                                                Part 24(E) - Certification
                                                Composite Application (PCB)


On behalf of Itronix Corporation is an application for Part 24(E) Certification of Model: IX325-AC775BT Rugged Tablet PC with internal
Dual-Band PCS/Cellular GSM GPRS/EDGE PCMCIA Modem Model: AirCard 775 manufactured by Sierra Wireless, Inc. utilizing an
external monopole antenna attached to the modem card. The DUT also incorporates an internal MSI MS-6837 Bluetooth Transmitter with
internal PIFA antenna installed in the left hand section of the DUT. The Part 15(C) certification application for the MSI MS-6837 Bluetooth
portion of the DUT is submitted simultaneously with this application under the same FCC ID: KBCIX325-AC775BT. The Sierra Wireless
AirCard 775 Dual-Band GSM GPRS/EDGE PCMCIA Modem can transmit simultaneously with the MSI MS-6837 Bluetooth. Please
refer to the Co-Transmit Supplementary EMC test report submitted within this application for co-located simultaneous transmit
measurement data.
