2.3 INSTALLATION
2.3.1 Connection Cable (KCT-60: Option)
The KCT-60 connection cable kit is used to connect the trans-
ceiver to a Horn alert cable, KCT-18 (Ignition sense cable), KES-
5 (External speaker), or through the KCT-36 extension cable.
2.3.1.1 Installing the KCT-60 (Connection cable) in the
transceiver
(1) Remove the ACC. cap on the rear of the transceiver.
(2) Connect the D-sub connector of the KCT-60 to the D-sub
15-pin terminal of the transceiver.
(3) Connect the 15-pin connector of the KCT-60 to a Horn alert
cable, KCT-18, KES-5, or through a KCT-36 extension ca-
ble.
Note:
You must set up using the KPG-175D.

2.3.2 Horn Alert Function
The Horn alert function (max. 2A drive) is enabled by installing
the KCT-60 in the transceiver.
2.3.2.1 Installation Procedure
(1) Remove the ACC. cap on the rear of the transceiver.
(2) Connect the D-sub connector of the KCT-60 to the D-sub
15-pin terminal of the transceiver.
(3) Insert the two crimp terminals of the Horn alert cable to pins
13 and 14 of the square plug.
(4) Connect the square plug to the 15-pin connector of the
KCT-60.
(5) 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 output. 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.
