TheKCT-18 cable needs to pass through one of two indenta-tions located on the rear panel of the transceiver.(5) Cut off the projection of the top packing using a pair ofnippers or similar tool.If the KCT-18 cable is dressed to be routed through theindentations on the right side in step 5, the right side ofthe projection needs to be cut off. If the KCT-18 cable isdressed to be routed through the indentations on the leftside, the left side of the projection needs to be cut off.Following is a figure presenting an example for when theright side of the projection is cut off.(6) Reinstall the top packing. Check the correct fitting of thetop packing, then reinstall the cabinet and two screws forthe right and left sides.(7) Connect the other side of the KCT-18 to the ignition lineof the car.Installation Procedure: Method B(1) Remove the ACC. cap on the rear of the transceiver.(2) Connect the D-sub connector of the KCT-60 to the D-sub15-pin terminal of the transceiver.(3) Insert the crimp terminal side of the KCT-18 to pin 2 ofthe square plug.(4) Connect the square plug to the 15-pin connector of theKCT-60.(5) Connect the other side of the KCT-18 to the ignition lineof the car.Note:You must set up using the KPG-175D.2.3.4 External Speaker (Option)2.3.4.1 KES-3The KES-3 is an external speaker for the 3.5-mm-diameterspeaker jack.Connection procedure(1) Remove the speaker-jack cap on the rear of the trans-ceiver.(2) Connect the KES-3 to the 3.5-mm-diameter speaker jackon the rear of the transceiver.CutTX-RX unitComponent sideTop packing2KCT-18Square plugIgnitionline of the car131415101112789456123KCT-60
