Integration Instructions

3.1 List of applicable FCC rules
This module has been tested and found to comply with part 15.247, and RSS-247 requirements for Modular Approval.
3.2 Summarize the specific operational use conditions
This module can be used in DTU, micro-converter, and other equipment. The input voltage to the module should be nominally 1.9-3.6 VDC ( typical 3.3VDC). The ambient temperature of the module should not exceed 80″C.
3.3 Limited module procedures
NA
3.4 Trace antenna designs
NA
3.5 Antenna
Antenna type: Omni Antenna; Antenna Max. Peak Gain 3 dBi
3.6 Label and compliance information
An exterior label on OEM’s end product can use wording such as the following: “Contains Transmitter Module FCC ID: 2ARNB-HMS101” or “Contains FCC ID: 2ARNB- HMS101”
3.5 RF exposure statement:
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 20cm between the radiator and your body. If the device is built into a host for portable usage, an additional RF exposure evaluation may be required.
3.6 Information on test modes and additional testing requirements
a) The modular transmitter has been fully tested by the module grantee on the required number of channels. modulation types. and modes. it should not be necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g.. where a different antenna may be causing additional emissions).
b) The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry. or physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5. 15.15. and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference have been corrected.

3.7 Additional testing, Part 15 Subpart B disclaimer
The final host/module combination needs 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. The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation of the FCC rules.
When testing the host product, all the transmitters must be operating. The transmitters can be enabled by using publicly-available drivers and turned on. so the transmitters are active. In certain conditions, it might be appropriate to use a technology-specific call box (test set) where accessory devices or drivers are not available. When testing for emissions from the unintentional radiator, the transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any active beacons(if applicable) from the enabled radio(s).
FCC Warning : Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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
ISED RSS Warning : This device complies with Innovation, Science, and Economic Development Canada license-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.
ISED RF exposure statement : This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance 20cm between the radiator& your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
ISED Label Instructions : The outside of final products that contains this module device must display a label referring to the enclosed module. This exterior label can use wording such as: ‘Contains Transmitter Module IC: 24490-HMS101″,or “Contains IC: 24490-HMS101*, Any similar wording that expresses the same meaning may be used. Instructions crefiquetage IC: L’exterieur des produits finis contenant ce module doit afficher une etiquette faisant reference au module indus. Cette etiquette exterieure peut utiliser des libelles tels que: “contient le module emetteur IC: 24490-HMS101″ou “content IC: 24490-HMS101”. tout libelle similaire exprimant le meme sens peut etre

 Basic Operation

4.1 NRF Channel List
Depending on the program. the module can work on 915MHz for North America and 868MHz for Europe. Unless necessary, it’s forbidden to change the module program.

Troubleshooting

If the Sub-1 G module can’t work well, please follow this guideline:
a) Try to repower on the device. If the LED on the module can’t light, please change the module or send the whole device to us.
b) If the LED can light, please change the antenna.
c) After changing the antenna, if it still can’t work, please change the module or send the whole device to us.
