National Electronics & Watch Co,. Ltd. Bike Speed & Cadence Sensor Installation How to install the Bike Speed & Cadence sensor • Place the Speed sensor on the rear chain-stays. Loosely attach the sensor using two cable ties. Note: Place the rubber pad in between the Speed sensor and the Chain-stays for stability. • Attach the Spoke magnet to the spoke. The speed sensor must be within 5 to 10 mm. of the spoke magnet. • Place the Cadence sensor on the front chain-stays. Loosely attach the sensor using two cable ties Note: Place the rubber pad in between the Cadence sensor and the Chain-stays for stability. • Attach the Pedal magnet to the spoke. The Cadence sensor must be within 5 to 10 mm. of the spoke magnet. -Working temperature: -10 deg. to +50 deg. CAUTION RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. National Electronics & Watch Co,. Ltd. Hereby, National Electronics & Watch Co. Ltd declares that this device is in compliance with the essential requirements and other relevant provisions of Directive 1999/5/EC. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada. 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. NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications or changes to this equipment. Such modifications or changes could void the user’s authority to operate the equipment. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions 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. This Class B digital apparatus complies with Canadian ICES-003. Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada. Since the output power is so low, no SAR measurement is required.
