there is no signal indication.
② Turn on a mic and ensure that the first mic is functioning properly in its actual operating position.
③ Keep the first mic open and observe the RF signal indication of the second channel (repeat the
steps from the first channel to confirm the absence of interference signals).
④ Activate the second mic and ensure its proper functioning in its actual operating position. Repeat
this process for subsequent mics, ensuring that the previously set mics remain open. Repeat steps 2,
3, and 4 until all mics have been set up.
⑤ After completing the above steps, individually turn off each mic and check if the corresponding
channel's RF indicator shows any signal (normally, there should be no signal indication. If there is a
signal indication, continue to change the frequency.) Repeat this check for each channel.
If there is a need to replace mics due to damage or loss, simply use spare mics and perform frequency
pairing with the receiver.
the first channel on the receiver. If there is a signal present, it indicates interference. Adjust until
4. Precautions
① Large metallic objects, walls, ceilings, and other reflective surfaces, as well as human bodies, can
weaken the direct signal of the mic.
② Avoid installing the mic system near devices that may generate strong electromagnetic fields, such
as microwave ovens, induction cookers, electric motors, generators, etc.
③ Stay away from switch power circuits, RF circuits, and high-frequency pulse circuits, such as LED
screens, high-power transmitters, walkie-talkies, high-voltage generators, ion generators, etc. LED
screens, in particular, contain numerous switch power supplies that can significantly affect the
operation of the receiver.
④ Do not install the wireless mic system in the same cabinet as other devices, especially those with
switch power supplies or transmitters, such as DVD players, karaoke machines, power transformers
of equipment, switch power supplies, etc. When installing the wireless mic, follow the principle of
isolation and try to keep a distance of at least 50 centimeters from other devices that may cause
electromagnetic interference. For larger interference sources like LED screens, it is generally safer to
maintain a distance of over 5 meters.
⑤ The signal strength of the mic weakens as the distance between the mic and the receiving antenna
increases, especially in the presence of obstacles between them.
