MDXRF1012Automobile Alarm Transceiver

Federal Communications Commission (FCC) Statement The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment. You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment. Federal Communications Commission (FCC) Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment.

RF1012 The encoder generates a digital code serially transmit (typical designation) when press any button into the Central Processor Unit (modulator or called as mixer) stage in circuit. The serially digital signal mixed with the carrier at modulator (mixer) stage by way of FSK mode (Frequency Modulation) and to the Transmitter antenna. The modulation depth is designed such as ± 5KHz in this application, that means the pulse (may be at high level state or low level state) will trigger the oscillator to generate a frequency at a specified fundamental frequency +5KHz or −5KHz, depended on the designation. For example, if the carrier frequency defined as fundamental frequency +5KHz at high level state, then the alternative carrier frequency will be fundamental frequency −5KHz at low level state. The Central Processor will trigger the oscillator to generate a carrier frequency when receive the signal. HT-491 The encoder generates a pulse code serially transmit (typical designation) when press any button into the Central Processor Unit (modulator or called as mixer) stage in circuit. The pulse signal mixed with the carrier at modulator (mixer) stage by way of Pulse Modulation and to the Transmitter antenna. The Central Processor will trigger the oscillator to generate a carrier frequency when any button was press and show the button on the LCD display.
