The maximum permitted unwanted emission level is 20 dB below the maximum permitted fundamental level. For that the EUT use fundamental frequency of 433.92MHz, after calculation, the limit is: Fundamental limit = 41.6667 * 433.92 - 7083.3333 = 10996.68uV/m =80.83 dBuV/m Spurious limit = 80.83 – 20 = 60.83dBuV/m //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// The radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a) showed as below: Frequency Field Strength Measurement Distance (MHz) (dBuV/m) (m) __________________________________________________________ 30 - 88 40.0 3 88 - 216 43.5 3 216 - 960 46.0 3 Above 960 54.0 3 __________________________________________________________ FCC ID: VYY-DC908B TTRF15.231_V1 © 2015 Intertek

Test report no.160503105SHA-001 Page 10 of 23 3.2 Test Configuration EUT Antenna mast Turn Table Test receiver 3.3 Test procedure and test setup The measurement was applied in a semi-anechoic chamber. While testing for spurious emission higher than 1GHz, the pre-amplifier and high pass filter is equipped just at the output terminal of the antenna. Tabletop devices shall be placed on a nonconducting platform with nominal top surface dimensions 1 m by 1.5 m. For emissions testing at or below 1 GHz, the table height shall be 80 cm above the reference ground plane. For emission measurements above 1 GHz, the table height shall be 1.5 m. The turntable rotated 360 degrees to determine the position of the maximum emission level. The EUT was set 3 meters away from the receiving antenna which was mounted on an antenna mast. The antenna moved up and down between from 1meter to 4 meters to find out the maximum emission level. Both horizontal and vertical polarities of the receiving antenna were assessed and the higher reading was listed in this report. The radiated emission was measured using the test receiver with the resolutions bandwidth set as: RBW=300 Hz, VBW=1 kHz (9 kHz~150 kHz); RBW=10 kHz, VBW=30 kHz (150 kHz~30MHz); RBW = 100 kHz, VBW = 300 kHz (30MHz~1GHz) RBW = 1MHz, VBW = 3MHz (>1GHz for PK); FCC ID: VYY-DC908B TTRF15.231_V1 © 2015 Intertek

Corrected Reading = Original Receiver Reading + Correct Factor 3. Margin = Limit - Corrected Reading 4. If PK Corrected reading is less than AV limit, the AV test can be elided. Example: Assuming Antenna Factor = 30.20dB, Cable Loss = 2.00dB, Gain of Preamplifier = 32.00dB, Original Receiver Reading = 10.00dBuV/m, limit = 40.00dBuV/m. Then Correct Factor = 30.20 + 2.00 – 32.00 = 0.20dB; Corrected Reading = 10dBuV + 0.20dB = 10.20dBuV/m; Margin = 40.00dBuV/m – 10.20dBuV/m = 29.80dB. FCC ID: VYY-DC908B TTRF15.231_V1 © 2015 Intertek

(2) A transmitter activated automatically shall cease transmission within 5 seconds after activation. (3) Periodic transmissions at regular predetermined intervals are not permitted. However, polling or supervision transmissions, including data, to determine system integrity of transmitters used in security or safety applications are allowed if the total duration of transmissions does not exceed more than two seconds per hour for each transmitter. There is no limit on the number of individual transmissions, provided the total transmission time does not exceed two seconds per hour. (4) Intentional radiators which are employed for radio control purposes during emergencies involving fire, security, and safety of life, when activated to signal an alarm, may operate during the pendency of the alarm condition. (5) Transmission of set-up information for security systems may exceed the transmission duration limits in (1) and (2) above, provided such transmission are under the control of a professional installer and do not exceed ten seconds after a manually operated switch is released or a transmitter is activated automatically. Such set-up information may include data. FCC ID: VYY-DC908B TTRF15.231_V1 © 2015 Intertek

The central frequency of test receiver was set as the operating frequency of EUT and the Span was set as 0. The EUT was switched once. The test receiver recorded the whole time from the triggered moment to the time of stopping radiating. For manual switching, to avoid uncertainty, the operating above would be repeated five times and the worst data is recorded. 4.4 Test protocol Temperature : 22 C Relative Humidity : 54 % Whole time from the triggered moment to the time of stopping radiating: 0.520s. As a result, the EUT complies with the limit of 5s’ deactivating time. FCC ID: VYY-DC908B TTRF15.231_V1 © 2015 Intertek

For devices operating above 900MHz, the emission shall be no wider than 0.5% of the center frequency. Bandwidth is determined at the points 20dB down from the modulated carrier. The limit for the EUT = 0.25% * 433.92MHz = 1084.8kHz 5.2 Test Configuration EUT Antenna mast Turn Table Test receiver 5.3 *Test procedure and test setup The EUT and simulators were placed on a 0.8m high wooden turntable above the horizontal metal ground plane. The turn table rotated 360 degrees to determine the position of the maximum emission level. The EUT was set 3 meters away from the receiving antenna which was mounted on an antenna mast. The antenna moved up and down between from 1meter to 4 meters to find out the maximum emission level. The central frequency of test receiver was set near the operating frequency of EUT. The test was conducted using the Spectrum Analyzer with the resolutions bandwidth set below: RBW = approximately 1% of the emission bandwidth. VBW > RBW.
