MOTOROLA INC FCC ID: AZ489FT3794 TUNEUP PROCEDURE 8.0TUNING PROCEDURES This procedure was written in the sequence the radio is to be tuned. The following points should be noted: 1) Radio controller refers to the microprocessor in the radio. 2) Tester/test controller refers to external test system (hardware as well as software). 3) Values in tables may change to improve yield. 8.1.1PROGRAMMING I.C.S WITH DEFAULT DATA a) Power up radio. b) Program DAC for receive per table 9.2 c) Program the Fractional N for receive per table 9.6 - using the appropriate Band Select setting per table 9.9 - using the appropriate Rx. Frequency information. 8.1.2Synthesizer Reference freq setting: Set the internal synthesizer reference frequency selection to: TX RX Note: $01 selects 2.1Mhz, $10: 2.225MHz, $11:2.4MHz, $00 selects internal algorithm UHF $00 $00 VHF $00 $00 LB 800 $00 $00 8.1.3 REFERENCE OSCILLATOR AND TEMPERATURE COMPENSATION Reference oscillator frequency is 16.8Mhz unless stated otherwise in the table below: a) Read crystal data from the crystal body and enter into computer. ( A complete procedure on temperature compensation will be described later .) EXHIBIT 7 MOTOROLA INC FCC ID: AZ489FT3794 8.1.4 RATED AUDIO: a) Set radio to Carrier Squelch Test Environment and frequencies, LB VHF= F4 (154.925MHz) UHF = 438.05Mhz 800 = 860.525 MHz b) Inject a -47dBm RF signal modulated with a 1kHz tone at the 60% of rated deviation. c) Adjust the ASFIC Volume Attenuator (VOL7 - VOL0) to obtain 500mW of audio power into a speaker or equivalent resistive load, V=3.16V. d) Store the tuned Rated Volume Attenuator setting in the codeplug. NOTE 1: Maximum Volume = Rated Volume + Max Audio Overdrive (in normal operation mode) Max Audio Overdrive = 12.0dB 8.1.5 RECEIVER SQUELCH TUNING: ( Note that squelch adjustment can only be done after front end tuning is completed) The squelch softpots must be tuned for every channel spacing until production data shows otherwise a) Determine the frequency band of operation of the radio ( Low band, VHF, UHF, 800MHz etc...) b) Determine the radio channel spacing. That is 12.5KHz, 20KHz or 25KHz. c) Set radio channel spacing to 25KHz d) Set the radio to operate at frequency F1 (F5 for 800 MHz). e) Modulate the signal generator with 1KHz tone @ 60% of rated system deviation. See table 1 f) Set the RF level to -47dbm and then adjust the audio output for 50% rated audio. g) Set the ASFICcmp squelch attenuator (SQPOT5-0) to $0, to fully unsquelch the radio. h) Adjust the signal gen. RF level until 10db sinad is obtained (CCITT filter set to OFF). i) Increase the squelch attenuator settings (SQPOT5-0) until the speaker audio output is muted. j) Wait 500msec, monitoring for squelch chatter. If chatter is present, repeat step h. k) Repeat steps e to j for frequencies F2 to F7 (F6 to F7 for 800 MHz) that require tuning. Values for the untuned frequencies are to be interpolated by the test controller. l).Repeat step d to step k for the rest of the channel spacing. m) Program the squelch attenuator settings into the radio codeplug (Note: the radio application software adds a negative offset values to the squelch attenuators when the radio unsquelch. This effectively adds a hysteresis to the squelch performance thus improving squelch chattering.)

Note that the Dac for VHF/UHF is the DAC from the ASFIC a) Set radio to Carrier Squelch Test Environment. b) Program ASFIC to route the RSSI output to Universal connector c) The radio has 7 test points for Front End Bandpass filter, program the synthesizer to receive at the following test/tune frequencies Frequency Bands (MHz) Used in PAT UHF Band1UHF Band2UHF 300MHzVHF Test/Tune Freq403-470 F1402.975 136.225 F2413.025 142.225 F3425.025 148.225 F4437.025 154.625 F5449.025 161.225 F6460.025 167.225 F7470.025 173.625 DAC Start values for front end tuning.

It is recommended that a RC (1.5K-47uF) be added at the input of the voltmeter to reduce RSSI noise. f) PreSet the DAC value in the Front End Filter Softport with the DAC start values. g) Measure the RSSI voltage. Increment (vhf, decrement for uhf) the DAC value twice (VHF) and compare to the previous value h) Repeat until the change between the two latest RSSI reading is lower than the target value. UHF : 0.42%VHF : 0.5% i) Store the Front End Filter Softport in the codeplug For F1. (not for vhf) j) Repeat for other test point frequencies (F2-F7) that require tuning (not for VHF) For MOTOROLA INC FCC ID: AZ489FT3794 VHF calculate the offset from DAC value to the default value of F3 and add the offset to all softpot values. Note: if any calculation exceeds the minimum or maximum softpot value set the softpot to the minimum or maximum value. Band owners should define the minimum value to prevent varicap problems. 8.1.7 RSSI slope selection bit settings: These settings sets the RSSI slope selection in the ZIF at power up: 20-25KHz Channel spacings LBVHFUHF800 Bit 24Bit 25Bit 26Bit 24Bit 25Bit 26Bit 24Bit 25Bit 26Bit 24Bit 25Bit 26 111111000 12.5KHz Channel spacings: LBVHFUHF800 Bit 24Bit 25Bit 26Bit 24Bit 25Bit 26Bit 24Bit 25Bit 26Bit 24Bit 25Bit 26 111111000 8.1.8 RSSI display tuning for RSSI level1 to RSSI level 6 There are 6 RSSI display bars for models that …

MOTOROLA INC FCC ID: AZ489FT3794 CIRCUIT DESCRIPTION The following schematic diagrams will be similar to those that appear in the final service manual. A general description of the overall circuit is covered in the instruction manual. This section provides the description of circuits required by subpart 2.983 of the Commission’s rules. The following are included: 1. Means of Frequency Stabilization8A 2. Means for Limiting Modulation and Low Pass Filtering8B 3. Means of Attenuating Spurious Emissions8C 4. Means for Limiting Power8D EXHIBIT 8 Section 8A - Description for determining and stabilizing frequency MOTOROLA INC FCC ID: AZ489FT3794 This product uses a frequency synthesizer to generate the transmitter signal which is then applied to the transmitter power amplifier. The frequency stability of the output signal from the synthesizer is determined by the stability of the reference frequency applied to the synthesizer input. The figure above shows the frequency synthesizer with the appropriate circuitry highlighted. The reference frequency for the synthesizer is 16.8 MHz. This is determined by the crystal component indicated as Y3761 in the figure. Notice also that a varactor, D3761 is connected to one side of the resonator. By varying the voltage applied to the varactor, the frequency of the reference oscillator can be varied. This voltage is supplied from Pin 25 of U3701 and is called the warp voltage. The reference oscillator active device is internal to U3701 and connects to the resonator at pins 23 and 24. The center frequency of crystal resonators varies in a mathematically predictable way over temperature and following a known polynomial curve. Due to production variations, the coefficients of the curve are slightly different for each crystal. To account for this each crystal is individually characterized and labeled. The integrated circuit U3701 contains circuitry which senses the ambient temperature and adjusts the warp voltage to track out the variation in resonator center frequency over temperature. This circuitry is designed to be custom programmed for the slight variations in crystals that are indicated on the crystal label. At the time of production, the label is read and the correct adjustments are programmed into the radio. The reference oscillator is power off a regulated supply voltage. This eliminates variation of the frequency with battery voltage.

This IC takes audio from either the internal or external microphone and performs the necessary processing and outputs modulation information to the synthesizer. The figure below will help explain in the discussion of this operation. Audio from the microphone is routed to a microphone preamp which adjusts for the differences in sensitivity between internal and external microphones. The signal is then routed to a four pole low-pass filter to bandlimit the signal to 4 kHz and then through a highpass filter which remove energy in the low frequency part of the spectrum which is used for signaling. The signal is the preemphasized and then sent to a limiter. This nonlinear circuit clamps the peak value of the audio signal. By limiting this peak value of the audio waveform, we are able to limit the peak value of modulation output to the synthesizer and thereby peak deviation from the transmitter. After the limiter, the audio is passed through a 5 pole low-pass splatter filter to remove higher frequency energy and then subaudible signalling such as CTCSS is summed in. This…
