 WARNING

:   

Changes or modifications not expressly approved by Microhard Systems Inc. could void the user’s authority to operate the equipment. 
This device has been tested with UFL connectors with the antennas listed in Appendix A When integrated in OEM products, fixed 
antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed in the tables 
must be tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions).  Please Contact 
Microhard Systems Inc. if you need more information. 
 
Innovation, Science and Economic Development Canada: This device has been designed to operate with the antennas listed above, and 
having a maximum gain of 14 dBi. Antennas not included in this list or having a gain greater than 14 dBi 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 (EIRP) is not more than that required for 
successful communication.  This Class B digital apparatus complies with Canadian ICES-003.
