Introduction

This Quick Reference Guide is designed to assist during routine LS 7708

operation. Detailed information about unpacking, installation, performance

specifications, and troubleshooting can be found in the LS 7708 Product

Reference Guide.

Product Description

The LS 7708 high performance omni-directional laser scanner reads bar

codes quickly and accurately with a minimum of effort. The scanner includes

an Electriconic Article Surveillance (EAS) antenna, which allows simultaneous

bar code reading and security tag deactivation.

The LS 7708 can rest on top of a counter or be attached to a mounting surface.

Operating the LS 7708 Scanner

Power

The LS 7708 does not have an on/off switch. It’s ready to scan when connected

to a power supply.

LS 7708 Quick Reference Guide

Indicator Lights

The scanner employs an LED with a combination of red and green lights to

indicate operation and decode status. The Standard LED Definitions Table

on page 13 lists the different light combinations and their meanings.

If the scanner is not operating normally, contact the technical person in

charge of scanning, or call the Symbol Support Center at the telephone

number on the back cover.

Controls

The Volume Control & Wakeup button adjusts the volume of the beeper and

wakes the scanner from rest or sleep mode.

When the scanner is operating, depress this button to adjust the volume. Hold

down the button until the desired volume is obtained (approximately five

seconds). There are three volume levels. The scanner beeps twice at each

volume level before cycling to the next.

If the scanner is in a rest or sleep mode, briefly depressing the Volume Control

& Wakeup button also awakens the scanner.

Connections

The scanner’s ports are at the bottom of the scanner. Turning the scanner

upside down allows access to the scanner’s 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.

Mounting the Scanner to a Surface

Caution: The LS 7708 requires use of the mounting bracket for

proper operation and saftley. Failure to use the bracket

can result in scanner instability.

Connections to power and hand-

held scanner ports, side exit:

curl power cable and route it back

towards interface cable.

Connections to power and host

ports, side exit: keep power cable

straight and route it ahead with

interface cable.

LS 7708 Quick Reference Guide

The LS 7708 is designed to sit on top of a counter or be mounted to a wall. The

slot on the back of the scanner accepts a mounting bracket to secure it to the

mounting surface. This bracket accommodates either configuration.

Attaching the Mounting Bracket

Freestanding Configuration

Use this method if the scanner will not be secured to a mounting surface.

1. Invert the scanner so that its bottom is facing up and the connections

are visible.

2. Connect all interface and power cables to the scanner. Refer to the LS

7708 Product Reference Guide for detailed information.

3. Orient the mounting bracket so that the plastic tab is facing downward

and toward the slot on the back of the scanner. The square cushion on

the mounting bracket should be positioned above the power cable.

Plastic Tab

Rubber Feet

4. Tilt the plastic tab into the slot on the scanner, and rotate the opposite

edge downward. As the bracket rotates, push it toward the slot so that

the feet of the bracket lie flat against the scanner’s bottom (see arrows).

5. When the bracket is flat against the scanner bottom, release pressure

so that the feet slide forward into the front of the scanner.

Mounted Configuration

Use this method if the scanner will be secured to a mounting surface.

1. Determine where the LS 7708 is going to be mounted.

2. Use a pencil to mark the four mounting holes. (A mounting template is

provided in the LS 7708 Product Reference Guide.)

LS 7708 Quick Reference Guide

3. Remove all rubber feet (from the bracket or from the scanner).

4. Place the mounting bracket in position over the drilled holes with its flat

surface facing the mounting surface.

5. Insert four screws through the holes and fasten to the mounting surface.

6. Align the slot at the back of the scanner with the plastic tab on the

mounting bracket.

7. Angle the scanner slightly to allow the bracket plastic tab to slide into

the slot.

8. Push the scanner towards the plastic tab and rotate it so that it is

perpendicular to the mounting surface.

9. Release the pressure on the scanner. The bracket locks into place.

Detaching the Scanner from the Mounting Bracket

To detach the scanner:

1. Grasp the scanner firmly on both sides.

2. Squeeze the back of the scanner slightly while pushing the scanner in

the direction of the slot on the back.

3. Rotate the front of the scanner away from the mounting bracket until the

bracket pops out of the slot.

Scanning Bar Codes

Install and program the scanner. (Refer to the LS 7708 Product Reference Guide

for programming instructions.) For assistance, contact the local supplier or

Symbol Support Center (see back cover for Symbol Support Center phone

numbers).

For the best scanning performance, the counter top or surface area covered by

the active scan area should be free of any designs (e.g. stripes or patterns).

Ideally, that area should be a light, solid color. A rastering omni-directional

scan pattern provides rapid, orientation-free scanning.

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 in the direction of the

arrows, or place the item in front of the scanner.

4. Upon successful decode, the scanner beeps and the green LED flashes

momentarily.

LS 7708 Quick Reference Guide

Active Scan Area

The active scan area is the area in front of the scanner window in which a bar

code can be decoded. The dotted area represents the active scan area.

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.

The scanner is awakened from either sleep mode by pressing the Volume

Control & Wakeup button. In laser sleep mode, the scanner also is awakened

by presenting a bar code at the scanner window.
