Battery Type Detection Memory circuit consists of the ASIC (IC10) and the The transceiver automatically detects the battery type, SRAM (IC4), the fl ash memory (IC1). The fl ash memory has measuring the resistance between the S-terminal and GND capacity of 32M-bit that contains the transceiver control terminal on the battery pack and changes the supplied volt- program for the ASIC and stores the data.

Encode (QT/DQT/DTMF/2TONE /MSK) Each signaling data signal of QT, DQT, DTMF, 2TONE and MSK is generated by the DSP circuit, superposed on a mod- ulation signal and output from IC10. The modulation balance of the QT/DQT signal is adjusted by the D/A converter (IC502) and the resulting signal is routed to the modulation input of the VCO and VCXO (X301).
