About the Battery Pack
Power is supplied to the Cordless Scanner by a rechargeable
battery pack that snaps onto the bottom of the scanner. Each
scannerisshippedwithabatterypack[. Batterypacksare
offeredinachoiceofNickelCadmium(NiCad)cells,as
an entry level solution, or a premium battery pack
based on Nickel Metal Hydride (NiMH) cells.
(See
Battery Specifications, page NO TAG, for the
differences between the two types of battery packs, as
well as storage information.)
Proper Disposal of the Battery Pack
Whenthebatterypackhasreachedtheendofits useful life,
thebatteries shouldbe disposedofby aqualified recycleror
hazardous materials handler. Do not incinerate the battery
pack or dispose of the battery pack with general waste
materials. Contact the Product Service Department (see
page NO TAG) for recycling or disposal information.
North American Charging Information
Since the battery pack is rated for both 110/120 60 Hz and 230/240 volt 50 Hz
applications it may be recharged worldwide. For international charging, to
accommodate the wide variety of electrical outlets, a custom charge strip is
required to charge the batteries. The charge strip supports both versions of
battery packs and is offered for two or six battery pack configurations.
Worldwide Charging Information: Charge Strips
[Order backup battery pack(s) or replacement batteries from your distributor.
Contact your distributor for more information or to order Charge Strips.
•Charge the battery pack immediately before use or at least within a couple
of days of use.
Battery Pack Recommendations
•Remove the battery pack from the power outlet or charge strip within 24
hours after charging is completed. Avoid extended overcharging.
•Periodically fully discharge the battery pack.
•Avoid using the battery pack in extreme temperatures. Do not use or place
thechargestripinlocationsthatareextremelyhotorcold,dustyordirty,very
humid, or subject to vibration.
•Do not disassemble the battery pack or the charge strip. There are no
user-serviceable parts in the battery pack or in the charge strip.
The battery pack is designed to plug into any two prong North American AC
power outlet (110/120 Volt) for direct charging. You need no additional
equipment and you can recharge the pack virtually anywhere.

Charge the Battery Pack by following the steps shown below:
Rechargeable
Battery Pack
➊Plug the battery pack directly into
any common 120 Volt AC outlet.[
➋The LED on the bottom of the battery pack will
light red when the unit is charging; it shows
green when it is fully charged and ready to use.
To charge more than one battery pack
(or to charge the pack for all other
countries), use the Charge Strip.
➌Afterthebatterypackisfullycharged,attachittothe
Cordless Scanner by pressing the pack firmly (align
the prongs on the pack with the mating receptacles)
in the base of the scanner until the release buttons
click, holding the pack firmly in place.
(When you
attach a charged battery pack to the Cordless
Scanner, you will hear a single beep.)
➍If you haven’t set up your Cordless System, turn to the next page for
instructions.
Charging Your Battery Pack
[Plug the battery pack into a wall socket in North America only . Failure to
comply could result in equipment failure.
When the battery pack needs recharging, the yellow LED on top of the scanner
pulses in short, continuous blinks and the scanner won’t beep when you pull the
trigger. Ifthe LEDstopsflashing when thetemperature lowers oryou do notuse
the battery pack for some time, you still need to charge the battery pack to avoid
damaging the battery pack or causing scanner memory loss.

➊Make sure the Cordless Scanner’s battery pack has been fully charged.
➋Scan the Association Bar Code (the bar code label on the top of the Base)
to link each scanner to the Base.
The Base stores a unique I.D. for each scanner (up to nine) to identify the
scannerduringdatacommunication. Twobeepsfollowedbyasinglebeepfrom
the scanner indicates a “good” association. The Base rejects a tenth Cordless
Scanner trying to link to its network, sending the scanner an error command. (A
rejected scanner beeps three times, indicating an unsuccessful association.)
[within a 50 foot (15.24 meter) radius of the base, in an open air environment
Note: When you associate more scanners with the Base, you don’t have to
program your Cordless System to communicate with your terminal or computer
if you’ve already completed step 5, above.
Note: After association, if the battery pack is removed from the scanner and
replaced, the scanner will automatically re-associate to the base if the base has
remainedpoweredup. In thiscase,thescannerwill beepon powerupandbeep

Cordless Base
TheCordlessBaseprovidesthelinkbetweentheCordlessScannerandthehost
system. The Base contains a control/interface assembly and an RF
communication module. The RF communication module performs the data
exchange between the Cordless Scanner and the control/interface assembly.
The control assembly coordinates the central interface activities including:
transmitting/receiving commands and data to/from the host system, performing
software activities (parameter menuing, visual indicator support, power-on
diagnostics), and data translation required for the host system.

RF (Radio Frequency) Module Operation
The Cordless System uses a state of the art radio to transmit and receive data
between the scanner and the Base. Designed for point-to-point and multipoint
to single point applications, the radio transmits data at a rate of 1 megabit per
second (MBPS) in a half duplex (2 way) communications mode. The radio
operates using a license free, low power, 2.4 GHz spread spectrum (frequency
hopping) technique. This transmission technique, which sends relatively small
data packets at a fast data rate over a radio signal with randomly changing
frequencies, makes the Cordless System highly responsive to a wide variety of
data collection applications.
The RF radio used in the Cordless System has been tested and approved as
complying with the two leading standards-setting organizations that serve as
regulatorymodels for compliance in mostcountries. InNorth America, the radio
is approved under the standards in FCC B Part 15.249 regulations and, in
Europe, under the standards in ETS 300 328 regulations.
(See page NO TAG
for a chart of regulatory and safety agency approvals.)

Cordless Scanner
The Cordless Scanner enables bar code scanning with non-contact CCD or
Laser input devices, real time decoding, and host connectivity within a 50 foot
(15.24 meter)[radius of the Base unit. It provides the initial bar code data
acquisition function and communicates to the Base. The scanner is comprised
of a CCD or laser scan engine, a decode/control assembly, and an RF
communication module.

[A 50 foot radius is obtained under optimal, “open air” conditions. Signals between
the Base and its scanners need a clear path to communicate, free from RF interference.
The scan engine performs the bar code image illumination and detection. The
decode/control assembly coordinates the central communication activities
including:capturinganddecoding thebarcode imagedata,performingsoftware
activities (parameter menuing, visual indicator support, low battery indication),
and data translation required for the host system. The RF communication

Cordless Systems Manual
Communication Between the Cordless System and the Host
Hostsystemconfirmationmaybeimplementedwithabi-directionalinterfacelike
Host RS-232. In this configuration, when the base unit receives the scanned
data from the scanner and forwards it to the host, the Cordless System waits for
a signal from the host that it received the data. (For information on enabling this
feature and using Host Escape commands, see Host Ack Selection, page
NO TAG).
The Cordless Scanner provides you with immediate feedback in the form of a
“good read” indication (a green LED on the scanner and an audible beep) after
you’ve scanned a bar code correctly and the base has acknowledged receiving
the data. The Cordless System also provides two way communication between
the Scanner and the Base or host system.
If the Cordless System is configured for a keyboard wedge host interface, a
signal (ACK) is sent from the Base confirming that the data was received and is
being sent on to the host system. (Since keyboard wedge interfaces cannot
provide bi-directional communications, they do not permit host confirmation.)
Acknowledgement from the Base
Acknowledgement from the Host System
When data is scanned, the data must be accurately sent to the host system via
the Base unit. Confirmation from the host system or the Base tells you that the
datasentwasreceivedbythehost. TheCordlessScannerrecognizestwoforms

Accessories for the Cordless System
Several accessories are available for the Cordless System. Contact your
distributor for more information or to order accessories.
Belt Holster
The belt holster holds the Cordless Scanner when not in use. The belt holster
consists of a foam covered wire frame clasped to an adjustable nylon web belt
designed to be worn around the waist.
Wall Mount Kit (Standard)
The standard wall mount holder stores the Cordless Scanner on a vertical
surface for convenient access. The scanner easily slides between two
rubberized fingers that hold the scanner when it is not in use.
Wall Mount Kit (Industrial)
Similartothestandardwallmountholder,therubberizedfingersontheindustrial
wall mount holder are smaller to maintain a firm grasp on the scanner under
jolting and jarring conditions, such as those expected in fork lift applications.

power cord between the charge strip and the electrical AC outlet.
Battery Packs
Twotypesofbatterypacksareavailable. Eachpermanentlysealedbatterypack
contains four rechargeable “AA” cells, plus circuitry to allow recharging via
standard AC power outlets (eliminating cumbersome and expensive custom
charging stations). The entry level battery pack contains NiCad battery cells,
while the NiMH battery pack is the premium battery choice with its longer
operating and shorter charging time. Each scanner is shipped with one battery
pack. Order back up batteries or replacement batteries separately.
Note: International versions of the power cords are provided by Welch Allyn’s
country partners. Welch Allyn does not supply these power cords.
