Compliance and Safety

Compliance

This equipment has been tested and found to comply with limits for a Class A digital device, pursuant to Part 15 of

the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the

equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency

energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to

radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in

which case the user will be required to correct the interference at his own expense. Any unauthorized changes or

modifications to this equipment could void the users authority to operate this device. This device complies with Part

15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause undesired

operation.

Notice

This Class A digital apparatus complies with Canadian ICES-003.

Remarque

Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.

Caution

Only trained personal should open and service the scanner as use of controls or adjustments or performance of

procedures other than those specified herein may result in dangerous laser light exposure. Never attempt to look at

the laser beam, even if the scanner appears to be nonfunctional. Doing so could result in hazardous laser light

exposure. The use of optical instruments with the laser equipment will increase eye hazard.

Standard Europeo

Warning

This is a class A product. In a domestic environment this product may cause radio interference in which case the

user may be required to take adequate measures.

Funkstöreigenschaften nach EN55022:1998

Warnung!

Dies ist eine Einrichtung der Klasse A. Diese Einrichtung kann im Wohnbereich Funkstörungen verursachen. In

diesem Fall kann vom Betreiber verlangt werden, angemessene Massnahmen durchzuführen.

Attenzione

Questo e’ un prodotto di classe A. Se usato in vicinanza di residenze private potrebbe causare interferenze radio che

potrebbero richiedere all’utilizzatore opportune misure.

Attention

Ce produit est de classe “A”. Dans un environnement domestique, ce produit peut être la cause

d’interférences radio. Dans ce cas l’utiliseteur peut être amené à predre les mesures adéquates.

General Precautions

This symbol within the document represents an important HSE Safety requirement/alert.

This symbol within the document represents an important quality step.

Safety Training

Consult the local HSE Cell Risk assessment to become familiar with any potential hazards while working with the

CK75 Mobile Computer with integrated scanner.

HSE training for this Scanner should include;

 Hand and Portable Tools

 Hazardous Chemical Management

 Laser Safety

 Lead Safety

 PPE

 Safety Awareness

Safety glasses must be worn.

Quality Training

Training per the local Honeywell site for Technicians/Repair personal should include;

 Soldering Verification (add any additional training that would be required)

Product ESD Information

This product contains ESD sensitive components or ElectroStatic Discharge sensitive electronic parts. The

Electrostatic discharge is defined as the transfer of charge between bodies at different electrical potentials. An ESD

event has the ability to modify the electrical characteristics of a semiconductor device, possibly degrading or even

destroying it. ESD also may upset the normal operation of an electronic system, causing equipment malfunction or

failure.

ESD PREVENTION STEPS MUST BE USED DURING ANY REPAIRS OR MODIFICATIONS TO THIS

UNIT. PERFORM ALL WORK AT A CERITFIED ESD WORK STATION.

Laser Safety Information

The CK75 Models are rated as CLASS I laser products, as defined by The U.S. Federal Laser Product Performance

Standard (FLPPS): Title 21 of the Code of Federal Regulations; Part 1000; [Parts 1040.10 and 1040.11]. Users of a

Class I laser products are generally exempt from radiation hazard (light emission) controls during operation and

maintenance, but not necessarily during service. As the Technician, it is possible to be exposed to increased

brightness of the laser while the unit is open and lenses/filters are not installed. The concept that the “Human

aversion” reaction to bright light will protect an individual from this light applies, however it is important to note that

at no time should a properly trained Technician/repair person look into/at an operating scanner. Never point an

operating scanner at another person.

Laser Classes

CLASS I, II, and IIA lasers are defined as:

 CLASS I: cannot emit laser radiation at known hazard levels (typically continuous (CW): 0.4microwatts at

visible wavelengths). Users of a Class I laser products are generally exempt from radiation

hazard controls during operation and maintenance (but not necessarily during service).

 CLASS II: low power visible lasers, which emit above Class I levels but emitting a radiant power not

above 1mW. The concept is that the human aversion reaction to bright light will protect a

person.

 CLASS IIA: a special designation that is based upon a 1000 second exposure and applies only to lasers that

are "not intended for viewing" such as a supermarket laser scanner. These laser are emitting

light in the visible wavelengths (0.4 to 0.7 mm) with power not above 1mW.

OPERATION:

Cautions & Notes

 The four outside corner case screws on this product feature an integral sealing material which, when

properly installed, aid in meeting the IP sealing specification. These four screws should not be

reused.

 Take care to keep all cables, wires, and flexible components routed around potential pinch points

during reassembly. Ensure PCB’s and other (electrostatic discharge sensitive) components are

properly protected from ESD.
