Exposure to Radio Frequency Signals Your wireless handheld portable telephone is a low power radio transmitter and receiver. When it is on, it receives and also sends out radio frequency (RF) signals. In August 1996, The Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for handheld wireless phones. Those guidelines are consistent with safety standards previously set by both U.S. and international standards bodies: •American National Standards Institute (ANSI) C95.1 1992 •National Council on Radiation Protection and Mea- surement (NCRP) Report 86 1986 •International Commission on Non-Ionizing Radia- tion Protection (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 available body of research to develop the ANSI Standard(C95.1). The design of your phone complies with the FCC guidelines (and those standards). Welcome v Safety Information (Continued) Antenna Care Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the phone and may violate FCC regulations. Phone Operation Normal Operation Hold the phone as you would any other telephone with the antenna pointed up and over your shoulder. Tips on Efficient Operation For your phone to operate most efficiently: •Extend your antenna fully. •Do not touch the antenna unnecessarily when the phone is in use. Contact with the antenna affects call quality and may cause the phone to operate at a higher power level than otherwise needed. Batteries Caution: All batteries can cause property damage, injury, or burns if a conductive material, such as jewelry, keys, or beaded chains, touches exposed terminals.The material may complete an electrical circuit and become quite hot. To protect against such unwanted current drain, exercise care in handling any charged battery, particularly when it is inside your pocket, purse, or other container with metal objects.When the battery is detached from the phone, your batteries are packed with a protective battery cover; please use this cover for storing your batteries when not in use. vi Welcome Safety Information (Continued) Driving Check the laws and regulations on the use of wireless telephones in the areas where your drive. Always obey them. Also, if using your phone while driving, please: •Give full attention to driving--driving safely is your first responsibility. •Use hands-free operation, if available. •Pull off the road and park before making or answer- ing a call if driving conditions so require. Electronic Devices Most modern electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded against the RF signals from your wireless phone. Pacemakers The Health Industry Manufacturers Association recommends that a minimum separation of six (6") inches be maintained between a handheld wireless phone and a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with the independent research by and recommendations of Wireless Technology Research. Persons with pa…

October 6, 1998 RE: Form 731 Confirmation Number: EA89999 FCC ID: IHDT5YA1 Frank, From discussion during the processing of another recent application, we now understand that the Lab has determined that ERP referenced to a Dipole should be used for 800 MHz Cellular products under Rule Part 22(H), when the product is provided with an integral antenna and without a 'standard' RF connector. The stated ERP of 0.7 Watts for this product was measured in Analog mode and was based on a conducted output power setting of 0.55 Watts. In addition, this ERP measurement was with reference to an Isotropic radiator. The nominal conducted output power setting for this product, as it ships, will be 0.5 Watts (and this was the setting used in the SAR evaluations). Adjusting from 0.55 Watts to 0.5 Watts (i.e. dividing by 1.1) and further adjusting for the difference in 'gain' between a dipole and 'isotropic' (i.e. dividing by 1.64), the RATED ERP (with respect to a dipole) for this product should be 0.39 Watts (for the Analog mode Emission Designators, 40K0F1D and 40K0F8W). The 'in the burst' power for the TDMA mode (Emission Designator 30K0DXW) uses the same power control settings as for the Analog modes. This yields an 'in the burst' conducted power output of 0.5 Watts and, therefore, is also requested to be listed as 0.39 Watts. We also request that the Grant Form identify that the Output Powers listed are 'Effective Radiated Power.' I trust that the additional submitted reports and this correspondence will satisfy all further questions regarding SAR measurement and allow the GRANT of this Equipment Authorization.

Standards used on measurements supplied are EIA IS-137 and OET 53. 4.Similar to "Currently Type Accepted Transmitter Type(s)" IHDT5WT1 5.Report of measurements pertaining to types of emission, frequency range, maximum output power and modulation techniques for Digital Mode Operation (per paragraphs 31 and 32 of the Report and Order in FCC GEN. Docket No. 87-390). A.Types of emission This equipment continues to be capable of the existing, approved emissions for previously existing equipment designed and approved for operation in the Domestic Public Cellular Radio Telecommunications Service in the Analog Mode and Digital Mode. Reference is also made to EIA/TIA Interim Standard IS-137. Actual measurements of Occupied Bandwidth for the Digital Mode are shown in Exhibit 9F-5. Spurious Emissions (Conducted and Radiated) are reported in Exhibits 9G and 9H are the worst (highest level) of Digital and Analog Modes. B. Frequency range The frequency range of the equipment is the Domestic Public Cellular Radio Telecommunications Service bands, 824 - 849 MHz and 869 -894MHz, regardless of whether in Analog or Digital mode. Frequency Stability versus Temperature and Voltage measurements are shown in Exhibits 9J-1 & 2 and 9K-1 & 2. This equipment uses Automatic Frequency Control (AFC) to lock to within ±200 Hz of the received frequency from the Land Station system. Also refer to Exhibit 6A. C. Maximum output power Radio Frequency Output Power is 0.6 Watts. Power output capability of the Mobile Station equipment is still reported to the Land Station system (via the Mobile Station Power Class in the Station Class Mark) and the Mobile Station will respond to commands from the Land Station system to change power levels as defined in the specifications. R. F. Output Power measurement results are shown in Exhibit 9A. D. Modulation techniques Modulation in the Digital Mode is p/4 DQPSK (Differential Quaternary Phase Shift Keying). Reference is made to the EIA IS-137 for further details. Exhibits 6C and 6D further discuss details of the modulating circuitry. Exhibit 6F discusses digital modulation techniques. Exhibits 9B, 9C, 9D, 9E-1 & 2 and 9F-1 to 6 show the results of modulation related testing. APPLICANT: MOTOROLA, INC.FCC ID: IHDT5YA1 EXHIBIT 2 6.Determination of Emission Designator for Digital (TDMA) Operation (per Part 2 - Subpart C of the commission's rules) A. Emission, modulation and transmission characteristics (per section 2.201) a. First Symbol - Type of modulation of the main carrier. The main carrier is p/4-shifted Differential Quaternary Phase Shift Keyed (p/4-DQPSK), which has both amplitude and angle modulation characteristics, during the digital mode of operation. This corresponds to the symbol D, defined as “Emissions in which the main carrier is amplitude and angle-modulated either simultaneously or in a pre-established sequence.” b. Second Symbol - nature of signal(s) modulating the main carrier. One Digital Signal representing sampled quantized voice or other audio information or command data modulates the main carrier in a time division multiplex fashion during the digital mode of operation. This corresponds to symbol X, defined as “Cases not otherwise covered.” The symbol 1 excludes time-division multiplex, and the other choices for digital modulating signals either state “Two or more channels containing quantized or digital information” or “Composite system with one or more channels containing quantized or digital information, together with one or more channels containing analogue information.” c. Third symbol - Type of information to be transmitted. The information transmitted in the digital mode of operation is a combination of data transmission (command data) and telephony (sampled quantized voice or other audio signals). This corresponds to symbol W, defined as “combination of above” which would be the combination of symbol D, “Data transmission, telemetry, telecommand,” and symbol E, “Telephony (including sound broadcasting).” B. Bandwidths (per section 2.202) Bandwidth is primarily determined by the square root of raised cosine filter used to filter the modulating signals. Per EIA IS-137, the filter is defined to have a one sided 3-dB bandwidth of 12.15 kHz with the slope of the roll off defined by alpha = 0.35. The radio in the digital mode is intended to operate in the TDMA mode. Power ramp up and ramp down times as defined in EIA IS-137 are 124.8 microseconds or less. Computer simulations show that any power transmitted beyond ± 15 kHz of the carrier is 50 dB below the carrier or less for the ramp up and ramp down characteristics used in the radio. Based on these considerations, the bandwidth used is 30 kHz. Converting this result to the format indicated in paragraph 2.202(b), yields 30K0. The resulting complete emission designator for the digit operation is then 30K0DXW. The current Emission Designators for the conventional analog mode, 40K0F1D and 40K0F8W, are included since the equipment also operates in the conventional analog mode.

Introduction The Motorola Personal Communications Sector Product Safety Laboratory has performed measurements of the maximum potential exposure to the user of portable cellular phone FCC ID IHDT5YA1. The Specific Absorption Rate (SAR) of this product was measured. This report details the test setup and equipment as well as the results of those tests. 2. Applicable Regulations Federal Communications Commission rule §2.1093(d)(2), the ANSI/IEEE C95.1 1992 and the NCRP Report Number 86 specify the maximum exposure limit of 1.6 W/kg as averaged over any 1 gram of tissue for portable devices being used within 20cm of the user in the uncontrolled environment. 3. Description of Test Sample A prototype unit serial number DFF901BC was measured. This unit is identical in physical construction, maximum radiated power levels and antenna structure to units that will be in production. It transmits in the frequency range of 824 to 849 MHz using AMPS, NAMPS and TDMA modes. The maximum average transmit power for this test unit is 0.5 Watt in analog modes, and 0.17 Watt (average) / 0.5 Watt (peak) in digital mode. The unit is equipped with a telescoping antenna that serves as both a receive and transmit antenna. The antenna has a retracted and an extended operating position as shown in figures 1 and 2 respectively. Figure 1.Figure 2. P P a a g g e e 3 3 Figures 3 and 4 show the test unit as it is placed onto the phantom head with the antenna in the extended and retracted positions respectively. For the purposes of the actual SAR tests the phantom head is tilted on its side by 90 degrees so that a vertically oriented measurement probe can easily scan an area where the phone is in close contact with the phantom and the SAR will be the highest. Figure 3. P P a a g g e e 4 4 Figure 4. 4. SAR Test Facility The Motorola test facility utilized for the SAR testing of this product is the Personal Communications Sector Product Safety Laboratory, in Libertyville Illinois. The laboratory utilizes an SAR measurement system developed by Motorola and manufactured by IDX Robotics™ of Corvallis, Oregon. This system utilizes a computer controlled six axis robot to move a measurement probe to measure the SAR. The probe is calibrated at the Florida Corporate Electromagnetics Laboratory in Plantation Florida, using a procedure developed by Dr. Q. Balzano. The measurement methodology is described in IEEE Transactions on Vehicular Technology, vol. 44, no. 3, August 1995, titled Electromagnetic Energy Exposure of Simulated users of Portable Cellular Telephones. Furthermore, a copy of the document “SAR Measurement Operational Guide”, dated December 1997, is attached as appendix B for reference purposes. This Motorola document describes the measurement setup and rationale in detail. P P a a g g e e 5 5 5. Test Sample Conditions For the purposes of these tests the subject phone was positioned on the measurement phantom per the instructions in the Motorola users manual for the subject phone. SAR was measured with the antenna in both the retracted and extended positions. Since the antenna is not located on the center of the phone, the SAR was measured with the phone on both the left and right side talk positions (See figures 3 and 4). Due to the construction of the phone, the base of the antenna is 23 mm away from the cheek of the phantom in all cases. The test sample is capable of operation in a test mode that allows control of the transmitter without the need to place actual phone calls. This guarantees that the unit does not change its transmitter power, and that the resultant SAR values will not be affected by external connections. For the purposes of this test the unit is commanded to test mode and manually set to the proper channel, transmitter power level and transmit mode of operation. The phone is then placed in the SAR measurement system with a fully charged battery. At the end of each test the unit is measured for RF power out so as to ensure that the test was evaluating the maximum SAR level. For the purposes of these tests, the transmitter was operated at the highest transmitter output level in both the analog and digital modes, with the antenna in both the extended and retracted positions, and with the phone on both left and right side talk positions. 6. Method of Measurement For each antenna position the system is instructed to scan as much of the face of the phone as is in close proximity to the phantom. Using the information gained about the general region of highest SAR, the system then automatically scans a smaller area centered around the location of peak spatial SAR. Once the precise location of highest SAR is found, the system then automatically measures the fall off of electric field strength as the measurement probe is moved away from the inner surface of the phantom in the direction of the local normal to the phantom surface. Using appropriate probe calibration techniques, the SAR in 1 gram of phantom tissue is then calculated. The phantom head shown in figures 3 and 4, was filled with a liquid having relative dielectric constant equal to 40 and conductivity equal to 0.85 S/m. This mixture is a good dielectric equivalent of the gray matter of the human brain. The composition of the liquid mixture is as follows: 42.5% water; 55.6% sugar; 0.8% salt, 1% HEC; and 0.1% bactericide. 7. SAR Test Results Figure 5 shows the phone overlaid with a typical contour plot. Also shown are cross …

To: Kwok Chan, FCC cc: John Kalenowsky, Motorola, Inc. From: Paul Moller, Motorola, Inc. Subject: FCC ID IHDT5YA1 hand SAR Date: September 29, 1998 Portable cellular phone FCC ID IHDT5YA1 was measured for total radiated power in the presence of a human phantom complete with a hand holding the phone. The phone was positioned on a full body measurement phantom per the instructions in the Motorola users manual for the subject phone. Total radiated power was measured without a hand holding the phone, and then as a second measurement with a phantom hand holding the phone in a normal position. One can see the placement of the phantom hand relative to the subject phone in picture A. The phantom hand has the same dimensions as a real human hand, and is made of a pliable shell that is filled with tissue simulant. The tissue simulant is the same as is used in the head phantom. The dielectric constant is 40 and the conductivity is 0.85 S/m. The phantom is placed inside of an anechoic chamber capable of performing full spherical scans of the phones radiation characteristics, specifically total radiated power. The difference in total radiated with and without the phantom hand is then measured for both the antenna retracted and extended cases. This difference in total radiated power is then the maximum power that is deposited in the hand. The phone was set to transmit on maximum power (0.5 Watt) in analog mode. Since digital mode average transmit power (0.17 Watt) is less than the analog power, total radiated power was not measured in digital mode. For the subject phone, the maximum power deposited in the hand was found to be less than 10mW for both the antenna retracted and extended positions. These results were measured on channel 991 which is the same channel as had the maximum SAR in the head phantom. Federal Communications Commission rule §2.1093(d)(2), the ANSI/IEEE C95.1 1992 and the NCRP Report Number 86 specify the maximum exposure limit in the hand of 4 W/kg as averaged over any 10 grams of tissue for portable devices being used within 20cm of the user in the uncontrolled environment. More than 40mW of total power deposited in the hand would be required for the limit of 4 W/kg averaged over 10 grams to be exceeded. Since the total power deposited in the hand for the test phone is less than 40mW, the standard is not exceeded. Included are two pictures. Picture A shows the subject phone in the normal talk position with the phantom hand in the test position. Picture B shows the full body phantom in the anechoic chamber.
