Qixiang Electron Science & Technology Co., Ltd. attests that the Digital DMR and Analog UHF Two Way Radio will not be marketed to USA users with the frequency band which is not allowed by the rule part 90. Per the FCC’s KDB634817 guidance, as an alternative to listing the exact frequencies, we acknowledge that it’s a violation of the FCC Rules if this device operates on unauthorized frequencies. Also, equipment programming is the responsibility of Authorized Service Personnel, the Digital DMR and Analog UHF Two Way Radio is complies with 47 CFR Part 90.203(e), in that the operator cannot directly program the transmit frequencies using the normally accessible external controls. Please contact me if you require any additional information.

Qixiang Electron Science & Technology Co., Ltd. Qixiang Building, Tangxi Industrial Zone, Luojiang, Quanzhou, Fujian, 362011 China Date: 2023-03-30 FCC Part 90 Letter FEDERAL COMMUNICATIONS COMMISSION Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: FCC ID: T4K-D278U Dear Sir/Madam, We, Qixiang Electron Science & Technology Co., Ltd., acknowledge that this device will not be marketed to USA users with the frequency band which is not allowed by rule part 90.and it is a violation of FCC rules if this device is operated on unauthorized frequencies inside the U.S.A. This equipment meets the requirements of the FCC Rules, Parts 90.203(e) and (g), as applicable. Programming of this products transmit frequencies can be performed ONLY by the manufacturer or by service or by maintenance personal. The operator can’t program transmit frequencies using the equipment’s external operation controls. This is to certify that the requirements of 47 CFR Part 90.203(j)(4) and (5) spectrum efficiency are met by the Qixiang Electron Science & Technology Co., Ltd. demonstrated by the tests conducted on the sample radio provided. The tests show that the 4FSK data rate is in accordance with ETSI TS 102 361-1, that is 9600 bits per second in a 12.5 kHz bandwidth to satisfy the data rate requirement of 4800 bits per second per 6.25 kHz of channel bandwidth (7K60F1D emissions). Additionally the radio uses the AMBE+2 half-rate vocoder to compress 60 ms of normal bursts are sent in alternate 30 ms TDMA slots and so comply with the equivalence of one voice channel per 6.25 kHz bandwidth (7K60F1W emission). Additionally the radio also meets the requirement of one voice channel per 12.5 kHz of channel bandwidth for analogue speech (11k0F3E emission).

Configure the EUT as shown in figure 1, adjust the audio input for 60% of rated system deviation at 1kHz using this level as a reference (0dB) and vary the input level from –20 to +20dB. Record the frequency deviation obtained as a function of the input level. (2). Repeat step 1 with input frequency changing to 300, 1000, 1500 and 3000Hz in sequence. 9.2.2 Audio Frequency Response (1). Configure the EUT as shown in figure 1. (2). Adjust the audio input for 20% of rated system deviation at 1 kHz using this level as a reference (0 dB). (3). Vary the Audio frequency from 100 Hz to 10 kHz and record the frequency deviation. (4). Audio Frequency Response = 20log10 (Deviation of test frequency/Deviation of 1 kHz reference). 9.3 MEASUREMENT SETUP Report No.: AGC01284221006FE10 Page 39 of 60 9.4 MEASUREMENT RESULTS (A).

MAXIMUMN TRANSMITTER POWER 10.1 PROVISIONS APPLICABLE Per FCC §2.1046. § 90.205: Maximum ERP is dependent upon the station’s antenna HAAT and required service area. 10.2 MEASUREMENT METHOD The RF output of Two-way Radio was conducted to a spectrum analyzer through an appropriate attenuator. In the semi-anechoic chamber, setup as illustrated above the DUT placed on the 0.8m height of Turn Table, rotated the table 45 degree each interval to search the maximum radiation power and receiver antenna shall be rotated vertical and horizontal polarization and moved height from 1m to 4m to find the maximum polar radiated power for each degree interval. The “Read Value” is the spectrum reading of maximum power value. The substitution antenna is substituted for DUT at the same position and signals generator (S.G) export the CW signal to the substitution antenna via a TX cable. The receiver antenna shall be rotated vertical and horizontal polarization and moved height from 1m to 4m to find the maximum radiation power. Record the power level of maximum radiation power from spectrum. So, the Measured substitution value = Ref level of S.G + TX cables loss – Substituted Antenna Gain. EIRP = “Read Value” + Measured substitution value + 2.15. 10.3 MEASUREMENT METHOD Conducted Output Power: Report No.: AGC01284221006FE10 Page 42 of 60 Effective Radiated Power: Radiated Below 1GHz Radiated Above 1 GHz Report No.: AGC01284221006FE10 Page 43 of 60 10.4 MEASUREMENT RESULTS Conducted Power Measurement Results Mode Channel Separati…
