Section 2 MAINTENANCE 1.0 Introduction This chapter provides details about the following 2.0 • Preventive maintenance (inspection and cleaning). • Safe handling of CMOS and LDMOS devices. • Repair procedures and techniques Preventive Maintenance Periodic visual inspection and cleaning is recommended. 2.1 Inspection Check that the external surfaces of the radio are clean, and that all external controls and switches are functional.
2-2 Preventive Maintenance solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices. Cleaning Internal Circuit Boards and Components Isopropyl alcohol (100%) may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away from the inside of the radio.
Preventive Maintenance 2-3 DO NOT attempt to disassemble the radio without first referring to the following CAUTION statement. ! Caution This radio contains static-sensitive devices. Do not open the radio unless you are properly grounded. Take the following precautions when working on this unit: • Store and transport all CMOS devices in conductive material so that all exposed leads are shorted together.
2-4 3.0 Repair Procedures and Techniques — General Repair Procedures and Techniques — General NOTE Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit boards — examples shown below) were developed and assembled using environmentally preferred components and solder assembly techniques to comply with the European Union’s Restriction of Hazardous Substances (ROHS) Directive 2002/95/EC and Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC.

Section 4 POWER UP SELF-TEST 1.0 Power-Up Error Codes (Display Model only) Upon powering up, the radio performs certain tests to determine if its basic electronics and software are in working order. Any error detected has an associated error code that is presented on the radio display. These error codes are intended to be used by a service technician when the radio generates the Self Test Fail Tone. If these tests are successfully completed, the radio will generate the Self Test Tone.

Section 5 CONTROLLER INFORMATION 1.0 General Controller Block The controller board is the central interface between the various subsystems of the radio. The controller section consists of 4 main ICs. These are the OMAP1710 Host/DSP Processor, Flash, DDR RAM memories and the MAKO Audio/Power Management chip. Figure 5-1 shows how the controller interfaces with the RF Section and the supporting controls, switches and display.
5-2 Controller Board The OMAP processor controls the operation of the transmitter, receiver, synthesizer and MAKO IC. It also uses Flash and DDR RAM, both located externally. 1.2 Flash Memory (U2000) The Flash memory IC is a 64Mbit CMOS device. It is supplied with 1.8V. The Flash memory has its 25 address lines and 16 data lines connected to the External Interface Module (EIM) of the OMAP IC through the EMIFS_ADDR(25:1) and EMIFS_DATA(15:0) busses.
Controller Board 5-3 Figure 5-2 illustrates the DC distribution to various ICs and devices in the radio. The power management architecture is centered on the MAKO IC (U3000). A battery supply is routed via a 3A fuse (F9000) which goes directly to the electronic ON/OFF control (PMOS power FET Q3003) as RAWB+. When the radio is turned ON, MECH_SW (ON/OFF/volume control) will trigger the MAKO FET_ENX to low thus turning ON the PMOSFET device, and SWB+ is then distributed as shown in Figure 5-2.
5-4 Controller Board 2.1.2 Power ON/OFF The radio can be switched ON in only one condition: 1. MECH_SW turned ON Turning the rotary switch (S9001) ON will cause MAKO (U3000) to turn ON SWB+. After application of power to SWB+, MAKO regulators are sequenced to turn ON power to all MAKO internal blocks and external system including OMAP processor (U1000), FLASH (U2000), SDRAM (U2001), and radio RF section. Radio can be turned OFF in one of the three conditions: 1.
Controller Board 5-5 The OMAP processor (U1000), which consists of an ARM and DSP core, needs three clocks for operation: a 32.768kHz square-wave, a 12MHz sine-wave, and a 16.8MHz square-wave clock. The 16.8MHz clock source is provided from the Trident TCXO routes to a squarer-circuit (U1006) and feed to EXT_CLK (U1000 pin N18). The 32.768kHz clock is generated by the MAKO crystal (Y3000) oscillator, converted to a gated clock by U3003 and U3004 circuitry.
5-6 Controller Board The HPD SPI is a synchronous serial bus made up of four lines, SPI_CLK, SPI_MOSI, SPI_MISO, and chip select. The SPI_CLK line is used to control the speed of the data to/from the peripheral IC’s and the OMAP processor. This clock can be adjusted to different speed based on the IC’s specification. HPD SPI module is used to interface to Trident (U001), Abacus III (U600), and the MAKO (U3000). This interface operates at 1.875V logic level.
Controller Board 2.5 5-7 ACC_ID Interface Smart accessories use the Accessory ID (ACC_ID) Interface to help the radio determine which smart accessory, if any, are attached to the radio. Figure 5-6 illustrate the ACC_ID connections used within the radio. 5V 2.9V 1.875V 2.9V 5V R3300 R3304 R3031 Vref1 MAKO U3000 OMAP1710 U1000 ACC_ID (P9) HDQ (N20) Vref2 SCL1 SCL2 SDA1 SDA2 ACC_ID_UP (L7) 2-BitTranslator U3009 Figure 5-6: ACC_ID Interface Connections 2.
5-8 Controller Board In the portable radio, only one of the two MAKO USB transceivers is used to provide the physical layer signaling for the USB port. The transceiver generates and receives the DP and DM differential signals of the port. The MAKO transceiver interfaces to the OMAP processor through a three-wire interface consisting of two bi-directional signals (SE0 and DAT), and one uni-directional signal (TXEN).
Controller Board 2.10 5-9 Audio V02_O(1.875V) for OMAP V06(2.9V) for Patriot MIC BIAS MIC BIAS L OGIC_VDD The audio circuitry consists of both analog and digital audio paths. Figure 5-8 shows the basic block diagram of the audio interconnections.

5-10 Controller Board 2.10.2 Transmit Audio Transmit audio can be sourced from either internal or external microphone path. Both the internal and external microphone carries a 5V bias through a resistor to MAKO MIC_BIAS pin. The MAKO, through SPI, selects the appropriate microphone path to route to the necessary gain stages and converter that will send 16-bit PCM audio to the OMAP for signal processing via the SSI bus.

After mixing with the first LO signal from the voltage control oscillator (VCO) using high side injection (for 800MHz) or low side injection (for 900MHz), the RF signal is down converted to the 73.35 MHz IF signal. The 50 Ohm matching for the mixer at the LO input port is provided by C431 and L414.

Glossary This glossary contains an alphabetical listing of terms and their definitions that are applicable to portable and mobile subscriber radio products. All terms do not necessarily apply to all radios, and some terms are merely generic in nature. Term Definition Analog Refers to a continuously variable signal or a circuit or device designed to handle such signals. Band Frequencies allowed for a specific purpose.
G-2 Term Definition MHz Megahertz: One million cycles per second. Used especially as a radiofrequency unit. Paging One-way communication that alerts the receiver to retrieve a message. PC Board Printed Circuit Board. Also referred to as a PCB. PL Private-Line Tone Squelch: A continuous sub-audible tone that is transmitted along with the carrier. Programming Cable A cable that allows the CPS to communicate directly with the radio using USB. Receiver Electronic device that amplifies RF signals.
