  • Page 3: Exposure To Radio Frequency Signals

    General Safely Information Exposure to Radio Frequency Signals You 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 . ・ International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996 ・...
  • Page 4 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 car in handing and charged battery, particularly when placing it inside your pocket, purse or other container with metal objects.
  • Page 5 interference. Electronic Devices - Should turn the phone OFF immediately if you have any reason to suspect that interference is taking place. ■ Hearing Aids Some digital wireless phones may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacture to discuss alternatives.
  • Page 6 ■ Potentially Explosive Atmospheres Turn your phone off when in any area with a potentially explosive atmosphere, and obey all signs and instruction. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Areas with a potentially explosive atmosphere are often, but not always, clearly marked.

    Description Cellular System Overview NOTE The following description is intended only as a preliminary general introduction to cellular systems. This description is greatly simplified and does not illustrate the full operation capabilities, techniques, or technology involved in cellular systems.
  • Page 9: Overall Concept

    Overall Concept Cellular systems are used to provide radiotelephone service in the frequency range of 826 – 891 MHz. A cellular system provides higher call handling capacity and system availability than would be possible with conventional radiotelephone systems that require total system area coverage on every operating channel.
  • Page 10 Some of the CDMA benefits are: ■ Improved call quality with better and more consistent sound. ■ Enhanced privacy. ■ Variable rate vocoder. · · CELL B CELL D · · CELL A CELL C · · · · · ·...
  • Page 11 Operation In Figure1: “Hypothetical Cell System”the area bounded by bold lines represents the total coverage area of a cellular system. This area is divided into several cells, each containing a cell site base station which interfaces radiotelephone subscribers to the switching system. Since there are no channels in CDMA, a user has a better chance of completing a call.
  • Page 12 that cell . Since this radiotelephone is dual mode, the radiotelephone can operate in either a CDM system or Analog system.
  • Page 13 Total Customer Satisfaction and over sixty-five years of experience in personal communications mean you can depend upon the quality of this Motorola product. Motorola Digital Cellular Phone is a super-compact, super-light type of the mobile communication terminal devices. It is a cellular communication device that employs the Code Division Multiple Access (CDMA) technology with spectrum efficiency, economy, price competitiveness and high portability.

    Chapter 3. Circuit Description 3-1. Controller ( LOGIC PART ) 1. Oper ation scheme After applying the Battery power (+3.5-4.2V), push the END KEY (POWER KEY), As the high stage is applied to the PWRKEY PIN of AN32201A (IC404), It makes the internal power supply turns on, the power which is generated by the internal Power supply turns on, apply to the MSM6100 CORE (1.867V), MSM6100 PAD and Memory (SDRAM, NAND FLASH).
  • Page 22 ① Microprocessor (ARM926EJ-S) Subsystem The ARM926EJ-S embedded microprocessor supports some features such as : 16KB Instruction and 16KB Data cache, ARM v5TEJ instructions set, Higher performance 5 stage pipeline, Harvard cached architecture. The MSM6100 is designed to dual memory buses separating the memory subsystem from low-speed peripherals such as LCD panels.
  • Page 23 ▶ Receive part The MSM6100 directly controls the RFR6120-1 chipset using the SBI bus and clock of the TCXO using TRK_LO_ADJ. ⑤ UART INTERFACE The MSM6100 provides the UART channel that was conformed by RS-232 interface protocol.
