Report No.: AGC15733260102FR01 Page 43 of 50 12.3 Measurement Procedure According to TIA/EIA-603 2.2.19 requirement, as for the product different from PTT, we use test steps as follows: 1. Connect DUT into Test discriminator and Storage Oscilloscope and keep DUT stats ON; 2. Input 1kHz signal into DUT; 3. Set the modulation domain analyzer to trigger on the rising edge of the waveform in order to capture a 4. single-shot turn-on of the transmitter signals; 5. Keep DUT in OFF state and Key the PTT; 6. Observe the stored oscilloscope of modulation domain analyzer. The signal trace shall be maintained within the allowable limits during the periods t1 and t2,and shall also remain within limits following t2; 7. Adjust the modulation domain analyzer to trigger on the falling edge of the transmitter waveform in order to capture a single-shot turn-off transmitter of the transmitter signal. 8. Keep the digital portable radio in ON state and unkey the PTT; 9. Observe the stored oscilloscope of modulation domain analyzer, The signal trace shall be maintained within the allowable limits during the period t3. 10. Set the signal generator to the assigned transmitter frequency and modulate it with a 1 kHz tone at ±12.5 kHz deviation and set its output level to -100dBm. 11. Turn on the transmitter. 12. Supply sufficient attenuation via the RF attenuator to provide an input level to the stored oscilloscope that is 40 dB below the maximum allowed input power when the transmitter is operating at its rated power 13. level. Note this power level on the stored oscilloscope as P0. 14. Turn off the transmitter. 15. Adjust the RF level of the signal generator to provide RF power equal to P0. This signal generator RF level shall be maintained throughout the rest of the measurement. 16. Remove the attenuation, so the input power to the stored oscilloscope is increased by 30 dB when the transmitter is turned on. 17. Adjust the vertical amplitude control of the stored oscilloscope to display the 1000 Hz at ±4 divisions vertically centered on the display. Set trigger mode of the Spectrum Analyzer to “Video”, and tune the “trigger level” on suitable level. Then set the “tiger offset” to -10ms for turn on and -15ms for turn off. 18. Turn on the transmitter and the transient wave will be captured on the screen of Spectrum Analyzer. 19. Observe the stored display. The instant when the 1 kHz test signal is completely suppressed is considered to be ton. The trace should be maintained within the allowed divisions during the period t1 and t2. 20. Then turn off the transmitter, and another transient wave will be captured on the screen of Spectrum Analyzer. The trace should be maintained within the allowed divisions during the period t3. Report No.: AGC15733260102FR01 Page 44 of 50  Describe limit line of transmitter frequency behavior:  ton: The switch-on instant ton of a transmitter is defined by the condition when the output power, measured at the antenna terminal, exceeds 0,1 % of the full output power (-30 dBc).  t1: period of time starting at ton and finishing according to above 11.1  t2: period of time starting at the end of t1 and finishing according to above 11.1  toff: switch-off instant defined by the condition when the output power falls below 0,1 % of the full output power (-30 dBc).  t3: period of time that finishing at toff and starting according to above 11.1 Report No.: AGC15733260102FR01 Page 45 of 50 12.4 Measurement Result 12.5 kHz Channel Separation, Analog modulation, Assigned Frequency:406.125MHz-Turn On 12.5 kHz Channel Separation, Analog modulation, Assigned Frequency:406.125MHz-Turn Off Note: All the test frequencies was tested, but only the worst data be recorded in this part.

This equipment meets the requirements of the FCC Rules, Parts 90.203(e) and (g), as applicable. Programming of this product 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 SkyConnex Communications Limited 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 60ms of normal bursts are sent in alternate 30ms 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).
