OPERATION
8. Supply 12 VDC power into the BASE using the Car Battery.
9. 1) Separate the transmitter from the BASE and turn on the transmitter.
2) When In-Use LED blinks for a few seconds and stops blinking, communication channel between
Base and Transmitter has been set up. When In-Use LED keeps blinking, the communication
channel between Base and Transmitter does not match.
3) How to set up communication channel between Base and Master Transmitter
Put Transmitter on the Base for charging. Press and hold the Talk button on the Transmitter for
over 5 seconds. Release the Talk button and Green LED’s(In-Use LED)on both the Base and
Transmitter blink and a confirm tone is heard. Now communication channel has been set up and
Transmitter is ready to operate normally.
In case of setting up communication channel by Slave Transmitter, on the other hand, The In-Use
LED on Base does not blink and stays on.
4) Basically KT-24N allows the simultaneous usage of two transmitters.
Though one master Transmitter is used with one Base, optionally another Transmitter (Slave) can
be used. In short, one master Transmitter can be used with one Base, instead of using two master
Transmitters or two slave Transmitters with one Base.
Each of master Transmitter and slave Transmitter is marked on the label on each of the Transmitter.
10. When the In-Use LED on the top of Transmitter turns on by pressing the toggle Talk button, the
Transmitter transmits the audio signal and the Base outputs the active-high(12V) digital signal on
the Talk mode output pin.
Active-high or active-low on the bottom of the Base is selectable.
11. When the active-low digital signal is transmitted to the video-on input pin of the Base, Transmitter
turns on automatically. When input signal switches from active-low to high, Transmitter goes to
Standby mode automatically.
12. KT-24N has Emergency function. Whether Transmitter is either in Standby mode or In-Use mode,
Emergency function is operable. Siren turns on/off by pressing toggle red(EMG) button.
In case toggle red(EMG) buttons on both transmitters are pressed, the siren turns on/off not
