Introduction Description The ASTRO Spectra compatible Vehicular Repeater System - Model 750 (VRS750) is a mobile radio system component that provides on-site repeater capability between a portable radio and a base station. The VRS gives the portable user the equivalent range of a mobile radio with the flexibility of a portable. The VRS is not an ASTRO-capable radio; instead, it is designed to interface with an ASTRO Spectra mobile radio. It can only transmit and receive clear analog transmissions. The VRS receives transmissions on the portable radio's transmit frequency with the proper access PL, and passes these portable signals to the mobile radio. The mobile radio re-transmits the signals to the base station on the mobile radio's transmit frequency. NOTE: These transmissions have the mobile's ID, not the portable's. Similarly, base station signals received by the mobile radio are sent to the VRS and re- transmitted to the portable radio. The VRS does not provide local repeater capability (received portable signals are not repeated on the portable receive frequency). The VRS-to…

FCC ID: AZ492FT4848 17 th January 2002 Mr. Stan Lyles Authorization & Evaluation Division Federal Communications Commission Laboratory 7435 Oakland Mills Road Columbia, MD 21046 Re: Form 731 Confirmation Number: EA856376 with FCC ID: AZ492FT4848. Dear Mr. Lyles; Motorola Inc., 8000 West Sunrise Boulevard, Fort Lauderdale, Florida 33322, herein submits its response to the 14 th January 2002 request for information in Correspondence Number 21747. Q1) The Modulation Limiting plots you have submitted, pages 6B-3 and 6B-4 of test report, are not acceptable. Please send plots showing the transmitter deviation as a function of input level for several different modulating tones - per Section 2.1047(b). R1) Transmitter deviation is presented as a function of modulation frequency in the plots in 6B-3 (Modulation Limiting versus Frequency). In those graphs, the modulating tone is swept from 100 Hz to 10 kHz. The frequency from 6B-3 which causes the greatest deviation (in this case, a 1 kHz audio tone) is used as the modulating tone in 6B-4, in which the audio input level is swept. Since other audio frequencies would generate lower deviation levels (as shown in 6B-3), the graphs in 6B-4 illustrate Modulation versus Input Audio Level results for the worst-case input frequency. Q2) The Users Manual should contain instructions for proper mounting of the unit, spacing from the antenna(s) to nearby persons and antenna gain limits to satisfy MPE limits. R2) The final version of the VRS 750 Detailed Service Manual contains instructions for proper mounting of the unit, pages iv and 7, spacing from the antenna(s) to nearby persons, page iv, and antenna gain limits to satisfy MPE limits on page iii.

Measurement data was taken with vehicle running at idle and vehicle battery measuring 14.0 volts. FCC ID: AZ492FT4848 Page 3 of 7 3.0 Test Results Measurements were taken with the antenna located in two areas: the roof center, and center trunk. A summary of results (highest level in each area) is in the following table. Antenna Location Antenna External/ Internal Highest Result Roof Center HAE4003 External 0.015 mW/cm 2 Center Trunk HAE4003 External 0.07 mW/cm 2 Roof Center HAE4003 Internal <= 0.036 mW/g (Equivalent SAR) Center Trunk HAE4003 Internal <= 0.036 mW/g (Equivalent SAR) Although the measured RF power of this radio was 4.1 watts, under any condition of permissible tuning, frequency, voltage, and temperature, the maximum RF power delivered to the antenna connector of this radio can be as high as 4.6 watts. As a result, the calculated power density (mW/cm 2 ) for the maximum power condition using the highest power density in the above table could be 0.079 mW/cm 2 . 4.0 Measurement System Uncertainty Levels Table 1.4 below lists an estimate of the possible errors that are associated with the measurement system.

Motorola, Inc. FCC ID: AZ492FT4848 MEASUREMENT PROCEDURES AND TEST EQUIPMENT USED Pursuant to 47CFR 2.947 7A RF Power Out – Pursuant to 47 CFR 2.1046(a) Method of Measurement: Per TIA/EIA-603-1 2.2.1 Before measuring the RF output power, the transmitter is adjusted in accordance with the tune-up procedure outlined in Exhibit 10 to give the value of voltage and current as specified in Exhibit 6A. The transmitter antenna port is then connected through an RF attenuator of the proper power rating to an HP 8901B Modulation Analyzer. 7B Occupied Bandwidth – Pursuant to 47 CFR 2.1049(b) Method of Measurement: Per TIA/EIA-603-1 2.2.11, TIA-EIA-102.CAAB 3.2.5 An audio oscillator is connected to the microphone input. The frequency is set to 2500 Hz and the amplitude is adjusted to a level 16 dB above that required to produce 50% of full system deviation at the frequency of maximum response of the audio modulating circuit, in accordance with FCC rules Part 2.989(a)(1). The transmitter output is connected, via a suitable attenuator, to an HP8568A spectrum analyzer. Spectrum analysis of the transmitter output is performed to at least +/- 2.5 times the channel spacing, first of the unmodulated carrier to establish a 0 dB reference, then with the modulated signal applied. FCC Limits -- Per 90.210 (a) (1), (2), (3) Emission Mask B – 25kHz channel bandwidth. For Transmitters that are equipped with an audio low-pass filter. Measured Data: (1) On any frequency removed from the assigned frequency by more than 50 percent, but not more than 100 percent of the authorized bandwidth: At least 25 dB. (2) On any frequency removed from the assigned frequency by more than 100 percent, but not more than 250 percent of the authorized bandwidth: At least 35 dB. (3) On any frequency removed from the assigned frequency by more than 250 percent of the authorized bandwidth: At least 43+10 log 10 (P) dB. Emission Mask D - 12.5kHz channel bandwidth. For Transmitters that designed to operate with 12.5Khz channel bandwidth, any emission must be attenuated below the power (P) of the highest emission contained within the authorized bandwidth as follows: Measured Data: (1) On any frequency from the center of the authorized bandwidth f o to 5.625Khz removed from fo: Zero dB. (2) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f d in kHz) of more than 5.625 kHz but no more than 12.5 kHz. At least 7.27 (f d - 2.88 kHz) dB. (3) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f d in kHz) of more than 12.5Khz: At least 50+10 log 10 (P) dB or 70 dB, whichever is the lesser attenuation . EXHIBIT 7 (1/4) Motorola, Inc. FCC ID: AZ492FT4848 7C Radiated Spurious Emissions – Pursuant to 47 CFR 2.1053 Test Site: The site, located at Plantation, Florida, is in a region reasonably free from RF interference and has been approved by the Commission for Spurious Measurements. Method of Measurement: Per TIA/EIA-603-1 2.2.12 The equipment is adjusted to obtain peak reading of received signals wherever they occur in the spectrum by: 1. Rotating the transmitter under test 2. Adjusting the antenna height The testing procedure is repeated for both horizontal and vertical polarization of the receiving antenna. Relative strength is indicated on the spectrum analyzer connected to the receiving antenna. To obtain actual radiated signal strength for each spurious and harmonic frequency observed, a standard signal generator with calibrated output is connected to a dipole antenna adjusted to that particular frequency. This dipole antenna is substituted for the transmitter under test. The signal generator is adjusted in output level until a reading identical to that obtained with the actual transmitter is observed on the spectrum analyzer. Signal strength is then read directly from the generator. Actual measurements are recorded on the attached graphs. The applied limits are those from FCC 90.210, radiated spurious emissions must be For 25 KHz channel bandwidth: 43 + 10log 10 (Power out in Watts) dB down from unmodulated carrier or equivalently less than -13 dBm (50 μW) absolute level. F or 12.5 KHz channel bandwidth: 50 + 10log 10 (Power out in Watts) dB down from unmodulated carrier or equivalently less than -20 dBm (10 μW) absolute level. 7D Frequency Stability – Pursuant to 47 CFR 2.1055 Method of Measurement: Per TIA/EIA-603-1 2.2.2 Temperature: Frequency measurements are made at the extremes of the temperature range - 30 to +60°C and at intervals of not more than 10°C throughout the range. Sufficient time is allowed prior to each measurement for the circuit components to stabilize. Power Supply Voltage : The primary voltage was varied from 80% to 120% of the nominal supply voltage. Voltage is measured at the output of the DC Power Supply. The limits are those from FCC 90.213: Frequency Stability vs. Temperature: < ±2.5 PPM Frequency Stability vs. Power Supply Voltage: < ±2.5 PPM 7E Modulation Limiting -- Pursuant to 47 CFR 2.1047 Method of Measurement: Per TIA/EIA-603-1 2.2.3 The transmitter shall be adjusted for full rated system deviation. Adjust the audio input for 60% of rated deviation at 1000 Hz. Using this level as a reference (0 dB), add 20 dB to the audio input level for modulation frequencies of 300, 1000, and 3000 Hz. The recorded system deviation obtained as a function of the input frequency is shown in Exhibit 6B-3. FCC 2.1047 also calls for curves showing percentage of modulation versus input audio level. The recorded system deviation obtained as a function of the input level is shown in Exhibit 6B-4. The transmitter modulation must not exceed rated system deviation at any audio frequency input or change in input level. EXHIBIT 7 (2/4) Motorola, Inc. FCC ID: AZ492FT4848 7F Audio Low Pass Filtering -- Pursuant to 47 CFR 2.1047 Method of Measurement: Per TIA/EIA-603-1 2.2.15 Using a dummy microphone to generate a 1000 Hz tone into the unit.
