  • Page 18: Circuit Description

    TM-600 Mobile Radio Circuit Description Frequency Configuration The receiver utilizes double conversion superheterodyne. The first IF is 49.95MHz and the second IF is 450KHz. The first local oscillator signal is supplied by the PLL circuit, while the second local oscillator signal (50.4MHz) is generated from the frequency tripling of TCXO (16.8MHz).

  • Page 19: Transmitter Circuit

    TM-600 Mobile Radio 3. IF Amplifier The first IF signal is amplified by Q113 and then enters IC102 (TA31136FN), where the signal is mixed with the second local oscillator signal (50.4MHz) to generate the second IF signal (450KHz). The second IF signal then feeds through a ceramic filter (N: CF202;...

  • Page 20: Pll Circuit

    TM-600 Mobile Radio 2. RF Driver and Final-stage Power Amplifier Circuit The TX-RF signal from Q703 in the VCO circuit is amplified by Q101, Q110 and Q109, and goes to the final-stage amplifier (IC101) for further amplification. Then the amplified signal enters LPF and is transmitted from the antenna.
  • Page 21 TM-600 Mobile Radio Control Circuit The control circuit is composed of CPU, reset IC and power supply control circuit. 1. CPU IC502 (CPU) operates at 9.8304MHz. CPU controls data transmission between E2PROM (IC501), RX circuit, TX circuit, control circuit, display circuit and peripheral circuit.

  • Page 22: Display Circuit

    TM-600 Mobile Radio Vout provides power supply for IC601, IC602 and IC803, which produces 8V, 5V, 3.3V voltage to the circuit. 3. Reset Circuit The reset circuit (also called “Watchdog”) includes a reset IC (CN813LESA) and a peripheral circuit. When a breakdown occurs due to change in external voltage, the CPU would reboot your radio through reset IC automatically.

    TM-600 Mobile Radio Disassembly and Reassembly for Repair Disassembly 1. Power off the radio; then remove the power cable and screw out the antenna connector. 2. Remove the upper cover. 3. Loosen the eight locking screws; then remove the shield cover, and disconnect FFC and speaker connection cable which bind the control board PCB and the main board PCB.
  • Page 113 TM-600 Mobile Radio 5. Pull out the [Volume] Knob, and screw out the copper nut from the potentiometer. Then loosen the four screws locking the front case, and take out the control board PCB. Use an electric iron and a screwdriver to disassemble the antenna connector, power cable, external board and water-proof ring on this board.
  • Page 114 TM-600 Mobile Radio Reassembly For the reassembly of the transceiver, please refer to “Disassembly”. Other procedures are as follows: 1. Fix the bracket (for main unit) by using four self-tapping screws. 2. Screw on four adjustment screws (each with a shrapnel and a shim).
