User Manual 1 Brief introduction New microwave sensor is used as human body detector for automatic control of closestool. The sensor adopts frequency modulated continuous wave (FMCW} technique, so has higher ranging accuracy and stronger adaptability compared with doppler sensor. The sensor can detect distance and motion state of ambient human body in real time, and send corresponding signal to master controller of closestool to control automatic opening/closing of cover & seat and auto—flushing. 2 Datasheet 2.1 Pin function definition No. Label Color Description IN/OUT Voltage 1 VvCC Red Positive pole of IN 5V power supply 2 D—OUT Orange Digital output oUT 5V 3 GND Black Negative pole of IN GND {Thick) power supply 4 SDA Brown Data Iine. of I.ZC OUT/IN 3.3V communication 5 SCL Yellow Clock line of 12C IN 3.3V # 1R

Once target object moves in the distance of the preset gear, the sensor output pulse signal with special frequency, which would keep till the object moves out of the distance range. The period of the pulse signal is 50 ± 1ms, and the duty ratio of high/low electric level is 50% with high electric level of 5V. 5 Certification information 5.1 FCC/IC certification 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. 第 5 页

Note: This product 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 product 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. However, there is no guarantee that interference will not occur in a particular installation. If this product 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. Please take attention that changes or modification not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 5.2 RSS certification This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radioexempts de licence. L'exploitation est autorisée aux deux conditions 第 6 页

suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. The module is limited to OEM installation ONLY The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. When the FCC identification number or ISED certification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC ID: N82-KOHLER036” and the information should be also contained in the devices’ user manual. This device complies with Industry Canada’s RSS-310. Operation is subject to the condition that this device must not cause harmful interference and must accept 第 7 页

any interference, including interference that may cause undesired operation of the device. 第 8 页
