Once the BASE has power connection, place the transmitter in its cradle on the BASE. 2. Leave the transmitter on the cradle for at least 4 hours for a full charge. 3. Charge LED stays red during charging and turns green after full charge. PREPARING FOR INITIAL USE 1. Ensure that the fully charged before initial use. 2. Check line and power connections to the BASE. 3. Select the ON position of power switch 4. Push the TALK button of the transmitter to check the operation. OPERATION 1. Supply 12 VDC power into the BASE using the Car Battery. 2. 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. 3. 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. 4. 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. 5. 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 independently. When the siren turns on with master Transmitter, for example, the siren turns off if pressing toggle red button of slave Transmitter once. 6. When the distance between the Base and Transmitter is within the coverage range, In-Use LED stays on, but if the distance is out of the area, In-Use LED blinks and out-of-range beep sound is heard. There is beep on/off switch on the left side of Transmitter to mute the beep tone. 7. There are two microphones on a Transmitter. One is Internal Mic and the other is External. Basically Transmitter operates with Internal Mic, but when External Mic is plugged in the Jack on the top of Transmitter, Internal Mic switches off and External Mic switches on. When External Mic is removed or damaged, Internal Mic switches on automatically. SPECIFICATIONS
