65 Precautions (1)The water meter installation must meet the GB / T 778.2 installation requirements, the cooper inline pipe should 5 times-diameter distance to the upstream and 3 times-diameter distance to the downstream. (2)The piping flow should be in the same direction as the logo arrow on the water meter (3) Wired communication of the ultrasonic water meter M-BUS wiring without polarity requirements, but must ensure that the wiring is solid and reliable, and pay attention to do waterproof moisture treatment. Line joints do not bear the tension, or easily to pull off joints caused by communication disconnect. (4) Wireless communication of ultrasonic water meters should not be installed in strong lines and other highelectromagnetic radiation near the source, otherwise it will affect the reliability of wireless signal transmission. (5) Ultrasonic water meter is a measuring instrument, must be in accordance with national standards for ultrasonic water meter for regular verification, and replace the battery before lifespan ran out. (6) Without the permission of manufacturer, no one shall dismantle the maintenance ultrasonic water meter, otherwise the warranty service shall be discharged. 6 After-sales service Free warranty: 2 years The warranty start time is based on the order contract time or the date of manufacture of the product.Original seal damage is not warranty.Due to improper use and maintenance of the product caused by failure or damage is not warranty.Damage caused by force majeure, such as war and natural disasters. won’t warranty.
7FCC Warning 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. Any 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 wit h the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are desi gned to provide reasonable protection against harmful interference in a residential installation. T his equipment generates uses and can radiate radio frequency energy and, if not installed and us ed 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 interfere nce 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 co nnected. -Consult the dealer or an experienced radio/TV technician for help.The device has been evaluate d to meet general RF exposure requirement. The device can be used in portable exposure conditi on without restriction. FCC ID: 2ANQO-DN20
