Instruction Manual 1.Matching code: (Figure 1) Step1.Press and release the required channel corresponding switches (SW1/SW2), and the corresponding LED will long bright. (SW1 corresponds to LED1, SW2 corresponds to LED2) Step2.Press the required button on the remote control within 30 seconds, and the receiver corresponding LED will turn off. Step3.Then when you pressed the learn button(which one has already learned) every time, the receiver corresponding LED will flash 2 times and have relay sounds along with, indicating that the match code is OK. 2.Clearing code: 1).Single channel clear code: Press the receiver SW1/SW2 button for 5 seconds, LED1/LED2 flash 7 times and then turn off. (Figure 2) 2).All channels clear code: Press the receiver SW3 button for 5 seconds, LED1 and LED2 flash 7 times at the same time and then turn off. (Figure 3) Figure 1 Figure 2 Figure 3 x7 x7 FCC Warnning: 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 againstharmful interference in a residential installation. This equipment generates, uses and can radiateradio frequency energy and, if not installed and used in accordance with the instructions, maycause harmful interference to radio communications. However, there is no guarantee thatinterference will not occur in a particular installation. If this equipment does cause harmfulinterference to radio or television reception, which can be determined by turning the equipmentoff and on, the user is encouraged to try to correct the interference by one or more of thefollowing 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. Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. 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. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 0cm between the radiator and your body.
