Applicant: Shintom Co., Ltd.Transmitter Type: BFYT3017 TECHNICAL DESCRIPTION The transmitter has been specially designed for the Domestic Public Cellular Radiotelephone Communications Service. The rated maximum power output is 3 watts with the capability of reducing the maximum power in seven steps of 4dB each on command from a Base Station. Each power level is maintained within +2/-4 dB of its nominal level over the temperature range from -30 to +60 degrees Centigrade and +15/-15 % change of the supply voltage, accumulative. This transmitter operates in the frequency range of 824.04 to 848.97 MHz. The frequencies are generated by Phase Locked Loop Frequency Synthesizers which are controlled by the closest Base Station in the system and the frequency stability of carrier is better than ±2.5 ppm. The transmitter is equipped with an audio compressor having 2:1 syllabic compandor, a pre-emphasis audio circuit having a 6dB/octave response, an instantaneous deviation limiter to limit deviation to ±12KHz, and a post deviation limiter filter having a -48dB/octave response above 3000 Hz. The transmitter carrier frequency is generated by a Phase Locked Loop (PLL) circuit. The PLL circuit consists of a TX Voltage Controlled Oscillator (TX VCO, MX301), a PLL integrated circuit (IC301), a loop filter and a reference frequency oscillator (TCXO system, see Pages 4 to 6 of Exhibit 3). The frequency of the TCXO system is 14.4 MHz with stability better than ±2.5ppm over the temperature range of -30 to +60 degrees Centigrade. The frequency of TCXO system can be controlled by AFC (Automatic Frequency Control) circuit so that the receiving frequency agrees with the Base Station transmit frequency. In this mode, the frequency stability of TCXO system is maintained within ±1.0ppm over the temperature range of -30 to +60 degrees Centigrade. The reference divider provides a reference signal to the phase comparator by dividing an output of the TCXO system. The programmable divider, which is controlled by digital circuitry, provides a signal to the phase comparator by dividing an output of the TX VCO (MX301). The phase comparator controls a frequency of the TX VCO through the charge pump and the loop filter so that the phase of the signal from the programmable divider agrees with the phase of the reference signal. Therefore, the frequency of the TX VCO is controlled by the digital circuitry with the stability of the TCXO system. The TX PLL synthesizer provides a RF signal to TX driver AMP(Q203). EXHIBIT 4 PAGE 1 OF 2 Applicant: Shintom Co., Ltd.Transmitter Type: BFYT3017 TECHNICAL DESCRIPTION (Continued) The TX PLL circuit also acts as a frequency modulator which provides the peak frequency deviation within ±12 KHz and the constant deviation and low distortion within the operating bandwidth. The frequency modulator is preceded by a Signal Audio Processing LSI (IC403) which contains a band pass filter, compressor, pre-emphasis, limiter, post-limiter filter, and a mute switch, to provide appropriate voice band processing. Supervisory Audio Tone (SAT), Signaling Tone (ST), and Wide Band Data (WBD) are generated within the Signal Audio Processing LSI (IC403) which is controlled by Microprocessor (IC601), and transmitted to the frequency modulator through the filter included in the Signal Audio Processing LSI (IC403). The power amplifier circuit, which consists of a RF power amplifier module (IC201), a band pass filter (F202), the driver (Q203), and a power control circuit, amplifiers the 0.3 milliwatt from the TX PLL synthesizer circuit and provides at least 5 watts output. The output of the power amplifier is connected to an antenna terminal through a directional coupler (F203) and a Band Pass Filter (F101). The output of the power amplifier provides adequate margin to compensate for losses in the directional coupler and bandpass filter. The Power Control circuit (APC) consists of a power level detector (D201), comparator (IC202), and a DA converter incorporated in IC601. The power detector provides the comparator with a DC voltage which indicates the power level. The D/A converter, which is controlled by the digital circuitry provides the reference DC voltage to the comparator. The comparator controls the RF power amplifier module so that the voltage detected by the power level detector is equal to the reference voltage. The D/A converter converts the binary data from the digital circuitry into the analog reference voltage. Binary data, which corresponding to the eight different power levels, is stored in the EEPROM of the digital circuitry and controls the power level adjustment. The transmitter has the capability of reducing the maximum output power level in 7 steps of 4 dB each. The digital circuitry continuously monitors the power output at the output of the power detector. If the power output is detected and the CARRIER ON command is not enabled by the digital circuitry, the transmitter ill be deactivated through independent action of controlling TX Enable Switch (Q301) to turn off the power of TX VCO (MX301) and through action of controlling Power Supply Switch (Q201) with signal (TXTS) to turn off the power of RF Power Amp. Module (IC201), TX Driver Amp (Q203) and Automatic Power Control (IC202). EXHIBIT 4 PAGE 2 OF 2

Re:Response to Correspondence – Correspondence Reference Number: 13064 FCC ID: BFYT3017 Form 731 Confirmation Number: EA96744 Applicant: Shintom Co., Ltd. Dear Mr.Dichoso, The followings are response to your correspondence. 1) The SAR configuration used was selected to simulate worst case condition of exposure to the head of a tall person sitting directly under the antenna. The cable used for the measurement (8 feet) duplicates actual installation. The installation manual has been modified to specify the exact installation procedure, including length of the cable. Please see the revised manual. The pages of manual revised has been submitted as EXHIBIT 41 through Add Attachment of OET Equipment Authorization Electronic Filing. 2) The recommended antenna specified in the installation instruction is a “thru-glass” antenna which is to be mounted on the rear windshield near the center. Because of the positioning of this antenna, it is not possible for anyone standing in the vicinity of the vehicle to come closer than approximately 3 feet from the antenna. Therefore it was not deemed necessary to measure SAR for a body right next to antenna. 3) Please see the revised manual submitted as EXHIBIT 41.

When it is ON, it receives and also se- nds out radio frequency (RF) signals. In August, 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels • ICNIRP (1996) Those standards were based on comprehensive and periodic evaluations of the relevant scientific literature. For example, over 120 scientists, engineers, and physicians from universities, government health agencies, and industry reviewed the av- ailable body of research to develop the ANSI Standard (C95.1). The design of your phone complies with the FCC guidelines (and those standards). Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the phone and may violate FCC regulations. SAFE PHONE INSTALLATION AND OPERATION For safe and efficient operation, this phone must be properly installed using recommended installation procedure specified in the installation guide for this unit. A "thru-glass" antenna must be mounted on the center of the rear window of the vehicle. At no time should anyone touch the antenna or come in close contact with it while the phone is in operation. Applicant: Shintom Co., Ltd. Transmitter Type: BFYT3017 PAGE 10 OF 52 EXHIBIT 20 ANTENNA CARE WIRELESS MOBILE PHONES READ THIS INFORMATION BEFORE USING YOUR MOBILE CELLULAR TELEPHONE for mobile wireless phones. Those guidelines are consis- tent with the safety standards previously set by both U.S. and International standards bodies: • ANSI C95.1 (1992) • NCRP Report 86 (1986) 4 DRIVING Check the laws and regulations on the use of wireless telephones in the areas where you drive. Always obey them. Also, if using • Use hands-free operation, if available. • Pull off the road and park before making or answering a call if driving conditions so require. ergy. However, RF energy from cellular telephones may af- fect inadequately shielded electronic equipment. RF energy may affect improperly installed or inadequately shielded electronic operating and entertainment systems in motor vehicles. Check with the manufacturer or its repre- sentative to determine if these systems are adequately Consult the manufacturer of any personal medical devices regulations posted in the areas instruct you to do so.
