CIRCUIT DESCRIPTION-MPU32BDI GENERAL INFORMATION The MPU99BL/32BL/08B has three printed circuit boards; CPU board, Radio Frequency(RF)board, Audio Frequency (SUB)board. The CPU board contains the Microprocessor/Control section. The RF board contains the VCO/ Synthesizer section, Transmitter section and Receiver section. The SUB board contains the Transmitter Audio circuitry and the Receiver Audio circuitry. Circuitry is described in the following order: Microprocessor/Control Section, VCO/Synthesizer Section, Transmitter Section, Receiver Section and Battery Section. Refer to the Block Diagram and the Schematics. MICROPROCESSOR/CONTROL SECTION The microprocessor 0105 is constantly operating when the radio is turned ON. It is continuously monitoring the channel selector switch, The PTT line and other internal inputs such as the squelch detect, etc. When a change occurs, the microprocessor makes the appropriate response. The microprocessor is used for control. The Radio emits a beep on channel change and the synthesizer is loaded with the correct frequency information. The microprocessor runs off a 4.19 MHz oscillator which is composed of X101, C127, C128, and R128. When the radio is first turned on, the microprocessor reads the radio status from the EEPROM 0104. "-..@'The microprocessor determines the receive frequency codes, then loads the synthesizer via its pins 17, 19 and 42. VCD/SYNTHESIZER SECTION This section consists of the Temperature-Compensated Crystal Oscillator (TCXO), Voltage Controlled Oscillator(VCO), Synthesizer and the Loop Filter. These circuits are found on the RF board. Temperature-Compensated Crystal Oscillator(TCXO) The reference oscillator is a temperature compensated crystal-controlled, Pierce type circuit. It utilizes a logic gate within Q402 as a gain element. C407 is used to adjust the oscillator on frequency (6.4MHz) at room temperature (22'C). Temperature variations cause resistance changes it-, thermistor R410, which is oi the base of 0404, thus varying the voltage applied to varactor 0403. This changes the impedance across crystal X401 in a manner complementary to the temperature drift characteristic of the crystal. In this way,the reference oscillator is held within the specified ±2.5 PPM from -30 to +60'C. Voltage –Controlled Oscillators(VCO) Only one of the VCOs run at a time, which is controlled by the +SVTX (W402 Pin3) and 0441. When the PTT is pressed, +5VTX goes high (approx.5V) disabling the receive VCO and biases on 0428 to enable the transmitter VCO. Both the receive and t@ansm0er VCOs are Colpitts type oscillators. The receive VCO consists of C422-C425, C540, L401 -L403, and Q410-041 1. This VCO oscillates at 34.3 MHz below the programmed receive frequency. The VCO's oscillating frequency is tuned by the varactor 0410. The tuning voltage is supplied from the output of the Loop Filter. The output of the VCO is AC coupled (C428 and C429) to the synthesizer input buffer 0426 and the output buffer 0412 respectively. The transmitter VCO consists of C472-C475, L414-L416, and 0427-0428. This VCO oscillates on the programmed transmit frequency. The VCO's oscillating frequency is tuned by the varactor 0427. The tuning voltage is supplied from the output of the Loop Filter The output of the VCO is AC coupled (C479 and C481) to the synthesizer input buffer 0429 and the output buffer 0426 respectively. The transmit voltage controlled oscillator is directly frequency-modulated and operates on the carrier frequency. In the receive mode, the transmit VCO is disabled and the receive VCO is enabled, producing the receive local oscillator signal at a frequency 34.3MHz below the incoming receive frequency. The synthesizer is tuned in 5kHz or 6.25kHz steps. Synthesizer The frequency synthesizer is a large scale monolithic synthesizer integrated circuit 0402. The synthesizer IC contains a dual modular prescaler, programmable divide-by-N counter, prescale control (swallow) counter, reference oscillator, reference divider, phase detector, charge pump and lock detector. Also, included in Q402 are shift registers and control circuits for frequency controls and general device control RF output from the active VCO is beered by 0426 and AC coupled to the synthesizer 0402 prescaler input at Pin 8. The divide-by-N counter chain in 0402, consisting of the dual-modulus prescaler, swallow counter and programmable counter, dmdes the VCO signal down to a frequency very close to 5.OOkHz or 6.25kHz, which is applied to the phase detector. The phase comparator compares the edges of this of this signal with that of the 5.OOkHz or 6.25MHz reference signal from the reference divider and drives the external charge pump (Q407 and 0408). The synthesizer unlock detector circuit prevents the operation of the transmitter, when the phase lock loop (PLL) is unlocked. The following discussion assumes the unit has been placed in the transmit mode. 0402 lock detector Pin 7 goes high when the PLL is locked. C414 charges through R417 cutting off 0406, then 0401 goes into cutoff thus applying a high to Pin 17 of the microprocessor 0105. A software timing routing brings the RXITX line low (Pin 6 of Ql 01). With the RX/TX line low, 0222B is cut off and Q221 B is biases on passing +5VTX(W402 Pin3) to saturate Q445B. After 0445 goes into saturation, ft biases on 0444 to pass switched battery B+ to the transmitter amplifier string which enables transmission. Should the PLL become unlocked, the lock detector at Q402 Pin7 will begin pulsing low. C414 quickly discharges, biasing on Q406. This, in turn, saturates Q401, presenting a low to the microprocessor. The microprocessor then changes the RX/TX line to a high, thus signaling the other transistor switches to drive Q444 into cutoff which disable transmission. Therefore, the transmitter remains disabled while the loop remains out of lock. Loop Filter The Loop Filter, a passive lead-lag filter consisting of R427-R429 and C417-C418, integrates the charge pump…

May 1, 2001 FCC ID O78SCV99L 1. The portable radio, O78SCU99BL, is a push to talk radio (PTT). The duty factor will not exceed 50%. In actual usage, the duty factor is 5% or less. The radio does not have the capability to operate in a full duplex mode and any attempt to operate in a continuous CW mode by holding the PTT button ‘IN’ will result in the transmitter “un-keying” due to the time out timer or dying due to battery. 2. There is a belt clip option which is used to carr y the radio on the belt during the receive mode. The user manual contains warnings not to use the radio transmit mode while on the user’s belt. 3. Shown below are various operator manuals which were later modified for the inclusion of RF exposure warnings. “To maintain compliance with FCC RRF exposure guidelines, DO NOT TRANSMIT WHILE USING THE BELT CLIP. The belt clip is for carr ying purposes only.” 4. The user is advised to hold the radio at least 2” away from the head when transmitting. 5. The user manual has been written to warn the user not to substitute an antenna that is different than the antenna supplied by the manufacturer. Sincerely, Walter C Simciak Chief Engineer 5481 SAND LAKE DRIVE, MELBOURNE,FLORIDA • 32934 PHONE: 321-255-0329 • FAX: 321-255-0329

SAR Analysis In this section, the Smart Communications Ltd. O78SCU99BL is compared against comparable equipment that has been tested in detail under procedures specified in FCC Part 2.1093, ET Docket 96-326 (Rules for controlled exposure for mobile and portable devices.) These units manufactured by other corporations have been tested using procedures as described in American National Standards Institute C95.1-1992 (1), FCC OET Bulletin 65-1997 and the data has been posted on the FCC internet site. Exposure from a portable radio is primarily controlled by the radio’s power output, antenna and case size, accessories, and position to the human body. There is no circuitry that would affect the exposure. It is a physical property asstated. Therefore, Smart Communications Ltd. believes it’s equipment is so similar that the radiated fields would be so nearly identical or less than the ICOM IC-F40GT-2 (other than the Face-Held configuration which was closer than what is recommended in the manual or what is normal in the industry), that detailed expensive testing should not be necessary. Smart Communications Ltd.’s equipment, O78SCU99BL, is to be used only in controlled environments which are defined as locations where there is potential exposure of individuals who have knowledge of their potential exposure and can exercise control over their exposure. This environment is typical of the business and public safety sections of the land mobile radio industry which is the market for this equipment.

The unit is typically used in a face-held configuration with the front of the device placed parallel to and at a Caution Device restricted to occupational use to satisfy FCC RF exposure compliance. See owner’s manual for full details. Enlarged Label nominal dstance of two inches (79 mm) from the face. (SAR testing on the Vertex unit was done at 40 mm while the ICOM unit was done at 20 mm for this mode of operation. This close distance of the ICOM is not normal in the industry.) Antenna supplied by Smart Communications Ltd. is a ¼ wave monopole with 0 dBd gain which is the same type of antenna supplied by the other units. (This is the typical “rubber duck” style.) Operation in a body-worn configuration with the rear of the device placed parallel to the surface of the body, with the attached belt-clip touching the outer surface and with a 1.0 cm separation distance between the rear of the unit and the body. (SAR testing on the Vertex and ICOM units was done in this manner.) The results of the Vertex and ICOM SAR measurements (worst case) is shown below. The Smart Communications Ltd. Inc O78SCU99BL is operated much like the Vertex unit as the Smart Communications Ltd. microphone is located in the same area on the radio body as the Vertex unit. The microphone audio circuitry has been designed for the user to operate the unit with several inches distance between the microphone and user and thus would be represented by the Vertex Face-Held radiated. The body worn measurement should be nearly identical to the ICOM measurements as the antenna is the same length and the radiated power is the same between the Smart Communications Ltd. and ICOM units.

Based on the identical or lower radiated power between these three units, the similar size, and mode of operation, Smart Communications Ltd. Inc. contends that the Smart Communications Ltd. O78SCU99BL unit meets the FCC requirements for SAR. The radiated power is the same as the approved ICOM units and lower than the Vertex unit. The antenna length is the same as the other units. The physical length of the unit is about the same as the ICOM and Vertex units. The belt clips are nearly identical in size and all made out of plastic. An updated user manual has been also provided with improved SAR information.

Then the Push-to-Talk button is pushed it sends out radio frequency signals. The device is authorized to operate at a duty factor not to exceed 50%. In august 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels for hand-held devices USE only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transceiver and may violate FCC regulations. CAUTION! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform the best if the microphone is 2 to 4 in (5 to 10 cm) away from the lips and the transceiver is held in the vertical position. NEVER operate the transceiver with a headset or other audio accessories at high volume levels. NEVER short the battery terminals. NEVER press the PTT key unless transmitting. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below +14 F (-10 C) or above +122 F (+50 C). The basic operations, transmit, receive are guaranteed within the specified operating temperature range. DO NOT modify the transceiver for any reason SAFETY INFORMATION Your transceiver generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as “Occupational Use Only” meaning it must be used during the course of employment by individuals aware of hazards, ant the techniques to minimize such hazards. This radio in NOT intended to be used by the General Public, and in an uncontrolled environment. This radio has been tested and complies with the FCC RF exposure limits for “Occupational Use Only”. The radio also complies with the following standards regarding to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: • FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to radio Frequency Electromagnetic Fields. • American national Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to radio Frequency Electromagnetic Fields, 3kHz to 3000 GHz. 3 • American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields- RF and Microwave. TO ENSURE THAT YOUR EXPOSURE TO RF ELECTROMAGNETIC ENERGY IS WITHIN THE FCC ALLOWABLE LIMITS FOR OCCUPATIONAL USE, ALWAYS ADHERE TO THE FOLLOWING GUIDELINES: • Do not operate the radio without a proper antenna attached, as this may cause damage to the radio as well as cause the RF exposure to exceed the FCC limits. The proper antenn is supplied with the radio, do not use any other antenna not approved by the manufacturer. • Do not transmit more than 50% of the total radio use time. Transmitting more than the recommended 50% can cause FCC RF exposure requirements to be exceeded. The radio transmits when the PTT switch is pushed and the RED TX LED (indicator) is illuminated. • Always use SmartComm USA authorized accessories (antennas, batteries, speaker microphones, belt clips, etc). Use of any unauthorized accessories can cause the RF exposure to exceed the FCC limits. • Always keep the antenna at least 1cm (3/8 in) away from the body when transmitting to ensure that the FCC exposure limits are not exceeded. To ensure the best signal quality, hold the antenna at least 5 cm (2 in) from the mouth and slightly to one side. ELECTROMAGNETIC INTERFERENCE / COMPATIBILITY During transmissions the radio generates RF energy that can possibly cause interference with other systems or devices. To avoid such interference never operate the radio in RX or TX where signs are posted not to use transceivers. Do not use the radio in areas that are sensitive to electromagnetic radiation. Some examples of these locations are hospitals, blasting sites and airports. 4…
