This equipment should beinstalled and operated with a minimum distance of 20 cm between the radiator and persons. This transmitter must not be co-locatedor operating in conjunction with any other antenna or transmitter, except in accordance with FCC multi-transmitter product procedures.FCC Part 15 Class B Certifications and Regulatory Information (USA Only)All Wireless Vehicle Bus Adapter products comply with the FCC Part 15 Class B standards cited in this section:
Hardwarefile:///C|/Doc%20Projects/TechPubs/Dreamweaver%20projects/90001930%20Wireless%20Vehicle%20Bus%20Adapter%20Application%20Developers%20Guide/Files/hardware.html[12/6/2013 6:29:00 PM]Radio Frequency Interface (RFI) (FCC 15.105)This device has been tested and found to comply with the limits for Class B digital devices pursuant to Part 15 Subpart B, of the FCCrules. These limits are designed to provide reasonable protection against harmful interference in a residential environment. Thisequipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instructionmanual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in aparticular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined byturning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures:Reorient or relocate the receiving antenna.Increase the separation between the equipment and receiver.Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.Consult the dealer or an experienced radio/TV technician for help.Labeling Requirements (FCC 15.19)This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) this device may not causeharmful interference, and (2) this device must accept any interference received, including interference that may cause undesiredoperation.If the FCC ID is not visible when installed inside another device, then the outside of the device into which the module is installed mustalso display a label referring to the enclosed module FCC ID.Modifications (FCC 15.21)Changes or modifications to this equipment not expressly approved by Digi may void the user’s authority to operate this equipment.Industry Canada (IC) CertificationsThis device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may causeundesired operation of the device.Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'encompromettre le fonctionnement. Safety Statements5.10 Ignition of Flammable AtmospheresWarnings for Use of Wireless DevicesObserve all warning notices regarding use of wireless devices. Potentially Hazardous AtmospheresObserve restrictions on the use of radio devices in fuel depots, chemical plants, etc. and areas where the air contains chemicals orparticles, such as grain, dust, or metal powders, and any other area where you would normally be advised to turn off your vehicleengine.Safety in Hospitals
Hardwarefile:///C|/Doc%20Projects/TechPubs/Dreamweaver%20projects/90001930%20Wireless%20Vehicle%20Bus%20Adapter%20Application%20Developers%20Guide/Files/hardware.html[12/6/2013 6:29:00 PM]Wireless devices transmit radio frequency energy and may affect medical electrical equipment. Switch off wireless devices whereverrequested to do so in hospitals, clinics, or healthcare facilities. These requests are designed to prevent possible interference withsensitive medical equipment.PacemakersPacemaker manufacturers recommended that a minimum of 15cm (6 inches) be maintained between a handheld wireless device anda pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with independent researchand recommendations by Wireless Technology Research.Persons with Pacemakers:Should ALWAYS keep the device more than 15cm (6 inches) from their pacemaker when turned ON.Should not carry the device in a breast pocket.If you have any reason to suspect that the interference is taking place, turn OFF yourdevice.Back to Introduction | Forward to Web Services Copyright ©2013 Digi International Inc.
