1.2    Test Location and Equipment Used
Test Location The EUT was fully tested at Willow Run Test Labs, LLC, 8501 Beck Road, Building 2227,
Belleville, MI 48111 USA. The Open Area Test Site (OATS) description and attenuation characteristics are on
file with the FCC Laboratory, Columbia, Maryland (FCC Reg. No: 688478) and with Industry Canada, Ottawa,
ON (File Ref. No: IC 8719A-1).

Test Equipment Pertinent test equipment used for measurements at this facility is listed in Table 1. The quality
system employed at Willow Run Test Labs, LLC has been established to ensure all equipment has a clearly identifiable
classification, calibration expiry date, and that all calibrations are traceable to the SI through NIST, other recognized
national laboratories, accepted fundamental or natural physical constants, ratio type of calibration, or by comparison
to consensus standards.

2.1.1    EUT Configuration
The EUT is configured for testing as depicted in Figure 2.

2.1.2    Modes of Operation
The EUT is capable of three key modes of operation. Upon manually activated LF interrogation (through the use of
special LF tool at a vehicle dealership), the EUT responds with a singe transmission containing a number of frames
used to configure the device with the vehicle. When the EUT is placed in the vehicle tire and the vehicle drives, it
can, in the worst case, periodically transmit a set of data frames approximately once every 30 seconds. In the case of
an emergency condition, the EUT will transmit tire pressure and temperature information throughout the duration
of the condition.

2.1.6    Modifications Made
There were no modifications made to the EUT by this laboratory.

2.1.7    Production Intent
The EUT appears to be a production ready sample.

2.1.8    Declared Exemptions and Additional Product Notes
The EUT is permanently installed in a transportation vehicle. As such, digital emissions are exempt from US and
Canadian digital emissions regulations (per FCC 15.103(a) and IC correspondence on ICES-003).
   The EUT also employs some modes of operation that alert the vehicle user of sudden changes in tire pressure.
Such alert modes fall under FCC 15.231(a)(4), and may operate during the pendency of the alarm condition. A
detailed list of all operating modes is included in the Description of Operation exhibit included in this application.

3      Emissions
3.1     General Test Procedures
3.1.1     Radiated Test Setup and Procedures
Radiated electromagnetic emissions from the EUT are first evaluated in our shielded fully anechoic chamber. Spec-
trum and modulation characteristics of all emissions are recorded, and emissions above 1 GHz are fully characterized.
The anechoic chamber contains a set-up similar to that of our outdoor 3-meter site, with a turntable and antenna
mast. Instrumentation, including spectrum analyzers and other test equipment as detailed in Section 1.2 are em-
ployed. After indoor pre-scans, emission measurements up to 1 GHz are made on our outdoor 3-meter Open Area
Test Site (OATS). If the EUT connects to auxiliary equipment and is table or floor standing, the configurations
prescribed in ANSI C63.4 / CISPR 22 are followed. Alternatively, a layout closest to normal use (as declared by the
provider) is employed if the resulting emissions appear to be worst-case in such a configuration. See Figure 3.

                                                Radiated Emissions Table

                                   Figure 3: Radiated Emissions Diagram of the EUT.

All intentionally radiating elements are placed on the test table lying flat, on their side, and on their end (3-axes)
and the resulting worst case emissions are recorded. For both horizontal and vertical polarizations, the test antenna
is raised and lowered from 1 to 4 m in height until a maximum emission level is detected. The EUT is then rotated
through 360o in azimuth until the highest emission is detected. The test antenna is then raised and lowered one last
time from 1 to 4 m and the worst case value is recorded.
    If the EUT exhibits spurious emissions due to internal receiver circuitry, such emissions are measured with an
appropriate carrier signal applied. For devices with intentional emissions below 30 MHz, a shielded loop antenna
is used as the test antenna. It is placed at a 1 meter receive height and appropriate low frequency magnetic field
extrapolation to the regulatory limit distance is employed. Emissions between 30 MHz and 1 GHz are measured
using tuned dipoles and/or calibrated broadband antennas. Emissions above 1 GHz are characterized using standard
gain horn antennas. Care is taken to ensure that test receiver resolution and video bandwidths meet the regulatory
requirements, and that the emission bandwidth of the EUT is not reduced.

      Photographs of the test setup employed are depicted in Figure 4.

3.1.2    Conducted Test Setup and Procedures
Battery Power Conducted Spurious The EUT is not subject to power line conducted emissions measurements
when it is powered solely by its internal battery.

3.1.3    Power Supply Variation
Tests at extreme supply voltages are made if required by the the procedures specified in the test standard, and results
of this testing are detailed in this report.


DC Extreme Voltages If the EUT is designed for operation from a lead-acid battery power source, the extreme
test voltages are evaluated between 90% and 130% of the nominal battery voltage declared by the manufacturer. For
float charge applications using gel-cell type batteries, extreme test voltages are evaluated between 85% and 115%
of the nominal battery voltage declared. For all battery operated equipment, worst case intentional and spurious
emissions are re-checked employing a new (fully charged) battery.

3.1.4    Thermal Variation
Tests at extreme temperatures are made if required by the procedures specified in the test standard, and results of
this testing are detailed in this report. The provider has declared that the EUT is designed for operation over the
temperature range −40o C to +85o C. Before any temperature measurements are made, the equipment is allowed to
reach a thermal balance in the test chamber, temperature and humidity are recorded, and thermal balance is verified
via a thermocouple based probe.

3.2.2    Fundamental Emission Bandwidth
Emission bandwidth (EBW) of the EUT is measured with the device placed in the test mode(s) with the shortest
available frame length and minimum frame spacing. Radiated emissions are recorded following the test procedures
listed in Section 1.1. The 20 dB EBW is measured as the max-held peak-detected signal when the IF bandwidth
is greater than or equal to 1% of the receiver span. For complex modulations other than ASK and FSK, the 99%
emission bandwidth per IC test procedures has a different result, and is also separately reported.The results of EBW
testing are summarized in Table 4. Plots showing measurements employed to obtain the emission bandwidth reported
are provided in Figure 6.

3.2.3    Fundamental Emission
Following the test procedures listed in Section 1.1, radiated emissions measurements are made on the EUT for both
Horizontal and Vertical polarized fields. Table 5 details the results of these measurements.
