PREFACE The iDEN i870 Digital Multi-Service, Data-Capable Portable Field Service Manual contains the information necessary to identify and fix problems in the Motorola i870 Digital Portable. This unit is based on digital technology and is designed to operate on iDEN systems. Basic and field-level service for the this unit as described in this manual includes troubleshooting, testing, board swapping, and maintenance.
PREFACE: Conventions Used in This Manual 1.3 Conventions Used in This Manual The following conventions are used throughout this manual: italics bold code 1.
CHAPTER 1 OVERVIEW To achieve a high spectrum efficiency, the i870 digital multi-service, data-capable portable uses a unique modulation technology and sophisticated voice-compression algorithm. The voice of the person speaking into the microphone is converted into a digital bit stream consisting of zeros (0) and ones (1). The stream then is modulated into a radio-frequency (RF) signal, which is transmitted over the air to another unit. This process is called digital modulation. 1.
OVERVIEW: iDEN Digital Modulation Technology RL 0dBm 10 dB/ -10 -20 -30 Power -40 (dB) -50 -60 -70 -20 -10 0 10 20 Frequency from Desired Channel Center (kHz) Figure 1-1. Spectrum of iDEN Quad 16QAM Quadrature Phase Shift Keying (QPSK) is one of the most common modulation techniques for satellite communications. In QPSK, a digital data stream is taken two bits at a time to generate four possible phase states of the transmitted carrier. A characteristic of this technique is its resistance to noise.
OVERVIEW: iDEN Voice Compression Technology algorithms and one digital-signal processor (DSP) to perform voice compression/decompression and RF modulation/demodulation. Base Station Control Channel Transmitting 6 of 6 slots continually.
OVERVIEW: iDEN Voice Compression Technology (GPS) system. Each burst is numbered; the number is referred to as the slot number. All bursts occurring at a given time carry the same slot number. Inbound transmission bursts (sent from the unit) are offset 19 milliseconds from the outbound burst; the inbound burst begins 4 milliseconds after the end of the outbound burst (see Figure 1-2 on page 1-3).
OVERVIEW: Global Positioning System (GPS) Section 1.3 Global Positioning System (GPS) Section The U.S. Department of Defense (DoD) has built a 24-satellite constellation for the purpose of pinpointing locations anywhere on the planet. The satellites circle the earth every 12 hours, transmitting radio signals at a fixed frequency of 1575.42 MHz. The satellites share the 1575.42 MHz spectrum with each other through the use of CDMA modulation.
OVERVIEW: SIM Cards 1.6 SIM Cards This unit is designed to work with a mini Subscriber Identity Module (SIM). The SIM card contains all of the personal data required to access iDEN services. Data held by the SIM card includes: • • • • Temporary Mobile Subscriber Identity Services to which the user subscribes PIN and unblocking codes Call barring codes The SIM card is also capable of storing phone numbers and names. Available SIM cards for this unit are 64 kB and prepaid. 1.6.
OVERVIEW: SIM Cards Figure 1-3. Removing a SIM Card Figure 1-4. Inserting a SIM Card To insert a SIM card (Figure 1-4): 1. Open the SIM card holder. 2. Carefully slide the SIM card into the holder (see Figure 1-4). Position SIM card as shown. 3. Close SIM door, slide latch to shut. 4. Reinstall the battery, and reattach the battery cover.

The default values for these parameters are as follows: 8.
FIELD LEVEL TEST MODES AND PROCEDURES: Field-Level Test Checklist 8.3 Field-Level Test Checklist Use the following test checklist to ensure that all the necessary tests are performed and to provide a tracking mechanism in case the unit is sent to the next level of service. Check the appropriate box for each test performed and indicate whether or not the test was completed successfully. Table 8-1.
FIELD LEVEL TEST MODES AND PROCEDURES: Registration/Call Test 8.4 Registration/Call Test Use this test on a unit having any of the following symptoms: No Service failures, Please Wait... Registering failures. (Use a reference unit to get a baseline.) Note: For 900 MHz verification, please perform the BER Test. May require ordering additional option for test. Contact Motorola Customer Service (see Appendix A). Set up the R-2660 for iDEN Mobile operation, and connect the unit to the RF IN/OUT connector.
FIELD LEVEL TEST MODES AND PROCEDURES: Signal Quality Error (SQE) Test 8.5 Signal Quality Error (SQE) Test Use this test on a unit having any of the following symptoms: No service failures or poor SQE/ RSSI (poor performance in known good coverage area). Set up the R-2660 for iDEN Mobile operation, and connect the unit to the RF IN/OUT connector. See Figure 7-1 on page 7-3. Connect the regulated battery eliminator to the unit to be tested. Remove the antenna from the unit. Set the power supply 4.0 Vdc.

Set up the R-2660 for iDEN Mobile operation, and connect the unit to the RF IN/OUT connector. Place an interconnect call. (See Registration/Call test.) Notes: 1. Verify that the unit can pass the SQE test before performing the Audio test. 2. This test checks outbound interconnect signals using the earpiece. Fail Perform Registration/Call troubleshooting procedure.
FIELD LEVEL TEST MODES AND PROCEDURES: Reset Test 8.11 Reset Test Use this test on a unit having any of the following symptoms: unit resets, or unit powers off and then on. Set up the R-2660 for iDEN Mobile operation, and connect the unit to the RF IN/OUT connector. Power up the unit. Enter Initial Registration mode (see Operating the R-2660). Notes: 1. Verify that the unit has resets entries in the Reset log. See the Reset Log Test. 2. Try to duplicate the failure. 3.
FIELD LEVEL TEST MODES AND PROCEDURES: Reset Log Test 8.12 Reset Log Test Use this test to check the reset log in the unit. To perform the reset log test: 1. Power on the unit and wait until registration is complete. 2. If the unit does not have the latest software version, reflash (reprogram) the unit. If the unit attempts to reset, perform the Reset test (see page 8-11). 3. Enter Trace Mode (see page 6-1). The Unit Info display appears. 4.
FIELD LEVEL TEST MODES AND PROCEDURES: Model Assembly (MA) Test Mode Test 8.
FIELD LEVEL TEST MODES AND PROCEDURES: GPS (Global Positioning System) Receiver Test 8.14 GPS (Global Positioning System) Receiver Test Use this test on a unit to check its GPS functionality. Find an open sky area. Extend antenna and power up unit. Obtain reference GPS receiver. Activate GPS Phone returns location coordinates ? Yes Location coordinates match reference ? Yes GPS working. No No GPS not working.
FIELD LEVEL TEST MODES AND PROCEDURES: Bluetooth Test 8.15 Bluetooth Test Use this test on a unit to check the functionality of the Bluetooth Headset. Obtain Motorola HS810 or HS820 Bluetooth Headset. Extend antenna and power up unit. Turn unit on. Bond with Bluetooth headset. Successful bond ? Yes Make phone call with Bluetooth headset Successful call ? Yes No No Bluetooth not working * Bluetooth is working.
FIELD LEVEL TEST MODES AND PROCEDURES: i870 Camera Test 8.16 i870 Camera Test Use this test to check camera module. Symptoms: Bad view finder (noise, poor color, synchronization error). Power up the unit. Enter the Model Assembly (MA) Test Mode. Verify that the viewfinder shows the captured image correctly. Pass Fail Replace Flip Assembly and repeat the test. Fail Pass Replace the main FPC and repeat the test. Fail Pass Unit passed test.
FIELD LEVEL TEST MODES AND PROCEDURES: MOTOtalk Test 8.17 MOTOtalk Test Perform BER Test and TX Power Test prior to the MOTOtalk Test. If these tests do not pass, replace the Main Board. Use the MOTOtalk Test to test MOTOtalk without test equipment. Perform the MOTOtalk Test with the golden radio as transmitter, determine pass or fail. Then, use the golden radio as receiver and determine pass or fail. Place radio under test and a golden radio into MOTOtalk Mode: 1. Menu 2. More 3. Down 4. Down 5.
