Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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 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 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. FCC Radiation Exposure statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. FCC Radiation Exposure statement - Hub This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. zircon.comzircon.com112 2 Get to Know Your Leak Alert ™ 360 Charging Hub with Integrated Alarm + Sensor *Internal rechargeable Li-ion Battery Wireless Charging Base USB-C Power Input Internal 85 dB Audible Alarm LED Status Indicators (Find more details at leakalert360.com) *Slow Flash – Pairing *Solid RED Leak *Battery Charging Flash Charging Hub Push Button *On/Off, Status Display, Enter Pairing Mode, Silence Alarm LED Status Indicator *Slow Flash – Pairing *Solid RED Leak *Battery Charging Flash QR Setup Code on Back Precision Water Sensors on back 8 Warnings Indoor use only. Devices not rated for outdoor use. Stop using the battery if it overheats, is damaged, dropped, or modified. Only use the charger supplied with sensors. No self-repairs. Contact the manufacturer for service. Non-replaceable battery – Do not remove, alter, or replace the battery yourself. Keep batteries away from liquids, oils, and extreme heat or cold. Do not use product that is damaged or repaired. Use only a power supply rated at 5V DC, 2A. Using a power supply with incorrect voltage or current may damage the device and void the warranty. Ensure the power supply is certified and compliant with local electrical safety standards. Do not use USB ports from computers or low-power adapters unless they meet the required specifications. Temperature Guidelines To ensure optimal performance and safety, please observe the following temperature limits: Operating Temperature: −10°C to 50°C Charging Temperature: 0°C to 45°C Storage & Transportation Temperature: −15°C to 60°C Using, charging, or storing the device outside these temperature ranges may result in reduced performance, damage, or safety hazards. Cautions Keep battery charged. Recharge the sensor battery once a year or when the low-battery warning appears. Set the detector flat on the floor with the sensing contacts facing down. Avoid metal surfaces. Don’t place the detector on metal; it can cause false alarms. Store and charge batteries in a cool, dry place. Transport and store lithium-ion batteries separately from metals (keys, coins, screws, nails) and liquids. Proper Disposal Don’t throw batteries in the trash – Take them to a battery recycling center or approved collection bin in your local area. zircon.comzircon.com310 7 Full Guide Switches and LED Indicators DEVICEINDICATOR BT Pairing / Setup BT Pairing / Setup BT Pairing / Setup Leak Charging Hub + Integrated Alarm LeakSensor LeakAlarm Battery Charging Battery Charging Battery Charging Firmware Update Firmware Update Firmware Update Other Other Other STATUS Pairing Mode Pairing Mode Pairing Mode Leak Detect…
