Read these instructions carefully for correct use and retain it for reference in future. SYSTEM CONFIGURATION • 95 channels are possible in the 2400~2483 MHz bandwidth. • Transmission range reaches up to 350 meters in free area. • KT-24N conforms to RF regulations of FCC part 15. • Power: 12 VDC, Adaptor: For Charging 9VDC 400 mA Class 2 transformer wall adaptor provided. • Interconnection: RJ jack & cord provided • Dimension: Transmitter 66(L) × 46 (W) × 24 (H) mm BASE 80 (L) × 70(W) × 74 (H) mm • Color: black & black • Do not use this product near water, i.e., near a bathtub, wash bowl, kitchen sink or laundry Hub, in a wet basement, or near a swimming pool. • Do not use this product to report a gas leak in the vicinity of the leakage area. FEATURES • Longer range • Better voice quality • 95 channels operation • Auto on • Auto stand-by • 2 transimitters • Beep sound on/off switch • LED indicator for out of range warning • High performance chipset • Low battery LED indicator VCR Control BASE sleave master • Li-ion battery (3.7 VDC, 1200 mAh) • VCR on-work display • Internal & external microphone PIN DESCRIPTION OF THE BASE OUTPUT PORT Connector wire Pin #1 : MIC trigger (blue) Pin #2 : Panic Trigger (black) Pin #3 : Inside car mic trigger(yellow) Pin #4 : GND(orange) Pin #5 : 12V VDC_IN (red) Pin #6 : VIDEO_ON (brown) Audio jack Pin #1 AUDIO_GND Pin #2 AUDIO_OUT (output from the port) Pin #3 car mic out CHARGING THE BATTERY (FULL CHARGE) 1. 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 1. Frequency Hoping / RF channel exclusion / Dual slot Antenna Diversity 2.

FCC ID: PE3KT-24NT REPORT #: THRU-803002 1 of 27 TEST PROCEDURE BANDWIDTH 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth and the span set as shown on plot. POWER OUTPUT: The RF power output was measured conducted. ANTENNA CONDUCTED EMISSIONS: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10MHz and the spectrum was scanned from 30 MHz to the 10 th Harmonic of the fundamental. Above 1GHz the resolution bandwidth was 1 MHz and the VBW = 3 MHz and the span to 50 MHz. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-2003 using an Agilent spectrum receiver with pre-selector. The bandwidth (RBW) of the spectrum receiver was 100kHz up to 1 GHz and 1 MHz above 1 GHz with an appropriate sweep speed. The VBW above 1 GHz was 3 MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna.
