During work on and with the device the required personal protective equipment must always be worn. Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions. This device complied 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. Changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment. Authorised personal Appropriate use FCC Certification Warning: User must keep a safety distance of at least 20cm from the antenna. NOTE: 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. 2.Measurement Principle The extremely narrow microwave pulse emitted by the antenna on radar level instrument can travel at the speed of light and part of its energy, which is reflected off the surface of target medium, is received by the very same antenna. The time lapse between pulse emission and reception by the antenna is proportional to the distance between the surface of target medium and the reference point on antenna. However, due to the fact that the electromagnetic wave is transmitted at extremely high speed, which leads to the tiny time lapse (nanosecond level) and makes it difficult to be identified, GDRD series of radar level instrument have adopted a special demodulation technology, enabling itself to detect the time lapse between pulse emission and reception correctly, and eventually generate accurate measurement result. Principle The pulse radar level instrument, adopted K band range as transmission frequency, which make this series have specialties as below: Small beam angle, which centralize energy, make GDRD high ability of anti-jamming, hence high accuracy and reliable. Small antenna size, easy to mount and easy to equip extra dust protection. Small blind zone, good accuracy even for small vessels. Shorter wave-length, suitable for small power. Equipped with advanced microprocessor and unique EchoDiscovery echo processing technology, the radar level instrument can be used under various hazardous process conditions The pulse radar level instrument, with pulses as its working tool and extremely low emission power, can be mounted on various metal or nonmetal vessels, harmless towards the environment and human beings.

Warning statement to the user for keeping the safety distance from the antenna should be included in the user manual. The highest measured power including antenna gain is -11.3dBm(0.0741mW), hence the Maximum Permissible Exposure (MPE) value: 225 22 /1/10474.1 2014159.34 10741.0 4 * cmmWcmmW R GPout Pd Therefore the device is exclusion from SAR test, and compliance with MPE limit.
