Connector J1, the B-plus assembly, connects the battery to the transceiver board. Capacitors C1, C2, and C3 provide protection against momentary breaks at the B-plus connector due to contact bounce when the radio is dropped.

    Radio Power: DC Power Routing—VOCON Board Transistor Q501 is also under the control of the microcontroller unit (MCU) via Vref from U501. This allows the MCU to follow an orderly power-down sequence when it senses that B+SENSE is off. This sense is provided through MECH_SW_BAR (inverted B+SENSE, see Q508).

  • Page 35: Chapter 4 Troubleshooting Procedures

    Chapter 4 Troubleshooting Procedures The purpose of this chapter is to aid in troubleshooting problems with the ASTRO XTS 5000 radio. It is intended to be detailed enough to localize the malfunctioning circuit and isolate the defective component. It also contains a listing of service tools recommended for PC board repair at the component level.
