The tests documented in this report were performed in accordance with MP-5, and FCC CFR PART
18.

2.1 EUT Configuration
The EUT configuration for testing is installed on RF field strength measurement to meet the
Commissions requirement and operating in a manner that intends to maximize its emission
characteristics in a continuous normal application.

2.2 EUT Exercise
The EUT was operated in the charging and compunction mode to fix the TX frequency that was for the
purpose of the measurements.
According to its specifications, the EUT must comply with the requirements of the Section 18.305 and
18.307 under the FCC Rules Part 18.

2.3 General Test Procedures

2.3.1 Conducted Emissions
The EUT is placed on the turntable, which is 0.8 m above ground plane. According to the requirements
in FCC MP-5 for Conducted emissions from the EUT measured in the frequency range between 0.15
MHz and 30MHz using Quasi-peak and average detector modes.

2.3.2 Radiated Emissions
The EUT is placed on a turn table, which is 0.8 m above ground plane. The turntable shall rotate 360
degrees to determine the position of maximum emission level. EUT is set 3m away from the receiving
antenna, which varied from 1m to 4m to find out the highest emission. And also, each emission was to
be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order
to find out the maximum emissions, exploratory radiated emission measurements were made
according to the requirements in FCC MP-5 for radiated emission.
