Operation
The TK-260/(N) transceiver operates in several modes: User Mode, PC Mode, Clone Mode, and Manufacture Mode.
– User Mode is for normal operation.
– PC Mode allows various settings through the FPU via the RS-232C port.
– Clone Mode is used to copy data settings from another transceiver using an interface cable.
– Manufacture Mode is for realigning settings through the RS-232C port during manufacturing.
To enter each mode:
– User Mode: Power ON.
– PC Mode: Connect to an IBM PC compatible machine and control with the FPU.
– Clone Mode: Receive clone data from a transceiver attached to the TK-270/(N)/278/(N)/T with an interface cable.
Key functions include:
– CH: Channel switching (4ch).
– PTT: Transmit switch (push-to-talk).
– MONI: Monitor or Squelch control ON/OFF.
– POWER/VOL: ON/OFF switch and volume control.
– LED: Indicates transmission status and battery pack voltage.
The PC Mode requires connecting the TK-260/(N) to a personal computer with an interface cable. The programming software can be used with an IBM PC or compatible. Data can be programmed into the E27PROM in RS-232C format via the SP MIC plug.
In Clone Mode, two transceivers are connected, and the contents of the E7PROM are transferred using the optional KCT-8 interface cable.
