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. Note: This equipment has been tested and found to comply with the 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. The RM5800 complies with Part 15.247 modular (Intentional Radiator) FCC rules and regulations. Changes or modifications not expressly approved by Rosemount Inc. could void the user's authority to operate the equipment. 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. Cet appareil est conforme à la norme RSS Industrie Canada exempt de licence. Son fonctionnement est soumis aux deux conditions suivantes: (1) cet appareil ne doit pas provoquer d’interférences et (2) cet appareil doit accepter toute interférence, y compris les interférences pouvant causer un mauvais fonctionnement du dispositif. 7.1 FCC Testing In order to fulfill FCC certification requirements, products incorporating the RM5800 must comply with the following: 1. An external label must be provided on the outside of the final product enclosure specifying the FCC identifier as described in 7.3 below. 2. The antenna must be electrically identical to the FCC-approved antenna specifications for the RM5800 as described in 7.2 with the exception that the gain may be lower than specified in Section 7.2 3. The device integrating the RM5800 may not cause harmful interference, and must accept any interference received, including interference that may cause undesired operation. 4. An unintentional radiator scan must be performed on the device integrating the RM5800, per FCC rules and regulations, CFR Title 47, Part 15, Subpart B. See FCC rules for specifics on requirements for declaration of conformity.

Note: The following FCC rule (15.203) must be ensured in the final design of the product. This can be done by either ensuring the professional installation of the final product (See Ref 1) or designing it in such a way as to make the antenna integral to the final product (See Ref 2). Further, the RM5800 is only for sale to OEM’s and is not available to the general public. The RM5800 is an industrial network communication module and only works on Wireless Hart protocols and as such is part of an industrial process control system professionally installed and maintained. Ref 1 (1) Installation must be controlled. (2) Installed by licensed professionals (e.g., device sold to dealer who hire installers). (3) Installation requires special training (e.g., special programming, access to keypad, field strength measurements made). Ref 2 (1) Use of permanent, industrial epoxy, “Loctite” or solder to make the connection permanent prior to shipping. (2) Allow use of standard connectors if the transmitter has a sensing circuitry that disables the transmitter if an unauthorized antenna is used. An application should detail how this is accomplished. (3) Use of a standard connector is also allowed if the connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter, where such disassembly is not normally required. The user manual must not show that user has access to the connector. (4) BIOS lock—Radio card and host (e.g., laptop computer) exchange code to ensure only the authorized transmission system works in the host. CFR Title 47, Chapter 1, Subchapter A, Part 15, Subpart C, Section 15.203 Antenna Requirement An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of § 15.211, § 15.213, § 15.217, § 15.219, or § 15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection
Confidential RM5800 Datasheet Rosemount Inc. 10 of 10 systems and some field disturbance sensors, or to other intentional radiators which, in accordance with § 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded. 7.3 Final FCC Labeling Requirements The outside of the final product enclosure must have a label with the following (or similar) text specifying the FCC identifier. The FCC ID and certification code must be in Latin letters and Arabic numbers and visible without magnification. Contains transmitter module FCC ID: LW2-RM5800 Or Contains FCC ID: LW2-RM5800 7.4 IC Testing The RM5800 is certified for modular Industry Canada (IC) RSS-210 approval. The OEM is responsible for its product to comply with IC ICES-003 and FCC Part 15, Sub. B - Unintentional Radiators. The requirements of ICES-003 are equivalent to FCC Part 15 Sub. B and Industry Canada accepts FCC test reports or CISPR 22 test reports for compliance with ICES-003. 7.5 Final IC Labeling Requirements The Original Equipment Manufacturer (OEM) must ensure that IC labeling requirements are met. The outside of the final product enclosure must have a label with the following (or similar) text specifying the IC identifier.
