    TK-3000 REALIGNMENT Note: 1. Modes • The data stored in the personal computer must match Model Name and Model Type when it is written into EE- User mode PROM. • Do not press the [PTT] key during data transmission or PC mode Data programming mode reception.
  • Page 5 TK-3000 REALIGNMENT 3-6. Programming with PC If data is transferred to the transceiver from a PC with the FPU, the data for each set can be modifi ed. Data can be programmed into the EEPROM in RS-232C format via the SP/MIC jack. In this mode the PTT line operate as TXD and RXD data lines respectively.
