Regulated Power Supply 5V to 10V, approx. 5AUseful if ammeter equipped■ 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 provided asan option, so buy a commercially-available one.)■ Battery Jig (W05-0909-00)Connect the power cable properly between the battery jiginstalled in the transceiver and the power supply, and be sureoutput voltage and the power supply polarity prior to switch-ing the power supply ON, otherwise over voltage and reverseconnection may damage the transceiver, or the power supplyor both.When using the battery jig in user mode, the transceiverassumes that a lithium-ion battery pack is attached to thetransceiver. In adjustment mode, battery type detection isnot performed.Note : When using the battery jig, you must measure thevoltage at the terminals of the battery jig. Otherwise, a slightvoltage drop may occur within the power cable, between thepower supply and the battery jig, especially while the trans-ceiver transmits.+ Terminal (Red)– Terminal (Black)■ Nut wrenchIn order to turn the volume nut and the channel selectornut, use a recommendation tool.KENWOOD part No. : W05-1123-00S–+C1100P/25VC2470P/25VC3100/25VR11.8M++Terminal(Red)–Terminal(Black)PowersupplyPowercableSchematic diagram
