Host requirements Only Hartvik Engineering AB determines what host that can use this module trough testing to ensure the host comply to the supply voltage requirements and the host/module combination will be tested to correspond to all the regulations noted in the module grant including RF exposure evaluation. The host manufacturer is responsible for compliance to any other FCC-rules that apply to the host, this module only complies to the rules stated in the module grant. Together with the host manufacturer a number of testmodes can be setup to further evaluate the hosts ability to comply to all applicable FCC rules and the module approval is sustained. Testing must be done according to FCC Modular transmitter integration guide KDB 996369 D04. A Class II Permissive Change must be filed to the FCC when a new host is approved. HE1074-915 Radio module Reference manual 4(10) Regulatory conformity summary No modifications to the module HE1074-915 made by other than Hartvik Engineering AB are allowed to ensure that the products approval of FCC and IC regulation is sustained. Modules were tested and found to comply to the regulations using Linx ANT-916-CW-HW-SMA halfwave center-fed dipol antennas, only equal or similar antennas must be used and gain can not exceed 2dBi. Only antennas and other peripheral approved by Hartvik Engineering AB must be used. FCC and Industrial Canada (IC) notices Testing for unintentional radiators of end product with the HE1074-915 built in must be done to verify that it achive approval of FCC rules Part 15 (eg 15.107 and 15.109) respectively IC-003 for Canadian regulations. Labeling The FCC ID of this radio module must be included clearly visible on the final products outside label to comply with part 15 of FCC regulations. Part 15.19(a):
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, and
(2) This device must accept any interference received, including interference that may cause undesired operation. Part 15.105:
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. Part 15.21:
NOTE: The user is cautioned that any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Part 15.247:
NOTE: This equipment will meet the requirements of FCC part 15.247, the same must applies to the host. HE1074-915 Radio module Reference manual 5(10) Regulatory Module Integration Instructions This module has been granted modular approval for mobile applications. OEM integrators for host products may use the module in their final products without additional FCC / IC (Industry Canada) certification if they meet the following conditions. Otherwise, additional FCC / IC approvals must be obtained. The host product with the module installed must be evaluated for simultaneous transmission requirements. The users manual for the host product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC / IC RF exposure guidelines. To comply with FCC / IC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed 2dBi. A label must be affixed to the outside of the host product with the following statements:
This device contains FCCID: 2ASTV-1074-915. The final host / module combination may also need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. If the final host / module combination is intended for use as a portable device (see classifications below) the host manufacturer is responsible for separate approvals for the SAR requirements from FCC Part 2.1093 and RSS-102. Device Classifications Since host devices vary widely with design features and configurations module integrators shall follow the guidelines below regarding device classification and simultaneous transmission, and seek guidance from their preferred regulatory test lab to determine how regulatory guidelines will impact the device compliance. Proactive management of the regulatory process will minimize unexpected schedule delays and costs due to unplanned testing activities. The module integrator must determine the minimum distance required between their host device and the users body. The FCC provides device classification definitions to assist in making the correct determination. Note that these classifications are guidelines only; strict adherence to a device classification may not satisfy the regulatory requirement as near-body device design details may vary widely. Your preferred test lab will be able to assist in determining the appropriate device category for your host product and if a KDB or PBA must be submitted to the FCC. Note, the module you are using has been granted modular approval for mobile applications. Portable applications may require further RF exposure (SAR) evaluations. It is also likely that the host / module combination will need to undergo testing for FCC Part 15 regardless of the device classification. Your preferred test lab will be able to assist in determining the exact tests which are required on the host / module combination. HE1074-915 Radio module Reference manual 6(10) FCC Definitions Portable: (2.1093) A portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is / are within 20 centimeters of the body of the user. Mobile: (2.1091) (b) A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitters radiating structure(s) and the body of the user or nearby persons. Per 2.1091d(d)(4) In some cases (for example, modular or desktop transmitters), the potential conditions of use of a device may not allow easy classification of that device as either Mobile or Portable. In these cases, applicants are responsible for determining minimum distances for compliance for the intended use and installation of the device based on evaluation of either specific absorption rate (SAR), field strength, or power density, whichever is most appropriate. Simultaneous Transmission Evaluation This module has not been evaluated or approved for simultaneous transmission as it is impossible to determine the exact multi-transmission scenario that a host manufacturer may choose. Any simultaneous transmission condition established through module integration into a host product must be evaluated per the requirements in KDB447498D01(8) and KDB616217D01,D03 (for laptop, notebook, netbook, and tablet applications). These requirements include, but are not limited to:
Transmitters and modules certified for mobile or portable exposure conditions can be incorporated in mobile host devices without further testing or certification when:
Or Antenna separation distance and MPE compliance requirements for ALL simultaneous transmitting antennas have been specified in the application filing of at least one of the certified transmitters within the host device. In addition, when transmitters certified for portable use are incorporated in a mobile host device, the antenna(s) must be >5 cm from all other simultaneous transmitting antennas. All antennas in the final product must be at least 20 cm from users and nearby persons.
