5 SOFTWARE: ENHANCING OPERATING PLEASURE

TS-590S CONTENTS 43

Though only two PF keys are available on the transceiver, it is possible to increase the number of the

PF keys by using a switch to switch a voltage derived from the microphone connector.

If you have a microphone equipped with the PF keys such as MC-47 (although it was discontinued

and no longer available), you can assign the PF function to the PF key and the UP and DOWN keys.

Likewise, by adding an external circuit as shown below, the PF function also can be assigned.

Figure 5-6 Example of Circuit

Caution:

 The figure shows the microphone connector viewed from the front panel, but it is inverted (upside down).

 The circuit only shows the connection of DC signals. Be fully aware of loop interference of radio frequency signals and other

possible issues that may arise.

 We will not accept any request for fixing problems arising from connecting devices other than Kenwood’s genuine optional

products regardless of the content of this document.
