Digital Two Way Radio SkyConnex Communications Limited Instruction Manual 2 Attention Please read this instruction manual carefully before use. Please keep this manual, which contains important instructions on the use of Digital Trunking portable radio series. △ ! Battery Usage Precautions.  Do not disassemble or modify the battery. Batteries have internal protective circuitry, and disassembly or modification of the battery may cause damage to the protective circuitry, and the battery may smoke, rupture, or catch fire.  Do not short-circuit the battery. Do not use any metal to connect the "+" and "-" terminals of the battery, and do not place or store the battery in a container with a metal object. If the battery is short-circuited, excessive current will be drawn, and the battery will heat up, smoke, rupture, or catch fire.  Do not place the battery near a fire, furnace or other heater, and do not burn or heat the battery. Batteries may generate heat, smolder, rupture, or catch fire.  Do not expose the battery to rain, snow, seawater or any other liquids. Do not charge or use wet batteries. If the battery gets wet, be sure to dry it before use. △ ! Charger usage precautions.  Do not block the air vents of the charger, as this may cause damage to the internal parts and result in electric shock or disaster.  Do not allow the charger to get close to heat sinks or heat sources; do not put paper under the charger.  Do not place the charger in a closed container or on a bed, sofa or carpet.  Do not use the charger near bathtubs, pools, swimming pools or in wet basements.  Do not place metal sheets in the card holder, as these conductive materials may damage the unit.  Do not press the power supply strongly enough to bend or distort the pins.  Do not leave the charger exposed to dirt, dust, water or food.  Do not expose the charger to high temperatures or sunlight. 3 Content 1.

Maximum Transmitter Power 10.1 Provisions Applicable Per FCC §2.1046 and §90.205: Maximum ERP is dependent upon the station’s antenna HAAT and required service area. 10.2 Measurement Procedure 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 Setup Conducted Output Power: Report No.: AGC15733260101FR01 Page 41 of 60 Effective Radiated Power: Radiated Below 1GHz Radiated Above 1 GHz Report No.: AGC15733260101FR01 Page 42 of 60 10.4 Measurement Result Conducted Power Measurement Results Mode Channel Separation Test Channel Measurement Result (dBm) For 30.00dBm(1W) Analog +Voice 12.5 kHz Bottom(406.125MHz) 29.94 Middle(453.2125MHz) 29.78 Middle (458.2125MHz) 29.66 Top (469.975MHz) 29.77 Digital (Voice+Data) 12.5 kHz Bottom(406.125MHz) 29.94 Middle(453.2125MHz) 29.66 Middle (458.2125MHz) 29.53 Top (469.975MHz) 29.73 Conducted Power Measurement Results Mode Channel Separation Test Channel Measurement Result (dBm) For 36.02dBm(4W) Analog +Voice 12.5 kHz Bottom(406.125MHz) 35.73 Middle(453.2125MHz) 35.92 Middle (458.2125MHz) 35.91 Top (469.975MHz) 35.94 Digital (Voice+Data) 12.5 kHz Bottom(406.125MHz) 35.76 Middle(453.2125MHz) 35.80 Middle (458.2125MHz) 35.82 Top (469.975MHz) 35.91 Report No.: AGC15733260101FR01 Page 43 of 60 Radiated Power Measurement Results-1W Test Mode Frequency (MHz) Reading Level (dBuv/m) Antenna Polarization S.G.

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 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).
