intentional radiator is reduced by the amount in dB that the directional gain of the 
antenna exceeds 6dBi. 

3.  The operator of a spread spectrum system and the user of the radio device are each 

responsible for ensuring that the system is operated in the manner outlined in the section 
on Interference Environment above. 

The 915B radio with its certified antennas complies with these requirements when installed 
correctly as detailed in this manual. 

The 915B radio has Industry Canada (IC) Certification Number 4309B-915B. 
Operators must be familiar with IC RSS-210 and RSS-102. The 915B has been designed and 
manufactured to comply with IC RSS-210 and RSS-102.  
This device has been designed to operate with the antennas listed below and having a maximum 
antenna system gain

1

 of 8.7 dBi. Antenna types not included in this list or having a systems gain 

greater than 8.7 dB are strictly prohibited for use with this device. The required antenna 
impedance is 50 ohms. 
To reduce potential radio interference to other users, the antenna type and its gain should be so 
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted 
for successful communication. 

I

t is the responsibility of the operator to ensure that the public is not exposed to excessive Radio 

Frequency (RF) levels. The applicable regulations can be obtained from local authorities.  
WARNING  

To comply with FCC RF exposure limits, the antenna must be fix-mounted to provide 
a separation distance of 30cm (12 inches) or more from all persons to satisfy RF 
exposure requirements. The distance is measured from the nearest point of the 
modem to the human body. It is recommended that the modem be installed in a 
location with minimal pathway disruption by nearby personnel. 

 
WARNING  

Outdoor antennas must be installed professionally. The installer must 
understand applicable FCC or Industry Canada rules regarding antennas. 
Only the approved antenna types with gains up to the specified maximum can 
be used with the 915B Radio and its final products. Installer must also 
understand and follow electrical codes that apply to installing outdoor 
antennas.

 Antenna system gain is defined here as the antenna gain in dBi as published by the manufacturer MINUS all 

losses due to cables, connectors, or devices (e.g. Cavity filters, surge protectors) installed between the 915B 
Radio Module RF port and the antenna port.
