Notice to OEM integrator 

Must use the device only in host devices that meet the FCC/ISED RF exposure category of mobile, 

which means the device is installed and used at distances of at least 20cm from persons.   

This transmitter must not be co-located or operating in conjunction with any other antenna or 

transmitter.   

The end user manual shall include FCC Part 15 /ISED RSS GEN compliance statements related to the 

transmitter as show in this manual(FCC/IC Canada statement).     

Host manufacturer is responsible for compliance of the host system with module installed with all 

other applicable requirements for the system such as Part 15 B, ICES 003.   

Host manufacturer is strongly recommended to confirm compliance with FCC/ISED requirements for 

the transmitter when the module is installed in the host.   

The use condition limitations extend to professional users, then instructions must state that this 

information also extends to the host manufacturer’s instruction manual. 

 

This module is stand-alone modular. If the end product will involve the multiple simultaneously 

transmitting condition or different operational conditions for a stand-alone modular transmitter in a 

host, host manufacturer have to consult with module manufacturer for the installation method in 

end system. 

Any company of the host device which install this modular should perform the test of radiated &   

conducted emission and spurious emission etc. according to FCC Part 15C: 15.247 and 15.209 &   

15.207, 15B class B requirement, only if the test result comply with FCC part 15C: 15.247 and   

15.209 & 15.207, 15B class B requirement. Then the host can be sold legally.   

This modular transmitter is only FCC authorized for the specific rule parts (47CFR Part 15.247   

and 15.407) listed on the grant, and that the host product manufacturer is responsible for   

compliance to any other FCC rules that apply to the host not covered by the modular transmitter   

grant of certification.   

Host manufacturer is strongly recommended to confirm compliance with FCC/ISED   

requirements for the transmitter when the module is installed in the host. 

Must have on the host device a label showing Contains FCC ID: 2AB2Q-LA02303B or IC: 10256A-

LA02303B 

Both FCC ID and IC ID are not to be placed on the host at the same time and only hosts going into the 

US can use the FCC ID and only hosts going into Canada can use the IC ID. 

Antenna: PCB Antenna & 4 dBi 

l'hôte doit utiliser l'instrument uniquement dans des dispositifs qui répondent à la fcc / (catégorie 

d'exposition rf mobile, ce qui signifie le dispositif est installé et utilisé à une distance d'au moins 20
