TONOR TW621 Troubleshooting
Operational issues
Q:
The microphone isn't working and the receiver's RF indicator light isn't on.
How can I fix this ?
A:
Check if the microphone numbers are duplicated (Note: For TW630 and TW632, the microphone numbers A/B are not duplicated. For TW620, the microphone number is A, and for TW621, the beltpack number is B for normal operation).
If the numbers are correct, follow steps (2)-(5).
If the numbers are duplicated, follow steps (1)-(5)
1) Bodypack: Turn on the non-working bodypack, press the SET button first, then the power button, hold it down, and wait for the microphone screen to switch between A and B before releasing the buttons (approximately 5 seconds).
2) Turn off the receiver.
3) Microphone/Bodypack: Turn off the microphone/bodypack, press the microphone HI-LO button/bodypack SET button first, then the power button, hold it down, and wait for the screen to flash before releasing the buttons (approximately 5 seconds).
4) Turn on the receiver, click the microphone HI-LO button/bodypack SET button, and the RF indicator on the receiver will stay on, indicating that pairing is successful.
5) If there are multiple non-working microphones, repeat the above steps to fix them.
Q:
The microphone frequently disconnects during use and has a very short operating range. How can I fix this ?
A:
1) In an interference-free environment, the maximum operating distance is 60m. Keep the microphone and receiver in a straight line of sight as much as possible.
2) Switch the microphone to another frequency to avoid interference from nearby signals.
3) Keep the microphone and receiver away from interference sources such as mobile phones, radios, and other transmitting devices.
4) Do not place the receiver in a metal cabinet!
