Audio Generator (AG) Frequency Range 50Hz to 5kHz or moreOutput 0 to 1V10. Distortion Meter Capability 3% or less at 1kHzInput Level 50mV to 10Vrms11. 8Ω Dummy Load Approx. 8Ω, 3W12. Regulated Power Supply 5V to 10V, approx. 5AUseful if ammeter equipped■ Universal connectorUse the interface cable (KPG-36) for PC tuning or the leadwire with plug (E30-3287-18) and screw (N08-0535-08) forpanel tuning. Connect the plug to the universal connector ofthe radio and tighten the screw.The lead wire with plug (E30-3287-18) 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 prevent this, besure to turn the radio POWER switch off.2. Since the RX AF output is a BTL output, there is a DC com-ponent. Isolate this with a capacitor or transformer asshown in the figure.3. Do not connect an instrument between red or black andGND.1: SSW3: SP–5: EMC7: PTT9: OPT11: 5U13: RXD2: SP+4: MSW6: ME8: PF10: E12: TXD14: NC• Universal connector
