1 PORT FUNCTIONS

This section describes Input/ Output ports of the transceiver.
1.1 8-pin Connector (Mic Connector)
The 8-pin microphone connector is located on the front panel of the TK-7160/ TK-8160. Configuration data can be
written into the transceiver or read from the transceiver by connecting the transceiver to a PC with KPG-99D
software installed.
