Warning: This device complies with part 15 of the FCC Rules. Operation is 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. Changes or modifications to this unit not expressly approved by the party responsible for compliance will void the user’s authority to operate the equipment. Any change to the equipment will void FCC grant. 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 used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: --Reorient or relocate the receiving antenna. --Increase the separation between the equipment and receiver. --Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. --Consult the dealer or an experienced radio/TV technician for help. The equipment compliance with FCC radiation exposure limit set forth for uncontrolled Environment

TP256 Remote circuit description This transmitting circuit mainly separate three main parts: a. Main control (IC) b. From Audion (Q1), Surface Acoustic Wave F1, Chip inductor L1, electrical capacitance C2, C4 and electrical resistance R3 combine to become UHF frequency 433.92 MHz. c. Use Q2 switch audion to become a ASK modulation. Circuit description The main control is an internal 4 MHz MCU, all coding and function is control by software. When MCU receives “HELP” comment, the GPO will export 400US/800US code. The codes is controlled though the High/Low translator, it combine with Q1 audion, F1 Surface acoustic, L1 Chip inductor, C2 electrical capacitance for 433.92 MHz circuit transmit and not transmit to achieve ASK modulation. Vibration signal is though electrical capacitance ANTO1 and C6, C7, L3 combine a filter, then transmit out thought the antenna.
