                          SUBJECT:               ITRONIX CORPORATION
                                                 FCC ID: KBCIX100XAC860
                                                 Part 24(E) - Certification
                                                 Limited Modular Approval

On behalf of Itronix Corporation is a Limited Modular Approval application for Part 24(E) Certification of the AirCard 860 Dual-Band
GSM/GPRS/EDGE/UMTS PCMCIA Modem (manufactured by Sierra Wireless, Inc.) installed in the Itronix Corporation IX100X Series
Rugged Handheld PC utilizing a permanently attached external Nearson ¼-Wave Helix antenna and a MaxRad vehicle-mount antenna with
Itronix vehicle cradle. The AirCard 860 Dual-Band GSM/GPRS/EDGE/UMTS PCMCIA Modem is installed in the IX100X by Itronix
Corporation prior to shipment and is not intended for installation or reconfiguration by the end user. The AirCard 860 is a quad-band
modem and Itronix Corporation will ensure that the non-authorized bands are not available to the end user.

The AirCard 860 Dual-Band GSM/GPRS/EDGE/UMTS PCMCIA Modem can also be co-located in the IX100X Handheld PC with an
optional 802.11bg/Bluetooth Combo Module Model: WM-BR-MR-01 (manufactured by Universal Scientific Industrial Co., Ltd.). A separate
Limited Modular Approval Composite Certification application for the WM-BR-MR-01 is submitted simultaneously with this application (FCC
ID: KBCIX100XUSI-WLBT). The WM-BR-MR-01 is also installed in the IX100X by Itronix Corporation prior to shipment and is not intended
for installation or reconfiguration by the end user. The IX100X Handheld PC can be configured by Itronix Corporation to contain either one
of the internal radios described above or both. It is the intention and purpose of the two referenced Limited Modular Approval applications
that all three IX100X host PC configuration options will be approved for certification within these submittals. Depending on the transmitter
configuration(s) installed, Itronix Corporation will label the IX100X host PC accordingly with the appropriate FCC ID label(s) applicable for
the specific configuration(s).

The co-transmit operations when both transmitters are installed are the AirCard 860 and Bluetooth only. The AirCard 860 and 802.11bg do
not co-transmit (please refer to the applicant’s attestation letter). Radiated spurious emissions measurements were evaluated for co-
transmit operation of the AirCard 860 and Bluetooth and were found to be in compliance.
