| Output Power listed is conducted. Limited Modular Approval. This module only can be installed with the 3 hosts: MPU5 Dismount Kit (WR-5100), Aircraft Kit (WR-AIR-SYS-1-02) and S-Band Integrated Sector Antenna (WR-INT-ANT-SYS-01), therefore is limited. This module is intended to be used only in the grantee equipment and is not for sale to the public or OEMs other than the grantee. This module is limited, requiring the Grantee to file a Class II permissive change for each specific host per the test plan defined in the module integration instructions. This device may be used in both mobile and portable applications. The antenna(s) used for this transmitter must not be used except in accordance with FCC multi-transmitter product procedures. Only those antenna(s) tested with the device or similar antenna(s) with equal or lesser gain may be used with this transmitter. In portable configuration, the antennas used for this transmitter as shown in this filing must be installed to provide a separation distance of at least 5 cm from all persons. The highest reported SAR for Body-worn and simultaneous transmission exposure conditions are 0.55W/kg, 1.54W/kg respectively. |
