INSTALLATION /
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 power to the
transceiver on and off with the car ignition key.
If you use the Horn Alert function or the Manual Relay
function, you can turn the function off while driving with the
ignition key.
Modifying the Transceiver
Modify the transceiver as follows to turn the power or the
Horn Alert or Manual Relay function on and off with the ignition key.
1. Remove the lower half of the transceiver case.
2. Set jumper resistors (0Ω) R134 and R135 of the TX-RX unit
(A/2) as shown in Table 1.
Connecting the KCT-18 to the Transceiver
1. Install the KCT-19 in the transceiver.
2. Insert the KCT-18 lead terminal ( 2 ) into pin 3 of the square
plug ( 1 ) supplied with the KCT-19, then insert the square
plug into the KCT-19 connector ( 3 ).

INSTALLATION /
PA/HA Unit (KAP-1 : Option)
Installing the KAP-1 in the Transceiver
Modifying the Transceiver
Horn alert
The Horn Alert (max. 2A drive) and Public Address functions are enabled by inserting the KAP-1 W1 (3P; white/black/
red) into CN3 on the TX-RX unit, inserting W2 (3P; green) into
CN7 on the TX-RX unit, and connecting the KCT-19 (option) to
CN2 and CN3 of the KAP-1.
The signal from pin 4 of IC9 on the TX-RX unit turns Q5
and Q1 on and off and drives KAP-1 HA relay K2 to drive the
horn with a maximum of 2A.
The default output is HR1. The relay open output can be
obtained between HR1 and HR2 by removing R1 in the KAP1.
Installation procedure
1. Open the upper case of the transceiver.
2. Insert the two cables ( 1 ) with connectors from the KAP1 switch unit into the connectors on the transceiver.
3. Secure the switch unit board to the chassis with a screw
( 3 ). The notch ( 2 ) in the board must be placed at the
front left side.
4. Attach the cushion on the top of the KAP-1 switch unit.

Public address
The signal from pin 13 of IC9 on the TX-RX unit drives PA
relay in the KAP-1 and switches the audio power amplifier
output between the external PA system (through KCT-19) and
internal and external speakers.
To use the PA function, R153 on the TX-RX unit must be
removed.

Others
If the PA and HR2 are not necessary and the speaker output is output to an external unit through the KCT-19, connect
the KCT-19 C connector to CN8 on the TX-RX unit.

Transceiver Modification Procedure
install the foot switch
Install the foot switch through the KCT-19 and KCT-18.
When the switch is treaded on, the radio enters the emergency mode.
Change the power switch circuit

TX-RX unit (A/2) : RF section
R142 : Remove (RK73GB1J473J, 47kΩ)
Once the transceiver is modified, it cannot be turned on
and off with the power switch. The power switch turns the
LCD backlight and display on and off. (The power is switched
on and off by IGNITION SENSE.)

Test Mode Operating Features
This transceiver has a test mode. To enter test mode,
press [SCN] key and turn power on. Hold [SCN] key until
test channel No. and test signalling No. appears on LCD.
Test mode can be inhibited by programming. To exit test
mode, switch the power on again. The following functions
are available in test mode.

Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the unit
to a suitable power supply.
Whenever the transmitter is turned, the unit must be connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
4 dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
Transceiver tuning
(To place transceiver in tuning mode)
Channel appears on LCD. Set channel according to tuning requirements.
