This radio isdesigned for and classified as“Occupational Use Only,” meaning itmust be used only during the course of employmentby individuals aware of the hazards and the ways tominimize such hazards. This radio is NOT intended foruse by the “General Population” in an uncontrolledenvironment.The P7100PI portable radio has been tested andcomplies with the FCC RF exposure limits for“Occupational Use Only.” In addition, this M/A-COM radiocomplies with the following Standards and Guidelines withregard to RF energy and electromagnetic energy levelsand evaluation of such levels for exposure to humans:· FCC OET Bulletin 65 Edition 97-01 Supplement C,Evaluating Compliance with FCC Guidelines forHuman Exposure to Radio Frequency ElectromagneticFields.· American National Standards Institute (C95.1 – 1992),IEEE Standard for Safety Levels with Respect toHuman Exposure to Radio Frequency ElectromagneticFields, 3 kHz to 300 GHz.· American National Standards Institute (C95.3 – 1992),IEEE Recommended Practice for the Measurement of
4Potentially Hazardous Electromagnetic Fields – RFand Microwave.CAUTIONTo ensure that exposure to RFelectromagnetic energy is within the FCCallowable limits for occupational use,always adhere to the followingguidelines:· DO NOT operate the radio without a proper antennaattached, as this may damage the radio and may alsocause the FCC RF exposure limits to be exceeded. Aproper antenna is the antenna supplied with this radioby M/A-COM or an antenna specifically authorized byM/A-COM for use with this radio.· DO NOT transmit for more than 50% of total radio usetime (“50% duty cycle”). Transmitting more than 50%of the time can cause FCC RF exposure compliancerequirements to be exceeded. The radio istransmitting when the “TX” indicator appears in thedisplay. The radio will transmit by pressing the “PTT”button.· ALWAYS use M/A-COM authorized accessories(antennas, batteries, belt clips, speaker/mics, etc).Use of unauthorized accessories may cause the FCCOccupational/Controlled Exposure RF compliancerequirements to be exceeded.
5· ALWAYS keep the device and its antenna at least 2cm (0.8 inches) from the body and at least 5 cm (2inches) from the face when transmitting to ensure FCCRF exposure compliance requirements are notexceeded. This radio has been tested for RF exposurecompliance at the distances listed in Table 1.However, to provide the recipients of yourtransmission the best sound quality, hold the antennaat least 5 cm (2 inches) from mouth, and slightly off toone side.Table 1: RF Exposure Compliance Testing DistancesTested Distances(worst case scenario)RadioFrequencyBody Face800 MHz 1.6 cm 2.5 cmVHF ( MHz) 1.1 cm 2.5 cmThe information listed above provides the informationneeded to make the user aware of a RF exposure, andwhat to do to assure that this radio operates within the FCCRF exposure limits of this radio.ELECTROMAGNETIC INTERFERENCE/COMPATIBILITYDuring transmissions, this M/A-COM radio generatesRF energy that can possibly cause interference with otherdevices or systems. To avoid such interference, turn off

7OPERATING RULES AND REGULATIONSTwo-way FM radio systems must be operated inaccordance with the rules and regulations of the FederalCommunications Commission (FCC). As an operator oftwo-way radio equipment, you must be thoroughly familiarwith the rules that apply to your particular type of radiooperation. Following these rules will help eliminateconfusion and will assure the most efficient use of existingradio channels. This will provide a smooth operating radionetwork.When using the radio, remember these rules:1. It is a violation of FCC rules to interrupt any distress oremergency message. As the radio operates in muchthe same way as a telephone "party line" when inconventional mode, always listen and/or observe theabsence of the “busy” display (refer to Table 2 – ThreeLine Display for display character) to make sure thatthe line is clear before sending any messages. Ifsomeone is sending an emergency message, such asreporting a fire or asking for help in an accident, KEEPOFF THE AIR! Emergency calls have priority over allother messages.2. Use of profane or obscene language is prohibited byFederal Law.3. It is against the law to send false call letters or a falsedistress or emergency message.
84. The FCC requires that conversations be brief andconfined to business. To save time, use codedmessages whenever possible.5. Using the radio to send personal messages (except inan emergency) is a violation of FCC rules. Send onlythose messages essential for the business operation.6. It is against Federal Law to repeat or otherwise makeknown anything overheard on the radio. Conversationsbetween others sharing your channel must beregarded as confidential.
9OPERATING TIPSAntenna location and condition are important whenoperating a portable radio. Operating the radio in low lyingareas or terrain, under power lines or bridges, inside of avehicle or in a metal or steel framed building can severelyreduce the range of the unit. Mountains can also reducethe range of the unit.In areas where transmission or reception is poor, someimprovement may be obtained by ensuring that theantenna is vertical. Moving a few yards in another directionor moving to a higher elevation may also improvecommunications. Vehicular operation can be aided with theuse of an externally mounted antenna.Battery condition is another important factor in thetrouble free operation of a portable radio. Always properlycharge the batteries.EFFICIENT RADIO OPERATIONHold the portable radio approximately three inches fromyour mouth and speak into the microphone at a normalvoice level.Keep the antenna in a vertical position when receivingor transmitting a message.Do not hold the antenna when receiving a messageand, especially, do not hold when transmitting a message.
10WARNINGDo NOT hold onto the antenna whentransmitting.Antenna Care and ReplacementWARNINGAlways keep the antenna at least 0.8 inches(2 cm.) away from the body and 2 inches (5cm.) from the face when transmitting toensure FCC RF exposure compliancerequirements are not exceeded.WARNINGDo not use the portable radio with a damagedor missing antenna. A minor burn may resultif a damaged antenna comes into contactwith the skin. Replace a damaged antennaimmediately. A missing antenna coulddamage your portable radio.WARNINGUse only the supplied or approved antenna.Unauthorized antennas, modifications orattachments could damage the radio unit andmay violate FCC regulations.
11Electronic DevicesCAUTIONRF energy from your portable radio mayaffect some electronic equipment. Mostmodern electronic equipment in cars,hospitals, homes, etc. are shielded from RFenergy. However, in areas that instruct you toturn off two-way radio equipment, alwaysobserve the rules. If in doubt, turn it off!AircraftWARNINGAlways turn off your portable radio beforeboarding any aircraft!· Use it on the ground only with crewpermission.· DO NOT use while in-flight!!Blasting AreasWARNINGTo avoid interfering with blasting operations,turn your radio OFF when in a "blasting area"or in areas posted "turn off two-way radio."Remote control RF devices are used by someconstruction crews to set off explosives.
12Potentially Explosive AtmospheresWARNINGAreas with potentially explosive atmosphereare often, but not always, clearly marked.These may be fueling areas, such as gasstations, fuel or chemical transfer or storagefacilities, and areas where the air containschemicals or particles, such as grain, dust ormetal powders.Sparks in such areas could cause anexplosion or fire resulting in bodily injury oreven death.Turn OFF your radio when in any area with apotentially explosive atmosphere. It is rare,but not impossible that the radio or itsaccessories could generate sparks.

1FCC ID : OWDTR-0013-E INSTRUCTION BOOK (DRAFT) J725P VHF 1. Receiver Circuit The FM dual-conversion super heterodyne receiver is designed for operation in the 136-174 MHz frequency range. The Receiver has intermediate frequencies (IF) of 115.65MHz and 450kHz. Adjacent channel selectivity is obtained by using two band pass filters, a 115.65MHz crystal filter and a 450kHz ceramic filter. The RX detector is the phase digitizer. 1-1 Receiver Front-end A RF signal from antenna is coupled though the low pass filter/antenna switch, and band pass filter to the input of low noise amplifier Q101. The output of Q101 is coupled through band pass filter to input of 1’st Mixer Z101. Front End selectivity is provided by these band pass filter. 1-2 1’st Mixer The 1’st Mixer is a Double-Balanced-Mixer Z101, that converts a RF signal the 136-174MHz range to 115.65MHz 1’st IF frequency. The signal on the output of Z101 is provided to the input of 1’st IF amplifier Q102. 1-3 1’st IF The 1’st IF signal 115.65MHz from the output of the 1’st Mixer is coupled through 1’st IF amplifier Q102 to Crystal filter FL103. The highly-selective crystal filter FL103 provide the first portion of the receiver IF selectivity. The output of the filter is coupled through the impedance-matching net work to IF Receiver U101. 1-4 2nd Mixer, 2nd IF filter and 2nd IF amplifier IF Receiver U101 is an one-chip IC for digital communication system. It includes 2’nd Mixer, 2’nd IF amplifier and Limiter amplifier. With the internal circuits of U101, The 1’st IF signal is amplified and applied to the input of 2’nd Mixer. The 2’nd local injection frequency 115.2MHz is applied from 2’nd local amplifier Q106 to another input of the 2’nd Mixer. The 2’nd Mixer converts a 1’st IF signal 115.65MHz to 2’nd IF frequency 450KHz. Then the 2’nd IF signal is applied to Ceramic Filter FL105(Wide Band) or FL106 (Narrow Band&C4FM), which provides the 450KHz selectivity. Those IF filters are controlled by IF.NARROW signal from the microcomputer (HILLARY:U700). The output of the 2’nd IF filter is applied through 2’nd IF
2amplifier and Ceramic Filter FL104 or FL107 to Limiter amplifier. Those IF Filters are controlled by C4FM. DATA signal from the microcomputer (HILLARY:U700). This IF signal is amplified and balanced outputs, RXIF and RXIF, are sent to HILLARY. These two lines, one positive and the other negative, are used to cancel out any noise that might get on the line. These balance outputs is applied to the phase digitizer on HILLARY and detected. 2, Transmitter Circuit The Transmitter Circuit consists of Buffer Amplifier (U202 and Q202), PA Module (U201). Automatic Power Control Circuit (Q421, Q422 and U404), Antenna Switch Module (Z302). The initial drive level for the transmitter is the Tx VCO. The VCO frequency range is 136 to 174MHz. 2-1 Buffer Amplifier The output of VCO is applied to the Buffer Amplifier U202. The collector voltage for U202 is provided Switch circuit and is controlled by DPTT. The output of U202 is applied to the Buffer Amplifier Q202 input that is amplified to +8dBm. The output of U202 is applied to PA module input. 2-2 PA Module The input of the PA Module is amplified to about 7W. B+ (7.5 V DC) is connected U201 through RF chokes L251. The PA Module consists of two stages RF amplifier. The first stage power supply voltage is supplied by power control circuit. The second RF amplifier operates in Class-C. This output can be regulated by power control circuit. 2-3 Automatic Power Control The Automatic Power Control circuit samples the output power to the antenna to maintain a constant power level across the band. The Automatic Power Control circuit controls the Vcont voltage to PA Module U201. Directional coupler is include of Antenna Switch Module(Z302). Directional coupler provides a sampled signal of transmit power for diode. Diode produce a positive DC voltage proportional to the transmitter circuit output power level, that is compared to a comparator (U404) from TX POWER CONT of control unit. The output of U404 is applied to DC amplifier Q422, then the output voltage of Q422 controls to the Vcont of PA Module for constant output power level.
32-4 Antenna Switch Module The Antenna Switch Module consists of switch circuit and the Low Pass Filter. During transmit, DPTT line from HILLARY is high level. Transistor Q403 turns on supply +7.2V to Antenna Switch Module Z302. When transmitting, the Antenna switch diode is low impedance. 3. Frequency Synthesizer Circuit It consists of the Reference Oscillator, PLL Frequency Synthesizer chip U305, Loop filter, Rx VCO Z303, and Tx VCO Z304. PLL Frequency Synthesizer chip receives PLL data, and control information from the microcomputer and from this generates the Tx/Rx RF frequencies. It also provides frequency lock status to the microcomputer. Rx VCO and Tx VCO are locked to the Reference Oscillator by a single direct-divide synthesis loop consisting of the Feedback Buffer, Prescaler, and PLL Frequency Synthesizer chip. The Tx VCO operates over a frequency range of 136-174MHz. The Rx VCO operates over a frequency range of 251.65-289.65MHz. 3-1 Reference Oscillator The reference oscillator consists of a 1.5ppm TCXO (Temperature Controlled Compensated Crystal Oscillator). The standard of reference oscillator frequency is 19.2MHz. The TCXO is enclosed in a RF shielded can. The TCXO is compensated by internal temperature compensated circuit for both low and high temperature. With no additional compensated the oscillator will provide 1.5 PPM stability from -30°C to +60°C. 3-2 Fractional-N Frequency Synthesizer chip Fractional-N Frequency synthesizer chip U305 provides fractionality through the use of main ∆Σ modulators. The output from the modulators are combined with the main and auxiliary divider ratios through their respective Fractional Units. The reference frequency 19.2MHz from the crystal oscillator is divided by a ratio of 1 to 32 to create the reference frequencies for the phase detectors. The divide ratios can be programmed through the Reference Frequency Dividers Register. The dividend is Desired VCO division ratio in fractional-N applications. This number is a real number and can be interpreted as the reference frequency (F ref ) multiplying factor such that the resulting frequency is equal to the desired VCO frequency. When in 18-bit mode, 18-bit signed input value to the ∆Σ modulator, ranging from -131072 to +131071
4providing 262144 steps, each of F div_ref / 2 18 (Hz). The divider is 262144 when the ∆Σ modulator is in 18-bit mode. With the modulator in 18-bit mode, the value to be programmed in the Main Dividend register is programmed by the microcomputer. This results in an error voltage when the phase differ and a constant output voltage when phase-detector input compare in frequency and phase. If a phase error is detected, an error voltage is developed and applied to the VCO DC offset and loop filter to reset the VCO frequency. The dividend is controlled by the frequency data received on the SC.CLK, SC.DATA - and SC.SYN1LE- line from the microcomputer. When a different channel is selected or when changing to the transmit or receive mode an error voltage is generated and appears at the phase-detector output, causing the Phase Locked Loop to acquire the new frequency. 3-3 Loop filter The Loop filter consists of R341 or R322 through R327 and C336 through C341and Analog SW (U304, U309). This filter controls the bandwidth and stability of the synthesizer loop. When a different channel changing or changing to transmit or receive mode, analog switch is controlled by VCO RX/TX for PLL lock up first. The output of the filter is applied to the variable capacitors in transmit and receive VCO to adjust and maintain the VCO frequency. The use of to VCO allows rapid independent selection of transmit and receive frequencies across the frequency split. 3-4 Rx VCO The Rx VCO consists of low-noise silicon transistor oscillator, and followed by high-gain buffer. The VCO is switched on and off VCO RX/TX line. When VCO RX/TX is low, the Rx VCO is turned on, transistor Q301 is on. The Rx VCO output is typically 0dBm. The output is applied to the PLL Frequency Synthesizer chip for VCO frequency control and as the Receiver frequency to Rx 1’st Mixer through the 1’st Local oscillator buffer amplifier. The VCO voltage need only be set once at some frequency of the band and split, after which it operates over the entire split with no additional tuning. 3-5 Tx VCO The Tx VCO is basically the same as the Rx VCO. The Tx VCO has the modulation terminal for FM. The VCO consists of silicon transistor oscillator followed by high-gain buffer amplifier. When VCO RX/TX is high, the Tx VCO is turned on, transistor Q302 is on.
5 3-6 Lock Detect The Lock Detect signal is outputted from synthesizer IC (U305-9). The LOCK(U305-9) is low if a large frequency error exist, and will carry unlock condition to the microcomputer.
