INTERFACING TO PERIPHERALS
SP/MIC JACK
The SP/MIC jack on the transceiver can be
configured to interface to various kind of the
peripherals available for the transceiver, such as a
speaker microphone (SMC-32/ 33/ 34), PC interface
cable and a TNC.  Access Menu No. 9 (SP/MIC
JACK) and select the peripheral type from ÒSP/MICÓ,
ÒTNCÓ, and ÒPCÓ.
You can further configure the transceiver to interface
to a high speed (9600 bps) TNC that requires a direct
FM modulation {below}.
SELECTING SP/MIC JACK FUNCTION
Unless you connect the transceiver to a TNC or PC,
the default setting of the SP/MIC jack function (Menu
No. 9), ÒSP/MICÓ works fine.  However, if you want to
interface to a different type of peripheral, configure
the SP/MIC jack function:
1Press [MNU] to enter Menu mode.
2Turn the Tuning control or press [
]/ [] to select
Menu No. 9 (SP/MIC JACK).
3Press [
