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 MMCX 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.
Industry Canada: This device has been designed to operate with the antennas listed below, and having a maximum gain
of 14.2 dBi. Antennas not included in this list or having a gain greater than 14.2 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.
