SMUKT6898YDWIRELESS DOOR CHIME

USE MANUAL Brief Account THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATIONIS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION. The Device Data Product: Wireless Door Chime Frequency: 433.768MHz Power: A23, 12V Use Description The ultra-distance remote control (30metres long) meets the need of various buildings. And the doorbell must match the device to use. Part Description 1. Pushbutton 2. Pilot Lamp 3. Battery Press the key “1”, the doorbell will make the combination of the quadric-partial tone. When the key “1” is pressed, the pilot lamp will light and it will go out as soon as the key is released. Caution Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Be sure not to let it close to any metal object or expose it to rains. Description of the circuits Schematic Operation specification for remote controller 2262 is a coding integration element, it’s pins No. 1-8 are used for users, so the code can be coded discretionally by dip switches (but it should be consist with the mainframe code). When user operates the remote controller, press the switch, then power supply is gotten, and circuit works. 2262 sends code from pin 17 to shooting module with impulse form. According to the signal, H 10 at shooting module works. Then the signal is sent over. This is so-called coding.

Operational description for KT6898Y-D Wireless Door Chime 1. What the KT6898Y-D does? KT6898Y-D is a portable wireless remote control. It can control the receiver, which is away from the remote controller 30meters long. The receiver can make the combination of the quadric-partial tone. 2. Block Diagram Step: 1) Push the button and it will make the IC (HX 2262) and Triode work. At the same time, the LED lights. 2) The IC modulates the carrier. The signal generated by oscillator (The oscillator generates carrier in 433.768 MHz.) and the code generated by the IC is sent from pin 17 to the base of the Triode. 3) The Triode magnifies the signal comes from IC to the inbuilt antenna. 4) The inbuilt antenna generates RF signal. 3. Specification: 1) Type of modulation: Pulse 2) Pulse cycle: 56.40ms 3) Duty cycle: 9.54dB 4) Antenna: Amplify RF signal. 5) Ground: The negative pole of battery is grounding.
