NOTE: 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. FCC 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 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. RF exposure compliance statement: This device has been evaluated to meet the general RF exposure requirement 7 See solution Power supply ,cable or radio frequency Gain ,cable ,reduce interference or radio frequency Radio frequency Interface locking problem There is no sound A weak or distorted sound Working distance is too short ,sudden noise or signal frequency loss Unable to turn off the transmitter or change the frequency settings ,or unable to program for the receiver Power Supply Ensure that the receiver and transmitter use sufficient voltage. Test battery indicator. Please replace the battery or charge it. gain The front of the receiver adjusts the system gain. It corresponds to the input of mixing panel, amplifier or processor. Cable Make sure all cables and connectors are fully engaged or locked in place, Check whether the cable is damaged. If necessary, please replace it. Interface locking Transmitters and receivers can be locked to prevent accidental or unauthorized changes. When accessing the lock controller, the lock icon on the display screen. Unlock the receiver or transmitter according to instructions. Radio Frequency (RF) The RF green light lights up when the linked transmitter is within the range of the receiver. Measure transmitter range before performance to avoid operating beyond specified transmitter range. The RF meter bar indicates the received RF power, Signals may be received from receivers or from interference sourc- es such as television broadcasting. If the signal level is dis- played on the meter when the transmitter is off, there may be interference in the channel, Check whether there are in- terference sources in the area around the fender or change the receiver to clear frequency. Red display, weak reception. Green display, strong reception. Eliminating Radio Frequency Overpower If the radio frequency 0L icon appears on the radio frequency scale, please try the following operation. Reduce transmitter RF power level from Hi to Lo. Move the transmitter to a position at least 6m(20in) from the receiver. If active antenna is used, the gain of antenna or amplifier should be reduced. Using omnidirectional antenna. Increase the scope Increase transmitter RF power level to Hi. Increase the radio frequency range by using an active directional antenna, an antenna distribution system, or other antenna accessories Frequency compatibility Perform "scan" and "synchronization" operations to ensure that transmitters and receivers are set to the same channel or frequency. Check tags on transmitters and receivers to ensure they use the same band. Reducing interference Perform a scan to find the optimal idle frequency. Perform IR synchronization to transfer settings to the transmitter. If there are multiple systems, make sure that each receiver is assigned to a unique channel. If two transmitters are set to phase The same channel will cause interference. It should be ensured that there are no obstacles in the line of sight between the transmitter and the receiver. Keep the receiver antenna away from metal objects or other radio frequency interference sources (such as CD players, computers, digital effects, network switches, wires and personal stereo monitors (PSM) and other wireless systems). Eliminate excessive RF signal (see below).
