4. Operating Instructions
4.1 Power On/Off
To power on the transmitters and receiver, simply remove them from the charging case. They will automatically power on and attempt to pair. To power off, place them back into the charging case.
4.2 Pairing
The transmitters and receiver are pre-paired at the factory. If re-pairing is needed, consult the on-screen instructions on the receiver or refer to the full digital manual on the SYNCO website.
4.3 Intelligent Noise Cancellation 2.0
The SYNCO G4 features 2.0 intelligent noise cancellation to reduce ambient noise. This function can be activated or deactivated via the controls on the transmitter or receiver, depending on the specific model variant. When active, it reduces noise from 90dB to 60dB, enhancing vocal clarity.

4.4 Backup Track Protection
The system includes a built-in -6dB safety channel. This feature records a secondary audio track at a lower volume, preventing audio clipping or distortion from sudden loud sounds during recording. This ensures a clean, usable backup track.

5. Maintenance
To ensure optimal performance and longevity of your SYNCO G4 system:
