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.
Connecting the KCT-18 to the Transceiver
1. Install the KCT-19 in the transceiver.
2. Insert the KCT-18 lead terminal ( ) into pin 3 of the square
plug ( ) supplied with the KCT-19, then insert the square
plug into the KCT-19 connector ( ).

Installing the KAP-1 in the Transceiver
The Horn Alert (max. 2A drive) and Public Address func-
tions 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.
Installation procedure
1. Open the upper case of the transceiver.
2. Insert the two cables ( ) with connectors from the KAP-
1 switch unit into the connectors on the transceiver.
3. Secure the switch unit board to the chassis with a screw
( ). The notch ( ) in the board must be placed at the
front left side.
4. Attach the cushion on the top of the KAP-1 switch unit.

Modifying the Transceiver
Horn alert
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 KAP-
1.

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.

Test Mode
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.
Controls
[PTT] Used when making a transmission.
[MON] Monitor on and off.
[SCN] Sets to the tuning mode.
[A] Function on.
[D/A] RF power high and low.
[] Changes signalling.
[] Changes wide and narrow
[CH /] Changes channel.
[Volume /] Volume up/down.
LCD indicator
“SCN” Unused.
“AUX” Lights at RF power low.
“MON” Lights at monitor on.
“Right side dot” Lights at narrow.
LED indicator
Red LED Lights during transmission.
Green LED Lights when there is a carrier.
Frequency and Signalling
The set has been adjusted for the frequencies shown in
the following table. When required, re-adjust them following
the adjustment procedure to obtain the frequencies you want
in actual operation.

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 con-
nected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
4dummy 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 tun-
ing requirements.
LCD display (Test mode)
Press [SCN], now in tuning mode. Use [D/A] button to
write tuning data through tuning modes, and [CH /] to
adjust tuning requirements (1 to 256 appears on LCD).
Use [ ] button to select the adjustment item through tun-
ing modes. Use [A] button to adjust 3-point or 5-point tun-
ing, and use [ ] button to switch between wide/narrow.
