  • Page 7: Warranty Service Policy

    Product Support Customer’s original units will be repaired but not refurbished as standard. Appoint- ed Motorola Service Hubs will perform warranty and non-warranty field service for level 2 (assemblies) and level 3 (limited PCB component). The Motorola Hi-Tech Centers will perform level 4 (full component) repairs.

  • Page 8: Parts Replacement

    When ordering crystals or channel elements, specify the Motorola part number, description, crystal frequency, and operating frequency desired. When the Motorola part number of a component is not known, use the product model number or other related major assembly along with a description of the related major assembly and of the component in question.

  • Page 9: Circuit Description

    Communication with accessories is through the CE bus connector through the audio/power controller IC. Audio through the external connector is analog. The V200 has an integrated speakerphone that also serves as the alert transduc- er. The audio/power controller IC handles all the audio functions including alert/ speakerphone and headset speaker/microphone.

    Level 3 Service Manual Circuit Description Transceiver (RF Circuit) The V200 transceiver chip set includes Motorola front-end (FE), mixer/exciter (ME), and RF transceiver ICs. Refer to Figure 1. Switching between the antenna and accessory antenna port is mechanical, having a normally-closed circuit with the antenna connector. When an accessory RF plug is inserted, the switch opens the antenna circuit and closes the accessory port circuit.

V200 controller block diagram Transmit Audio from the internal speakerphone microphone or headset microphone is routed through, and amplified by, audio/power controller IC U1200. From U1200, the transmit audio is sent to call processor IC U1100 on the MIC1 and MICREF lines.

  • Page 15 Level 3 Service Manual Circuit Description Memory Interface The call processor IC U1100 has access, via its parallel data bus, to 1 SRAM (256k X 16) U1400 in a 48-ball uBGA and 1 32 Mbit (2 Mbit x 16) Read-While-Write capable burst flash EPROM U1300 in a 56-ball uBGA/FBGA (this part combines EEPROM and Flash ROM functionality).
  • Page 16 TEMP_SENSE Input to the measurement ADC from thermistor. CE Bus Connector V200 Personal Communicators have the Motorola CE Bus interface. The bus incorporates RS232 serial communication and universal serial bus (USB) into one connector. The CE Bus supports connection to accessories, personal computers, and test systems.

  • Page 17: Transceiver

    RS232 requires a Motorola RS232 data head to interface to a PC. In the V200 CE Bus pin 2 serves the dual functions of BATTFDBK and MANTST. BATTFDBK is used for controlled power dissipation by the charger. MANTST is used to detect the type of charger (Full rate, Mid rate, and Invalid).
