To do so,the microphones are equipped with a sic-axis gyroscope sensor. FEATURES: 1. Energy Saving The six-axis gyroscope senses speed in three directions as well as any angular changes in velocity. This information is transmitted through the sensor and minimizes power consumption by entering a “sleep mode” when it senses no movement within a preset time,allowing for more usage time without changing batteries as often as conventional microphones. 2. Instant “wake up”Response The microphone can switch from “sleep mode” to operating mode in milliseconds with its intelligent sensory technology. 3. Auto-Mute When Not Held The microphone detects and auto-mutes when it is dropping. This function can avoid most unwanted noise and greatly decrease the chances of any damage to the audio equipment. It is important to note the auto mute function will engage once the sensor detects a falling motion (the minimum falling distance for the sensor to activate is 12 inches/30cm). The microphone will operate normally again once it’s picked up. HOW TO TURN AUTO-MUTE ON/OFF step 1: When the display show the frequency .press the "POWER" key .then will closed the received . step 2: press the "POWER" key for a while .the window of the power off disappear .

RF Exposure evaluation FCC ID: 2A5XU-U20 1.1. Applicable Standard According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1093 RF exposure requirement KDB447498 v06: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 1.2. Requirement According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 Standalone SAR test exclusion considerations: “Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition, listed below, is satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions.22 The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, typically in the SAR measurement or SAR analysis report, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for the SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions; for example, handheld PTT two-way radios, handsets, laptops & tablets etc.23 “ [(max. power of channel, including tune-up tolerance, mW)/ (min. test separation distance, mm)] · [√f (GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f (GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. 1.3.
