HMC- DN8 NFC - RG3 NFC - DL3 NFC - MQ4 NFC - SE Requirement Specifications User Manual DHS HMC NFC DL3 DHS HMC NFC MQ4 FCC ID: KR5-DHSHMCDL3MQ4 IC ID: 7812D-DHSHMCD3M4 HMC- DN8 NFC - RG3 NFC - DL3 NFC - MQ4 NFC - SE Requirement Specifications 1.3 Type of Sensor This sensor is a DHS. The DHS is a standalone module with double capacitive sensor, NFC and pocket lighting. This module is integrated into a DH, and used in Keyless Entry System, enabling 'key-
free' Vehicle Unlocking and Locking. 1.4 Sensor Functions The DHS has 4main functions :
- Unlock Function : Capacitive detection
- Lock Function : Capacitive detection
- Pocket lighting : Illumination of the pocket of the door handle. 1.5 Capacitive Sensing - Physical Principle The sensing principle is based on the measurement on an Electrode Capacitance (Cp) A human body approaching this Electrode creates an additional Capacitance (Cf) by coupling effect. The equivalent capacitance (Cp+ Cf) is then larger than Cp. The SW periodically measures the Electrode Capacitance with a defined technology. The SW can then process this information and decide to trigger or not a "DETECTION", based on the capacitance variation. 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 of the device. This device complies with Industry Canadas licence-exempt RSSs. 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 prsent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement.
