Installing the KCT-19 in the transceiver

1. Accessory Connection Cable

(KCT-19: Option)

The KCT-19 is an accessory connection cable for connecting external equipment. The connector has 15 pins and the necessary signal lines are selected for use.

1-1. Installing the KCT-19 in the transceiver

1. Remove the upper and lower halves of the transceiver case, and lift the DC cord bushing ( 1 ) from the chassis.

2. Remove the pad as shown in Figure 1 ( 2 ).

3. Insert the KCT-19 cable ( 3 ) into the chassis ( 4 ). The wire harness band ( 5 ) must be inside the chassis. Replace the DC cord bushing ( 6 ).

Connect the KCT-19 to the TX-RX unit (A/2) as shown in Figure 2 ( 7 ).

Connect the KCT-19 to the external accessory by inserting the crimp terminal ( 8 ) into the square plug ( 9 ), both of which are supplied with the KCT-19.

Notes

This setup excludes adding an external speaker to provide audio at the remote microphone location. Therefore, do not connect KCT-19 cable C to transceiver at CN8. This will leave the speaker on the transceiver active.

If an external speaker is needed at the remote microphone location, you can connect KCT-19 cable C to transceiver at CN8 and tie into the black cable going to the speaker on the transceiver. Doing this will leave the speaker on the transceiver active as well as the remote speaker. Use two unused wires from the cat-5 cable (white/brown & brown ?) to run the audio from the KCT-19 to the remote speaker. KCT-19 port 12 is Speaker Audio Out.

If you only want the remote speaker to work and the speaker on the transceiver deactivated, disconnect the speaker on the transceiver and plug the KCT-19 cable C in at CN8 (see figure 2 above).
