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.

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.

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.

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.)

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.

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.
