashing, green on There is an internal problem; the laser
