Operationmanual DX6-DR / DX6-TF Dual-Channel Three Redundancy Digital Wireless Microphone System 1 DX6-DR / DX6-TF Dual-Channel Three Redundancy Digital Wireless Microphone System Important safety instructions ◼ READ, KEEP and HEED these instructions. ◼ CLEAN ONLY with dry cloth. ◼ DO NOT block any ventilation openings. Allow sufficient distances for adequate ventilation and install in accordance with the manufacturer’s instructions. ◼ DO NOT install or place near any heat sources such as open flames, radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. ◼ DO NOT defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wider blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. ◼ PROTECT the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. ◼ ONLY USE attachments/accessories specified by the manufacturer. ◼ USE only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. ◼ UNPLUG this apparatus during lightning storms or when unused for long periods of time. ◼ REFER all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, or does not operate normally. ◼ To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. ◼ Do not attempt to modify this product. Doing so could result in personal injury and/or product failure. Federal Communication Commission Interference Statement 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 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 Caution: To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 0.5 centimeters between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 0.5 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. 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 CE ◼ Frequency: 2402~2480MHz, Maximal power: 20 mW (DX6-TF) ◼ CE declaration info: www.chiayo.com.tw/declaration.html 2 Instructions Thank you for choosing FITNESS AUDIO digital wireless microphone system! For more details, please take a few moments to read this operating manual for thorough understanding of the function and operation of both transmitter and receiver.

Refer to Fig.1 on P.4) square fixing plate (1XA1027) (Refer to Fig.2 on P.4) operation manual **The above specifications are subject to change without prior notice. Important usage instructions ◼ To cope with the complicated 2.4GHz wireless environment, the line-of-sight distance between the microphone and the receiver should be shortened to ensure that the signal is not blocked. ◼ When one receiver is used with two microphones, it is recommended that the microphones be set to A-SCAN mode. (Please refer to P13) ◼ When two receivers are used with four microphones, the microphones should be set in F- CH01~F-CH04 modes respectively and the modes cannot be repeated. (Please refer to P13) ◼ The A-SCAN mode and F-CH01~F-CH04 mode cannot be mixed in the same system. ◼ When the system encounters interference or signal interruption, try the following:  The microphone enters the A-SCAN function page and scans to search for the best available channel.  The receiver should be kept at least 5 meters away from other WiFi, Bluetooth or 2.4GHz devices in use.  Keep the distance between the microphone and the receiver at l…

Page 2 of 30 1 General Information 1.1 Notes The purpose of conformity testing is to increase the probability of adherence to the essential requirements or conformity specifications, as appropriate. The complexity of the technical specifications, however, means that full and thorough testing is impractical for both technical and economic reasons. Furthermore, there is no guarantee that a test sample which has passed all the relevant tests conforms to a specification. Neither is there any guarantee that such a test sample will interwork with other genuinely open systems. The existence of the tests nevertheless provides the confidence that the test sample possesses the qualities as maintained and that is performance generally conforms to representative cases of communications equipment.
