Ref. No.: LR500110608C 3.2.3 20 dB Bandwidth Procedure: The bandwidth at 20 dB below the highest inband spectral density was measured with a spectrum analyzer connected to the antenna terminal, while EUT had its hopping function disabled at the highest, middle and the lowest available channels.. After the trace being stable, Use the marker-to-peak function to set the marker to the peak of the emission. Use the marker-delta function to measure 20dB down one side of the emission. Reset the marker-delta function, and move the marker to the other side of the emission, until it is ( as close as possible to ) even with the reference marker level. The marker-delta reading at this point is the 20 dB bandwidth of the emission. The spectrum analyzer is set to: Center frequency = the highest, middle and the lowest channels Span = 2 MHz (approximately 2 or 3 times of the 20 dB bandwidth) RBW = 30 kHz Sweep = auto VBW = 30 kHz (VBW ≥ RBW) Detector function = peak Trace = max hold Measurement Data: Frequency Test Results Channel No. (MHz) Measured Bandwidth (MHz) Result 2441 39 0.935 Complies - See next pages for actual measured spectrum plots.

Ref. No.: LR500110608C 3.2.7 Field Strength of Harmonics Procedure: The EUT was placed on a 0.8m high wooden table inside a shielded enclosure. An antenna was placed near the EUT and measurements of frequencies and amplitudes of field strengths were recorded for reference during final measurements. For final radiated testing, measurements were performed in OATS. Measurements were performed with the EUT oriented in 3 orthogonal axis and rotated 360 degrees to determine worst-case orientation for maximum emissions. The spectrum analyzer is set to: Center frequency = the worst channel Frequency Range = 30 MHz ~ 10th harmonic.

However, operation within these frequency bands is permitted under other sections of this Part, e.g. 15.231 and 15.241. Copyright ○ c 2006, LTA Co., Ltd. Page 26 of 31

Ref. No.: LR500110608C 3.2.8 AC Conducted Emissions Procedure: The conducted emissions are measured in the shielded room with a spectrum analyzer in peak hold. While the measurement, EUT had its hopping function disabled at the middle channels in line with Section 15.31(m). Emissions closest to the limit are measured in the quasi-peak mode (QP) with the tuned receiver using a bandwidth of 9 kHz. The emissions are maximized further by cable manipulation and Exerciser operation. The highest emissions relative to the limit are listed. Measurement Data: Complies - See next pages for actual measured spectrum plots. - No emissions were detected at a level greater than 10dB below limit.
