Antenna connector adapterThe antenna connector of this radio uses an SM A terminal.Use an antenna connector adapter [SM A(f) – BNC(f) orSM A(f) – N(f)] for adjustment. (The adapter is not provided asan option, so buy a commercially-available one.)2. Repair Jig (Chassis)Use jig (part No.: A10-4082-03) for repairing the TK-2160.Place the TX-RX unit on the jig and fit it w ith screw s.The jig facilitates the voltage check and protects the finalamplifier FET w hen the voltage on the flow side of the TX-RXunit is checked during repairs.3. Battery Jig (W05-0909-00)+ Term inal (Red)– Term inal (Black)Connect the pow er cable properly betw een the battery jiginstalled in the transceiver and the pow er supply, and be sureoutput voltage and the pow er supply polarity prior to sw itchingthe pow er supply ON, otherw ise over voltage and reverseconnection may damage the transceiver, or the pow er 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. Refer to page 10 for details.Note: When using the battery jig, you must measure thevoltage at the terminals of the battery jig. Otherw ise, a slightvoltage drop may occur w ithin the pow er cable, betw een thepow er supply and t he bat t ery jig, especially w hile t hetransceiver transmits.+ Term inal(Red)– Term inal(Black)C3100/25VC2470P/25VC1100P/25VR11.8M–S+Pow ersupplyPow er cableSCHEM ATIC DIAGRAM
