The applicant has been cautioned as to the following 15.21 - Information to User The user’s manual or instruction manual for an intentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 15.27(a) - Special Accessories Equipment marked to a consumer must be capable of complying with the necessary regulations in the configuration in which the equipment is marketed. Where special accessories, such as shielded cables and/or special connectors are required to enable an unintentional or intentional radiator to comply with the emission limits in this part, the equipment must be marketed with, i.e. shipped and sold with, those special accessories. However, in lieu of shipping or packaging the special accessories with the unintentional or intentional radiator, the responsible party may employ other methods of ensuring that the special accessories are provided to the consumer without an additional charge. Information detailing any alternative method used to supply the special accessories for a grant of equipment authorization or retained in the verification records, as appropriate. The party responsible for the equipment, as detailed in § 2.909 of this chapter, shall ensure that these special accessories are provided with the equipment. The instruction manual for such devices shall include appropriate instructions on the first page of text concerned with the installation of the device that these special accessories must be used with the device. It is the responsibility of the user to use the needed special accessories supplied with the equipment. p1830001_FCC_Part 15.247_Rev 3.0 Page 5 of 20

Standard Test Conditions Engineering Practices Except as noted herein, the following conditions and procedures were observed during the testing: In accordance with ANSI C63.10-2013 and unless otherwise indicated in the specific measurement results, the ambient temperature of the actual EUT was maintained within the range of 10° to 40°C (50° to 104°F) unless the particular equipment requirements specified testing over a different temperature range. Also, unless otherwise indicated, the humidity levels were in the range of 10% to 90% relative humidity. Measurement results, unless otherwise noted, are worst-case measurements. Environmental Conditions Temperature Humidity Pressure (ºC) (%) (mbar) 23.3 28.9 967 EUT Description Model: DD-005 Description: Battery Powered, wireless positioning and duress alarm for prison guards Firmware: N/A Software: N/A Serial Number: N/A Additional Information: Unit is incorporating a proprietary protocol, based off Bluetooth Low Energy technology, with frequency range of 2402- 2480 MHz. For Conducted testing an unassembled device with RF connector was utilized and it was powered up with DC power supply of 6.0 V. The regular radiated emissions test device work with batteries p1830001_FCC_Part 15.247_Rev 3.0 Page 6 of 20

EUT Operation during Tests The unit begins transmitting by power up at 400 uSec bursts of random data on Channel 37(2402), 38(2426) and 39(2480) at approximately 2.5m Sec intervals for 0 dBm and 4 dBm. The +25 dBm timing is slightly different from +0 and +4 dBm. At +25 dBm, the transmissions are 400 uSec long, but they occur every 6.5 mSec. Duty Cycle for both 25 dBm and 0 dBm modes are as below: Duty Cycle Calculation The production sample of Model DD-005 transmits once every second on 3 channels, with each transmission taking 184µsec, or 0.000184 seconds. Total transmission time, on each channel, per second is 184µsec or 0.000184 seconds. This results in a duty cycle of 0.0184%. Duty Cycle Correction = 10Log(1/DC) Where DC is the Duty Cycle Duty Cycle Correction = 10Log(1/0.000184) Duty Cycle Correction = 37.35 dB p1830001_FCC_Part 15.247_Rev 3.0 Page 7 of 20

Radiated Spurious Emissions Engineer: Poona Saber Test Date: 3/9/2018 Test Procedure Radiated Spurious Emissions: 30 – 1000 MHz The EUT was setup in a semi-anechoic test chamber set 3m from the receiving antenna. The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. A spectrum analyzer was used to verify that the EUT met the requirements for Radiated Emissions. The EUT was tested by rotating it 360 with the antennas in both the vertical and horizontal orientation and was raised from 1 to 4 meters to ensure the TX signal levels were maximized. All emissions from 30 MHz to 1 GHz were examined. Measured Level includes antenna and receiver cable correction factors. Correction factors were input into the spectrum analyzer before recording “Measured Level”. RBW = 100 KHz VBW = 300 KHz Detector – Quasi Peak Test Setup EUT Antenna Spectrum Analyzer Test Procedure for Radiated Spurious Emissions above 1 GHz The EUT was setup in a semi-anechoic test chamber set 3m from the receiving antenna. The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. A spectrum analyzer was used to verify that the EUT met the requirements for Radiated Emissions. The EUT was tested by rotating it 360 with the antennas in both the vertical and horizontal orientation and was raised from 1 to 4 meters to ensure the TX signal levels were maximized.

Conducted Spurious Emissions 15.247 (d) Engineer: Poona Saber Test Date: 3/9/2018 Test Procedure The EUT was connected directly to a spectrum analyzer. The Spectrum Analyzer was set to the following: RBW = 100 kHz VBW ≥ 3 x RBW Peak Detector Trace mode = max hold Sweep = auto couple Frequency Range = 30MHz – 10th Harmonic of the fundamental The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. The trace was allowed to stabilize. All emission were investigated to insure they were attenuated from the peak fundamental by at least 20dB. If the average power levels were measured then the out-of-band emissions needed to be attenuated by 30dB. In addition emissions were investigated at the band edges to insure all out-of-band emissions were attenuated 20 or 30dB as necessary. Test Setup EUT Spectrum Analyzer See Annex B for Test Data p1830001_FCC_Part 15.247_Rev 3.0 Page 12 of 20

DTS Bandwidth Engineer: Poona Saber Test Date: 3/8/2018 Test Procedure The EUT was connected directly to a spectrum analyzer. The Spectrum Analyzer was set to the following: RBW = 100 kHz VBW ≥ 3 x RBW Peak Detector Trace mode = max hold Sweep = auto couple Span = 1.5 x EBW The EUT was set to transmit at the lowest, middle and highest channels of the band at the maximum power levels. The maximum width of the emission that was determined by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that were attenuated by 6db and this value was used to determine the width of the carrier. Alternatively the spectrum analyzer’s automatic bandwidth capability was used.

Transmitter Power Spectral Density (PSD) Engineer: Kenneth Lee Test Date: 3/26/2018 Test Procedure The EUT was connected directly to a spectrum analyzer. The Spectrum Analyzer was set to the following: Set analyzer center Frequency to DTS channel center frequency Set RBW to: 3 kHz ≤ RBW ≤ 100 KHz VBW ≥ 3 x RBW Sweep time = auto couple. Detector = peak. Trace mode = max hold The EUT was set to transmit at the lowest, middle and highest channels of the band at the maximum power levels. Once the trace has stabilize the peak marker was used to determine the peak power spectral density.
