The T6400 radio will not be user programmable. The RF power output level of the T6400 radio will be electronically tuned in the factory and cannot be adjusted by any other means. The associated tune value is stored in a radio internal memory location (code plug). The radio will be tuned as follows: For FRS operation, the automated test system first measures the conducted RF output power on FRS channel 11 (Freq = 467.6375 MHz) and at 4.5VDC +/- .005VDC. If the power is within the tune window of 500 to 550mW a default code plug value is used. If the power measured is higher than 550mW the test system reduces the default codeplug value until the power is within the tune target. If the power measured is lower than the 500mW, FCC ID: AZ489FT4850 the test system increases the default code plug value until the power is within the tune target. This new code plug value will now become the default power setting for this particular radio and used on the FRS specific frequencies on channels 8 to 14. Modification to the radio codeplug is not possible without access to Motorola proprietary information of the codeplug bitmap, programming software, and hardware, which are for Motorola internal use only at the manufacturing facilities. For the GMRS frequencies, the conducted RF output power is controlled to 1.0 Watt by Motorola proprietary software developed specifically for this family of radios. The automated test system selects a GMRS channel and the radio software sets the power control voltage on the RF power amplifier (PA) to it’s maximum setting. The RF PA is limited to 1.0-Watt maximum conducted power by the performance capabilities of the final stage device and it’s topology. The factory measures the RF power on GMRS channel 4 (Freq = 462.6375 MHz) to assure 1.0 Watt is obtained. Once the radio is prope…

The conducted power measurements converted to dBm minus the antenna loss, Which is 2.4dB (see exhibit 6A-2) and converted back to watts ERP Example: GMRS conducted RF output = 1.04 Watts 10log(1.0w/1w) =30.17dBm ERP = 30.17dBm-2.4dB=27.77dBm ERP = 10^(27.77/10)= 10^2.777 = 599 mWatts. The antenna gain (loss) is measured in an anechoic chamber free of outside radiation, refraction, defraction and interference. The anechoic chamber’s path loss = 37.9 dBm. The antenna was placed on an infinite ground plane, and 10dBm was transmitted from the antenna. The receiving spectrum analyzer registered –30.3 dBm. Therefore, the antenna gain = Pr – Pt + Path loss = -30.3 – 10 + 37.9 = -2.4 dB. Antenna performance data over frequency is on the next page.

FCC ID: AZ489FT4850 RF POWER OUTPUT DATA The RF power output was measured with the indicated voltage applied to and current into the final RF amplifying device. Measured Conducted RF output (GMRS) 1.04 Watts Measured Conducted RF output (FRS) 0.580 Watts * Measured Radiated RF output (GMRS) 0.434 Watts * Measured Radiated RF output (FRS) 0.336 Watts Normal DC Voltage 4.20 Volts Normal DC Current (GMRS) 760 ma Normal DC Current (FRS) 542 ma Primary Supply Voltage 4.50 Volts RF Conducted output measured at 4.5v *Measured Radiated RF output. A fully assembled radio with the antenna mounted to the device was used for measuring Effective Radiated Power (ERP) for both FRS and GMRS bands using the substitution method. The radio was powered by AA Alkaline batteries and the transmitter keyed up by inserting a shorted pin in the microphone jack to activate the external PTT circuit. The maximum radiated power level observed was 25.26 dBm at 467.6125 MHz (FRS band) and 26.37 dBm at 462.6250 MHz (GMRS band). Therefore, the measured Effective Radiated Power (ERP) in Watts is: For FRS: ERP = 10^(25.26/10)= 10^2.526 = 0.336 Watts. For GMRS: ERP = 10^(26.37/10)= 10^2.637 = 0.434 Watts.
