Antenna connector adapterThe antenna connector of this radio uses an SMA termi-nal.Use an antenna connector adapter [SMA(f) – BNC(f) orSMA(f) – N(f)] for adjustment. (The adapter is not providedas an option, so buy a commercially-available one.)NoteWhen the antenna connector adapter touches the knob,draw out the knob to mount the connector.2. Universal connectorUse the interface cable (KPG-36) for PC tuning or the leadwire with plug (E30-3287-08) and screw (N08-0535-08) forpanel tuning. Connct the plug to the universal connector ofthe radio and tighten the screw.The lead wire with plug (E30-3287-08) and screw (N08-0535-08) terminals are as follows. Numbers are universalconnector terminal numbers.Caution1. When connecting the plug to the universal connector ofthe radio, a short circuit may occur. To provent this, besure to turn the radio POWER switch off.2. Since the RX AF output is a BTL output, there is a DCcomponent. Isolate this with a capacitor or transformeras shown in the figure.3. Do not connct an instrument between red or black andGND.• Universal connectorADJUSTMENTUniversal connector1: SSW3: SP–5: EMC7: PTT9: NC11: 5M13: RXD2: SP+4: MSW6: ME8: PF10: E12: TXD14: NC
