    BR200DV/BR300DV Service Manual Chapter 4 Disassembly For Repair The radio is a kind of sophisticated communication equipment with small and fine mechanical structure. You should assemble and disassemble it carefully during the maintenance process. The Instruction for assembly and disassembly are as follows:...
  • Page 14 BR200DV/BR300DV Service Manual * Do not disassemble the battery case. Installing/Removing Antenna, Channel Selector, Power/Volume Knob Screw the antenna out of the connector at the top of the radio by holding the bottom of the antenna and turn it counter clockwise until apart.
  • Page 15 BR200DV/BR300DV Service Manual Installing/Removing the Belt Clip Use the 2 screws (M2.5x8.0) supplied with the radio and fix these screws on the holes in the radio clip and into the holes in the aluminum case. If you want to remove the clip from the radio, just unscrew them, and remove the clip, you can put the screws back to make sure you do not loose them.

  • Page 22: Chapter 5 Circuit Description

    BR200DV/BR300DV Service Manual Chapter 5 Circuit Description 5.1 Frequency configuration The reference frequency of frequency synthesizer is provided by 16.8MHz crystal oscillator X1 TCXO. The receiver adopts quadric mixing mode. The first IF is 49.95MHz, and the second IF is 450kHz. The first local oscillation signal of the receiver is produced by frequency synthesizer and the second local harmonics of 16.8MHz of crystal oscillator X1 TCXO.
  • Page 23 BR200DV/BR300DV Service Manual Signals from LNA are filtered again by BPF before entering the 1st mixer (Q202). The PWM wave is output by MCU composed of 58 foot and then commutated to adjustable voltage after filtering to change the capacity of varactor diode D905 D203 D202 and D204 to control the center frequency of BPF.
  • Page 24 BR200DV/BR300DV Service Manual Receiving Audio Signal Processing: The audio processing circuit of receiver consists of IC300. Voice signals from IC300 are sent to IC301 （CTCSS signaling filter circuit. Squelch Circuit Part of the AF signal from the IC200 enters the FM IC again,and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.
  • Page 25 BR200DV/BR300DV Service Manual Gate bias of Q105 and Q107 is controlled by APC circuit, so the output power of transmitter can be controlled conveniently by changing the gate bias voltage. APC（Automatic Power Control） Figure 5 Schematic Diagram for APC Circuit R130 R131 and R132 are power amplification current detector, IC100A is power amplification current sampling amplifier and IC00B is power comparison amplifier.
  • Page 26 BR200DV/BR300DV Service Manual distortion in case of oversized MIC signal. Q601, the power switch of voice processing circuit, controlled by MCU, will give power supply to IC601 only during transmission. J501 is the socket for external MIC, and the internal MIC will disconnect automatically when using external MIC, but the internal PTT is still effective.
  • Page 27 BR200DV/BR300DV Service Manual Lock lost detection: When PLL is out of lock, IC pin4 will output low level signal to MCU， and then MCU prohibit transmitter from transmitting with a warning tone. Q8, the power filter, can provide PLL with more purified power to reduce the noise of frequency synthesizer.
