2. Horn Alert Function

The Horn alert function (max. 2A drive) is enabled by in-
stalling the KCT-60 in the transceiver.
2-1. Installation Procedure
1. Remove the chip resistor R863 (4.7kΩ) on the TX-RX unit
before installing the KCT-60 in the transceiver.

2. Remove the ACC. cap on the rear of the transceiver.
3. Connect the D-sub connector of the KCT-60 to the D-sub
15-pin terminal of the transceiver.
4. Insert the two crimp terminals of the Horn alert cable to
pins 13 and 14 of the square plug.
5. Connect the square plug to the 15-pin connector of the
KCT-60.
6. Connect the remaining two Horn alert cables to your car
Horn alert signal control.
The internal FET switch can be controlled by turning the
HA function on/off and by using a signaling decode out-
put. The maximum current of HA is 2A. This FET switch
is the open drain circuit. Therefore, a DC power supply is
necessary to use the HR1. The voltage range is from 5V
to 16V.

3. Ignition Sense Cable (KCT-18: Option)
The KCT-18 is an optional cable for enabling the ignition
function. The ignition function lets you turn the transceiver
power on and off with the car ignition key.
3-1. Installing the KCT-18 (Ignition sense cable) in
the transceiver
1. The KCT-18 can be installed in the transceiver by the fol-
lowing two methods (Method A, Method B).
Method A: The KCT-18 is soldered to the "IGN" pad on
the TX-RX unit.
Method B: The KCT-18 is connected to the 15-pin con-
nector of the KCT-60 connected to the trans-
ceiver.
