Operation Introduction:

1. Pairing method: one-to-one frequency-locking pairing (mainly used in situations where multiple microphones are used at the same time, such as schools, shopping malls, and tour guides. The transmitter and receiver must be paired with one-to-one frequency locking first so that multiple devices work at the same time and have no serial frequency.)

2. One to one frequency lock pairing method: The current receiver must be turned off, then turn on the transmitter, and then press and hold the transmitter “–button until it displays l’888” and then release the button. After prompt tum on the receiver power, the green light on the receiver will be on after 3 seconds. At this time, the receiver-transmitter has successfully locked one to one. In the future, this receiver can only be connected to this transmitter, and other transmitters cannot be connected to this receiver.

3. Multi-device mode pairing method:
   1 drag 1 mode
   The wireless microphone 1 drag 1 mode supports 50 sets of wireless microphone use without cross-frequency and no interference: 50 transmitters must be tuned to different frequency bands A01, A02…A50. If multiple transmitters are turned on at the same time and there is cross-frequency interference. just long-press the “+” button for 1 second to convert to other frequency bands (such as frequency conversion to one of A02 or A03…A50) until the karaoke is normal.
   1 drag 2 modes (that is A microphone and b microphone are used at the same time)
   Wireless microphone 1 drag 2 mode supports 100 sets of wireless microphone use without cross-frequency and no interference: 100 sets must be tuned to different frequency bands of A01. A02…A50, or b01, b02…b50 respectively.
   “ A/b microphone channel switching: first press and hold the “-” key, then short press” “power on transmitter, it switches from A01 to b01 about 3 seconds; the same operation, b01 can also be switched to A01, as long as A and b are two One microphone frequency band is A01…or A50. and the other is b01…or b50.
   A wireless microphone A frequency band has a total of 50 frequency bands A01, A02…A50,
   b wireless microphone b frequency band has a total of 50 frequency bands b01. b02…b50:
   Just keep one wireless microphone in one of the frequency bands of A01. A02… or A50, and the other wireless microphone in one of the frequency bands of b01. b02… or b50; in this way, two wireless microphones can broadcast K songs and lectures at the same time (similar to KTV love songs) Duet).
   If there are multiple wireless microphones around you working at the same time and cross-frequency interference occurs, just press and hold the “+” button for 1 second to convert to other frequency bands (for example, A wireless microphone converts to one of A02 or A03…A50: B wireless microphone frequency conversion to one of b02 or b03…b50) until the live broadcast K song is normal.

4. POWER ON-OFF:
   Short press the ” “one-time power on. long-press the ” ” 3-second power off.

5. Turn Channel:
   Long press the “+” button for 1 second to turn the channel (for example, long- press the “+” button for 1 second to turn the channel from A01 to A02),

6. Volume adjustment:
   Short press the “+” or “-” button 1 time to Volume up or Volume down

7. ECHO set
   A Continuously press” ” 2 times to adjust echo, default is echo off (E00). a total of 6 levels (E01. E02… E06,E00).
