Regulatory Information and Certifications
RF Exposure Guidance
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be
installed and operated with a minimum distance of 20 cm between the radiator and persons. This transmitter must not be co-located
or 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:
file:///C|/Doc%20Projects/TechPubs/Dreamweaver%20projects/90001930%20Wireless%20Vehicle%20Bus%20Adapter%20Application%20Developers%20Guide/Files/hardware.html[12/6/2013 6:29:00 PM]
Hardware
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 FCC
rules. These limits are designed to provide reasonable protection against harmful interference in a residential 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. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning 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 cause
harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired
operation.
If the FCC ID is not visible when installed inside another device, then the outside of the device into which the module is installed must
also 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) Certifications
This 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 cause
undesired 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'en
compromettre le fonctionnement.
Safety Statements
5.10 Ignition of Flammable Atmospheres
Warnings for Use of Wireless Devices
Observe all warning notices regarding use of wireless devices.
Potentially Hazardous Atmospheres
Observe restrictions on the use of radio devices in fuel depots, chemical plants, etc. and areas where the air contains chemicals or
particles, such as grain, dust, or metal powders, and any other area where you would normally be advised to turn off your vehicle
engine.
Safety in Hospitals
file:///C|/Doc%20Projects/TechPubs/Dreamweaver%20projects/90001930%20Wireless%20Vehicle%20Bus%20Adapter%20Application%20Developers%20Guide/Files/hardware.html[12/6/2013 6:29:00 PM]
Hardware
Wireless devices transmit radio frequency energy and may affect medical electrical equipment. Switch off wireless devices wherever
requested to do so in hospitals, clinics, or healthcare facilities. These requests are designed to prevent possible interference with
sensitive medical equipment.
Pacemakers
Pacemaker manufacturers recommended that a minimum of 15cm (6 inches) be maintained between a handheld wireless device and
a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with independent research
and 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 your
device.
