. Noise reduction function, high Sefal/ noise ratio. Good signal output, low noise. Low distortion, wide frequency range. 4. Improved signal circuit and sound output. Good working distance, more than 50 meters without obstacles, obstacles about 10 meters. Thanks to the dual microphone design, you can use both without interference. The signal is less likely to be interfered with due to the channel switching system. The product is suitable for TV singing karaoke, rehearsal room, entertainment, etc. CONNECTION GUIDE 1. Place the microphone receiver near the audio or multimedia device. Connect the cable supplied with this product from the output of the microphone receiver to the sound input of the multimedia device. Our receiver has two antennas that have to be bent vertically to receive the signal correctly. It is recommended not to use the receiver in a very enclosed area to have a good microphone range. 2. Open the microphone tube and install two #5 batteries (always respect polarity). Then slip it back into the microphone tube. 3. Press the ON/OFF key of the host for 2 seconds, the indicator BP will light up, and the host will work normally. In this case, turn on the microphone, and the RF light of the host will be on, indicating that the received signal is normal. When you speak into the microphone, the AF light on the host will turn on, indicating that the audio signal is received normally. The four sets of volume knobs can be adjusted to the effect of personal fit.

FCC WARNING STATEMENT Changes or modifications not expressly approved by the party responsi-

ble for compliance could void the users authority to operate the equipment. 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 de-

signed to provide reasonable protection against harmful interference in a resi-

dential installation. This equipment generates uses and can radiate radio fre-

quency energy and, if not installed and used in accordance with the instruc-

tions, 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 en-

couraged to try to correct the interference by one or more of the following mea-

sures:

-- 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. 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 interfer-

ence that may cause undesired operation. The device has been evaluated to meet general RF exposure requirement.
