  • Page 7: Circuit Description

    1. Frequency Configuration The receiver utilizes double conversion. The first IF is 49.95 MHz and the second IF is 450 kHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies.
  • Page 8 TK-2160 6) Tone Volume Fixed Circuit This function generates a TONE signal sound even if the AF volume of the transceiver is the minimum. A TONE signal is sent through Q602 to the AF amplifier when, in the FPU, “TONE Volume Fixed” is set to ON. IC601 AQUA BEEP...

(2) DTMF/2 TONE High-speed data is output from pin 2 of the CPU. The signal passes through a low-pass CR filter, and provides a TX and SP out tone, and is then applied to the audio processor (IC601).

  • Page 11: Installation

    CIRCUIT DESCRIPTION / INSTALLATION 4) Battery Type Detection The transceiver automatically detects the battery type, measuring the resistance between the S-terminal and + terminal on the battery pack and changes the supplied voltage to the S-tarminal as below. The microprocessor then detects the battery type.
